Preheat the air fryer to 380°F for 5 minutes. Peel the sweet potatoes, then slice each potato into even ¼-inch-thick sticks.
Season:
Place the sweet potatoes in a large mixing bowl and toss with olive oil, salt, garlic powder, paprika, and black pepper.
Cook:
Place the sweet potato fries in the air fryer basket, in a single layer. Depending on the size of your air fryer, you might need to cook in 2 batches.
Cook at 380F for 12 to 15 minutes, opening the air fryer around minute 8 to shake the fries and turn them. When the outsides are crispy and the middles are soft and bright orange, they're done.
