Frozen onion rings in the air fryer
Frozen onion rings takes 10 to 16 minutes at 390°F (200°C) in an air fryer straight from frozen, shaken or turned at 7 minutes.
What to know about air frying frozen onion rings
Cosori gives frozen onion rings 390°F for 10 to 16 minutes with a shake. Onion rings are the frozen food most improved by an air fryer, because the failure mode in an oven is the coating going soft as the onion inside releases steam — and a fan removes that steam as it appears. They also stack terribly: rings nest inside each other and the contact faces stay raw.
The mistake people make
Shaking them like fries. A vigorous shake separates the batter from the onion, and once that seal is broken the ring releases steam into its own coating and goes limp. Turn them individually or shake very gently.
How to tell when it's done
Deep, even gold with the coating audibly crisp when tapped. Bite one — the onion inside should be soft and sweet rather than sharp and crunchy, which means the heat has actually reached the middle.
