- 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.
