Wash the potatoes (scrubbing them well to remove any dirt) and then pat them dry.
Poke holes in the potatoes with a knife or fork and then rub them with oil and season them with salt.
Preheat the air fryer for a few minutes (according to the manufacturer’s instructions or default to 3-4 minutes if unsure).
Add the potatoes and air fry at 390°F (200°C) for about 20 minutes. Then, flip the potatoes and keep cooking them until they are tender (about 15-30 minutes more, depending on the size of the potatoes you’re using). To test if the potatoes are ready, use a fork or knife to pierce the potato. If it pierces easily and it feels tender, then it’s ready. The smaller potatoes you see pictured in the article took a total of about 40 minutes, and the larger ones took 50 minutes.
Once they’re ready, plate them up and serve them with your favorite toppings (like sour cream, shredded cheddar, bacon, and more). The fun is only just beginning!
