Toppings of choice: butternonfat plain Greek yogurt (or sour cream), chopped fresh chives, cooked and crumbled bacon*
Scrub and dry the potatoes. Rub evenly with the oil and sprinkle with salt. Pierce all over with a fork.
Turn the air fryer to 400 degrees F. Add the potatoes in a single layer (do not let them touch or the skins will not crisp). Air fry the potatoes for 25 minutes. With tongs, carefully flip the potatoes over.
Return the potatoes to the air fryer. Continue air frying for 10 to 25 minutes more, until the potatoes pierce easily with a fork (the total time will vary based upon the size of your potatoes). Remove to a plate.
Once cool enough to handle, use a sharp knife to slit the potatoes lengthwise down the center and gently squeeze the sides to open. Add toppings of choice. Serve hot.
