Begin by thoroughly washing and drying the medium Russet or Idaho potatoes. Pierce each potato all over with a fork to allow steam to escape during cooking.

Spray the prepared potatoes with olive oil, then sprinkle kosher salt evenly on the surface. Add black pepper if desired.

Place the seasoned potatoes in the air fryer basket without them touching. Set the air fryer to 400°F and cook for 35-40 minutes, turning halfway through.

After 35 minutes, check the doneness by inserting a knife or fork into the center. If not tender, continue air frying in 2-minute increments.

Once done, remove the potatoes and let them rest for a minute before slicing open and adding your favorite toppings.
