Preheat your air fryer to 400°F (200°C) for about 5 minutes.

Scrub the medium potatoes under cold water, then pat them dry.

Using a fork, prick each potato several times, then rub with oil and sprinkle with salt and pepper.

Place the seasoned potatoes in the air fryer basket in a single layer. Cook for 35 to 40 minutes, flipping halfway through.

Check the potatoes for doneness. They should feel tender when pierced and have a crispy skin.

Remove the potatoes from the basket and let them cool slightly for 5 minutes before serving with your favorite toppings.
