How We Tested the Cosori Air Fryer Toaster Oven
Our culinary team consulted with professional chefs and cross-referenced our hands-on stress tests with long-term user feedback to verify durability claims. We ran this oven through over 40 cooking cycles — air frying, baking, roasting, broiling, dehydrating, and rotisserie — across a full month of daily use. We measured temperature accuracy with an infrared thermometer, tested the nonstick interior with sticky marinades, and even dropped a frozen pizza on the rack to see if it would bend. Every claim here comes from real kitchen time, not spec sheets.

Cosori 11-in-1 Air Fryer Oven (Versatile Countertop Workhorse)
Here’s the deal: This is the one countertop oven that actually delivers on its 11-function promise without feeling gimmicky. If you want one appliance that can air fry, rotisserie a whole chicken, bake a pizza, and dehydrate fruit — all without heating up your main oven — this is it.
The first thing you notice when you pull it out of the box is the weight. This isn’t a flimsy toaster oven — the 13-quart stainless steel body has a solid heft, and the door closes with a satisfying magnetic click. The interior is roomy enough for an 8-inch pizza or 2 lbs of fries, and the two-level cooking racks let you double up batches. We immediately appreciated the brushed stainless finish — it doesn’t show fingerprints the way some glossy ovens do.
After a month of daily use, the real standout was the rotisserie function. We cooked a 3.5-lb chicken on the spit, and the even heat distribution gave us crispy skin with juicy meat — no rotating required. The air fry mode produced noticeably crispier fries than our old basket-style air fryer, and the dehydrate function turned apple slices into chewy chips in about 6 hours. One honest annoyance: the touchscreen interface can be finicky with wet fingers. You’ll want to dry your hands before pressing the presets.
Pros:
- 11 functions that actually work — Rotisserie, air fry, bake, broil, toast, dehydrate, reheat, pizza, cookies, slow cook, and keep warm. We used all of them; none felt like marketing fluff.
- Large capacity for a countertop oven — The 13-quart interior fits a 4-lb roast or a full sheet of frozen fries. Two-level cooking is a real time-saver.
- Even heat distribution — The rear fan and top heating elements work together to eliminate hot spots. Our cookies baked uniformly across the tray.
- Easy to clean nonstick interior — After a rotisserie chicken, the drippings wiped off with a damp cloth. No scrubbing needed.
Cons:
- Touchscreen can be unresponsive — When your hands are damp from prepping food, the capacitive buttons don’t always register. We had to tap multiple times.
- Noisy fan on air fry mode — It’s louder than our previous toaster oven; you’ll hear it running from the next room.
- No included baking stone — For pizza mode, a stone would improve crust crispness. You’ll need to buy one separately.
Our Take
Great match for: Anyone who wants to replace a toaster oven, air fryer, and rotisserie with one machine — especially if you cook for 2-4 people. Think twice if: You have very limited counter space (it’s 17 inches deep) or you need a silent appliance for an open-concept kitchen.
What to Look for in a Smart Air Fryer Toaster Oven
Before you buy, consider these factors we weighed during our cosori smart air fryer toaster oven reviews testing process.
Capacity and Size
The 13-quart interior of the Cosori is generous, but not every countertop oven fits under standard cabinets. Measure your space — we had to slide ours forward an inch to open the door fully. If you cook for a family of four, look for at least 12 quarts.
Cooking Functions That Matter
Not all 11 functions are created equal. We found the rotisserie, air fry, and dehydrate modes to be the most useful. Toast and reheat are nice bonuses, but don’t buy an oven just for those. Focus on the functions you’ll actually use weekly.
Ease of Cleaning
The nonstick interior on the Cosori is a major plus — we’ve used ovens that required hours of scrubbing. Look for removable crumb trays and dishwasher-safe accessories. The Cosori’s interior wiped clean in under 2 minutes after a messy rotisserie chicken.

Our Final Recommendation
The Cosori 11-in-1 Air Fryer Oven is our top pick for anyone seeking a versatile countertop oven that genuinely replaces multiple appliances. It’s not perfect — the touchscreen can be fussy, and the fan is loud — but for the combination of rotisserie, air fry, and dehydrate functions in one well-built machine, it’s the best we’ve tested. If you’re also exploring other options, our guide to the best toaster oven air fryer combo covers additional models we’ve tested. For bakers, our best toaster oven for baking article might be more relevant. But for all-around cooking, this Cosori is the one to beat.
Frequently Asked Questions
Can the Cosori air fryer oven replace my regular oven?
For most daily cooking — roasting vegetables, baking small pizzas, reheating leftovers — yes. It heats up faster than a full-size oven and uses less energy. But you won’t fit a 9×13 baking dish or a whole turkey. For large batches, you’ll still need your main oven.
How do I clean the Cosori air fryer oven interior?
The nonstick coating makes cleanup straightforward. Wipe the interior with a damp cloth after each use. For baked-on grease, use a non-abrasive sponge with warm soapy water. Avoid steel wool or harsh chemicals — they’ll damage the coating.
Is the Cosori smart air fryer toaster oven worth the price?
Given that it replaces an air fryer, toaster oven, and rotisserie — each costing $50–150 separately — the Cosori offers solid value. The build quality and even cooking justify the premium over cheaper models. If you’re comparing it to the Breville Smart Oven Air Fryer, our Breville Smart Oven Air Fryer Damson Blue guide has the full comparison.
Does the Cosori air fryer oven require preheating?
For air frying and roasting, we recommend a 3-5 minute preheat for best results. The oven reaches 400°F in about 4 minutes — faster than a traditional oven but slower than a basket-style air fryer. For toasting, no preheat is needed.
