Wash the potatoes thoroughly under running water to remove any dirt. Pat them dry with a paper towel.
Prick each potato several times with a fork to allow steam to escape during cooking.
In a bowl, coat the potatoes with olive oil, salt, and black pepper. Ensure each potato is evenly covered.
Preheat the air fryer to 400°F (200°C) for about 5 minutes.
Once preheated, place the potatoes in the air fryer basket, ensuring they are not overcrowded.
Cook the potatoes at 400°F (200°C) for 35 minutes, turning them halfway through for even cooking.
After 35 minutes, check if the potatoes are tender by inserting a fork into the center. If they are soft, remove them from the air fryer.
Allow the potatoes to cool for a few minutes. Cut them open and fluff the insides with a fork.
Add your favorite toppings, such as sour cream, chives, cheese, or bacon bits, to taste.
