Ingredients
Scale
- 2 large sweet potatoes, scrubbed and cut into 1/4-inch thick fries
- 1 tablespoon cornstarch
- 1 tablespoon olive oil
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Instructions
- Soak the cut sweet potato fries in a large bowl of cold water for at least 30 minutes. This step removes excess starch and helps them crisp up.
- Preheat your oven to 425°F (220°C). Line two large baking sheets with parchment paper.
- Drain the sweet potato fries completely and pat them very dry using paper towels or a clean kitchen cloth. You must remove as much moisture as possible.
- In a medium bowl, toss the dry fries with the cornstarch until lightly coated.
- Drizzle the fries with olive oil and toss again to coat evenly.
- In a small bowl, mix the paprika, garlic powder, salt, and pepper. Sprinkle this seasoning mix over the fries and toss until the seasoning is distributed.
- Arrange the seasoned fries in a single layer on the prepared baking sheets. Do not overcrowd the pans; use two sheets if necessary for maximum crispiness.
- Bake for 15 minutes, then flip the fries. Return to the oven and bake for another 10 to 15 minutes, or until the edges are golden brown and crispy.
- Serve immediately with your favorite dipping sauce.
Notes
- For extra crispy sweet potato fries, ensure your sweet potatoes are completely dry before adding the oil and cornstarch.
- If you prefer air fryer sweet potato fries, cook at 400°F (200°C) for 15-20 minutes, shaking the basket halfway through.
