Preheat your oven to 425°F (220°C) and place a baking sheet inside to heat.
02 -
Peel the sweet potatoes (optional) and cut them into 1/4 inch thick fries, ensuring they are uniform for even cooking.
03 -
Place the cut sweet potato fries in a bowl of cold water for 30 minutes to remove excess starch for crispiness.
04 -
Drain the fries and pat them dry with a paper towel. Toss them in a large bowl with olive oil, garlic powder, paprika, salt, and black pepper. Add cornstarch if using and mix well.
05 -
Carefully remove the hot baking sheet from the oven. Spread the fries evenly in a single layer, avoiding overcrowding. Bake for 25-30 minutes, flipping halfway through, until golden brown and crispy.
06 -
Remove the fries from the oven once crispy and golden. Allow them to cool for a few minutes before serving.
