Preheat the air fryer to 400°F (200°C).
Place the fries in the basket, being careful not to overfill it.
Heat the curly fries for 4-5 minutes.
Give the basket a shake after a couple of minutes to allow all the fries to get maximum exposure to the hot air.
If you have a lot of curly fries to reheat, you’ll need to work in batches.
Don’t stuff too many in the basket at once, or they won’t crisp up evenly.
Check on the fries frequently because they can go from just right to overcooked and dry very quickly.
