Our Picks: Best All In One Microwave And Oven reviews
1. TOSHIBA 8-in-1 Combo: A Flexible Pick for Small Counters
This 1.0-cubic-foot TOSHIBA combines a microwave with air fry, convection bake, broil, combination cooking, low-temperature cooking, odor removal, and defrost. Its 1,000-watt microwave output covers routine reheating and cooking, while the additional modes let you crisp or brown food without a second countertop appliance.
The 12.4-inch removable turntable is designed to accommodate items such as a 12-inch pizza, a whole roasted chicken, or an 8-by-4-inch casserole, according to the product description. The black stainless-steel finish gives it a darker look than the standard stainless models here. A two-step child lock is also included.
Its main advantage is the number of cooking options in a relatively compact capacity. The trade-off is that it offers less stated interior space than the 1.1- and 1.5-cubic-foot models below. If you often cook large dishes, check their dimensions against the turntable and cavity before buying.
Pros:
- Eight listed cooking and convenience functions
- 12.4-inch removable turntable fits several common dishes
- Includes air fry, convection bake, and broil modes
- Two-step child lock
Cons:
- Smaller capacity than the larger TOSHIBA 4-in-1 model
- Its many modes may take time to learn if you want simple controls
Verdict: Choose this TOSHIBA if you want several cooking modes in a compact countertop unit and can work within a 1.0-cubic-foot capacity.
2. Breville Combi Wave: Smart Controls for Mixed Cooking
The Breville Combi Wave brings together a microwave, convection oven, and air fryer in a 1.1-cubic-foot appliance. It also has a grill function and combination settings that pair microwave energy with oven or grill heat. Fast Combi and Cook From Frozen are designed to speed up certain cooking tasks by using more than one method.
Its inverter microwave adjusts power intensity instead of relying only on repeated full-power bursts. The appliance also offers 19 built-in smart presets for cooking, reheating, and defrosting. A shortcut panel inside the door covers common tasks such as softening butter and reheating pizza. The package includes a Combi Crisp Pan and trivet.
Convenience features include a soft-close door, a mute option, and a Child Lock. Breville lists separate input power figures for microwave, convection, and grill modes, so this model has several distinct cooking systems rather than one single power rating. It is a strong match if you value presets and combination cooking, though it may be more feature-rich than needed for basic reheating.
Pros:
- Combines microwave, convection oven, air fry, and grill functions
- Inverter technology adjusts microwave power intensity
- Includes 19 presets and a useful shortcut panel
- Soft-close door, mute option, and child lock
Cons:
- Several modes and presets may feel complex for a simple-use household
- Listed capacity is smaller than the 1.5-cubic-foot TOSHIBA option
Verdict: Pick the Breville if you want guided settings and the ability to combine microwave speed with convection or grill heat.
3. Sharp 3-in-1: A Compact Microwave, Convection, and Air Fryer
Sharp’s 0.9-cubic-foot model combines three core functions: microwave cooking, convection baking, and air frying. The product title lists 900 watts, and the smaller capacity makes this the most compact choice by stated volume in this group. It may suit a small kitchen or a household that does not regularly cook large portions.
The appliance has preset controls for common foods and beverages, plus a +30 key for quickly adding cooking time. Its auto-defrost function can be combined with later cooking and crisping stages in one operation. The stainless-steel interior is paired with LED lighting, and the included air fry basket is dishwasher-safe. A baking or roasting pan and 10.6-inch glass turntable are also included.
Compared with the other picks, the Sharp gives up some capacity and has fewer listed cooking modes. In return, its straightforward three-function focus may be easier to manage if you do not need broiling, grill settings, or a long menu of specialty options. Confirm that the turntable and interior suit your usual plates and cookware.
Pros:
- Combines the three main functions many shoppers want
- Includes a dishwasher-safe air fry basket and baking or roasting pan
- Multi-stage cooking can combine defrosting, cooking, and crisping
- Compact 0.9-cubic-foot capacity
Cons:
- Smallest stated capacity in this comparison
- Fewer listed cooking modes than the multi-function TOSHIBA options
Verdict: The Sharp is a sensible choice when counter space matters more than extra capacity or a wide range of specialty modes.
4. TOSHIBA 4-in-1: More Room for Family-Size Dishes
This TOSHIBA has the largest stated capacity in the group at 1.5 cubic feet. It combines microwave cooking, air frying, convection, and combination cooking, which uses microwave and convection together. The product description says its 13.6-inch turntable can fit a whole roasted chicken or a 12-inch pizza.
Features include a pre-programmed sensor menu, auto bake, auto roast, defrosting, one-touch popcorn, and multi-stage cooking. The stainless-steel interior is designed to be easy to clean, and the package includes a turntable, grill rack, and grill tray. A mute function is available through the control keypad.
This model is a better match for larger dishes than the 0.9- and 1.0-cubic-foot picks, but it also has a larger listed exterior footprint: 21.8 by 20.0 by 12.9 inches. The supplied product information marks it unavailable. Check its Amazon listing for current availability before making it part of your shortlist.
Pros:
- Largest stated capacity in this comparison
- 13.6-inch turntable is sized for larger dishes
- Includes microwave, air fry, convection, and combination cooking
- Sensor menu and mute function add convenience
Cons:
- Needs more counter space than the smaller-capacity models
- The supplied listing information marks it unavailable
Verdict: Consider this TOSHIBA if capacity is your priority, but verify availability and measure your counter before choosing it.
5. TOSHIBA OptiChef Classic: A Feature-Rich Option for Small Kitchens
The OptiChef Classic combines a microwave, air fryer, convection oven, and broiler in a 1.0-cubic-foot countertop unit. Its listed exterior dimensions are 20.6 inches wide, 16.3 inches deep, and 11.8 inches high. The product description calls for three inches of side clearance, three inches above, and one inch at the rear, so include that space when checking whether it will fit.
TOSHIBA lists 1,000-watt microwave output, inverter technology, a humidity sensor, and 27 automatic menus. The description also specifies a 360-degree fan and top heating element, with an advertised air-fry temperature of up to 425°F. Smart Combi mode is designed to combine microwave speed with convection or broil heat. These features make it a flexible option, but the number of settings may be unnecessary if you mostly reheat food.
The stainless-steel exterior and interior are paired with a dishwasher-safe air fry basket. Included accessories are listed as an air fry basket, baking tray, two wire racks, and crumb tray. Its capacity is similar to the first TOSHIBA pick, but it offers a different control and accessory package. The product description states a one-year comprehensive warranty.
Pros:
- Combines microwave, air fry, convection, and broil functions
- Includes 27 automatic menus and a humidity sensor
- Comes with several cooking accessories
- Lists required clearance dimensions for countertop planning
Cons:
- Requires clearance around the unit beyond its listed exterior dimensions
- Its many automatic menus may be more than a basic microwave user needs
Verdict: Choose the OptiChef Classic if you want a broad set of modes and accessories in a one-cubic-foot unit, and have room for its required ventilation clearances.
How to Choose an All-in-One Microwave and Oven
Match capacity to the dishes you use
Capacity gives you a starting point, but it does not tell the whole story. Check the turntable size, interior layout, and the dimensions of your regular plates, casserole dishes, or baking pans. The Sharp has the smallest listed capacity at 0.9 cubic feet, while the 1.5-cubic-foot TOSHIBA offers more stated room for larger dishes.
Choose cooking modes you will actually use
Most models here combine a microwave with air frying and convection. Some add broiling, grilling, low-temperature cooking, or combination modes. If you mainly reheat and occasionally crisp food, a simpler three-function model may be enough. If you plan to roast, bake, or use combined cooking often, compare the specific modes and presets instead of choosing by the largest number of functions.
Measure the counter and required clearance
Measure the appliance’s full exterior footprint, then check the manufacturer’s clearance instructions. The OptiChef Classic lists required space around its sides, top, and rear, so its fit depends on more than its width, depth, and height. Also account for room to open the door and safely handle hot accessories.
Look at power and cooking controls
Microwave wattage is useful for comparing microwave output, but combination appliances may list separate power figures for different modes. Features such as inverter power, sensor cooking, automatic menus, and multi-stage programs can affect how much control you have. Consider whether you prefer guided presets or manual settings.
Check the included accessories and cleaning needs
Air fry baskets, trays, racks, and turntables can make a combo oven more useful, but their materials and cleaning instructions matter too. For example, the Sharp listing specifies a dishwasher-safe air fry basket, and the OptiChef Classic lists a dishwasher-safe basket along with several other accessories. Confirm which parts are included with the exact listing you choose.
Think about what a countertop combo can replace
These appliances can combine several countertop functions, but their capacity and cooking modes differ. Consider the foods and portions you make most often before deciding whether a combo can take the place of a separate air fryer or toaster oven for your needs. Check cookware fit and the appliance’s instructions rather than assuming every function handles every dish the same way.
FAQs
Can an all-in-one microwave also air fry food?
Yes. All five models in this guide list an air-fry function. The available accessories and cooking settings vary, so check each model’s included basket and instructions.
What is the difference between convection and combination cooking?
Convection uses heated air to cook food. Combination cooking uses microwave energy along with another cooking method, such as convection. The exact modes vary by model.
Which model has the most capacity?
The TOSHIBA 4-in-1 model has the largest stated capacity here at 1.5 cubic feet. The supplied product information marks it unavailable, so check its listing before planning to buy it.
Which option is smallest by stated capacity?
The Sharp is listed at 0.9 cubic feet, making it the smallest by capacity among these picks. Check its exterior dimensions and 10.6-inch turntable against your available counter and usual dishes.
Do these appliances replace a full-size oven?
They provide countertop microwave and oven-style functions, but capacity and modes differ from one model to another. Whether one can replace a full-size oven for you depends on the portions you cook and the dishes you use.
What should I measure before ordering?
Measure the available counter width, depth, and height, and leave the clearance listed for the model. Also check the door-opening area, turntable size, and fit of your cookware.
Final Recommendation
For a balanced mix of countertop-friendly size and multiple cooking modes, the TOSHIBA 8-in-1 is a strong starting point. Choose the Breville if you value presets and combination cooking, the Sharp if you want a smaller-capacity three-function unit, or the OptiChef Classic for its included accessories and broad settings. If larger dishes are your priority, the 1.5-cubic-foot TOSHIBA is worth checking when its listing shows availability.
