Air Fryer Sweet Potato: Time, Temp & How To

Whole air fryer sweet potatoes are roughly half the time of an oven, with the same caramelized-sugar exterior and fluffy interior. About 25 minutes for a medium one. For sweet potato fries, see the next section — completely different recipe, also great.

Temperature

Cook Time

Oven equivalent: 425°F (218°C) for 45 minutes. Preheat the air fryer for 3 minutes for best results. A light spray of oil helps with browning.

How to air fry sweet potato

Scrub the potato. No need to peel; the skin gets crispy and is delicious.
Pierce all over with a fork (5-6 times per side). This lets steam escape so it doesn't explode.
Rub with 1 teaspoon oil and a pinch of salt.
Preheat the air fryer for 3 minutes at 380°F.
Place potato in the basket. Cook for 25-35 minutes depending on size, flipping halfway.
Test with a fork. If it slides in easily, it's done. If there's resistance, give it 5 more minutes.
Let cool for 3-5 minutes before slicing — they're lava hot inside.

Tips that actually matter

Medium sweet potatoes (about 8 oz) take 25 minutes. Large ones (12-14 oz) take 35-40.
Two potatoes at a time work fine if there's space between them. Three is usually too many.
For sweet potato fries: cut into 1/2-inch strips, toss with 1 tbsp oil + 1/2 tsp salt + paprika, cook at 400°F for 14-16 minutes shaking halfway.
For mashed/baked use, slice open while hot and let steam escape; the texture is fluffier.

Common mistakes

Not piercing. Sealed potatoes can rupture in the basket. Always pierce.
Cooking three or more at once. They don't cook evenly without space.
Pulling too early. A sweet potato that resists the fork at all isn't done. Trust the fork test.
Cooking pre-sliced rounds the same way as whole. Slices need 12-15 minutes max.

Variations

Sweet potato fries (1/2 inch cuts): 400°F, 14-16 minutes, shake at 8 minutes.

Sweet potato rounds (1/2 inch slices): 380°F, 14-16 minutes, flip halfway.
Cubed sweet potato: 380°F, 16-18 minutes, shake twice.
Stuffed sweet potato: cook whole, slice open, top with toppings (chili, black beans, taco fillings).
