Overview
Eleven cooking functions live inside the Cosori CAF-R121-SUS, an air fryer oven with a 13-quart stainless steel interior built to combine frying, rotisserie, toasting, baking, roasting and reheating in one countertop unit.
The interior fits two racks so you can cook on two levels at once, useful for family-sized meals rather than single portions. Cosori pairs the oven with 30-plus recipes and includes six accessories, including a rotisserie attachment. The company states it cooks about 40% faster than a traditional oven based on its own testing across a range of foods, a claim not independently verified here.
- 13-quart interior, stainless steel housing
- 11 cooking functions including rotisserie and proof
- Two-level cooking racks for larger batches
- 30+ recipes and 6 accessories included
Who it's for
Fits anyone replacing a separate toaster oven and air fryer with one countertop unit, especially small households cooking for one or two who still want two-rack capacity for bigger batches. Kitchens with limited counter space that need a full-size wall oven substitute may find the footprint still sizable at over 13 inches on each side.
What buyers say
From Amazon customer reviews.
Reviewers consistently point to the warranty as unusually strong for a small appliance and say every function they've tried, toast, bake, air fry, reheat, has performed evenly after months of near-daily use. A couple of buyers had to adjust bake settings or foil coverage to stop the top from over-browning.
Strengths and trade-offs
Drawn from this product's published specifications.
- 11 functions replace several separate countertop appliances
- Two racks allow cooking on two levels at once
- Long warranty for the appliance category
- Reheats leftovers without leaving them soggy
- Takes up meaningful counter or cabinet space
- Rotisserie attachment adds another part to store
- Manufacturer's speed claim is based on its own testing
Performance notes
Preheating is optional and reviewers describe it as fast enough that skipping it makes little practical difference; the two-rack layout lets food closer to the top brown faster than food on the lower rack, so swapping rack positions partway through can even out results. The toast function is reported to brown bread in well under a minute once the unit is up to temperature.
