Preheat the air fryer to 380°F (193°C) for 3–5 minutes. Preheating helps the coating crisp right away.

Add the frozen onion rings in a single layer. Don’t thaw first. Avoid crowding; air needs space to circulate.

Optional: Lightly spray the rings with cooking spray for extra color. Skip if they already look oily.

Air fry for 6–8 minutes, shaking the basket or flipping halfway. Thicker or beer-battered rings may take 8–10 minutes.

Check for doneness. They should be golden brown, crisp on the outside, and hot in the center. Add 1–2 more minutes if needed.

Season immediately with a pinch of salt while hot to help it stick.

Serve right away with your favorite dipping sauces.
