Cut potatoes into thin slices using a mandolin slicer or a sharp knife. Place potatoes into a bowl with cold water and soak them for at least 20 minutes.

Drain potatoes of water using a colander. Thoroughly pat them dry using paper towels. The more moisture you remove, the crispier they will get.

Season the potato chips with sea salt and olive oil. Place two layers of potatoes in the air fryer tray and cook for 20 minutes at 200°F.

Toss the potato chips. Turn up the heat to 400°F and cook for an additional 5 minutes.
