Clean and cut the baby potatoes in half. If you have some baby potatoes that are much larger, you can cut them into 3 or 4 pieces so that they’re all relatively equal in size. This way, they can cook evenly.
Season the baby potatoes with dried Italian seasoning, garlic powder, salt, pepper, and half the parmesan. Add the oil and, using your hands, make sure the potatoes are all coated in oil and seasoning.
Preheat the air fryer according to the manufacturer’s instructions (or for about 3 minutes if unsure).
Air fry the seasoned baby potatoes at 380°F (190°C) until they are fully cooked, crispy on the outside, and fluffy on the inside. For the size pictured in this recipe, it took 25 minutes. Shake the air fryer basket after 10 minutes and after 15 minutes to make sure the potatoes move around so that they can air fry evenly. Depending on the size of your potatoes, the total cooking time for this recipe can be anywhere from 18 minutes to 25 minutes.
Toss with the remaining parmesan and, if needed, salt and pepper to taste. Serve them hot and crispy in a large serving bowl, and let your hungry guests or family tuck in!
