Put potato peels into the air fryer basket. Spritz them with oil and sprinkle with a pinch of salt.
Air fry at 400 degrees for 6 to 8 minutes. Stop once about halfway through to shake the basket and give the peels another spritz of oil. Check on them during the last few minutes of cooking to make sure they get brown and crisp, but not burned.
Serve right away with any of the optional toppings, if desired.
The peels shrink when they cook. So be careful not to over salt them.
The air fryer works best when it’s not overcrowded. So if you have considerably more peels than called for in this recipe, air fry in batches for best results. However, once the air fryer is hot, the peels will likely cook faster too.
