Start by washing the Russet potatoes under cool running water. Use a vegetable brush to scrub away any dirt or debris. Pat them dry with a clean kitchen towel.
Using a sharp knife or a fork, carefully prick each potato several times. This allows steam to escape during cooking, preventing them from bursting.
In a mixing bowl, combine the potatoes with olive oil and salt. Make sure each potato is evenly coated. This step is crucial for achieving that golden, crispy skin.
Preheat your air fryer to 400°F (200°C) for about 5 minutes. This ensures that the potatoes start cooking immediately upon being placed inside.
Place the seasoned potatoes in the air fryer basket, making sure they are not overcrowded. Cook at 400°F (200°C) for about 35-40 minutes, turning them halfway through the cooking time for even crisping.
After 35 minutes, check the potatoes by inserting a fork or skewer. If it goes in easily, they are done. If not, continue cooking for an additional 5 minutes.
Once cooked, carefully remove the potatoes from the air fryer. Allow them to cool slightly before slicing open and adding your favorite toppings. Enjoy your fluffy, crispy Air Fryer Baked Potatoes!
