Using a mandoline, slice the potatoes into fries. If you don’t have a mandolin slice the potato into ¼ inch sections.
Next, place the fries in a large bowl and cover with water.
Let the cut potatoes sit in the water for 30 minutes. Drain the water and repeat the soaking process with new water for an additional 30 minutes.
After the full hour of soaking, drain the water, and pat fries dry with a paper towel.
Toss with a couple tablespoons of olive oil, salt and pepper.
Preheat Air Fryer to 375°F if required based on the air fryer model that you have.
Add fries to bottom of air fryer basket, making sure they are in a single layer, with a little room between each one.
Cook for 7 minutes, then shake the basket or flip the fries. Continue to cook for an additional 5-7 minutes until crispy and golden brown.
