Scrub the potato well (there is no need to peel the potato.)
Using a mandoline or a vegetable peeler, thinly slice the potato about 1/16” thick.
Soak the potato slices in a bowl of ice water for 10 minutes to remove the starch. Drain the water from the bowl, then refill it with cold water. Mix with your hands to clean the chips and drain once more.
Place the potatoes in a single layer on a tea towel or paper towels. Pat very dry with another towel.
Add the dry potato slices to a large mixing bowl. Spray the potatoes all over with the olive oil spray and sprinkle with ¼ teaspoon of salt. Toss well to combine. Repeat and spray all over with olive oil spray once again and sprinkle with the remaining ¼ teaspoon of salt.
Working in batches, arrange the potato slices in an even layer in an air fryer basket. (You will be cooking in 2-3 batches, so don’t try to fit them all in at once).
Set the air fryer to 325°F.
Cook, opening the basket to toss, flip, and redistribute all of the chips every 5 minutes. After 15 minutes, remove any chips that are golden brown and crispy. Continue cooking in 2 minute increments until all of the chips are golden brown and crispy on most of the chip area.
Transfer to a plate or bowl, and sprinkle with more salt and pepper to taste. Continue with the remaining potato slices. The chips will crisp up more as they cool, so let them sit for 5 minutes before serving.
