Set oven to 220°C and insert a baking sheet to heat while preparing sweet potatoes.
02 -
Peel sweet potatoes if desired. Slice into uniform fries approximately 0.6 cm thick to promote even cooking.
03 -
Immerse sliced sweet potatoes in a bowl of cold water for 30 minutes to draw out excess starch, aiding crispiness.
04 -
Drain fries and thoroughly pat dry with paper towel. In a large bowl, toss with olive oil, garlic powder, paprika, salt, and black pepper. If desired, add cornstarch and toss to evenly coat.
05 -
Carefully remove the heated baking sheet from the oven. Arrange sweet potato fries in a single layer, ensuring they are not overcrowded. Bake for 25–30 minutes, flipping fries midway through, until golden and crisp.

Remove fries from the oven once crisp and golden brown. Allow to cool briefly before serving.
