Step by step
- 1. Preheat the air fryer to 400°F (205°C) for 2–3 minutes.
- 2. Single layer. Arrange without crowding — air needs to reach every side.
- 3. Cook 35–45 minutes. No flipping needed.
- 4. Check doneness. A skewer slides through the center with zero resistance.
The tip that matters
Size beats the clock: a medium russet lands around 40 minutes, but big bakers can need the full 45.
Times vary — here's why
Air fryers differ in wattage and basket size, so treat 35–45 minutes as a range, not a promise: check early the first time, then note what your machine needed. Quantity matters too — a full basket can add 2–3 minutes, and anything stacked will steam instead of crisp. Converting your own oven recipe instead? Use our air fryer conversion calculator.
