How to make it

  1. Set the air fryer to 400°F (205°C). A 2–3 minute preheat is optional but helps browning.
  2. Cook for 8–10 minutes. Flip halfway through cooking.
  3. Start checking at the 8-minute mark — air fryer models vary quite a bit.

Tip: Single layer — stacking makes them steam instead of crisp.

Times assume a standard 1500–1800W basket air fryer. Compact or very full baskets can need 2–3 extra minutes; large oven-style units often finish a bit sooner.

Cooking from an oven recipe instead? The conversion calculator turns any oven temperature and time into air fryer settings.
