Preheat the air fryer to 380 degrees F (190 C) for 3 minutes. Rub the potatoes lightly with olive oil and pierce a few times top and bottom with a fork.

Bake the potatoes for 35-40 minutes, flipping halfway to ensure they cook evenly. They're done when they feel tender when squeezed.

Allow the potatoes to cool. Meanwhile, cook and crumble the bacon (reserving the grease).

Cut the potatoes in half. Scoop out the center of the potato, leaving about 1/4" all around.

Coat the potatoes with the reserved bacon grease. Salt and pepper the inside of the potato. Add the potatoes in a single layer to the air fryer basket. Cook for 10 minutes at 400 degrees F (200 C). Flip them over halfway through.

After 10 minutes, open the basket and add the cheese in the center of each potato.Cook for 3 minutes, until the cheese is melted.

Transfer the potato skins to a plate and top with the bacon bits and green onions. Serve right away with additional toppings, if desired.
