A countertop oven can save you from heating a full-size oven, but only if it has enough room and useful cooking modes for the food you make most often. The Oster 10 Function Air Fryer Oven, model 2210052, combines air frying, toasting, baking, roasting, and other presets in a 25-liter countertop design. Its main strengths are its ten functions, three rack positions, and capacity for a 12-inch pizza, while its 20.4-inch depth requires more counter space than a basket-style air fryer. This review helps you decide whether that tradeoff makes sense for your kitchen.
Quick Verdict
Rating: 8/10, recommended with caveats
Best For: Small households and home cooks who want one digital appliance for air frying, toast, pizza, baking, and roasting.
Bottom Line: The Oster offers a useful 25L capacity, ten cooking modes, and flexible rack placement. It is less suitable for very tight counters, buyers who want a compact basket air fryer, or anyone who needs a rotisserie function.

What Is the Oster 10 Function Air Fryer Oven?
The Oster 10 Function Air Fryer Oven is a 1,750-watt countertop appliance that combines a toaster oven with forced-air cooking. Oster identifies it as model 2210052 and lists a 25L interior, which the brand also describes as 26 quarts. It is designed for buyers who want one appliance to handle toast, frozen snacks, pizza, baked dishes, vegetables, and roasts.
Unlike a drawer-style air fryer, this model has a front glass door and multiple rack levels. That layout makes it easier to use pans and racks, check food without pulling out a basket, and cook flatter foods such as pizza or toast. The tradeoff is a larger footprint and more interior surfaces to wipe after greasy foods.
Who Should Buy It?
Best For
- Small households that cook several types of food in one countertop appliance
- Buyers who need room for a 12-inch pizza, toast, a baking pan, or a whole roast
- Home cooks who prefer digital controls and preset cooking modes
Skip If
- Your counter cannot accommodate an appliance that is 20.4 inches deep
- You mainly want a compact basket air fryer for one or two servings
- You need an included rotisserie spit or a dedicated rotisserie mode
Before You Buy: Measure the full counter area, not only the appliance width. The verified depth is 20.4 inches, and you also need the clearance specified in the manual for heat and airflow.
Design and Build Quality
The oven uses a horizontal countertop design with a stainless-steel color and a tempered-glass door. Its 18-inch width is manageable for many kitchens, but the 20.4-inch depth can make it feel closer in size to a small microwave than a compact toaster. Buyers with shallow counters should check that the feet sit fully on the surface and that the door can open without obstruction.
Oster adds heating elements and a perforated interior to improve airflow during air frying. The three rack positions also give you more control over browning. Food placed high in the oven cooks closer to the upper heating elements, while lower positions provide more space for taller dishes.
Ten Cooking Functions and Digital Controls
The ten modes are air fry, bake, broil, defrost, dehydrate, pizza, roast, TenderRoast, toast, and warm. That set covers more daily tasks than a basic air fryer, especially when you need a low-temperature mode, a toast setting, or a dedicated pizza program.
The digital display and touch controls make the front panel cleaner than a multi-dial design. Presets can reduce setup time, but you should still check food early when adapting a recipe from a full-size oven. Countertop ovens have smaller cavities and place food closer to the heating elements, so browning can happen sooner.
TenderRoast for Slow, Gentle Cooking
TenderRoast is Oster’s low-temperature roasting mode for meat, poultry, pork, and seafood. It gives this model a useful point of difference from ovens focused only on fast air frying. It is best for buyers who want both quick crisping and slower roasting in the same appliance.
Air Fry Performance and Oil Use
Air fry mode circulates hot air around food while the added heating elements and perforated interior support browning. Oster states that the mode can deliver a crispy finish with 99.5% less oil than traditional deep frying. That comparison describes oil use, not the nutrition of every recipe, so ingredients and portion size still matter.
For better results, spread food in a single layer on the mesh rack and leave space between pieces. Crowding blocks airflow and can produce pale or uneven areas. Turning or shaking food partway through cooking may also help, especially with fries, vegetables, and breaded snacks.
Capacity and Rack Flexibility
The 25L interior can fit a 12-inch pizza or a whole roast. This makes the Oster more practical for family-size snacks, toast, and flat foods than a small drawer air fryer. The three rack positions let you choose the right distance from the heating elements and create room for taller food.
Although Oster says the rack levels can support cooking more than one food at once, results depend on the foods, temperatures, and airflow needs. Two trays can also slow cooking or brown unevenly. For best results, pair foods with similar time and temperature needs, then rotate positions if the manual or recipe recommends it.
Included Accessories and Cleaning
The verified package includes a baking pan, crumb tray, wire rack, and air fryer mesh rack. The baking pan handles drips and baked foods, the mesh rack supports airflow, and the removable crumb tray catches loose crumbs below the cooking area. The official list does not show a rotisserie spit.
Cleaning is easier when you remove crumbs and grease before they build up. Let the oven cool, remove the accessories, and follow Oster’s care instructions for each part. Because the current product pages do not clearly confirm that every accessory is dishwasher safe, hand washing is the cautious choice unless the manual states otherwise.
How It Performs in Real Use
For Weeknight Air Frying
The mesh rack and wide oven cavity work well for foods that benefit from a broad single layer, such as wings, vegetables, fries, and frozen snacks. You get more visible cooking space than in a deep basket, but you may need to turn food and clean grease from the pan or crumb tray afterward.
For Pizza, Toast, and Reheating
A 12-inch pizza fit is useful for frozen pizza, flatbreads, and reheating slices without making the crust soft. Toast and warm modes also make this appliance more practical as an everyday toaster-oven replacement. Results can vary by rack level, so note the position that works best for your preferred browning.
For Baking and Roasting
The 1,750-watt output and 25L cavity can handle small baked dishes and a whole roast without heating a full-size oven. The front glass door helps you monitor browning, but opening it repeatedly releases heat. Use the baking pan for drips and verify doneness with a food thermometer when cooking meat or poultry.
For Dehydrating and Meal Prep
Dehydrate mode adds value for buyers who make dried fruit, vegetables, herbs, or small batches of snacks. Dehydrating takes longer than air frying, so this use case makes the most sense when you are comfortable leaving counter space committed to one task for several hours while following the manual’s safety guidance.
Setup Tips Before First Use
- Remove all packaging and wash the removable accessories according to the manual before cooking food.
- Place the oven on a stable, heat-resistant surface with the required clearance around its vents.
- Confirm the crumb tray is installed in the correct position before use.
- Use the rack level recommended for the selected function and food thickness.
- Start checking food before the end of a full-size-oven recipe time because countertop cooking can brown faster.
- Keep the mesh rack and perforated interior clear enough for air to circulate.
Pro Tip: Put the baking pan on a lower level beneath the mesh rack when cooking foods that release grease, as long as that placement matches the manual. It can catch drips without wrapping or covering the air fry rack.
Food and Electrical Safety
This is a 1,750-watt heating appliance, so follow the manual’s outlet, clearance, and ventilation instructions. Keep the oven away from water, do not block vents, and avoid placing paper, plastic, or other non-oven-safe materials inside. The glass door, metal housing, racks, and pans can remain hot after cooking.
Aluminum foil should never block airflow or contact heating elements. Use it only in a way allowed by the Oster manual, and do not line the crumb tray or perforated surfaces unless the instructions specifically permit it. For meat, poultry, and seafood, use a food thermometer and follow current food-safety temperature guidance.
Pros and Cons
Pros
- Ten verified modes cover air frying, baking, toast, pizza, roasting, dehydrating, and warming
- 25L capacity fits a 12-inch pizza or whole roast
- Three rack levels improve positioning flexibility
- Digital controls provide a clean interface with preset functions
- Four included accessories support baking, air frying, and easier crumb collection
Cons
- The 20.4-inch depth may be too large for shallow counters
- No rotisserie spit is included in the verified accessory list
- Multi-level cooking may require tray rotation and extra monitoring
Is It Worth the Price?
The Oster fits the mid-range feature tier because it combines a 25L oven cavity, digital controls, ten cooking modes, and four accessories. It offers strong value for the price when you will regularly use several functions and want to reduce reliance on a full-size oven.
It is less compelling if you mainly air fry small portions or already own a capable toaster oven. In that case, a compact basket air fryer may take up less usable counter space and require less interior cleaning. Value also depends on current availability, so compare the live offer with other 18L to 25L air fryer ovens before buying.
How It Compares to Alternatives
The Ninja Flip Toaster Oven & Air Fryer is worth comparing when storage space is your top concern because its body flips up against the backsplash when not in use. The Oster makes more sense when you prefer its 25L capacity, three rack positions, and TenderRoast mode.
The Instant Pot Omni Plus 18L is a better comparison for buyers who specifically want rotisserie cooking because it includes rotisserie hardware and a rotisserie function. The Oster has a larger stated capacity, but it should not be purchased with the expectation that a rotisserie spit is included.
Frequently Asked Questions
Is this a basket air fryer or an air fryer toaster oven?
It is a countertop air fryer toaster oven with a front glass door and rack-style accessories. It offers more space for pizza, toast, pans, and roasts than a small basket, but it has a larger footprint.
What are the ten cooking functions?
The verified modes are air fry, bake, broil, defrost, dehydrate, pizza, roast, TenderRoast, toast, and warm. TenderRoast is the low-temperature roasting option.
Can it fit a 12-inch pizza?
Yes. Oster states that the 25L, or 26-quart, interior can hold a 12-inch pizza or a whole roast. Pan shape and rim size can still affect fit, so check your cookware before use.
Does it include a rotisserie spit?
No rotisserie spit appears in the official accessory list for model 2210052. The confirmed accessories are a baking pan, crumb tray, wire rack, and air fryer mesh rack.
Can you use aluminum foil in this oven?
Use foil only as permitted by the Oster manual. It must not block the perforated interior, restrict airflow, cover vents, or contact heating elements.
Are the accessories dishwasher safe?
The current product pages confirm the four accessories but do not clearly state that every piece is dishwasher safe. Follow the model manual, and hand wash when the care instruction is uncertain.
What is the warranty period?
The current listing directs buyers to separate warranty information but does not clearly state a model-specific term on the product page. Review the warranty document linked by the seller or manufacturer before purchase.
Who should skip this Oster oven?
Skip it if you have a shallow counter, want a small drawer air fryer, or need rotisserie hardware. It is better suited to buyers who will use its oven-style capacity and several cooking modes.
The Bottom Line
The Oster 10 Function Air Fryer Oven is a practical choice for buyers who want a 25L digital countertop oven with air frying, toast, pizza, baking, roasting, and dehydrating modes. Its strongest advantages are its versatile function set, three rack levels, and 12-inch pizza capacity, while its deep footprint and lack of rotisserie hardware are the main reasons to skip it.
