Scrub potatoes clean, poke several times with a fork, and air fry at 400°F for 35-40 minutes until tender. Let cool for 10 minutes.
Cut potatoes in half lengthwise and scoop out most of the flesh, leaving about 1/4 inch of potato on the skin. Brush insides and outsides with olive oil and season with salt and pepper.
Place potato skins cut-side up in air fryer basket and air fry at 400°F for 5 minutes until edges start crisping.
Fill each potato skin with shredded cheddar cheese and crumbled bacon.
Air fry at 350°F for 3-4 minutes until cheese is melted and bubbly. Top with sour cream and green onions before serving.
