Reheating fries is a different job from cooking it raw: you want the middle steaming without drying the outside. Start at 180°C / 350°F for 3-5 min. Shake once and they crisp back up as if freshly cooked. Only reheat leftovers that were chilled within 2 hours, and only reheat once.
How to reheat fries
- 1If the air fryer is cold, a brief preheat to 180°C / 350°F helps fries crisp instead of sitting in a warming basket.
- 2Spread leftover fries in a single layer. Stacked leftovers stay cold in the middle.
- 3Reheat at 180°C / 350°F for 3-5 min, checking toward the end. Shake once and they crisp back up as if freshly cooked.
- 4Stop when fries is steaming hot throughout. Serve at once; sitting in the basket dries it.
Tips for the best results
- Shake once and they crisp back up as if freshly cooked.
- Use a lower temperature than the original cook so the outside does not catch while the centre warms.
- Chill leftovers promptly. The air fryer cannot make unsafe leftovers safe.
Common mistakes to avoid
- Reheating fries at the original high cook temperature until it dries out.
- Piling leftovers so only the top gets hot.
- Reheating the same batch more than once.
