Scrub the potatoes and dry them well. Prick each one a few times with a fork, rub with olive oil, and season with about 1/2 teaspoon kosher salt.
02 -
Preheat the air fryer to 400°F. Arrange the potatoes in the basket with space between them and cook for 35-45 minutes, turning halfway, until a knife slides easily into the center.
03 -
Let the potatoes cool for 10 minutes. Slice each potato in half lengthwise and scoop the flesh into a bowl, leaving about 1/4 inch of potato inside each skin.
04 -
Mash the potato flesh with butter, sour cream, cream cheese, 2 tablespoons milk, seasoned salt, black pepper, and the remaining kosher salt. Stir in 3/4 cup cheddar, bacon, and green onions. Add more milk only if the filling feels too stiff.
05 -
Spoon the filling back into the potato skins, mounding it slightly. Sprinkle the remaining 1/4 cup cheddar over the tops.
06 -
Air fry the filled potatoes at 350°F for 8-10 minutes, until the centers are hot and the cheese is melted. Garnish with extra green onions and serve warm.
