Introduction
Oven Roasted Sweet Potato Fries are a delicious and healthier alternative to traditional fries. Crispy on the outside and tender inside, they make a perfect snack or side dish that everyone will love.

Ingredients
- 1 1/2 pounds sweet potatoes (peeled)
- 2 tablespoons olive oil
- 2 tablespoons cornstarch
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon dried parsley
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon ground black pepper
- Fine sea salt (to taste)
Instructions
- Step 1: Slice the sweet potatoes into long, thin strips, about 1/4-inch wide.
- Step 2: Add the fries to a large bowl and cover with cold water. Soak for at least 60 minutes or overnight for best results.
- Step 3: Preheat the oven to 425 degrees F (220 degrees C).
- Step 4: Line a large baking sheet with parchment paper or use two medium baking sheets to ensure the fries have enough room.
- Step 5: Drain the sweet potato fries well, then arrange them in a single layer on a clean towel and pat dry with paper towels. Clean and dry the bowl thoroughly.
- Step 6: Return the fries to the clean bowl, drizzle with olive oil, and toss until evenly coated.
- Step 7: In a small bowl, whisk together cornstarch, garlic powder, onion powder, dried parsley, smoked paprika, and black pepper. Sprinkle this mixture over the fries and toss until evenly coated and the cornstarch has absorbed into the oil.
- Step 8: Spread the fries in a single layer on the prepared baking sheet, making sure they do not overlap.
- Step 9: Bake for 15 minutes, then remove the pan and flip each fry with a spatula to ensure even crisping. Return to the oven and bake for another 10-15 minutes until crispy and lightly browned.
- Step 10: Transfer the fries to a cooling rack, sprinkle with sea salt to taste, and let them rest for 5 minutes.
- Step 11: Serve warm and enjoy!
