Oven Baked Sweet Potato Fries Crispy Perfection
Forget soggy, greasy fries. This recipe unlocks the secret to perfectly crispy oven-baked sweet potato fries with a caramelized edge and a soft, sweet interior. A crucial cold water soak and a cornstarch coating deliver restaurant-quality crunch without a deep fryer.
Equipment
- Large bowl
- Clean Kitchen Towel
- Chef's knife
- Cutting board
- Whisk
- Two large rimmed baking sheets
- Parchment paper
- Spatula
Ingredients
- 2 large sweet potatoes about 2 lbs
- 3 tablespoons cornstarch
- 3 tablespoons olive oil or avocado oil
- 1 teaspoon smoked paprika
- ½ teaspoon garlic powder
- ½ teaspoon fine sea salt
- ¼ teaspoon black pepper
Instructions
- Wash and scrub the sweet potatoes thoroughly. You may peel them if desired, but leaving the skin on adds fiber and texture. Cut the potatoes into even 1/4-inch to 1/2-inch sticks. Uniformity is critical for even cooking.
- Place the cut fries in a large bowl and cover them with cold water. Let them soak for at least 30 minutes, or up to 2 hours. This washes away excess starch that causes sogginess.
- Drain the soaked fries and pat them bone-dry with a clean kitchen towel. Any remaining moisture will prevent crispiness.
- Preheat your oven to 425°F (220°C).
- In a large bowl, whisk together the cornstarch, smoked paprika, garlic powder, salt, and pepper.
- Add the completely dry sweet potato sticks and the oil to the bowl with the spice mixture. Toss everything together with your hands until every fry is evenly coated.
- Line two large, rimmed baking sheets with parchment paper. Arrange the fries in a single, even layer, making sure they are not touching. Overcrowding will steam them instead of roasting them.
- Bake for 15 minutes, then flip each fry carefully. Continue baking for another 10-15 minutes, until they are deeply golden and crisp on the edges.
- Let the fries cool on the baking sheet for 5 minutes—they will continue to crisp up as they cool. Serve immediately.
Notes
For best results, do not skip the cold water soak—it is the #1 secret to crispy fries. Ensure the fries are completely dry before coating to prevent the cornstarch from turning into a paste. For extra flavor, toss the hot fries with grated Parmesan and fresh herbs, or a squeeze of lime juice and chipotle powder. Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat in a 400°F oven for 5-7 minutes to restore crispiness.
