Heat the air fryer to 400 °F (200 °C) for at least 5 minutes.
Meanwhile, rinse, scrub, and dry the potatoes. Use a fork to prick the potatoes in a few places on both sides of the potatoes.
Rub the potatoes with the olive oil.
Sprinkle on the salt and garlic powder.
Place the potatoes in the basket of your air fryer.
Cook for 25 minutes, rotate with tongs and cook for another 15-20 minutes or until easily pierced with a fork.
Remove the potatoes with oven mitts, slice open and use a fork to fluff the insides.
Add toppings.
If you have leftovers, let them cool completely and then refrigerate (in tupperware or plastic wrap). The best way to get the crispiness back is to put them in the air fryer and reheat at 400℉ for a few minutes until warmed.
Notes
About 200-300 grams each but if yours are larger or smaller, you can just adjust the baking time.
