The standard toaster oven sits squarely on your countertop, consuming precious real estate and often blocking the backsplash. An under counter toaster oven changes that equation entirely, mounting beneath cabinets to reclaim bench space while keeping toast, roast, and air fry capabilities within arm’s reach. The decision to switch from a freestanding model to an under-counter unit isn’t just about size—it’s about installation clearance, heat management, and door swing geometry that a standard appliance never requires you to consider.
I’m Mohammad Maruf — the founder and writer behind AirfryerBite. I’ve spent years analyzing kitchen appliance specifications, comparing convection fan speeds, interior volumes, and heating element configurations to help readers make informed decisions about compact cooking hardware.
The challenge with mounting a toaster oven under cabinets is that most models are designed for countertop placement, leaving buyers to guess whether a 16.5-inch depth will leave enough room for ventilation and door operation. This guide breaks down the critical dimensions, heat management requirements, and performance specs you need to find the best under counter toaster oven that actually fits your space.
How To Choose The Best Under Counter Toaster Oven
Selecting a toaster oven for under-counter installation requires more than just comparing cooking presets. You must account for the physical constraints of your cabinet cutout, the heat output during operation, and how the door will function when installed at countertop height. These five factors are the non-negotiables for any under-counter setup.
Critical Height Clearance and Ventilation
Measure the vertical distance between your countertop and the bottom of your upper cabinet. Most toaster ovens require at least four inches of clearance above the unit for proper airflow to prevent overheating the cabinet above. Some French-door models vent from the front or sides, which can reduce the required overhead space. Check the manufacturer’s specified clearance before purchasing; blocking the exhaust vents can shorten the oven’s lifespan and create a fire risk.
Door Swing: French Door vs. Dropdown
A dropdown door requires the oven to be pulled forward enough that the door can fully open without hitting the lower cabinets. French door models, like the Gourmia or Oster, open outward from the center and typically need less forward extension, making them a superior choice for tight counter depths. If you’re mounting the oven directly under a cabinet with little front clearance, prioritize a French door design.
Depth and Footprint Fit
The depth of the oven from front to back determines whether it will fit flush under your cabinet or overhang the counter. A depth of 16 to 17 inches is common for larger units, but your countertop depth (usually 24 to 25 inches) must accommodate both the oven body and the cord clearance at the back. Allow at least one to two inches of open space behind the unit for the power cord and back-panel ventilation.
Convection Fan and Heat Distribution
For an under-counter unit, a quiet, efficient convection fan is important because the oven runs closer to your workspace and living area. A high-RPM fan (2000 RPM or above) reduces hot spots and cooks food faster, which also means the oven runs for shorter periods—helpful for managing heat buildup in a confined space. Look for models with at least 1500 watts of power to maintain consistent cooking temperatures.
Safety Features: Auto Shutoff and Cool-Touch Exterior
Since the oven will be installed at countertop height near cabinets and possibly within reach of children, an auto-shutoff timer and a cool-touch door are essential. Models with double-layer glass or insulated doors minimize the risk of burns. A programmable timer that automatically cuts power when the cooking cycle ends is a basic but crucial safety feature for any under-counter installation.

In‑Depth Reviews
1. Gourmia French Door Air Fryer Oven – 37 Qt
This Gourmia unit checks the most important box for under-counter installation: its French door design requires minimal forward clearance to open, making it one of the few large ovens that can sit closer to cabinet fronts without obstruction. The 37-quart interior fits a 13-inch pizza, full sheet pan, or up to nine slices of toast, giving you near full-oven capacity in a package measuring 16.5 inches deep. FryForce 360° technology circulates hot air at high velocity, and the 1700-watt heating element reaches up to 450°F for proper searing and crisping.
The 12 cooking presets cover air fry, bake, toast, broil, dehydrate, slow cook, and proof, reducing the guesswork for common dishes. Owners note that the exterior gets hot during operation—something to factor into your under-counter clearance plan—but the included accessories (air fry basket, baking pan, oven rack, and crumb tray) are all dishwasher safe for easy cleanup. The knob control interface is straightforward and responsive, and the digital display shows cook time and temperature clearly.
For an under-counter setup, the combination of French doors, generous capacity, and solid 1700-watt output makes this the strongest all-around choice. The 90°F minimum temperature also supports proofing and dehydrating, adding versatility beyond standard toaster oven functions. Just ensure you maintain the recommended four-inch overhead clearance for safe ventilation.
Why it’s great
- French doors open with minimal forward clearance
- 37-quart capacity fits sheet pans and 13-inch pizzas
- 12 presets including slow cook and proof
- All accessories dishwasher safe
Good to know
- Exterior gets hot during operation
- Requires four inches overhead for proper ventilation
- No internal light for checking food
2. Oster Extra-Large 42L French Door Toaster Oven
The Oster 42L is the largest French door toaster oven in this lineup, purpose-built for household cooking that requires accommodating 15×12 baking pans or two large pizzas simultaneously. Its 42-liter capacity translates to roughly 44 quarts, giving it more usable vertical space than the Gourmia, though its depth of 20.51 inches demands careful measurement of your countertop before attempting under-counter installation. The magnetized door assist keeps the French doors open while you load food, a small ergonomic detail that matters when you’re working in a confined space.
Six cooking presets (Bake, Toast, Broil, Warm, Air Fry, and Turbo Convection) cover the essentials without overwhelming the user, and the separate knob controls for function, time, and temperature make operation intuitive. The Turbo Convection setting uses a fan to circulate heat, reducing cooking times compared to standard radiant ovens. Owners report consistent results for roasting chickens and baking casseroles, with the wire rack, baking pan, and crumb tray included out of the box.
The primary limitation for under-counter use is the 20.5-inch depth—most standard countertops are 24 to 25 inches deep, leaving only 3.5 to 4.5 inches for back clearance and cord management. If your countertop depth is at least 24 inches, this unit fits, but a shallower counter will create overhang. No interior light is included, which some users find inconvenient when checking food inside a dark cavity.
Why it’s great
- Extreme 42-liter capacity fits large pans and two pizzas
- Magnetized French door assist for easy loading
- Turbo Convection for faster, even cooking
- Simple knob controls for each cooking parameter
Good to know
- 20.5-inch depth requires a full 24-inch countertop
- No interior light for food monitoring

3. Typhur Sync Oven with Smart AI Wireless Probe
The Typhur Sync Oven brings a level of precision normally reserved for dedicated smokers and sous vide setups. Its built-in wireless meat probe tracks core temperature in real time and automatically stops the cook at your target doneness, removing the need for constant supervision. The 2400 RPM turbo convection fan is the fastest in this comparison, distributing heat evenly across the 27-quart cavity and producing crispier air fry results than units with slower fans. The oven measures 16.7 inches deep, making it one of the most under-counter-friendly premium options.
Twelve cooking modes range from Roast and Broil to Proof and Dehydrate, with a temperature window of 85°F to 450°F. The Typhur app adds remote control, recipe guidance, and AI recipe generation from a photo of ingredients—a novelty that some users appreciate for inspiration. The magnetic probe dock stores and wirelessly charges the thermometer, so it’s always ready. RTINGS ranked this the best toaster oven tested, citing fast preheat and stable temperature performance.
For under-counter installation, the 16.7-inch depth is manageable, but the dropdown door requires the oven to be pulled forward enough to clear the cabinet above. The interior is large enough for a 12-inch pizza, 6-pound chicken, or 2 pounds of fries, though the 27-quart capacity is smaller than the Gourmia or Oster. Some parts are dishwasher safe, but the probe case and certain accessories require hand washing.
Why it’s great
- Built-in wireless probe with auto-stop at target doneness
- 2400 RPM convection fan for superior heat distribution
- App control and AI recipe generation
- Compact 16.7-inch depth fits most countertops
Good to know

4. Nuwave Combi Steam Oven
The Nuwave Combi Steam Oven breaks from the standard toaster oven formula by adding adjustable steam infusion to its convection cooking capabilities. The COMBO mode simultaneously steams the interior of proteins while air frying the exterior, producing juicy meats with a crisp crust. Temperature control spans from 50°F to 450°F in one-degree increments, combined with moisture settings ranging from 10% to 90%, giving you fine-grained environmental control inside the 16-quart cavity. The stainless steel interior has no nonstick coating, which appeals to buyers avoiding PTFE and PFOA.
With 120 presets built in, the Nuwave reduces the trial-and-error phase for common foods like chicken, vegetables, and bread. The sous vide function operates at low temperatures without needing water baths or bags, saving counter space. The oven measures 14.75 inches deep, making it one of the most compact options for under-counter installation. The removable drip tray and water tank are dishwasher safe, simplifying cleanup after steam cooking.
The tradeoffs are the 16-quart capacity, which is small—it toasts 4 slices and fits a 5-pound chicken, but not a full sheet pan or large pizza. The touch control interface is sensitive, and the water tank must be filled from the bottom, which some users find awkward. For those who want steam-enabled versatility in a small under-counter footprint, this unit delivers unique functionality.
Why it’s great
- Adjustable steam infusion for moist interiors and crispy exteriors
- 120 presets reduce cooking guesswork
- Compact 14.75-inch depth ideal for tight spaces

- Water tank design requires bottom filling
5. Cuisinart TOB-135 Deluxe Convection Toaster Oven
The Cuisinart TOB-135 has been a staple in the countertop oven category for years, and its 0.6 cubic-foot capacity (roughly 18 quarts) makes it a natural fit for under-counter applications where every inch of space is measured twice before purchase. At 15.3 inches deep and 9.3 inches tall, it’s short enough to slide under most cabinets without requiring extensive clearance planning. The digital controls feature a blue backlit display with an electronic dial and LED buttons, giving it a modern interface without touchscreen fragility.
Nine cooking functions include convection bake, broil, toast, and keep warm, with a convection fan that reduces cooking times by circulating hot air across the cavity. The nonstick interior simplifies cleanup, and the slide-out crumb tray catches drips and crumbs effectively. The preheat-ready signal and automatic shutoff are standard safety features that become more important when the unit is installed in a confined under-counter space. It fits six slices of toast or a 12-inch pizza comfortably.
The dropdown door is the main consideration for under-counter mounting—you’ll need to pull the oven forward enough for the door to clear the cabinet. The brushed stainless steel finish matches most kitchen appliances, and the build quality meets Cuisinart’s typical reliability standards. Some users note that the convection fan is louder than expected, but the even browning and consistent temperature make it a proven performer.
Why it’s great
- Compact 15.3-inch depth fits under most cabinets
- Digital display with intuitive knob controls
- Nonstick interior and removable crumb tray for easy cleaning
- Reliable Cuisinart build quality

6. Cuisinart CSO-300N Convection Steam Oven
The Cuisinart CSO-300N is a dedicated convection steam oven, distinct from standard toaster ovens because it injects moisture into the cavity during cooking. The 120-minute uninterrupted steam cycle is useful for bread proofing, steaming vegetables, and baking with a crisp crust and moist interior. The 0.6 cubic-foot cavity fits a 4.5-pound chicken or a 12-inch pizza, and the 47-ounce removable water reservoir sits on the front for easy refills. The dropdown door uses a gasket seal to contain steam, which also helps maintain consistent internal humidity.
For under-counter installation, the 15.5-inch depth is manageable, but you must factor in the water reservoir’s position and the need to pull the oven forward to open the dropdown door. The steam function cooks up to 40% faster than conventional ovens, reducing the time heat builds up around the cabinet. The interior has no nonstick coating, relying entirely on stainless steel, which eliminates PTFE and PFOA concerns entirely.
Customer feedback highlights a learning curve: recipes designed for standard ovens need adjustment for steam-assisted cooking. The plastic water container has a flimsy handle and requires filling from the bottom, which is less convenient than top-fill designs. Some units have developed leaks over time, damaging the countertop below, so a drip tray or protective mat is advisable for under-counter setups.
Why it’s great
- 120-minute steam cycle for baking and proofing
- No nonstick coating; stainless steel interior
- Cooks up to 40% faster than conventional ovens
- Gasketed door contains steam effectively
Good to know
- Water container requires bottom filling
- Learning curve for steam-based recipes
- Some units reported leaking over time
7. Café Couture Oven with 14 Cooking Modes
The Café Couture Oven brings smart home connectivity to the countertop oven segment with Wi-Fi control via the SmartHQ app and voice commands through Echo or Google Home devices. Its 25-liter capacity (approximately 26 quarts) accommodates 12-inch pizzas, 9×13 cake pans, and 2-quart casserole dishes. Six total heating elements enable rapid preheating and even heat distribution across the cavity, with a temperature range from 80°F for proofing to 450°F for air frying. The matte black finish adds a design-focused aesthetic that stands out from the standard stainless steel crowd.
Fourteen cooking modes including Air Fry, CrispFinish, Bake, Broil, Toast, Bagel, Pizza, Cookies, Proof, Dehydrate, Slow Cook, Reheat, and Keep Warm cover virtually any home cooking task. The CrispFinish feature adds a final burst of high heat to brown foods without overcooking the interior. At 28 pounds, this is one of the heaviest units, and its 17-inch depth requires careful countertop measurement before under-counter installation.
The dropdown door design means you need to account for swing clearance below the cabinet. The included accessories—heavy-duty wire rack, baking tray, pizza pan, air fry basket, and crumb tray—offer a complete setup out of the box. Some users find the app integration useful for remote monitoring, but the physical knob controls and LCD display are sufficient for most daily use without the app.
Why it’s great
- Wi-Fi and voice control for remote operation
- Six heating elements for quick preheat and even cooking
- 14 cooking modes with CrispFinish feature
- Matte black design for modern kitchens
Good to know
- 17-inch depth requires careful measurement

- Heavy at 28 pounds; not easily moved
8. Empava 24 inch Electric Single Wall Oven
The Empava 24-inch wall oven is a true built-in unit designed for permanent cabinet installation, not countertop sitting. Its 2.3 cubic-foot capacity dwarfs every other oven on this list, and the convection system, broil element, and halogen interior light match the specs of a full-size range oven. The mechanical knob controls include a built-in timer and temperature settings up to 480°F, providing precise cooking control without relying on digital touchscreens. The brushed stainless steel finish and ergonomic handle integrate into a standard 24-inch cabinet cutout.
For under-counter installation, this is the only product here that expects to be built into a dedicated slot—it requires professional installation and is not a plug-and-play countertop unit. The dropdown door includes a large window and halogen lighting for monitoring food without opening the door. The convection fan distributes hot air evenly, and the black ceramic interior provides a premium aesthetic while resisting stains. The 2-year US-based manufacturer’s warranty is double the standard for built-in ovens.
The tradeoffs are significant: this is a permanent appliance that requires wiring and cabinet modification. Customer reviews report inconsistent quality control, with some units failing within weeks and replacement units arriving damaged. The single rack is difficult to find replacements for, and the timer function is quiet and inconvenient. For buyers wanting a permanent under-counter oven solution, this unit offers the capacity but carries reliability risks.

The convection heating element uses top and bottom heating combined with a fan for even baking, while the microwave function handles quick reheating and defrosting. The soft-close door prevents slamming, and the double-layered glass keeps the exterior cool to the touch—a meaningful safety feature for under-counter placement near children. The touch control LCD display provides access to 14 cooking programs and an auto defrost function.
For under-counter installation, the KoolMore is designed as a built-in unit that fits standard 24-inch cabinet openings. The 1.5 cubic-foot capacity is generous for a microwave and adequate for the convection oven function, handling pizzas and casseroles. The reinforced door hinges support up to 66 pounds, allowing you to rest hot cookware on the open door temporarily. The stainless steel finish matches standard kitchen appliances, and the quiet operation is a step up from typical microwave noise levels.
The downsides include a maximum oven temperature of 400°F, which is lower than most dedicated toaster ovens and insufficient for recipes requiring 425°F or higher. Customer reports indicate the unit requires a dedicated 20-amp circuit, which may not be available in all kitchens. Some users experienced power failures and inconsistent performance within months of installation. For buyers who prioritize space savings and microwave convenience over maximum oven temperature, this combo unit fills a specific niche.
