Counter space is the most expensive real estate in any kitchen, and stacking a separate microwave, toaster oven, and air fryer is a recipe for clutter. An all-in-one oven and microwave consolidates reheating, baking, air frying, broiling, and defrosting into a single footprint, letting you cook a frozen pizza to crispy perfection or reheat last night’s pasta without breaking out three different appliances.
I’m Min — the co-founder and writer behind Gadgets Feed. I’ve spent countless hours comparing inverter technologies, convection airflow designs, and smart presets across dozens of combo units to separate the true kitchen workhorses from the underpowered compromises.
Whether you’re outfitting a small apartment kitchen or upgrading your cooking arsenal, finding the best all-in-one oven and microwave means balancing cooking versatility with reliable everyday performance.
How To Choose The Best All-In-One Oven And Microwave
Choosing a combo unit requires looking past the number of functions advertised and focusing on the quality of each cooking mode. A machine that microwaves poorly but air fries well is still a compromise. The key factors are the type of microwave technology, the heating element power for convection tasks, and the physical capacity relative to your counter depth.
Inverter vs. Standard Microwave Power
Standard microwaves pulse the magnetron on and off at lower power levels, which can overcook edges while leaving the center cold. Inverter technology delivers a continuous stream of power, allowing for gentle defrosting that thaws meat without cooking the outer layer and more consistent reheating of dense leftovers. This is a defining feature for any premium unit.
Convection Wattage and Air Fry Performance
Not all convection systems are equal. Top-mounted heating elements with 360-degree fan circulation produce noticeably crispier air-fried food than rear-mounted fans. Look for models that specify a dedicated convection or broil wattage above 1400W if you plan to bake or air fry regularly. Lower wattage units may struggle to brown food evenly.
Capacity and Physical Footprint
Interior capacity is measured in cubic feet, but the usable flat area matters more. A 1.2 cu. ft. oven with a 15-inch turntable fits a large pizza or a whole chicken, while a 0.9 cu. ft. unit might only accommodate a 10-inch plate. Always measure your counter depth and height — many combos are taller than standard microwaves, and built-in models require specific cabinet dimensions.

In‑Depth Reviews
1. Breville BMO870BSS Combi Wave 3-in-1
The Breville Combi Wave sets the benchmark for what a countertop combo oven should be. Its Element IQ system dynamically adjusts power between the 1200W inverter microwave, 1400W convection element, and 1100W grill to create tailored cooking environments. The Fast Combi mode merges all three heat sources to dramatically reduce roasting times, while the Cook from Frozen function delivers surprisingly even results without pre-thawing.
Build quality is unmistakably premium — the soft-close door is noticeably quieter than any competitor, and the brushed stainless steel finish resists fingerprints. The jog dial and button interface is intuitive, and the Shortcuts panel inside the door provides one-touch access to common tasks like melting chocolate or softening butter. The included Combi Crisp Pan is essential for air frying and should live in the oven permanently.
At 1.1 cu. ft., the internal capacity is adequate for a 12-inch pizza or a small chicken, but it won’t fit a large sheet pan. Some users report that longer cook times require adding a few minutes compared to full-sized ovens. The end-of-cycle beep is audible even on its lowest setting, though the mute button eliminates it entirely. For those who value cooking precision and build quality above all else, this is the unit to beat.
Why it’s great
- Element IQ delivers precise, even cooking across all modes
- Soft-close door and 50% quieter operation than typical microwaves
- Smart presets for defrost, reheat, and cook from frozen are highly reliable
Good to know
- Interior is relatively small for a 1.1 cu. ft. unit
- Air fryer operation is effective but slower than dedicated air fryers
- Higher investment cost compared to mid-range combos
2. Samsung 1.2 cu. ft. Countertop Convection Microwave with Air Fry
Samsung brings smart home integration to the combo category with this 1.2 cu. ft. countertop oven. The Power Convection system circulates hot air to cook up to 30% faster than standard convection, and the PowerGrill Duo adds a wide grilling element for browning steaks or melting cheese on casseroles. The black glass finish and touch controls give it a sleek, modern look that blends into higher-end kitchens.
Wi-Fi connectivity via SmartThings Food unlocks guided cooking with recipe recommendations and remote monitoring. Voice control through Bixby, Alexa, or Google Assistant means you can check if dinner is done without walking to the kitchen. The 15-inch turntable is among the largest in its class, easily accommodating a 14-inch pizza. The air fry mode uses a dedicated basket and produces respectable crispiness on frozen items.
Reliability feedback is mixed — while many praise the aesthetics and ease of use, a notable number of users report that the grill and air fry functions lack sufficient heat output for thorough cooking. The touch interface can be finicky, and the door design is not a standard swing-open but a drop-down style that requires counter clearance. For smart home enthusiasts willing to accept some variability in cooking performance, the Samsung remains a compelling choice.
Why it’s great
- Large 15-inch turntable fits full-size pizzas
- Wi-Fi and voice control via SmartThings app
- PowerGrill Duo adds browning capability beyond air frying
Good to know
- Air fry and grill heat output reported as inconsistent by some users
- Drop-down door needs extra front clearance
- Higher price point for a countertop model with mixed cooking reviews
3. Panasonic HomeChef 4-in-1 NN-CV87QS
Panasonic’s HomeChef combines microwave, air fryer, convection oven, and broiler into a single 1.2 cu. ft. footprint with a 14.2-inch turntable. The 1000W Inverter microwave technology is legendary for gentle defrosting and even reheating, and it pairs here with a dedicated convection fan and top-mounted broiler. The 4-in-1 capability is genuinely useful — you can air fry chicken wings, then switch to convection bake for cookies without swapping appliances.
The standout feature is the Panasonic Kitchen+ app, which pairs with the oven to send recipes directly to its controls. The dial interface is refreshingly simple compared to touch-only competitors, and the ceramic enamel interior wipes clean easily. The air fry basket is generously sized but tall items may not fit under the broiler element. The three available air fry temperatures (400-425°F) are somewhat limited for advanced cooking.
Reliability is generally strong, but the child lock implementation is frustrating — it requires holding the Timer/Clock button to unlock, and a power outage resets the lock state. The glass turntable rotates in all modes, which can be noisy with the included wire rack. For cooks who want a true kitchen relay that handles everything from delicate defrosting to crispy air frying, the Panasonic delivers consistent performance with the backing of a trusted brand.
Why it’s great
- Legendary Inverter technology for precise, gentle heating
- Kitchen+ app enables guided, hands-off cooking
- Compact footprint relative to its 1.2 cu. ft. capacity
Good to know
- Air fry mode has only three temperature presets
- Child lock mechanism is finicky and resets after power loss
- Turntable rotates in all modes, creating potential noise
4. TOSHIBA Optichef Pro MAX ML2-STC13SAIT(SS)
The Optichef Pro MAX is Toshiba’s largest and most feature-rich combo, packing a 1.3 cu. ft. cavity with a 2.4-inch color screen that makes navigating the 24 auto menus genuinely easy. The Origins Inverter technology provides smooth power delivery for even defrosting and reheating, and the ChefFry Plus top-fan system circulates 360-degree hot air for air frying. The humidity sensor automatically adjusts cooking time based on moisture levels, which works well for steaming vegetables.
Alexa compatibility lets you start or stop the microwave with voice commands, and the ceramic enamel interior is far easier to clean than standard painted cavities. The 16.4 x 9.3-inch cavity fits a 13-inch pizza flat, and the 1100W output is competitive with similarly priced units. The included wire rack is essential for air frying and convection baking.
Build quality concerns are the primary drawback. Some units have been reported to fail due to steam damage within months, and the 2.4GHz-only Wi-Fi setup can be frustrating for users with mesh networks. The low interior height (9.3 inches) limits what you can stack, and the turntable can be noisy during rotation. For buyers who want a large-capacity smart combo with Alexa integration, the Pro MAX offers strong value if you can accept the reliability risk.
Why it’s great
- Generous 1.3 cu. ft. capacity fits a whole chicken
- Color touchscreen with 24 auto menus simplifies operation
- Alexa voice control for hands-free use
Good to know
- Reports of early failure due to steam ingress
- Low interior height limits stacking in the cavity
- Wi-Fi setup requires 2.4GHz network only
5. TOSHIBA Optichef Pro ML2-EC10SAITC(BS)
The standard Optichef Pro delivers the same core air fry and inverter technology as its MAX sibling in a more affordable 1.0 cu. ft. package. The ChefDefrost system uses weight detection to thaw meat 40% faster than conventional defrost, and the top-mounted fan circulates heat for crispy air-fried results on wings and fries. The 24 one-touch auto menus and 10 power levels cover most daily cooking scenarios without needing to memorize cooking charts.
The user interface combines a large LED screen with buttons and knobs, which many find more intuitive than full touch interfaces. The black stainless steel finish resists smudges, and the child safety lock is a standard inclusion. The 18.1 x 20.6 x 11.8-inch footprint is compact enough for smaller counters while still fitting a 16-inch pizza flat on the turntable.
As with the Pro MAX, reliability concerns are present — some units have failed due to steam damage, and the 1100W output may feel weaker than a dedicated 1200W microwave, requiring slightly longer cook times. The manual is notoriously confusing, and the low interior height (approximately 8 inches) prevents using tall containers. For budget-conscious buyers who want a genuine inverter-based air fryer microwave combo, this is a capable entry point.
Why it’s great
- ChefDefrost thaws meat 40% faster without cooking edges
- Compact footprint fits smaller countertops
- 24 auto menus simplify daily cooking
Good to know
- Early failure reports related to steam damage
- Low interior height limits cooking versatility
- 1000W output may require longer cook times than 1200W units
6. Midea 4-in-1 Multifunctional Microwave Steam Oven
The Midea 4-in-1 stands apart from every other combo on this list by adding genuine steam cooking to the mix. Dual steam tubes inject high-temperature steam that envelops food within 30 seconds, making it ideal for vegetables, fish, and dim sum. The 0.9 cu. ft. cavity is smaller than most combos, but the 23-liter capacity is adequate for a 10-inch pizza or a small roast chicken. The XpressFry mode uses True 3D Graphene heating elements for rapid thermal conductivity.
The color touchscreen control panel is responsive, and the 32 preset functions (24 pre-set menus plus 8 additional modes) include dedicated programs for defrost, ferment, keep warm, and even cavity deodorization and cleaning cycles. The ten convection temperature settings range from 225°F to 450°F, with 1500W of upper and lower baking tubes for more even baking than typical combos provide. The steamer function operates between 125°F and 250°F.
Reliability and performance consistency are concerns. Several reviews note that the air fry function does not crisp as effectively as dedicated air fryers, and the defrost cycle can partially cook food. The two included racks are non-standard sizes, making replacements difficult. The compact cavity and limited height mean larger casseroles won’t fit. For home cooks who prioritize steaming alongside microwave and convection capabilities, the Midea offers functionality no other combo here matches.
Why it’s great
- Dual steam tube injection for genuine steaming capability
- 32 preset functions including ferment and cleaning cycles
- Self-cleaning cavity deodorization and deep cleaning modes
Good to know
- Small 0.9 cu. ft. cavity limits dish size
- Air fry performance is weaker than dedicated units
- Non-standard rack sizes complicate replacements
7. BLACK+DECKER Over the Range Microwave with Air Fryer EC942K6CE-SS
The BLACK+DECKER is the only over-the-range model in this roundup, combining a microwave, air fryer, convection oven, and broiler with a 300 CFM two-speed vent fan and integrated cooktop light. The 1.5 cu. ft. interior with a 13.6-inch turntable is spacious enough for large casseroles, and the 900W output is lower than countertop models but standard for OTR units. The sensor reheat mode detects moisture levels to avoid overheating leftovers.
The six cooking modes — microwave, air fry, convection, combi grill, bake, and roast — are controlled via a touchscreen panel. The drop-down door is typical for OTR microwaves and includes a child safety lock. The stainless steel exterior matches standard kitchen appliances, and the interior is stainless steel for easy cleaning.
The lower 900W power means longer heating times compared to 1000W+ countertop units, and some users report that the air fry function is less effective than dedicated countertop combos due to the reduced wattage. The door opening mechanism can occasionally cause the unit to shift during heavy use. Installation requires proper clearance and venting, and the 89-pound weight makes it a two-person job. For those replacing an existing over-the-range microwave who want to eliminate a separate air fryer, this is a practical space-saving solution.
Why it’s great
- Frees up counter space by mounting over the range
- Built-in 300 CFM vent fan removes smoke and odors
- Large 1.5 cu. ft. interior fits family-sized dishes
Good to know
- 900W output is lower than countertop combos
- Air fry performance is weaker due to lower wattage
- Heavy unit requires professional-style installation
8. Gasland 24 Inch Built-in Microwave Oven
The Gasland 24-inch built-in microwave and convection oven combo offers a remarkably competitive price for a 1.6 cu. ft. wall oven replacement. The 3D convection heating system uses a fan to circulate hot air for even baking, and the 1000W microwave output handles standard reheating and defrosting duties. The three-layer tempered glass door stays cool to the touch, a critical safety feature for households with children.
The touch control panel includes eight auto-cook programs: popcorn, pizza, beverage, sensor cook, sensor reheat, auto defrost, frozen foods, and auto menu. The adjustable beep volume is a thoughtful touch for early-morning or late-night use, and the soft-close door operates quietly. The 23.43 x 17.87-inch exterior fits standard 24-inch cabinet openings, though it requires a 20A dedicated circuit.
Not all built-in combos include convection ovens at this price point, and the Gasland delivers on that promise. However, the unit weighs 89 pounds, making installation challenging without an assistant. Some units arrive with cosmetic damage from shipping, and the company’s customer service response time can be slow. The lack of air fry functionality means this is purely a microwave and convection combination — buyers seeking air frying should look elsewhere. For a straightforward built-in convection microwave, the Gasland offers significant value.
Why it’s great
- Substantial 1.6 cu. ft. capacity for a built-in
- Soft-close, quiet door with cool-touch glass
- Adjustable beep volume for discreet operation
Good to know
- No air fry mode — microwave and convection only
- Heavy unit complicates installation
- Shipping damage reported by some buyers
9. AAOBOSI 24 Inch Built-in Microwave Oven
The AAOBOSI 24-inch built-in goes beyond the Gasland by adding air fry and broil modes to its microwave and convection capabilities. The 1000W microwave features 10 power levels, while the 1700W convection element and 1750W broil element provide serious heat for browning and crisping. The 1.6 cu. ft. cavity includes a baking tray and grill rack, and the sensor cooking function automatically determines time and power for meat, vegetables, potatoes, seafood, and frozen foods.
The glass touchpad control panel is sleek and responsive, and the 10 cooking modes include auto defrost, soften/melt, sensor cook, sensor reheat, air fry, popcorn, pizza, beverage heat, broil, and convection. The child lock prevents accidental operation, and the stainless steel interior is easy to wipe down. The interior halogen lamp provides clear visibility through the insulated door glass. The unit requires a 20A plug, which may necessitate an electrical upgrade.
Build quality appears solid, but there are early reports of handle bars breaking, which raises durability concerns for a heavy appliance. The outward-downward drop door design requires substantial front clearance. The included baking tray and grill rack are useful but switching between them when changing cooking modes can be inconvenient. For buyers seeking a built-in solution that includes air frying without sacrificing microwave or convection performance, the AAOBOSI is a compelling contender at its price point.
Why it’s great
- Built-in design with air fry, broil, and convection in one unit
- Powerful 1700W convection and 1750W broil elements
- Sensor cooking auto-adjusts time for different food types
Good to know
- Requires a dedicated 20A electrical circuit
