Bake for 20-25 minutes, flipping halfway through, until the fries are golden and crispy.
In a large bowl, toss the sweet potato sticks with olive oil, cornstarch, garlic powder, and paprika until evenly coated.
Preheat the oven to 425°F (220°C). Line two baking sheets with parchment paper.
Season with salt and pepper to taste before serving.
Spread the fries in a single layer on the prepared baking sheets. Avoid overcrowding to ensure even cooking.
Wash and peel the sweet potatoes. Cut them into thin, even sticks for crispy fries.
