Preheat the air fryer to 400°F for 5 minutes. While it’s preheating, prep your potatoes.
Wash and scrub the potatoes then pat them dry with a paper towel. Poke 6-8 holes in each potato with a fork. Spray each potato with cooking spray then top each evenly with salt and pepper.
4 (8-ounce) large russet potatoes, Cooking spray, 2 teaspoons kosher salt, 1 teaspoon black pepper
Arrange the potatoes in your air fryer, being careful not to let them touch. Close the drawer and air fry at 400°F for 40 minutes. Test to make sure the potatoes are fork tender. If your fork doesn’t easily pierce the potato, cook for another 5 minutes until they are cooked all the way. Repeat this process until the potatoes are tender. This time may vary based on the size of your potatoes.
Remove them from the air fryer and carefully slice them open down the middle. Serve them with butter, vegan butter, salt, pepper, sour cream and/or chives. See notes for twice baked potatoes.
