Scrub and wash the potatoes, then pat them dry with a paper towel.
Cut thin slices into the potatoes, making sure not to cut all the way through, leaving about ⅛ inch of potato intact.
In a small mixing bowl, mix together the olive oil, parmesan cheese, garlic powder, salt, and black pepper.
Brush the olive oil mixture onto the potatoes. Take the time to get into between each slice.
Place the potatoes in the air fryer basket, making sure they're not touching each other.
Air fry the potatoes for 20-25 minutes, until they're crispy and cooked through.
Remove the potatoes from the air fryer and garnish with your desired toppings.
