Using a mandolin thinly slice the potatoes. You can also slice the potatoes by hand, just make sure they are thin. Soak the potatoes in cold water with ice for 15 minutes and then drain. Pat dry with a paper towel.
Spray the bottom of your air fryer with the olive oil spray. Lay the potatoes in an even layer in the air fryer so they aren't overlapping. Spray the top with the olive oil spray and then sprinkle with salt.
Cook at 360 degrees for 10-15 minutes. Check your potatoes after 5 minutes and stir every 5 minutes until they are golden brown. Garnish with parsley and sprinkle with more salt if needed.
