You don't have to have free space in the oven to make perfect baked sweet potatoes. Is that a familiar situation? Consider these air fryer sweet potatoes. Because it cooks with super-heated air flowing around food items, the air fryer does the job quickly and efficiently. Sweet potatoes are perfectly cooked in about 40 to 45 minutes with just a quick turn at the halfway point. The air fryer is also an excellent way to bake in hot summer weather when you want to avoid using the large oven. Throw some steaks on the grill and sweet potatoes in the air fryer for a fabulous summer meal with very little effort.

The air fryer is also a good method if you need sweet potatoes for a pie, pudding, or casserole. In that case, you can skip the salt. Just scoop the cooked flesh into a bowl, discard the skins, and mash or purée the sweet potato for your recipe.

The number of sweet potatoes cooked at one time depends on the size of the air fryer and potatoes. Most air fryers can accommodate four small to medium sweet potatoes or two to three large ones. Just make sure there's a little space between them for air and heat circulation.


  • 4 medium sweet potatoes

  • 2 teaspoons olive oil

  • 1 1/2 teaspoons kosher salt

  • 4 teaspoons butter, optional

  • 1 tablespoon fresh chopped parsley (or cilantro or chives), optional

Steps to Make It

  2. Scrub the sweet potatoes and dry them thoroughly. Rub the olive oil over the potatoes and sprinkle them with kosher salt. Use a metal skewer or fork to poke several holes in each sweet potato.

  4. Cook the sweet potatoes, turning them about halfway through the cooking time. They should have very little resistance when pricked with a fork. If the potatoes are still a bit firm, add another 3 to 5 minutes to the timer and check again.

  5. With tongs, remove the baked sweet potatoes to a platter or individual plates. Split the sweet potatoes and add a pat of butter. Garnish with fresh chopped herbs, if desired.

Should I Grease the Air Fryer Basket?

Air fryers have a nonstick surface and since the sweet potatoes are coated with oil, that should be sufficient. If you do decide to grease the basket, brush it with a little oil—never use an aerosol nonstick cooking spray.
