Air Fryer Twice Baked Potatoes with Cheddar

The first time I pulled these from the air fryer, the skin looked ready while the center still fought the fork. That contrast is exactly why I like making twice baked potatoes this way: the first cook softens the russets all the way through, and the second warms the filling while cheddar melts over the top. These air fryer twice baked potatoes have sturdy skins and a soft, creamy middle without heating up the whole kitchen.

Russets make a fluffy filling, and the sour cream, butter, and milk keep it from tasting dry. I mash the potato flesh with some of the cheddar, then save the rest for the top. That split gives you cheesy flavor throughout and a melted layer on each potato half. The air fryer handles both cooks, but the lower temperature for the second pass gives the filling time to heat without rushing the cheese.

Kitchen Note

Mash the scooped potato while it’s still warm enough to soften the butter. It blends in more evenly, so you don’t have to work the filling hard to get it creamy.

The Shell Is More Than a Holder: Leave Enough Potato Behind

Once the potatoes are cooked, it’s tempting to scoop them nearly clean so there’s more room for filling. That makes the halves harder to handle, and the skins can sag or tear when you spoon the mash back in. Leaving about a quarter inch of potato attached gives each shell enough structure to sit neatly in the basket and hold its filling through the second air-fry.

Think of the shell as part of the finished bite, not just a little bowl. A thin cushion of potato between the skin and filling keeps the halves from feeling papery, while still leaving plenty of room for the creamy center. Scoop slowly with a spoon and work around the edges before lifting out the middle. If a small patch breaks, set that half snugly against another one in the basket; the filling and its neighbors help keep it in place.

This is also why russets are such a good fit. Their dry, fluffy flesh separates from the skin readily, so you can make a clean cavity without having to scrape aggressively. The goal isn’t a perfectly smooth, hollow shell. It’s an intact half with enough potato left to eat along with the filling.

Why Russets Keep the Filling Fluffy Instead of Dense

Russet potatoes — Their starchy, fluffy texture mashes into a light filling rather than a tight, waxy one. Choose potatoes with intact skins so the halves are easier to fill. A standard russet is all you need; there’s no advantage to seeking out a specialty variety for this dish.
Sour cream, butter, and milk — Each brings something different: sour cream adds a gentle tang, butter rounds out the potato, and milk loosens the mash. They don’t replace one another cleanly, so keep them in their separate roles. Use ordinary dairy products; premium brands aren’t necessary here.
Sharp cheddar — Its stronger flavor holds up against the potato and sour cream. A block of sharp cheddar that you shred at home tends to melt more smoothly, while a bag of pre-shredded cheddar is a convenient option and still works. The sharper the cheese, the more pronounced its savory bite.
Green onions — Slice them thinly so their fresh, mild onion flavor doesn’t overwhelm a mouthful of filling. They go on after the final air-fry, which keeps their color and crisp edge rather than cooking them down.

Two Air-Fryer Passes, Two Different Jobs

Start with tender russets

Preheat a 6-quart air fryer to 400°F. Scrub the potatoes, dry them well, prick each several times with a fork, then rub them with olive oil and 1/4 teaspoon of the kosher salt. Air-fry for 35 to 45 minutes, turning the potatoes halfway through. They’re ready when a fork slides easily into the centers; if you still meet a firm spot, they need more time.

Scoop out the centers without flattening the skins

Let the potatoes cool until they’re easy to handle, about 10 minutes, then halve them lengthwise. Scoop the flesh into a medium bowl, leaving about 1/4 inch attached to each skin so the halves keep their shape. Take care around the narrow ends, where it’s easiest to push through the skin. Set the shells aside while you make the filling.

Mash a creamy filling, not a paste

Mash the potato flesh with the butter, sour cream, milk, 1/4 cup of the cheddar, the remaining 1/4 teaspoon salt, and the black pepper. Stop when the ingredients are evenly combined and the texture is creamy; working the potato more than needed can make it dense. If the mixture looks a little textured, that’s fine. It doesn’t need to be perfectly smooth to fill well.

Fill the halves and melt the cheddar

Spoon the filling evenly into the shells and sprinkle the remaining cheddar over the tops. Arrange the halves in a single layer in the air fryer basket so the hot air can move around them. Air-fry at 350°F for 6 to 8 minutes, until the filling is hot and the cheese has melted. Finish with the thinly sliced green onions just before serving.

Small Changes That Shift the Cheddar or Onion in Every Bite

Put all the cheddar on top

Instead of mixing some cheddar into the potato, scatter all of it over the filled halves. You’ll get a more distinct layer of melted cheese on top and a simpler, more potato-forward center. The same total amount of cheddar goes into the dish; only where it lands changes.

Carry the green onion through the filling

Fold some of the thinly sliced green onions into the mash and keep the rest for the finish. That spreads their mild bite through the potato instead of keeping all of it on top. Add them to the filling after mashing so they stay distinct rather than getting crushed into it.

Storage and Reheating

Refrigerator: Refrigerate leftovers in an airtight container for 3 to 4 days. The skins soften and the cheese firms up as they chill.
Freezer: Freezing isn’t my first choice; the sour-cream-and-milk filling can turn grainy or watery after thawing.
Reheating: Warm them in the air fryer at 350°F until the filling is hot and the cheese has softened. Keep the halves in a single layer; crowding the basket slows reheating, and the skins won’t regain their texture as well in a microwave.

Questions That Come Up While These Potatoes Cook

Can I use pre-shredded cheddar?+

Yes. It melts in the air fryer, though the anti-caking coating on some packaged cheese can make the result a little less smooth than freshly shredded cheddar. Use sharp cheddar for the same savory, tangy flavor.

Can I leave off the green onions?+

Yes. The potatoes will still have the creamy cheddar filling, but you’ll miss the fresh, lightly sharp finish the onions add. There’s no need to change the air-fryer timing if you omit them.

Can I make these dairy-free?+

Not by simply leaving out the butter, sour cream, milk, and cheddar; they provide the filling’s richness, tang, moisture, and structure. A dairy-free version would need replacement products and adjusted proportions, so I wouldn’t omit the dairy and expect the same filling.

How do I keep the filling from turning gluey?+

Mash just until the dairy and seasonings are incorporated, then stop. Overworking cooked potato releases more starch and can make the texture sticky instead of fluffy. A few small lumps are better than an overmixed filling.

Can I use a smaller air fryer than a 6-quart model?+

Check that the whole potatoes fit without being crammed together during the first cook and that the filled halves fit in a single layer for the second. If they don’t, cook them in batches rather than stacking them; crowded potatoes won’t cook as evenly.
