Preheat your air fryer to 400°F (200°C).
Wash and thoroughly dry the sweet potatoes.
Using a fork, poke several holes all around each potato.
Rub the potatoes evenly with the oil.
Sprinkle salt over the skins.
Place the potatoes in the air fryer basket, leaving space between them.
Cook the Air Fryer Sweet Potato for 35–40 minutes, flipping halfway through if desired.
The potatoes are done when the skins are crispy, caramelization appears around the fork holes, and a knife slides easily into the center.
Carefully remove from the air fryer.
Slice open, fluff the inside with a fork, and serve warm with your favorite toppings.
