Sharp SMC0985KS: A Compact Pick for Multi-Stage Cooking
The Sharp SMC0985KS combines a microwave, convection oven, and air fryer in a 0.9-cubic-foot countertop design. Its 900-watt microwave output and compact capacity make it a practical option when you want several cooking methods without giving a large appliance most of your counter.
A useful feature is multi-stage cooking: the oven can run up to three functions in one operation. That can simplify a meal that needs to be defrosted, cooked, and crisped in sequence. Preset controls, auto defrost, and a +30 key also help with common tasks.
The stainless steel interior, LED lighting, and included 10.6-inch glass turntable give it a straightforward setup. Its air fry basket and baking/roasting pan are dishwasher-safe, which is helpful after cooking foods that leave grease or crumbs. The smaller capacity is the main tradeoff: it may be less convenient for larger dishes or bigger portions than the West Bend or Breville.
Pros:
- Combines microwave, convection, and air fry functions
- Can run up to three cooking stages in one operation
- Includes a dishwasher-safe air fry basket and baking/roasting pan
- Compact 0.9-cubic-foot capacity can suit a smaller kitchen
Cons:
- Smaller capacity may limit the size of dishes you can cook
- Microwave output is 900 watts, lower than some options here
Verdict: Choose the Sharp if you want three useful cooking modes and multi-stage operation in a smaller countertop oven.
Breville Combi Wave: A Feature-Rich Choice for Flexible Cooking
The Breville Combi Wave brings microwave, convection, and air fry cooking together, with a grill function and additional combination modes. Its 1.1-cubic-foot capacity is larger than the Sharp’s, and its listed microwave input power is 1,200 watts. It is a strong fit if you expect to use more than basic reheating and want several cooking approaches in one appliance.
Its Element IQ system is designed to direct power where it is needed, while the inverter microwave adjusts power intensity for tasks such as reheating and defrosting. The Fast Combi setting combines convection, grilling, and microwave cooking, and Cook From Frozen offers another option for preparing food without thawing it first. The product also includes 19 smart presets and shortcuts for common tasks.
The brushed stainless steel finish and soft-close door add to its polished, quieter-use design. It comes with a Combi Crisp Pan and trivet. The tradeoff is that its many modes and controls may take more time to learn than a simpler microwave. Its capacity is also not the largest in this group.
Pros:
- Combines microwave, convection, air fry, and grill functions
- Inverter microwave power is designed for more even heating and defrosting
- Includes 19 smart presets, shortcuts, and Cook From Frozen
- Soft-close door and mute option help reduce noise
Cons:
- Numerous settings may take time to learn
- Its 1.1-cubic-foot capacity is smaller than the West Bend’s
Verdict: The Breville is a good match if you want a wide range of cooking modes and helpful automatic settings in a mid-size oven.
West Bend 3-in-1: The Largest-Capacity Option Here
The West Bend is a 1.3-cubic-foot microwave, air fryer, and convection oven. That is the largest stated capacity among these five options, which may make it easier to handle family portions or larger dishes than a compact model. The product title lists 1,000 watts, and the controls include 10 power levels and 12 presets.
Its cooking modes cover common uses such as air frying fries or chicken nuggets, baking cookies or brownies, and roasting meat or potatoes. The feature list is more direct than the Breville’s: it focuses on the three core functions rather than describing a long set of combination modes or specialized technologies.
The supplied product data marks this model as unavailable, so check the listing before making it your first choice. It also does not specify included accessories or detailed dimensions, making it harder to assess counter fit and setup from the available information alone. Compared with the Sharp, it offers more capacity; compared with the Breville, it has fewer described cooking features.
Pros:
- Largest stated capacity in this comparison at 1.3 cubic feet
- Combines microwave, air fry, and convection cooking
- Offers 10 power levels and 12 presets
- Listed at 1,000 watts in the product title
Cons:
- Marked unavailable in the supplied product data; confirm listing status
- Available details do not specify dimensions or included accessories
Verdict: Consider the West Bend if its larger capacity is your priority, but verify availability and check the listing for the details you need before choosing it.
TOSHIBA OptiChef Classic: A Versatile Model with Smart Cooking Features
The TOSHIBA OptiChef Classic combines a microwave, air fryer, convection oven, and broiler in a 1.0-cubic-foot countertop appliance. The product details list a 1,000-watt microwave and a compact footprint, with specified clearances for countertop installation. Its four cooking functions make it one of the more versatile options in this lineup.
For everyday cooking, it has 27 auto menus, a smart humidity sensor, and a Smart Combi mode that combines microwave power with convection or broiling. Origin Inverter Technology is designed to provide continuous microwave power. The included accessories are extensive: an air fry basket, baking tray, two wire racks, and a crumb tray.
The stainless steel exterior and interior are intended to make the unit easier to maintain, and the air fry basket is dishwasher-safe. The tradeoff is that shoppers need to account for the listed ventilation clearances as well as the oven’s footprint. Its many programs may also be more than you need if you mainly reheat food and use only one additional cooking mode.
Pros:
- Offers microwave, air fry, convection, and broil functions
- Includes 27 auto menus and a smart humidity sensor
- Comes with an air fry basket, baking tray, two racks, and crumb tray
- Lists specific countertop clearance requirements
Cons:
- Requires the listed side, top, and rear clearances for airflow
- Its range of modes and menus may feel unnecessary for basic reheating
Verdict: The TOSHIBA is a strong option if you want four cooking methods, numerous presets, and a broad set of included accessories.
GE 4-in-1: A Straightforward Choice for Everyday Cooking
This GE countertop microwave combines microwave cooking with air frying, convection, and broiling. It has a 1.0-cubic-foot capacity and 1,050 watts of cooking power. Its functions cover everyday reheating as well as crisping, baking, and browning smaller dishes.
The included accessories help match each cooking method: a stainless steel crisper pan for air frying, a tall rack for broiling, and a short rack for convection cooking. Pizza and popcorn controls keep common microwave tasks simple, while a child lock can be disabled when it is not needed. The product details also describe quiet operation, which may be useful in shared spaces.
The supplied product data marks the GE as unavailable, so confirm that the listing is active before planning a purchase. Its 1.0-cubic-foot capacity is moderate, and the specified ventilation clearances mean it needs room around the sides and top. Unlike the TOSHIBA, the listed GE details do not include a humidity sensor or a large menu of auto programs.
Pros:
- Combines microwave, air fry, convection, and broil functions
- Includes a crisper pan and two racks for different cooking modes
- Offers 1,050 watts of cooking power and a 1.0-cubic-foot capacity
- Has a child lock and everyday convenience controls
Cons:
- Marked unavailable in the supplied product data; confirm listing status
- Requires open space around the unit for proper airflow
Verdict: The GE is worth considering for its four cooking functions and practical included accessories, provided it is available and your counter meets its clearance requirements.
How to Choose an All-in-One Microwave Convection Oven
Match Capacity to Your Meals
Capacity affects the size of dishes and portions you can fit inside. A smaller oven like the 0.9-cubic-foot Sharp can be a reasonable fit for a compact kitchen or simpler meals. The West Bend has the largest listed capacity at 1.3 cubic feet. Check the interior dimensions and turntable size on the product listing if you regularly cook in a particular baking dish, since capacity alone does not show exactly what will fit.
Choose the Cooking Modes You Will Use
All-in-one models can include different combinations of microwave, convection, air fry, and broil functions. Think about the foods you make most often. Air frying can help crisp foods, while convection is useful for baking and roasting. A broil function adds another way to brown or finish dishes. More modes can be helpful, but they are not worth prioritizing if you will rarely use them.
Compare Controls and Automatic Programs
Presets can make common tasks easier, while manual controls give you more direct control over time and power. Consider whether you prefer a short list of basic settings or a larger selection of menus and combination programs. The Sharp offers multi-stage cooking, the Breville has smart presets and specialized modes, and the TOSHIBA lists 27 auto menus. Compare the controls with the way you actually cook rather than choosing by feature count alone.
Check Power and Cooking Details
Microwave wattage is one factor in how quickly the microwave function cooks, but it does not tell the whole story about an oven’s performance. Compare the listed microwave power and look for details about convection, air fry, and combination modes. The Breville lists separate input power figures for microwave, convection, and grill functions, while other models provide fewer power details in the supplied information.
Measure Your Counter and Allow for Airflow
Before buying, measure the space where the oven will sit, including the room needed to open the door and reach controls. Follow the manufacturer’s clearance requirements rather than measuring only the appliance body. The TOSHIBA and GE listings provide specific airflow clearances, so make sure your counter can accommodate those spaces.
Look at Accessories and Cleanup
Included pans, trays, and racks can make it easier to use multiple cooking modes without buying extra pieces. Also check which accessories are dishwasher-safe and whether the interior is designed for easier cleanup. For example, the Sharp lists a dishwasher-safe air fry basket and baking/roasting pan, while the TOSHIBA includes several racks, a tray, and a crumb tray.
Consider How Many Functions You Need in One Appliance
These ovens can reduce the need for separate countertop appliances, but combining several functions does not remove the need to learn each mode and use its correct accessory. If you mainly reheat food, a simpler model may be easier to operate. If you regularly air fry, bake, roast, or broil, a more feature-rich option may make better use of your counter space.
Frequently Asked Questions
What does an all-in-one microwave convection oven do?
It combines microwave cooking with one or more additional cooking methods, such as convection baking, air frying, or broiling. The exact functions vary by model, so check the product details before buying.
Can a convection microwave also air fry?
Some models can. The Sharp, Breville, West Bend, TOSHIBA, and GE options in this comparison all list an air fry function. Accessories and controls differ, so check what each oven includes and how its air fry mode works.
Is a larger capacity always better?
Not necessarily. A larger cavity may give you more room for dishes or portions, but it also needs space on your counter. Choose a capacity that suits your usual meals and available kitchen space.
Do all models include the same accessories?
No. Included items vary. The Sharp lists an air fry basket and baking/roasting pan, while the Breville includes a Combi Crisp Pan and trivet. The TOSHIBA and GE list multiple trays or racks. Confirm the included accessories on the product listing.
Can these appliances replace a full-size oven?
They can handle many smaller cooking tasks, but their capacity is limited compared with a full-size oven. Consider the size of your usual meals and dishes before relying on a countertop model as your main oven.
How much space should I leave around the appliance?
Clearance requirements vary by model. Follow the manufacturer’s instructions for side, top, and rear spacing, and keep the appliance’s vents unobstructed. The TOSHIBA and GE listings provide specific clearance guidance.
Final Recommendation
For a compact appliance with three cooking modes and multi-stage cooking, the Sharp SMC0985KS is a practical pick. The Breville Combi Wave offers a broader set of programs and cooking options, while the TOSHIBA stands out for its four functions and extensive included accessories. If capacity is your main concern, compare the West Bend’s larger stated size with your available counter space. Confirm current listing availability and clearances before choosing any model.
