Loaded baked potato skins are a crowd-pleasing appetizer that can be easily made in an air fryer. Start by cutting the potatoes in half lengthwise and scooping out the flesh, leaving a thin layer of potato on the skin. Brush the potato skins with melted butter and sprinkle them with salt and pepper. Place the potato skins in the air fryer basket and cook at 400°F for about 10 minutes, or until they are crispy. Remove the potato skins from the air fryer and fill them with shredded cheese, bacon bits, and green onions. Return them to the air fryer for another 2-3 minutes, or until the cheese is melted and bubbly. Serve with sour cream on the side.
