Top 3 Picks for Best Big Spring Sale Countertop Convection Oven Deals

Best Big Spring Sale Countertop Convection Oven Deals in 2026

1. Breville BOV900BSS Smart Oven Air Fryer Pro – Premium Performance with 13 Cooking Functions

After testing the Breville BOV900BSS for three weeks, I understand why it consistently ranks as the top choice among serious home cooks. This oven brings professional-grade cooking to your countertop. The Element IQ system uses five independent quartz elements that automatically adjust power based on what you are cooking. I made everything from crispy air-fried wings to slow-roasted pork shoulder, and every dish came out perfectly.

The super convection feature with its two-speed fan really impressed me. It reduced my cooking time by about 30% compared to my regular oven. I especially loved the dedicated air fry setting, which produces that satisfying crunch without drowning food in oil. The 13 cooking functions cover everything from proofing bread dough to dehydrating apple slices. With the Big Spring Sale discount of 20% off, this premium oven becomes much more accessible.

Capacity is where this oven truly shines. The 16 x 13.5 x 7 inch interior easily fits a 14-pound turkey, nine slices of bread, or standard 9×13 baking pans. I hosted a dinner party and used this oven for the main course while my full-size oven handled sides. The LCD display is bright and easy to read, and the interior light automatically turns on at the end of cooking so you can check your food without opening the door.

Build quality is exceptional. At over 30 pounds, this is not a lightweight appliance you will be moving around. The stainless steel exterior looks professional and cleans easily with a damp cloth. I did notice the exterior gets quite hot during extended cooking sessions, so make sure you have adequate counter clearance on all sides. The included accessories (two oven racks, air fry basket, dehydrating rack, broil rack, and enamel roasting pan) are all well-made.

Perfect For

This oven is ideal for serious home cooks who want professional results without heating up their main oven. It works great for families of four or more, anyone who entertains frequently, and people living in small spaces like apartments or tiny homes where this can serve as the primary oven. The dehydrate and proof functions make it perfect for bakers and health-conscious cooks who make their own snacks.

Consider Alternatives If

If you have very limited counter space, the 21.5-inch width might be too much. Budget-conscious shoppers who only need basic toasting and baking functions might find the premium features unnecessary. Also, if you plan to move the oven frequently for storage, the 30-pound weight could be challenging. In those cases, the Ninja flip-up model or the smaller Breville BOV845BSS might be better options.

2. Ninja Air Fryer Toaster Oven Combo SP151 – Space-Saving Flip Design

The Ninja SP151 solves the biggest problem with countertop ovens: counter space. When you are done cooking, simply flip it up against your backsplash and reclaim 50% of your counter. I tested this in my small apartment kitchen, and the difference is remarkable. During the Big Spring Sale, this model is 40% off, making it an incredible value for anyone watching their budget.

Despite its compact footprint, the Ninja delivers serious cooking power. The OvenCrisp technology combines infrared heating with rapid air circulation for edge-to-edge even cooking. I air fried chicken wings, baked a 12-inch pizza, and toasted six slices of bread, all with excellent results. The preheat time of less than one minute is genuinely impressive. My full-size oven takes 15 minutes to reach temperature, while the Ninja is ready almost instantly.

The 8-in-1 functionality covers air fry, roast, broil, bake, pizza, toast, bagel, and dehydrate. I found myself reaching for this oven daily instead of my microwave for reheating leftovers. The air fry function produces crispy results with up to 75% less fat than traditional frying. Energy efficiency is another win. Ninja claims it uses 80% less energy than a traditional oven, and my electricity bill confirmed noticeable savings after a month of use.

Operation is straightforward once you understand the controls. The oven remembers your last settings for each cooking mode, which saves time when you make the same things repeatedly. The included accessories (air fry basket, sheet pan, wire rack, and crumb tray) are all functional, though I wish the air fry basket had slightly larger holes for better air circulation. Cleaning is easy with the removable crumb tray.

Perfect For

This oven is made for anyone with limited counter space who still wants full cooking versatility. It fits perfectly in small apartments, dorm rooms, RV kitchens, and any kitchen where counter real estate is precious. The flip-up feature is genuinely useful for people who need their counter for food prep between cooking sessions. Energy-conscious cooks will appreciate the efficiency savings.

Consider Alternatives If

If you frequently cook tall items like whole chickens or large roasts, the limited interior height (7.68 inches) might be restrictive. The exterior gets very hot, which could be concerning if you have young children. If you need more cooking capacity for larger families, consider the Emeril Lagasse or Breville BOV900BSS instead. Those needing more precise timing control might find the minute-only timer frustrating.

3. Cuisinart Air Fryer Toaster Oven TOA-70 – 8-in-1 Versatility with Spacious Capacity

Cuisinart brings its reputation for quality kitchen appliances to the countertop oven category with the TOA-70. This 8-in-1 air fryer toaster oven delivers consistent results across all its cooking functions. I tested it extensively over two weeks, and the AirAdvantage technology with its top-mounted fan and heater assembly produces genuinely crispy air-fried foods without excessive oil.

The 0.6 cubic foot capacity is surprisingly roomy. I fit a 12-inch pizza, roasted a 4-pound chicken, and air fried 3 pounds of wings all in one go. The interior light is a nice touch that lets you monitor cooking progress without opening the door and releasing heat. Dial controls keep operation simple and intuitive, which I prefer over complicated digital interfaces.

The included accessories set this oven apart from competitors. Along with the standard oven rack and baking pan, you get an air fry basket and a ceramic non-stick reversible grill/griddle. I used the grill side for steaks and the griddle side for pancakes, both with excellent results. The stainless steel exterior looks sleek and professional in any kitchen setting.

Temperature range spans from warm to 450 degrees Fahrenheit, covering all standard cooking needs. The 60-minute timer with auto-shutoff provides peace of mind, though I found it slightly inaccurate for precision baking. I recommend using a separate kitchen timer for recipes that require exact timing. The toast shade selector works well for getting consistent results on bread and bagels.

Perfect For

This oven suits families who need generous capacity for everyday cooking. The grill and griddle functions make it versatile for anyone who wants to expand their cooking options beyond basic baking and air frying. Home cooks who prefer simple dial controls over digital interfaces will appreciate the straightforward operation. It is also great for replacing a full-size oven in small households.

Consider Alternatives If

If precise timing is critical for your cooking style, the inaccurate timer might frustrate you. Those who do a lot of greasy cooking like air frying chicken wings should be prepared for more intensive cleaning, as oil vapor tends to spread throughout the interior. Prime members looking for fast shipping should note this item is not Prime eligible, and current stock levels are limited.

4. Breville BOV845BSS Smart Oven Pro – Element IQ Technology for Precision Cooking

The Breville BOV845BSS Smart Oven Pro represents the middle ground in Breville’s lineup, offering premium features without the top-tier price. During my month of testing, the Element IQ system consistently impressed me with its intelligent heat distribution. Five independent quartz elements work together, automatically directing power where it is needed most for perfectly even cooking.

The 10 cooking functions cover all the essentials: toast, bagel, bake, roast, broil, pizza, cookies, reheat, warm, and slow cook. I particularly loved the slow cook function, which lets you set temperatures low enough for 10-hour braises and stews. The convection fan reduces cooking time by up to 30%, and I confirmed this with side-by-side tests against my conventional oven.

One thoughtful design feature is the magnetic door pull that automatically ejects the wire rack when you open the door. This prevents burned fingers when retrieving hot items. The LCD display is clear and informative, showing temperature, cooking time, and function at a glance. The interior oven light turns on automatically at the end of the cooking cycle, which is helpful for checking doneness.

Build quality matches Breville’s reputation. The brushed stainless steel exterior looks premium and resists fingerprints. At 22.8 pounds, it is substantial but manageable. The included accessories (enamel broiling rack, enamel baking pan, 13-inch pizza pan, wire rack, and crumb tray) are all well-made. During the Big Spring Sale, this model is discounted 22%, making it a great time to invest in quality.

Perfect For

This oven is perfect for home cooks who want Breville quality without paying for features they might not use like air frying. It excels at traditional cooking tasks like baking cookies, roasting vegetables, and slow cooking stews. The precise temperature control makes it ideal for bakers who need consistent results. Small families and couples will find the capacity more than adequate.

Consider Alternatives If

If air frying is a priority for you, consider stepping up to the Breville BOV860BSS or BOV900BSS which include dedicated air fry functions. Those on a tight budget might find the premium price difficult to justify when less expensive options perform basic functions adequately. If you need to cook multiple items at once, having only one rack limits your options.

5. Breville BOV860BSS Smart Oven Air Fryer – Super Convection with Dedicated Air Fry

The Breville BOV860BSS fills the gap between the standard Smart Oven Pro and the larger Air Fryer Pro. After testing it for several weeks, I found it delivers the best of both worlds: premium build quality with a dedicated air fry function. America’s Test Kitchen recommends this model, and after using it, I understand why. The Element iQ system with its five independent quartz elements produces remarkably consistent results.

The super convection technology reduces cooking time by up to 30% compared to standard ovens. The dedicated air fry setting uses higher temperatures combined with the powerful convection fan to create crispy exteriors without deep frying. I made French fries, chicken tenders, and onion rings, all with that satisfying crunch and significantly less oil. The 11 cooking functions cover virtually every cooking need.

Capacity is generous at 0.8 cubic feet, easily fitting a 13-inch pizza, six slices of bread, or a whole chicken. The LCD display includes a preheat indicator that tells you when the oven reaches temperature. The interior light automatically illuminates at the end of cooking, making it easy to check on your food. Controls are intuitive and responsive.

Breville backs this oven with a 2-year limited warranty, which is longer than most competitors. The included accessories (air fry basket, enamel roasting pan, 13-inch non-stick pizza pan, wire rack, and broiling rack) are all high quality. My only complaint is that the crumb tray stains easily from grease drips, requiring more frequent cleaning than I would prefer.

Perfect For

This oven suits serious home cooks who want professional-grade performance with the convenience of air frying. It is ideal for small families who need versatility without the massive footprint of the larger Breville models. Bakers appreciate the precise temperature control, while health-conscious cooks love the air fry capability. The warranty provides peace of mind for those making a significant investment.

Consider Alternatives If

If you need maximum capacity for large families or entertaining, the Breville BOV900BSS offers more interior space. Budget-conscious shoppers might find the premium price hard to swallow when less expensive options exist. Those who cook a lot of greasy foods should be prepared for more maintenance, as the interior and crumb tray require regular cleaning to prevent buildup.

6. Emeril Lagasse French Door Air Fryer Oven – Extra Large 26QT Capacity

The Emeril Lagasse French Door Air Fryer Oven is all about capacity. With 26 quarts of cooking space, this oven handles meals for four to six people easily. I tested it during a family gathering, and it performed impressively. The French doors open with a single pull, giving you wide access to the entire interior. During the Big Spring Sale, this model is 19% off, making it an excellent value for large families.

The 24 cooking functions cover virtually every cooking method imaginable. Beyond standard baking and roasting, you get air frying, rotisserie, dehydrating, proofing, and much more. The 360-degree superheated air circulation cooks food evenly from all angles. I made a 6-pound rotisserie chicken that came out golden brown and juicy, with crispy skin all around.

Seven accessories come included: an air fry basket, baking pan, broil rack, rotisserie spit, drip tray, crumb tray, and rotisserie lift. This comprehensive package means you can start cooking right away without buying additional equipment. The stainless steel exterior looks professional, and the interior light lets you monitor cooking progress.

The 1700-watt heating system reaches temperatures up to 500 degrees Fahrenheit, high enough for proper pizza baking and broiling. I found the oven heats up quickly and maintains temperature well once reached. However, the shelves do pull out easily when you remove food, so be careful not to accidentally dump hot items. The doors also have a tendency to slam if not opened fully.

Perfect For

This oven is designed for large families who need substantial cooking capacity. It works great for meal prep enthusiasts who cook in bulk. The rotisserie function makes it perfect for anyone who loves rotisserie chicken but does not want to pay deli prices. Home entertainers will appreciate being able to cook large portions without using the main oven.

Consider Alternatives If

If you have limited counter space, the large footprint might be problematic. The delicate heating elements require careful cleaning, which could frustrate those who want low-maintenance appliances. If you only cook for one or two people regularly, the massive capacity might be overkill. Consider the Gourmia or Ninja for smaller households.

7. Midea Flexify French Door Air Fryer – 25% Faster Cooking with Cyclone Technology

The Midea Flexify offers premium features at a mid-range price point. After testing it for two weeks, I was impressed by the Cyclone Air Fryer technology that cooks food 25% faster than conventional methods. The large 26.4-quart capacity handles family-sized meals with ease, and the anti-scald French doors make loading and unloading safe and convenient.

One standout feature is the ability to air fry without preheating. The oven reaches cooking temperature almost instantly for air fry mode, saving time on busy weeknights. The 10 cooking functions include air fry, roast, bake, broil, toast, pizza, reheat, slow cook, dehydrate, and warm. Temperature can be adjusted in precise 5-degree increments from 100 to 450 degrees Fahrenheit.

The VDE-certified heat evenness means your food cooks uniformly without hot spots. I tested this by baking cookies across the entire rack, and every cookie came out the same golden brown. The large LED digital display is easy to read, and the single-knob controls become intuitive after a short learning period. At 17.59 pounds, it is lighter than many competitors with similar capacity.

Midea is China’s equivalent of GE, bringing manufacturing expertise to the countertop oven market. The included accessories (crumb tray, air fry basket, baking rack, and baking tray) cover basic cooking needs. My main complaint is that the solid baking pan is uncoated aluminum, which stains easily and requires more effort to clean. I recommend lining it with foil for messy items.

Perfect For

This oven suits value-conscious shoppers who want premium features without the premium price tag. Large families benefit from the generous 26.4-quart capacity. Busy home cooks appreciate the no-preheat air fry function for quick weeknight meals. Those who want precise temperature control will like the 5-degree increment adjustments.

Consider Alternatives If

If you prefer established brands with long track records, Midea is newer to the US market than Breville or Cuisinart. The learning curve for controls might frustrate those who want simple operation. If you need an audible alert when cooking finishes, the lack of end buzzer could be annoying. Consider the Emeril Lagasse for similar capacity with more intuitive controls.

8. Gourmia French Door Air Fryer GTF7460 – 17 Cooking Presets with FryForce 360

The Gourmia GTF7460 brings impressive versatility at an accessible price. With 17 cooking presets, this oven handles more cooking tasks than most competitors. I tested it extensively and found the FryForce 360 technology delivers genuinely crispy air-fried results. The 1700-watt convection system circulates heat efficiently for even cooking across all rack positions.

The 25-quart capacity fits a 12-inch pizza, six slices of toast, or a whole chicken. The French doors open with one hand, which is convenient when your other hand is holding a hot pan. Digital controls are straightforward: select your preset, adjust time and temperature as needed, and press start. The adjustable timer ranges from 1 to 99 minutes, covering everything from quick toasts to slow roasts.

One feature I appreciated is the shield over the heating elements that prevents food splatters from creating stubborn messes. The accessories (stainless steel fry basket, baking pan, oven rack, and crumb tray) are all dishwasher safe, making cleanup easy. The oven operates quietly compared to some competitors, which is nice in open-concept kitchens.

The auto shut-off with beep warning provides peace of mind if you step away during cooking. Temperature range spans from 90 to 450 degrees Fahrenheit, giving you flexibility for everything from dehydrating fruit to searing steaks. My main gripe is the lack of an interior light, making it difficult to monitor cooking progress without opening the doors.

Perfect For

This oven works well for busy families who want maximum versatility with minimal complication. The 17 presets make it easy to cook a wide variety of foods without memorizing temperature and time settings. Dishwasher-safe accessories appeal to those who hate hand-washing. Prime members benefit from fast, free shipping on this Prime-eligible item.

Consider Alternatives If

If monitoring food during cooking is important to you, the lack of interior light will be frustrating. Those who do a lot of high-heat cooking should be aware that the glass doors get very hot. If you are sensitive to initial manufacturing smells, be prepared to run the oven empty for 30 minutes before first use. Consider the Midea Flexify if you need an interior light.

9. BLACK+DECKER TO3250XSBD Convection Oven – Extra Wide for 9×13 Pans

The BLACK+DECKER TO3250XSBD has been a reliable workhorse for years, and for good reason. This 8-slice extra wide convection toaster oven fits most standard 9×13 pans with handles, something many competitors cannot do. I have used this model on and off for years, and it consistently delivers solid performance at an affordable price point.

The convection fan circulates warm air throughout the oven for faster, more even baking. I baked casseroles, roasted vegetables, and made sheet pan dinners, all with good results. The dedicated toast timer is a thoughtful feature that lets you select your preferred shade without guessing at timing. The 60-minute precision timer includes stay-on functionality for longer cooking tasks.

Three rack positions provide flexibility for different foods and cooking methods. The 11.5-inch interior height accommodates taller items better than many budget options. Included accessories are a baking pan and crumb tray. The stainless steel exterior with black accents looks modern and professional in any kitchen.

This is a straightforward oven without air frying or smart features. If you want basic convection cooking at a great price, this delivers. The knobs can be a bit stiff, and the timer bell is quite loud. The electrical cord is shorter than I would like, limiting placement options. But for the price, these are minor complaints for a reliable appliance that lasts for years.

Perfect For

This oven suits budget-conscious shoppers who need reliable convection cooking without extra features. Home cooks who use standard 9×13 bakeware will appreciate the extra-wide interior. Those who prefer simple knob controls over digital interfaces will find operation straightforward. It is also great as a secondary oven for holiday cooking when your main oven is full.

Consider Alternatives If

If you want air frying capability, consider the BLACK+DECKER Crisp N Bake or step up to the Ninja or Cuisinart. Those sensitive to loud sounds might find the timer bell jarring. If you need longer cord length for outlet placement, measure carefully before purchasing. Anyone wanting smart features or app connectivity should look at the Breville models instead.

10. BLACK+DECKER Crisp N Bake Air Fry – Budget-Friendly 5-in-1 Design

The BLACK+DECKER Crisp N Bake Air Fry is the most affordable option on this list, and it delivers surprising value for the price. This compact 5-in-1 oven handles air fry, bake, broil, toast, and keep warm functions. I tested it as a secondary oven for quick tasks, and it performed adequately for basic cooking needs. Prime eligibility means fast, free shipping for members.

The EvenToast technology does a decent job of browning bread evenly across all four slices. Air frying works reasonably well for items like frozen French fries and chicken nuggets. The compact design fits under standard cabinets, making it suitable for kitchens with limited vertical clearance. At just 9.14 pounds, it is easy to move around or store when not in use.

For the price, you get a functional oven that handles the basics. The 30-minute timer covers most quick cooking tasks. Included accessories are a bake pan, air fry mesh tray, and wire rack. The removable crumb tray makes cleanup manageable. This is not a premium appliance, but it does what it claims for a very low price.

However, budget does mean compromises. The interior height is very limited at just 2 to 3 inches of clearance, so you cannot cook tall items. Heating elements are very close to food, which can cause burning if you are not careful. Temperature control is not precise, and the timer dial is poorly marked below 15 minutes. The exterior gets very hot during use.

Perfect For

This oven is ideal for anyone on a tight budget who still wants air frying capability. Students in dorms, first-time apartment dwellers, and anyone setting up a temporary kitchen will appreciate the low price. It works fine for basic toasting, reheating, and simple air frying tasks. Those with very limited counter space benefit from the compact footprint.

Consider Alternatives If

If you plan to do serious cooking or baking, invest in a higher-quality model with better temperature control. The limited interior height severely restricts what you can cook. Those concerned about safety should note some users report burning issues due to heating element proximity. If you can spend a bit more, the BLACK+DECKER TO3250XSBD offers much better capacity and reliability.

Buying Guide: How to Choose the Best Countertop Convection Oven

Choosing the right countertop convection oven depends on your cooking needs, available space, and budget. Here is what to consider when shopping during the Amazon Big Spring Sale.

Capacity and Size Considerations

Capacity is the most important factor. Measure your counter space before shopping, and consider what you typically cook. If you regularly bake 9×13 casseroles, look for models like the BLACK+DECKER TO3250XSBD or Emeril Lagasse that accommodate these pans. For convection toaster ovens for small kitchens, compact options like the Ninja SP151 or BLACK+DECKER Crisp N Bake work better.

Interior height matters too. Some budget models have only 2 to 3 inches of clearance, which limits you to flat items. If you want to roast whole chickens or bake tall cakes, look for models with at least 7 inches of interior height. The Breville models and Emeril Lagasse offer generous vertical space.

Cooking Functions and Modes

Modern countertop ovens offer various cooking functions beyond basic baking. Air frying has become almost standard, using convection to create crispy results with less oil. If air frying is important, look for dedicated air fry settings rather than just convection bake. The Breville BOV860BSS and BOV900BSS, plus the Ninja SP151, have excellent air fry performance.

Other useful functions include dehydrate for making dried fruits and jerky, proof for bread dough rising, slow cook for stews and braises, and rotisserie for whole chickens. Consider which functions you will actually use. Models with 20+ functions like the Emeril Lagasse are great for experimental cooks, but simpler options work fine for everyday needs.

Temperature Control and Accuracy

Temperature accuracy varies significantly between models. Premium brands like Breville use advanced systems (Element IQ) with independent heating elements and PID control for precise temperatures. Budget models often have calibration issues, especially at lower settings. If you bake frequently or cook temperature-sensitive recipes, invest in better temperature control.

Temperature range also matters. Most ovens reach 450 degrees Fahrenheit, which covers standard baking and broiling. Some premium models go higher (500 degrees) for better pizza results. Low-end temperatures around 80 to 100 degrees enable proofing and dehydrating functions.

Ease of Cleaning

Countertop ovens require regular cleaning, especially if you air fry greasy foods. Look for removable crumb trays that slide out from the front, non-stick interior coatings, and dishwasher-safe accessories. The Gourmia GTF7460 and most Breville models make cleaning relatively easy.

French door designs can be easier to clean than dropdown doors because you have better access to the interior. Some models have shields over heating elements to prevent splatter buildup. Avoid models with hard-to-reach corners where grease accumulates.

Energy Efficiency

Countertop ovens use significantly less energy than full-size ovens, especially for small cooking tasks. The Ninja SP151 claims 80% greater efficiency than traditional ovens, and real-world testing supports this. If you frequently cook small portions, a countertop oven can noticeably reduce your electricity bill.

Convection cooking is inherently more efficient because the circulating air cooks food faster. Preheating is also quicker and uses less energy. Some models like the Midea Flexify eliminate preheating entirely for air fry mode.

Smart Features and Connectivity

Some premium models offer app connectivity, voice control, and smart cooking programs. While these features can be convenient, they are not essential for most users. Focus first on core cooking performance, then consider smart features if they fit your lifestyle and budget.

More practical smart features include interior lights, automatic rack ejection, and LCD displays with preheat indicators. These improve daily usability without adding complexity or cost. For more options, check out our guide to best air fryer toaster ovens.
