These air fryer sweet potato fries come out perfectly crispy on the outside and tender on the inside. A simple side dish that's always a crowd-pleaser.
Cut the sweet potatoes into even 1/4-inch thick sticks. Soak them in cold water for 30 minutes, then drain and pat completely dry with paper towels. This step is key for crispy fries.
Place the dried sweet potato sticks in a large bowl. Sprinkle with cornstarch and toss until evenly coated. Add olive oil, garlic powder, smoked paprika, cinnamon, salt, and pepper, and toss again.
Preheat the air fryer to 380°F (193°C) for 3 minutes.
Spread the fries in a single layer in the air fryer basket, working in batches if needed to avoid overcrowding. Cook at 380°F for 12 to 15 minutes, shaking the basket every 5 minutes.
Increase the temperature to 400°F and cook for 2 to 3 more minutes until the edges are crispy and lightly charred. Serve immediately.
