The Dash Mini DMTO100 is the smallest toaster oven in RTINGS’ tested group, but it holds only one slice of bread and has very basic functions. If you need an oven for baking or more than a single serving, compare compact alternatives by both their counter footprint and the food their chambers can actually fit. The Breville Mini Smart Oven suits baking-focused use; the Ninja Flip SP151 adds air-fry capability and can be stored upright, but its chamber is low.
How to choose the smallest toaster oven that still works for you
“Smallest” can mean the least counter space or the smallest appliance that remains useful beyond toast. Decide which matters more before comparing models. RTINGS’ guide, updated September 10, 2026, says it tested more than 25 models; its smallest tested option is the Dash Mini, but that size comes with a one-slice limit.
Measure the space where the oven will sit, including the manufacturer’s required clearance. Then match the interior to the food you make: count bread slices, check pizza diameter, and consider whether a pan or loaf needs more chamber height. A low-profile oven can save room while ruling out taller cookware.
- For minimal footprint and toast: consider the Dash Mini.
- For baking controls and a taller chamber: consider the Breville Mini Smart Oven.
- For versatile cooking and upright storage: consider the Ninja Flip, if its low chamber suits your cookware.
- For basic four-slice use: compare the Panasonic FlashXpress and Black+Decker Natural Convection.
Compact toaster ovens at a glance
| Model | Capacity and shape | Functions and trade-offs |
|---|---|---|
| Dash Mini DMTO100 | One slice of bread; RTINGS identifies it as the smallest model in its tested set. | Basic functions; no temperature control, broil mode, or air-fry fan. Small chamber can be awkward to clean. |
| Breville Mini Smart Oven BOV450XL | Four slices; taller chamber with three rack positions. Breville’s pages conflict on pizza capacity: one says 11 inches, another says 9 inches. | Eight functions and 1800 watts. No convection fan or air fry, according to RTINGS. |
| Ninja Flip SP151 | Fits an 11-inch frozen pizza or six slices of sandwich bread; low chamber may not fit a loaf pan. Flips upright for storage. | Bakes and air-fries, though RTINGS says it does not match a good basket-style air fryer. |
| Panasonic FlashXpress NB-G110P | Four slices or a 9-inch pizza; smaller on the counter than the Breville Mini, according to RTINGS. One rack position. | No fan or broil function. |
| Black+Decker Natural Convection 4-Slice TO1756SB | Four slices or a 9-inch pizza; occupies more counter area than the Panasonic, according to RTINGS. | Budget-oriented basic model. |
| Oster Compact Air Fryer Oven | 18 quarts/17 liters; space for a whole chicken or a 9-inch pizza. Exterior dimensions are not stated on the cited product page. | Five functions and three rack positions; larger capacity prioritizes cooking room over a verified small footprint. |
Best for the absolute minimum footprint: Dash Mini DMTO100
Choose the Dash Mini if counter space is the overriding concern and your main job is making a single slice of toast. RTINGS calls it the smallest toaster oven in its tested selection. Its compact chamber is not a practical substitute for a general-purpose oven: it lacks temperature control, broil, and an air-frying fan, and the small interior can be awkward to clean.
#1 Best Overall
- COMPACT & SPACE SAVING: Versatile compact design fits nicely in small spaces when counter space is limited.
- ADJUSTABLE TIMER: The 15 min timer is perfect for toasting and warming up food for a quick and easy snack or breakfast.
- ADJUSTABLE TEMPERATURE CONTROLS: Adjust your oven controls between 200F-450F degrees for toasting, warming or baking.
- 650 WATTS OF POWER: Built-in temperature thermostat maintains even cooking heat to keep food warm, bake or toast.
- ACCESSORIES INCLUDED - Includes a non-stick back pan and wire rack that easily slides in and out of the rack position to suit a variety of foods.
Before buying, consider whether one slice at a time fits your routine. If you regularly heat leftovers, bake, or prepare food for more than one person, a somewhat larger model is likely to be more useful.
Best compact option for baking: Breville Mini Smart Oven BOV450XL
The Breville Mini offers a taller chamber and three rack positions, making it a better fit than ultra-small designs when baking is important. Breville lists four-slice capacity, eight functions—Bagel, Toast, Bake, Broil, Pizza, Roast, Cookies, and Reheat—and 1800 watts. RTINGS describes its baking performance as good, but notes that it has no convection fan or air-fry feature.
Rank #2
- ACCOMMODATES 9-INCH PIZZA OR 4 SLICES OF BREAD – Designed to maximize utility within a compact footprint, the curved interior fits a 9-inch pizza or 4 slices of bread. Place items evenly for best results when toasting, baking, or reheating.
- FOUR VERSATILE COOKING FUNCTIONS – Select from baking, broiling, toasting, or keeping food warm. Natural convection airflow circulates heat throughout the oven—preheat for 10 minutes to ensure consistent cooking and crisp results.
- PRECISION 30-MINUTE TIMER WITH STAY-ON OPTION – The 30-minute timer includes clearly marked toast settings and a stay-on function. Oven will not operate unless timer is set or stay-on is selected, ensuring controlled and safe operation.
- CONVENIENT REMOVABLE CRUMB TRAY – The slide-out crumb tray allows for quick, hygienic cleanup. To prevent spills and overheating, keep food and bakeware at least 1½ inches from the top heating elements and fully contained within the tray.
- COMPACT AND CONTEMPORARY DESIGN – Measuring 14.5" x 10.8" x 8.8", this sleek stainless steel toaster oven complements any kitchen. Outer surfaces become hot during use—always use oven mitts and allow space for proper ventilation.
Breville’s U.S. product information gives approximate exterior dimensions of 15.5 inches wide by 13 inches deep by 8.75 inches tall and recommends four inches of clearance behind and above the oven. Its official pages disagree about pizza capacity: one lists an 11-inch pizza, while another says a 9-inch pizza. Do not rely on either figure without checking the current documentation for the exact BOV450XL model.
Best for upright storage and added versatility: Ninja Flip SP151
The Ninja Flip is a space-saving choice in a different sense: after cooking, it can be flipped upright to free counter space. RTINGS names it the best small toaster oven in its comparison. It fits an 11-inch frozen pizza or six slices of sandwich bread, and it bakes and handles some air frying.
Rank #3
- 5-IN–1 MULTIFUNCTIONAL COOKING- Enjoy versatile cooking with Air Fry, Bake, Broil, Toast, and Keep Warm settings. Perfect for preparing a wide variety of meals from crispy fries to perfectly baked pizzas and golden toast.
- HEALTHY AIR FRYING TECHNOLOGY – Cook crispy, delicious meals with little to no oil using advanced air frying technology. Enjoy healthier alternatives to your favorite fried foods without compromising taste or texture.
- EVENTOAST TECHNOLOGY FOR PERFECT TOAST – Achieve evenly toasted bread, bagels, and more with BLACK+DECKER’s EvenToast technology, ensuring consistent results every time with no hot spots.
- COMPACT YET SPACIOUS INTERIOR – Fits up to a 9-inch pizza or 4 slices of bread, making it ideal for quick family meals, snacks, or small batch cooking while saving valuable counter space.
- USER-FRIENDLY CONTROLS & 7 ACCESSORIES – 30-minute timer with removable crumb/drip tray, bake pan, air fry mesh tray, and wire rack for easy cleanup. Use drip tray when cooking and keep food clear of heating element. See User Manual for proper use.
The trade-off is chamber height. The low interior may not fit a loaf pan, so check the height of your cookware rather than relying on the exterior profile. RTINGS also cautions that its air frying does not match the performance of a good basket-style air fryer.
Other compact alternatives for simple cooking
Panasonic FlashXpress NB-G110P
RTINGS describes the FlashXpress as smaller on the counter than the Breville Mini, with room for four slices or a 9-inch pizza. It has one rack position and lacks both a fan and broil function, so it is best considered for straightforward cooking rather than broader oven-style versatility.
Rank #4
- AIR FRY TECHNOLOGY: Enjoy deep-fried taste without the fat. High-intensity hot air circulates to crisp fries, chicken, and snacks with little to no oil.
- MAX SPACE DESIGN: 20% more air frying capacity* while keeping the same countertop footprint. Fits most 9” round pans, up to 4 slices of toast, or a 10” pizza.
- 5 VERSATILE COOKING FUNCTIONS: Prepare a variety of meals with Air Fry, Bake, Broil, Toast, and Warm settings for everyday cooking convenience.
- SIMPLE DIAL CONTROLS: Easy-to-use knobs adjust temperature, cooking time, and toast browning levels for quick, intuitive operation.
- ACCESSORIES INCLUDED: PFAS-free ceramic-coated baking pan (8x more durable), air fry basket, wire rack, and removable crumb tray for easy cooking and cleanup.
Black+Decker Natural Convection 4-Slice TO1756SB
This budget-oriented basic model fits four slices or a 9-inch pizza, according to RTINGS. It takes up more counter area than the Panasonic FlashXpress, so compare the available space as well as the matching slice and pizza capacities.

The Oster Compact Air Fryer Oven is a different compromise, not a verified smallest-footprint pick. Oster specifies a capacity of 18 quarts/17 liters, room for a whole chicken or a 9-inch pizza, three rack positions, and five functions: air fry, bake, broil, toast, and warm. The cited product page does not give exterior dimensions, so its relative counter footprint cannot be established from that information. Consider it if air frying and larger food capacity matter more than minimizing the appliance’s size.

Measure before you buy
- Measure the counter space. Record available width, depth, and height at the intended location.
- Allow for clearance. For the Breville Mini, Breville recommends four inches behind and above; consult the exact model’s current instructions for any appliance you are considering.
- Check the foods and pans you use. Compare slice count, pizza diameter, and cookware height with the stated capacity. A fit for a flat pizza does not establish that a loaf pan will fit.
- Choose functions based on actual tasks. Check whether you need bake, broil, convection, or air fry, rather than treating a longer feature list as automatically better.
- Recheck the exact model details. Product specifications and availability can change, and the Breville pages cited here conflict on pizza size.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
