How to make it

  1. Set the air fryer to 390°F (200°C). A 2–3 minute preheat is optional but helps browning.
  2. Cook for 6–9 minutes. No flipping needed.
  3. Start checking at the 6-minute mark — air fryer models vary quite a bit.

Tip: Thin spears take 6 minutes, thick ones 9. Trim the woody ends first.

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.
