Air Fryer Twice Baked Potatoes are my go-to when I want a side dish that looks like it took all day but comes together without the fuss. Crispy russet skins are loaded with a buttery, creamy mash of sour cream, mayo, sharp cheddar, and green onions, then finished with more melted cheese and crispy onions on top. I make them for holiday tables, game day spreads, and potlucks because they travel beautifully and everyone always goes back for seconds. Leftovers keep in the fridge for up to 4 days and reheat beautifully in the air fryer.
Scrub the potatoes and get them clean. Place the potatoes in the air fryer basket and bake at 400°F (200°C) for 30 minutes. Let them cool. Once cool, cut in half lengthwise, creating boat-shaped halves.
6-8 small/medium russet potatoes
Scoop out the insides into a medium bowl and place the skins on the air fryer basket.
Mash the potatoes with a fork. Add the butter, sour cream, mayonnaise, egg, green onions, 1 cup of cheese, salt and pepper. Mix until fully incorporated.
¼ cup butter, ¼ cup sour cream, ¼ cup mayonnaise, 1 egg, 1 teaspoon green onions, 2 cups shredded Cheddar cheese, Salt and ground black pepper
Spoon the mixture into the potato skins (you may have more skins than filling). Sprinkle the remaining cheese over the potatoes. Bake again in the air fryer at 350°F (180°C) for about 15 minutes, or until heated through and golden on top.
Garnish with crispy onions. Serve and enjoy!

Notes
Here are a few tips I've picked up from making these more times than I can count.
Scrub the skins well: The potato skins are part of the dish, so take a minute to scrub them thoroughly before air-frying. Clean skins also hold up better when scooping.
Leave enough flesh when scooping: Don't hollow out the skins too aggressively. Leaving a thin layer of potato along the edges keeps the skins sturdy and prevents them from collapsing under the filling.
Mash the filling thoroughly: The smoother the filling, the creamier the final result. Take your time mashing before adding the other ingredients, or use a hand mixer for the fluffiest texture.
Don't overfill the skins: Spoon the filling in generously, but not so high that it spills over the edges in the air fryer. A slightly mounded top works great and crisps up nicely.
Add the crispy onions right before serving: If you're making these ahead or transporting them, hold off on the crispy onion garnish until just before serving so they stay crunchy rather than get soggy.
Flash-freeze before storing: If you're freezing a batch, spread the filled potatoes on a baking sheet and freeze them uncovered for about an hour, then transfer them to a freezer bag. They won't stick together, and they'll keep their shape perfectly.
