When a knife slides easily into the center of a russet, the skin has gone taut and the inside is soft enough to scoop. That’s when these air fryer twice baked potatoes start to come together: the shells are sturdy, and the potato goes back in as a buttery, cheddar-filled mound instead of a loose pile. I like that the air fryer handles both cooks without heating the whole oven, but the basket needs room for air to move around the potatoes.
I dry the potatoes carefully before oiling them, then cook them whole until they give easily to a knife. After that, the first high-heat cook is done; the filled halves finish at a lower temperature, just long enough for the cheddar to melt and pick up a few golden spots. That gentler finish keeps the tops from racing ahead while the centers warm. You get soft russet, tangy sour cream, and browned cheddar tucked into a tender skin.
Kitchen Note
Leave about a quarter inch of potato against each skin when you scoop. A thin shell is more likely to split when you fill it, so take a moment to keep that little cushion intact.
Save these air fryer twice baked potatoes for a side with crisp-edged skins, a tangy cheddar filling, and golden tops.
Why the Cheddar Is Split Between the Filling and the Top
Putting cheddar in two places gives these potatoes more than one cheesy note. The portion mashed into the potato seasons the filling throughout, while the cheese on top melts directly against the hot air and turns lightly browned. If all the cheese went inside, you’d lose that distinct golden cap; if it all went on top, the middle would taste less rich and savory.
Sharp cheddar works especially well because its flavor holds up beside the butter and sour cream. The filling also needs to stay thick enough to sit in the shells rather than slump over their edges. Russet potato absorbs the dairy as you mash, so the mixture comes together without needing a sauce or another binder. Keep the texture soft and spoonable, not loose or whipped; these halves only spend a few minutes in the air fryer after they’re filled.
Why Russets and Sharp Cheddar Make the Most Reliable Base
- Russet potatoes — Their fluffy interior mashes smoothly, and their skins hold up when scooped and refilled. Choose potatoes close in size so they cook at a similar pace; medium russets around the listed size are a better fit than a mix of tiny and oversized ones.
- Olive oil — A thin coating helps the potato skins cook in the air fryer. A basic olive oil is fine here; the useful prep detail is drying the scrubbed potatoes well before rubbing them with oil.
- Butter, sour cream, and milk — Butter brings richness, sour cream gives the filling its gentle tang, and milk loosens the mash into a spoonable texture. Unsalted butter keeps the seasoning easier to control. For a dairy-free version, use the replacements in the variation below rather than swapping in extra milk alone.
- Sharp cheddar — Its fuller flavor stands up to the potato and sour cream. A standard bag of shredded sharp cheddar works; a good-quality cheddar makes the cheese taste more pronounced, while freshly shredded cheddar tends to melt more evenly.
- Scallions — Thin slices spread a mild onion flavor through the filling without making it taste heavy. Use the green and white parts, and slice them thinly so they mix through the potato instead of clumping.
Getting Tender Centers and a Cheesy Top in Two Air-Fryer Cooks
Prep the Potatoes for Air-Fryer Heat
Preheat a 6-quart air fryer to 400°F for 5 minutes. Scrub the russets, dry them well, prick each one several times with a fork, and rub them with olive oil. Dry skins take the oil more evenly, and the fork holes give steam a way to escape as the potatoes cook.
Cook Until a Knife Slides Through
Arrange the potatoes in a single layer in the basket and cook at 400°F for 35–45 minutes, turning them halfway through. The exact point depends on the potatoes, so use the knife test rather than pulling them out just because the timer has reached the lower end. When a knife slides easily into the center, the flesh is ready to scoop. Work in batches if the potatoes don’t fit without crowding.
Mash a Filling That Holds Its Shape
Let the potatoes cool until they’re comfortable to handle, then slice each one lengthwise and scoop the flesh into a medium bowl. Keep about 1/4 inch of potato in each skin so the shells stay sturdy. Mash the flesh with the butter, sour cream, milk, 3/4 cup of the cheddar, scallions, 1/2 teaspoon of the salt, and black pepper. Stop when the mixture is combined and spoonable; it shouldn’t look runny.
Finish at a Lower Temperature
Spoon the filling back into the potato skins and arrange them in a single layer in the basket. Scatter the remaining 1/4 cup cheddar over the tops. Air fry at 350°F for 5–8 minutes, working in batches if needed, until the cheese is melted and the tops are lightly browned.
Three Small Changes That Give These Potatoes a Different Finish
Make the tops more cheese-forward
Keep the same total cheddar but reserve more of it for the tops and mash less into the filling. The browned layer will be more pronounced, while the potato mixture will taste a little less cheesy throughout.
Keep some scallion flavor fresh
Mix half of the thinly sliced scallions into the filling and scatter the rest over the potatoes just after air frying. You’ll get the same mild onion flavor with a fresher, sharper bite at the finish.
Make the filling dairy-free
Replace the butter with plant-based butter, the sour cream with plain unsweetened dairy-free sour cream, the milk with unsweetened non-dairy milk, and the cheddar with dairy-free cheddar-style shreds, using the same amounts. The filling will be a little less rich, and the cheese topping may melt and brown differently from dairy cheddar.
Storage and Reheating
- Refrigerator: Store leftovers in a covered container for up to 4 days. The skins soften and the filling firms as it chills.
- Freezer: Freeze the filled halves on a tray until firm, then wrap them individually and store for up to 2 months for best quality. The filling may be a little less smooth after thawing.
- Reheating: Warm them in the air fryer at 350°F until hot throughout and the cheese softens. Don’t raise the heat to hurry them; the topping can brown before the center is warm.
