If there are lots of crispy chips, or even scraps, mixed in with your chips then you'll want to place some baking paper in the bottom of your air fryer basket first.
Place a single layer of chips in your air fryer basket.
You won't need any additional oil for this recipe because the chips are already fried so they will have lots of grease and this will heat back up and help the chips crisp up beautifully.
Air fry at 190C (375F approx) for 5-6 minutes. Shake once during the cooking time.
If you like extra crispy chips then you'll want to go for 8-10 minutes of cooking time instead, so an extra 3-4 minutes on the initial cooking time.
Sprinkle the chips with a little extra salt as you're serving them if you like.
Serve and enjoy right away while they are piping hot.
