Our Picks: Best Oven And Microwave In One Unit reviews
1. TOSHIBA Air Fryer Combo Microwave: A versatile all-in-one pick
This TOSHIBA combines eight functions in one countertop appliance: microwave, air fry, convection bake, broil, combination cooking, low-temperature cooking, odor removal, and defrost. That range makes it a flexible choice if you want to handle everyday reheating as well as crisping, baking, and browning without keeping several separate appliances on the counter.
The 1.0-cubic-foot capacity is paired with a 12.4-inch removable turntable. TOSHIBA says it can fit a whole roasted chicken, a 12-inch pizza, or an 8-by-4-inch casserole. Its listed exterior dimensions are 20.6 by 16.4 by 11.8 inches, which is useful to check against your available counter space before buying. Microwave output is listed at 1,000 watts.
The range of functions is its main advantage, but it also means there may be more controls to learn than on a basic microwave. The two-step child lock adds a safety feature for households with younger family members. Compared with the Breville, this model offers more named cooking modes; the Breville, in turn, emphasizes inverter control and preset programs.
Pros:
- Eight listed cooking and utility functions
- Removable turntable is sized for several common meals, including a 12-inch pizza
- Compact 1.0-cubic-foot capacity with listed exterior dimensions
- Includes a two-step child lock
Cons:
- Its 1.0-cubic-foot capacity may be limiting for larger dishes
- The many modes may take time to learn if you prefer simple controls
Verdict: Choose this TOSHIBA if you want a compact microwave with a broad mix of air-fry, oven, broil, and utility functions.
2. Breville Combi Wave 3-in-1: A feature-rich microwave and convection combo
The Breville Combi Wave brings together a microwave, convection oven, and air fryer in a 1.1-cubic-foot unit. Its Fast Combi function combines convection, grilling, and microwave cooking, while Cook From Frozen is designed for cooking frozen food. Those options make it a good fit if you expect to use more than basic microwave settings.
Its Element IQ system directs power for different cooking tasks, and the inverter microwave adjusts power intensity for reheating and defrosting. The unit has 19 built-in smart presets, plus dedicated controls for functions such as Smart Cook, Smart Reheat, Air Fry, Oven, Microwave, and Grill. A Combi Crisp Pan and trivet are included, giving you accessories for different cooking methods.
The soft-close door, mute button, and child lock are practical touches for a shared kitchen or open living space. The listed input power varies by function: 1,200 watts for microwave, 1,400 watts for convection, and 1,100 watts for grill. Its controls and presets are more extensive than those of a simple microwave, so it may be more appliance than you need if you mainly reheat drinks and leftovers.
Pros:
- Combines microwave, convection oven, and air fryer functions
- Inverter microwave adjusts power intensity for cooking and defrosting
- Includes 19 smart presets, a Combi Crisp Pan, and a trivet
- Soft-close door, mute option, and child lock
Cons:
- Its wide range of presets and functions may feel complex for basic microwave use
- Listed power input differs by cooking mode, so check your kitchen setup and the product instructions
Verdict: The Breville is a strong choice if you want a three-in-one appliance with inverter microwave control, combination cooking, and a broad set of presets.
3. TOSHIBA OptiChef Pro: A focused pick for air frying and defrosting
This 1.0-cubic-foot TOSHIBA is built around microwave cooking, air frying, and convection modes. Its top-mounted heating element and 360-degree air circulation are intended to crisp foods such as wings, fries, and frozen snacks. The design targets cooks who want an air-fry option without adding a separate appliance.
The Origin Inverter system is described as regulating temperature for more even heating, while ChefDefrost uses weight detection to thaw food. TOSHIBA says ChefDefrost can thaw food 40% faster; treat that as a manufacturer-listed feature rather than a guarantee for every item or setting. The large LED screen, 24 auto menus, and 10 power levels give you several ways to select and adjust cooking.
Compared with the first TOSHIBA, the OptiChef Pro highlights inverter control, a more detailed defrost system, and one-touch menus, while the other model lists more total functions. The product information does not specify exterior dimensions, turntable size, or included accessories, so check those details if fit or cooking setup is important to you.
Pros:
- Combines microwave, air-fry, and convection modes
- Top-mounted heating element and circulating air are designed for crisping
- Inverter control and weight-detecting ChefDefrost
- 24 auto menus and 10 power levels
Cons:
- Exterior dimensions and turntable size are not provided in the supplied product details
- Included accessories are not specified
Verdict: Consider the OptiChef Pro if crisping, defrost controls, and guided cooking menus matter more to you than a long list of specialized modes.
4. TOSHIBA 4-in-1: The largest-capacity choice in this group
At 1.5 cubic feet, this TOSHIBA has more stated capacity than the other models in this comparison. It combines microwave, air-fry, convection, and microwave-plus-convection cooking. The 13.6-inch removable turntable is listed as large enough for a whole roasted chicken or a 12-inch pizza, making this a better fit on paper for larger portions.
Useful features include auto bake, auto roast, defrost programs, and sensor menus for foods such as frozen pizza and vegetables. It also has a mute function, memory, speedy cooking, and multistage cooking. Microwave power is listed at 1,000 watts, with 10 power settings. Its exterior measures 21.8 by 20.0 by 12.9 inches, so allow for its larger footprint when measuring your counter.
The product information lists a turntable, grill rack, and grill tray as included components. One important caveat: this item is marked unavailable in the supplied availability information. Availability can change, but confirm that it can be ordered before settling on this model. If it is not available, the GE or Breville may be more practical alternatives, depending on whether you prioritize accessories or preset cooking features.
Pros:
- Largest stated capacity in this comparison at 1.5 cubic feet
- 13.6-inch turntable is listed for a whole chicken or 12-inch pizza
- Includes a grill rack and grill tray
- Sensor menus, mute function, and multistage cooking add convenience
Cons:
- Marked unavailable in the supplied availability information
- Larger exterior dimensions require more counter space than the 1.0-cubic-foot options
Verdict: This is the capacity-focused option if you need room for larger dishes, but confirm availability before making it your first choice.
5. GE 4-in-1 Air Fry Countertop Microwave: A compact option with included accessories
This GE combines microwave, air-fry, convection, and broil functions in a 1.0-cubic-foot countertop unit. It is listed at 1,050 watts of cooking power and includes a stainless steel crisper pan for air frying, a tall wire rack for broiling, and a short wire rack for convection cooking. Having the accessories included makes it easier to use the different modes as intended.
For everyday use, the microwave has convenience controls for foods such as pizza and popcorn, along with a child lock. GE also describes the unit as quiet-operating, which may be useful in an apartment, dorm, or office. For airflow, the product information calls for 3 inches of clearance on each side and above, 1 inch at the rear, and an unobstructed bottom.
Its 1.0-cubic-foot capacity is less than the larger TOSHIBA 4-in-1, but the GE includes clear mode-specific accessories and broiling alongside air frying and convection. If you need a larger turntable or want details about cooking capacity beyond the stated cubic footage, check the product listing and manual before purchasing.
Pros:
- Four listed functions: microwave, air fry, convection, and broil
- Includes a crisper pan and two wire racks for different cooking modes
- Child lock and convenience cook controls
- Provides specific clearance guidance for countertop placement
Cons:
- 1.0-cubic-foot capacity may not suit larger dishes or portions
- Requires airflow clearance on the sides, top, and rear
Verdict: Choose the GE if you want a straightforward four-function combo with the cooking accessories included and have room to meet its clearance requirements.
How to Choose an Oven and Microwave in One Unit
Match the functions to the way you cook
Start with the cooking methods you will use most. A microwave with air fry and convection can cover reheating, browning, and baking, while broil or grill modes add another way to brown food. Combination cooking can bring microwave energy together with convection, but not every model offers the same modes. Compare the listed functions rather than relying only on a “3-in-1” or “4-in-1” label.
Check capacity and turntable size
Cubic footage gives you a general sense of interior capacity, but the turntable and usable space matter too. A larger pizza or casserole may not fit even if the capacity sounds adequate. Among these picks, the 1.5-cubic-foot TOSHIBA has the largest stated capacity and a 13.6-inch turntable; several others are 1.0 cubic foot. Measure the dishes you use most and compare them with the product’s stated dimensions.
Measure your counter and plan for airflow
Measure the available width, depth, and height before choosing a countertop unit. Account for the space needed to open the door and for any ventilation gaps required by the manufacturer. The GE lists specific clearance needs on its product information. For other models, check the product instructions rather than assuming that all countertop combos need the same spacing.
Consider power and your kitchen setup
Microwave output and appliance input power are not always the same figure. For example, the first TOSHIBA lists 1,000 watts of microwave output, while the Breville provides separate input-power figures for its microwave, convection, and grill modes. Check the product specifications and instructions for the model you choose, especially if you plan to use more than one cooking function regularly.
Look at controls, presets, and safety features
Auto menus and shortcuts can make frequent tasks easier, while adjustable power levels give you more control. A large set of settings may take longer to learn, so consider whether you prefer guided presets or simple manual controls. If children use the kitchen, check how the child lock works. The TOSHIBA Air Fryer Combo has a two-step child lock, while the Breville and GE also list child-lock features.
Check which accessories are included
Air-fry pans, trays, and racks can affect how easily you use the oven functions. The Breville includes a Combi Crisp Pan and trivet; the GE includes a crisper pan and two wire racks; and the larger TOSHIBA lists a grill rack and grill tray. Included accessories vary, so check the exact package details and follow the manual’s guidance about which pieces are safe for each mode.
Think about cleanup and everyday convenience
A removable turntable can make cleaning easier, and features such as a mute function or a soft-close door may matter in a shared living space. The TOSHIBA models list removable turntables, while the Breville offers a mute button and soft-close door. Consider which conveniences you will notice most in your daily routine, rather than choosing based on the longest feature list alone.
Frequently Asked Questions
Can a microwave-convection combo replace a full-size oven?
It can handle some oven-style tasks, such as baking or roasting, depending on its modes and capacity. These countertop units are smaller than full-size ovens, so they may not fit large cookware or prepare the same amount of food at once. Check the interior dimensions and the instructions for the model you are considering.
What is the difference between convection and air fry?
Both use circulating hot air, but the appliance may use different heating elements, accessories, or settings for each mode. In these product listings, air-fry features are described as helping crisp food, while convection is used for oven-style cooking. Follow the unit’s manual for recommended cookware and settings.
Do these appliances microwave and bake at the same time?
Some models include combination cooking that uses microwave and convection together. The first TOSHIBA lists a combination mode, and the larger TOSHIBA describes microwave-plus-convection cooking. The Breville also lists Fast Combi, which combines convection, grilling, and microwave cooking. Check each model’s instructions for suitable foods and cookware.
Which model has the largest stated capacity?
The TOSHIBA 4-in-1 Microwave with Air Fryer has the largest stated capacity in this group at 1.5 cubic feet. It also has a 13.6-inch turntable. The supplied availability information marks it unavailable, so confirm that it can be ordered before choosing it.
Which option includes the most cooking accessories?
The GE lists three accessories: a stainless steel crisper pan, a tall wire rack, and a short wire rack. The Breville includes a Combi Crisp Pan and a trivet, while the larger TOSHIBA lists a grill rack and grill tray. Check the listing for the latest package details before ordering.
How much counter clearance does a combo microwave need?
Clearance requirements depend on the model. The GE product information calls for 3 inches on each side and above, 1 inch at the rear, and an unobstructed bottom. For other models, consult the manual or product instructions and leave the required space for airflow.
Final Recommendation
For a balanced mix of cooking options in a compact footprint, the TOSHIBA Air Fryer Combo Microwave is the most versatile choice in this group based on its eight listed functions and 12.4-inch turntable. Pick the Breville if inverter control and smart presets are priorities, or the GE if you want included racks and a crisper pan. The larger TOSHIBA is worth considering for its capacity, but confirm availability first.
