Gather your ingredients, including medium-sized potatoes, olive oil, salt, and any desired toppings like sour cream, cheese, chives, or bacon bits.
Wash and scrub the potatoes thoroughly to remove any dirt. Pat them dry with a paper towel.
Use a fork to poke several holes around each potato. This helps steam escape during cooking and prevents the potatoes from bursting.
Rub each potato with olive oil and sprinkle with salt. You can also add other seasonings like garlic powder, paprika, or rosemary, if desired.
Preheat your air fryer to 400°F (200°C) for about 5 minutes.
Place the potatoes in the air fryer basket in a single layer, ensuring they are not overcrowded. Cook for 35-40 minutes, flipping halfway through cooking, until the potatoes are tender and the skins are crispy.
To check if the potatoes are done, insert a fork or knife into the center of the potato. If it slides in easily, the potatoes are ready.
Remove the potatoes from the air fryer and let them cool for a few minutes. Slice each potato open and fluff the insides with a fork. Serve hot with your favorite toppings.
