01 - Preheat the air fryer to 400°F (200°C) for 3 minutes.
02 - Place the cut sweet potato fries into a large mixing bowl and toss with cornstarch until evenly coated.
03 - Drizzle olive oil over the coated fries and toss thoroughly to ensure an even coat.
04 - Add smoked paprika, garlic powder, salt, and black pepper to the fries, mixing well to evenly distribute the seasoning.
05 - Place fries in a single layer inside the air fryer basket, cooking in batches if necessary to avoid overcrowding.
06 - Air fry the fries for 15 to 18 minutes, shaking the basket halfway through the cooking time to promote even crisping, until golden and crispy.
07 - Remove fries from the air fryer, season with additional salt if desired, and serve immediately.
