Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup.

Step 2: Prepare the Sweet Potatoes
Peel the sweet potatoes and cut them into thin, uniform strips to ensure even cooking.

Step 3: Coat with Cornstarch
Place the sweet potato strips in a bowl and toss with cornstarch. This helps absorb moisture and makes them crispier.

Step 4: Season and Add Oil
Drizzle the fries with olive oil, then sprinkle with garlic powder, paprika, cayenne (if using), salt, and black pepper. Toss until evenly coated.

Step 5: Arrange and Bake
Spread the fries in a single layer on the baking sheet, ensuring they don’t overlap. Bake for 15 minutes, then flip and bake for another 10-15 minutes until crispy.

Step 6: Serve and Enjoy
Remove from the oven and let them cool slightly. Serve with your favorite dipping sauce.
