You are asking one machine to reheat leftovers like a microwave, crisp wings like an air fryer, and bake a pizza like a convection oven. That is a lot from one countertop box. The trick is finding a combination microwave toaster oven that delivers on all three without burning the outside of your garlic bread or leaving the middle frozen.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The goal here is clear: find the best combination microwave toaster oven that fits your counter, your cooking style, and your budget — because a bad one just takes up space and frustrates you at dinner time.
Our Picks at a Glance
How To Choose The Best Combination Microwave Toaster Oven
Picking a combo oven depends on three major decisions: how big your kitchen is, what you cook most, and whether you prefer a countertop model or a built-in unit. Here is what really moves the needle.
Capacity and physical footprint
The internal capacity (measured in cubic feet) determines whether a 12-inch pizza fits or you are stuck microwaving small bowls. A 0.9 cu ft unit is fine for a dorm or RV, while 1.2 cu ft handles a whole casserole. But do not just check the interior — measure your counter depth and height. A 90-pound built-in like the AAOBOSI needs a 24-inch cabinet, not a standard countertop spot.
Wattage and cooking power
Microwave wattage (900W to 1000W is the balance for most homes) dictates how fast food heats. Convection wattage (typically 1400W to 1700W) controls how evenly the oven bakes and browns. Higher wattage usually means faster cooking, but also higher energy consumption.
Cooking modes that actually get used
Ignore the total number of presets for a moment. The three modes that matter most are: standard microwave for reheating, convection bake for cookies and chicken, and air fry for crispy foods with less oil. An oven that nails these three is worth more than one with 32 menus that no one remembers how to use.

In‑Depth Reviews
1. FRIGIDAIRE 1.2 cu ft Microwave, Digital Air Fryer, Convection Oven Combo
Our pick — over 4★ from 350+ verified ratings; the strongest balance of quality and price.
You get a 1.2 cubic foot interior — 33% more space than the BLACK+DECKER 0.9 cu ft model — so a whole pizza fits and a family casserole slides in.
The FRIGIDAIRE bakes evenly because it has a true 1500W convection element (a heating element with a fan that circulates hot air), so biscuits brown evenly instead of turning pale on one side. It also gives you 900W for microwaving and a 1000W oven heating element — three cooking powers in one box. The included air fryer plate and bake plate mean you do not need a separate gadget. Buyers report the unit is quiet in operation and the door stays locked safely when the button is pressed. The five one-touch menus (Potato, Popcorn, Beverage, Reheat, Frozen Dinner) handle common tasks fast, but the air fryer instructions are not the clearest; a few owners mention the manual leaves some guesswork for first-time use.
The recurring trade-off is reliability: a handful of units have stopped heating after a few weeks. Given the solid 4.2-star crowd backing, this still gives you the best mix of spacious interior and multi-function performance among the picks here.
Why it wins
- Biggest capacity in the mid-range class at 1.2 cu ft
- Separate 1500W convection for real baking results
- Includes both air fry kit and bake plate from the start
The honest trade-offs
- Air fryer instructions are vague; expect some trial and error
- Early durability issues reported by a small subset of owners
Reach for it if: you need the largest usable interior for family cooking and want a real convection oven, not just a fan — it beats the BLACK+DECKER on size and the Breville on value.
Look elsewhere if: you need the simplest out-of-the-box experience — the BLACK+DECKER is easier to figure out on day one.
2. BLACK+DECKER 5-in-1 Microwave Oven Air Fryer Combo, 0.9 Cu.Ft, 900W
Five cooking modes in a compact frame that fits small kitchens and RV counters while staying affordable — but the 0.9 cu ft interior is tight for a 12-inch pizza.
This BLACK+DECKER packs microwave, air fryer, bake, roast, and combi (grill/convection) into a 0.9 cu ft body that measures just 14.5 inches deep and 19.5 inches wide — small enough for tight counter spaces. The 900-watt output and 10 cooking levels handle everyday reheating and defrosting, while the 11 preset air fry menus take the guesswork out of frozen fries, chicken wings, and fish sticks. Buyers consistently say the 5-in-1 exceeds expectations, with even cooking and crispy air-fry results that use very little oil. The child-lock feature (press stop for 3 seconds) adds confidence.
The biggest durability concern: some units have died completely after 7 months. For the price, the value is undeniable for occasional use, but if you plan on heavy daily cooking across multiple modes, the sturdier FRIGIDAIRE or GE may justify the higher spend.
Where it shines
- Very compact footprint ideal for dorms, RVs, and small kitchens
- 11 air fry presets remove guesswork from frozen foods
- Easy-to-use touch controls and quiet operation
Limitations to know
- 0.9 cu ft interior is small; a 12-inch pizza barely fits
- Light weight causes the unit to slide when opening the door
- Long-term durability is a gamble based on owner reports
Pick this for: tight spaces and occasional multi-mode cooking where counter inches matter more than max capacity. The FRIGIDAIRE offers a bigger (1.2 cu ft) interior if you have the room.
skip it if: you need to cook full family meals daily — the FRIGIDAIRE gives you the extra room and stronger convection.
3. GE 4-in-1 Air Fry Countertop Microwave Oven, 1050 Watt, 1.0 Cu. Ft.
Five functions in a 1.0 cu ft frame, and the standout feature is genuinely quiet operation — owners confirm it is great for dorms, offices, and apartments where microwave beeps are a nuisance.
This GE packs five functions (microwave, air fry, convection, broil, and reheat) into a 1.0 cu ft frame, and the 1050W microwave power is slightly higher than the 900W competitors — that means it shaves seconds off reheating compared to the BLACK+DECKER. The included stainless steel crisper pan delivers golden, crispy results without needing a second appliance. The convenience cook controls (Pizza, Popcorn buttons) make daily use simple. However, a handful of owners mention units that fail to reach set temperatures — one reviewer measured a 375°F setting actually only hitting 176°F — and GE’s warranty process has frustrated some.
The face panel is hard to read in dim light, and the turntable latch feels fragile to some. For the crowd that values quiet and brand familiarity, this is a balanced pick — just buy from a seller with a low-maintenance return window in case of a lemon.
The big plus: genuinely quiet operation that does not wake up the house during late-night snack runs — a clear edge over the louder FRIGIDAIRE.
The honest caution: temperature accuracy is a gamble on some units, making the convection bake function unreliable from the start for some buyers.
4. Midea 4-in-1 Multifunctional Microwave Steam Oven, 0.9 cu ft
A four-in-one that steams vegetables and air-fries chicken in the same box — unique in this class, but the small 0.9 cu ft interior limits what fits.
This Midea is the only unit in the lineup that adds true steam cooking alongside microwave, air fry, and baking. Its dual steam tubes release high-temperature steam that envelops food within 30 seconds, so you can steam purple potatoes at 250°F or cook spa eggs at 125°F while retaining more nutrients. The graphene heating element (a material that heats and cools very quickly) in the air fryer delivers quick heating for crispier results. The color touch screen and 32 auto functions (including ferment, defrost, and cavity cleaning) give you the most cooking modes of any unit here. Owners who use the steam function call it excellent for RV and small-space living, and the downward-opening door is a space-saving convenience. The trade-offs are real: the interior is small for tall items, and the time dial starts at 30 minutes, making short bursts tricky. A few units have had door handle breakage near the end of the return window.
If steam cooking (sourdough fermentation, delicate fish, nutrient-packed vegetables) is a primary need, this is the only combo oven that does it well. For pure microwave and air-fry performance, the simpler FRIGIDAIRE or Breville may be more reliable daily drivers.
What makes it special: the only steam-capable combo here — dual steam tubes lock in flavor and nutrients better than any other unit on this list, so vegetables stay crisp-tender.
The compromise: learning curve is steep; the manual is necessary reading, and the small interior limits what you can steam at once.
5. Breville BMO870BSS Combi Wave 3-in-1, Brushed Stainless Steel
The most thoughtfully designed interface on the market — the Breville actually teaches you how to cook with it, and the soft-close door is 80% quieter than standard microwaves.
Breville packs 1200W microwave power, 1400W convection, and 1100W grilling into a 1.1 cu ft brushed stainless body. The Element IQ system (smart algorithms that steer power where and when it is needed) makes a frozen pizza cook through without a burnt crust — unlike the FRIGIDAIRE which requires more manual tweaking. The soft-close door is 80% quieter than standard microwaves, and the overall operation is 50% quieter. The time dial adjusts intuitively, you can change power level mid-cook, and the “A Bit More” button adds proportional time instead of a flat 30 seconds. Smart Cook, Smart Reheat, and Smart Defrost presets take the guesswork out of tricky tasks like defrosting meat without cooking the edges. On the downside, the air fryer is slower to heat than standalone units, and grill element cleaning is fiddly.
Durability is the main concern at this price point: multiple customers note needing replacements within a year due to door soft-close failure or unit death. When it works — which is most of the time for most owners — it is the most intuitive and capable combo oven available. The warranty process requires phone calls, so buy from a retailer with easy returns.
Controls that work
- top-tier interface with intuitive dial and power-level adjustments
- Smart presets that actually work for defrosting, reheating, and cooking from frozen
- Soft-close door and quiet operation are a joy in small spaces
The cost of precision
- Air fryer preheats slowly compared to dedicated air fryers
- Some units suffer from door mechanism failure within the first year
- Premium price does not guarantee low-maintenance long-term reliability
Best for: the home cook who values intuitive controls and precision reheating over raw power — if you want automatic results for frozen pizza, this beats the FRIGIDAIRE hands-down.
Think twice if: you need a rugged unit for heavy daily air-frying; the AAOBOSI or FRIGIDAIRE is more durable for that use pattern.
6. AAOBOSI 24 Inch Built-in Microwave Convection Oven, 1.6 Cu.Ft
A 1.6 cu ft built-in that replaces your microwave, air fryer, and convection oven in one permanent cabinet slot — the largest capacity and most powerful convection here.
This AAOBOSI is the largest unit here by a wide margin — 1.6 cu ft of interior space holds a 14-inch pizza or a large roasting pan with room to spare. It is a built-in model (24-inch width) that installs flush into a cabinet cutout, giving your counter a clean, smooth look. The cooking power is equally big: 1000W microwave, 1700W convection element, and 1750W broil element for serious browning — that is more convection power than the Breville’s 1400W. The glass touch control panel and 12 cooking functions (plus sensor cooking that automatically adjusts time and power) make it feel modern. Owners rave about the sleek stainless steel appearance and the drop-down door that stays sturdy. The included accessories — turntable, ceramic tray, grill rack, grill pan, and wire mesh rack — cover every cooking scenario.
The catch is installation: the unit weighs 90 pounds and requires a 20-amp dedicated circuit (a heavy-duty electrical line), so this is not a casual countertop swap. A few owners note the plug requires a separate adapter. If you are renovating your kitchen and want one appliance to handle everything from toast to roast turkey, this is the endgame pick. For renters or anyone who does not own their cabinets, stick with the countertop FRIGIDAIRE or Breville.
For the settled kitchen: the largest capacity, most powerful convection, and a built-in fit that frees up counter space permanently — a true alternative to the Breville if you are remodeling.
Installation reality check: 90 pounds, 20-amp circuit required, and a 24-inch cabinet cutout — plan your kitchen remodel around this one.
Understanding the Specs
Microwave Wattage and Inverter
Microwave wattage (usually 900W to 1200W) directly controls how fast your leftovers and frozen meals heat. Higher wattage means faster cooking. Inverter technology (like the Breville’s Power Smoothing Inverter) delivers consistent low power for gentle defrosting and chocolate melting, whereas standard microwaves pulse on and off at low settings, which can overcook edges.
Convection vs Standard Fan
A true convection oven uses a heating element plus a fan that circulates hot air around the food, producing even browning — essential for cookies, roasted vegetables, and reheating pizza so the crust stays crispy. A standard “fan” microwave just moves air without heat, so the interior stays cool. Check whether your oven has a separate convection element (the FRIGIDAIRE and AAOBOSI do) or just a combo grill.
Sensor Cooking and Auto Menus
Sensor cooking (found on the AAOBOSI and GE) uses internal sensors to detect steam and humidity, automatically adjusting power and time — so you do not overheat your soup or burn your popcorn. Auto menus (like Potato, Pizza, Popcorn) are pre-programmed shortcuts. More presets are not always better; look for quality of the top three you will actually use (reheat, defrost, popcorn).
Capacity and Footprint Trade-offs
Interior capacity is measured in cubic feet (0.9 to 1.6 for these units). A 0.9 cu ft oven fits a standard dinner plate but not a 12-inch pizza. A 1.2 cu ft or larger handles full casseroles and a whole chicken. But remember: exterior dimensions matter just as much. A 0.9 cu ft BLACK+DECKER is compact enough for a shelf, while the 1.6 cu ft AAOBOSI needs a dedicated 24-inch cabinet.
