Hi, I’m Sam from dishfoody.com, where comforting classics get a fresh twist. Crispy Oven Baked Sweet Potato Fries transform humble tubers into shatter-crisp matchsticks using cornstarch coating and double-pan spacing for restaurant-quality crunch without deep frying. Ready in 35 minutes, they serve 4 with smoky seasoning clinging to golden exteriors perfectly.
Why This Recipe Works
Cornstarch draws moisture for shattering crisp. Soaking removes excess starch preventing gumminess. High heat + oil spray maximizes browning. Parchment prevents sticking while allowing airflow. Strategic flipping ensures even crisp development.

- 2 tbsp cornstarch
- 3 tbsp olive oil
