Main Ingredients:
- 2 large sweet potatoes (about 1 ½ pounds), peeled or skin-on for extra fiber
- 2 tablespoons cornstarch or arrowroot powder (for crispiness)
- 2 tablespoons olive oil or avocado oil
- ½ teaspoon smoked paprika
- ½ teaspoon garlic powder

- ¼ teaspoon black pepper
Optional Flavor Boosters:
- ½ teaspoon chili powder for heat
- 1 tablespoon grated Parmesan for a savory finish
- Fresh herbs (rosemary or thyme) for aroma
For Serving:

Step-by-Step Directions for Crispy Oven-Baked Sweet Potato Fries 👩🍳
Follow these detailed steps to make oven-baked sweet potato fries that are perfectly crisp, evenly cooked, and bursting with flavor — no fryer required!
- Preheat the Oven: Set your oven to 425°F (220°C) and line two large baking sheets with parchment paper. Proper heat and airflow are key to crispiness.
- Cut the Fries: Slice sweet potatoes into thin, even matchsticks about ¼ inch thick. Uniform pieces ensure even cooking.
- Soak for Crispiness: Place fries in a bowl of cold water for at least 30 minutes. This removes excess starch, helping them crisp up in the oven.
- Dry Thoroughly: Drain and pat the fries completely dry with a clean kitchen towel or paper towels — moisture is the enemy of crispness.
- Coat with Cornstarch: In a large bowl, toss the fries with cornstarch until evenly coated. Shake off any excess powder.
- Add Seasoning & Oil: Drizzle with olive oil and sprinkle smoked paprika, garlic powder, salt, and pepper. Toss until each fry is lightly coated.
- Arrange for Airflow: Spread fries in a single layer on the baking sheets without overlapping. Crowding causes steaming instead of crisping.
- Bake to Perfection: Bake for 15 minutes, flip the fries, then bake another 15–20 minutes until golden and crisp.
- Final Touch: Sprinkle with extra salt or Parmesan while hot, and serve immediately with your favorite dipping sauce.
The result? Crispy, flavorful fries with tender insides — the perfect side dish or snack that’s both healthy and satisfying.
The Science Behind Crispy Sweet Potato Fries
Making crispy baked sweet potato fries can be tricky because sweet potatoes naturally contain more moisture and less starch than regular potatoes. But with the right techniques, you can overcome that challenge for crave-worthy results.
- Soaking the fries removes surface starch, which helps them brown evenly and develop crisp edges.
- Cornstarch coating adds a light, crunchy layer that mimics the effect of deep-frying.
- High-heat baking at 425°F promotes caramelization and creates that beautiful golden crust.
- Proper spacing ensures that hot air circulates around each fry, allowing even browning instead of steaming.
- Flipping halfway through baking guarantees a uniform texture on all sides.
Another secret: using convection bake (if your oven has it) enhances airflow and gives fries an extra crisp finish. Avoid adding too much oil — just enough to lightly coat — since excess oil can cause sogginess. These steps turn your fries from limp to legendary. Once you try this method, you’ll never go back to deep-fried versions again!

Tips, Storage, and Reheating for the Best Sweet Potato Fries
Even the best oven-baked sweet potato fries can lose their crispness if not stored or reheated properly. Here’s how to keep them perfect every time:
- Bake, Don’t Overcrowd: Always use two trays if needed to avoid crowding — air circulation equals crispiness.
- Reheat for Crispness: Place leftover fries on a baking sheet and reheat at 400°F for 8–10 minutes. Avoid microwaving, which softens them.
- Make Ahead: Slice and soak fries in advance, then store them in water in the refrigerator for up to 24 hours. Drain and dry before baking.
- Add Cornstarch Right Before Baking: Don’t coat fries too early — cornstarch absorbs moisture if left too long.
- Storage: Keep cooled fries in an airtight container in the refrigerator for up to 3 days.
- Crisp Again with an Air Fryer: If you have an air fryer, reheat at 375°F for 5 minutes to revive their crunch.
With these pro tips, your fries will stay crisp, flavorful, and ready to impress every single time. It’s a healthy indulgence you’ll crave again and again — without ever reaching for the fryer!
