Toss the cut sweet potatoes in cornstarch before the oil. Sweet potatoes lack the starch that crisps a russet, and that thin cornstarch coat is what builds a crisp shell instead of a limp, steamy fry.

Can you make Sweet Potato Fries in an air fryer? — Yes
Yes — this is exactly what an air fryer does well. Work in a single layer so the air can move, and shake or flip halfway for even crisping. It runs a touch faster than the oven, so check early.
