Step-by-Step Guide: How to Make Crispy Oven-Baked Sweet Potato Fries
1. Choose the Right Sweet Potatoes
For the crispiest fries, choose fresh, firm sweet potatoes with minimal blemishes. Avoid those with wrinkles or soft spots, as they may contain excess moisture, leading to soggy fries.
2. Preheat the Oven & Prepare the Baking Sheet
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or a silicone baking mat. Avoid aluminum foil, as fries may stick or burn easily.
3. Peel & Cut the Sweet Potatoes
- Peel the sweet potatoes using a sharp vegetable peeler.
- Cut them into ¼-inch thick matchsticks. Keeping them uniform in size ensures even cooking.
- Pro Tip: If you prefer skin-on fries, give the potatoes a good scrub instead of peeling them.
4. Soak the Sweet Potatoes (Crucial for Crispiness!)
- Place the cut fries in a large bowl of cold water and let them soak for at least 30 minutes (or up to an hour).
- This step removes excess starch, preventing fries from turning soggy.
- After soaking, drain the fries and pat them completely dry with a clean kitchen towel or paper towels.
5. Coat with Cornstarch & Oil
- In a large mixing bowl, toss the dry sweet potatoes with 2 tablespoons of cornstarch.
- Once coated, drizzle with olive oil and toss again to evenly distribute the oil.
- Why Cornstarch? It helps absorb moisture and creates a crisp outer layer when baked.
6. Season the Fries
Sprinkle the seasonings (salt, pepper, paprika, garlic powder, onion powder, and cayenne) evenly over the fries and mix well to coat each piece with flavor.
7. Arrange on the Baking Sheet
- Spread the fries in a single layer on the prepared baking sheet, ensuring they don’t overlap.
- Spacing is key! Crowding causes steam buildup, making fries soggy instead of crispy.
8. Bake to Perfection
- Place the fries in the preheated oven and bake for 20 minutes.
- After 20 minutes, flip the fries using tongs to ensure even crispiness.
- Continue baking for another 10-15 minutes or until the edges turn golden brown and crispy.
- Watch closely! Sweet potatoes contain natural sugars, which can burn quickly.
9. Serve & Enjoy!
- Remove fries from the oven and sprinkle with fresh parsley or parmesan cheese if desired.
- Serve immediately with your favorite dipping sauces.
Tips for Extra Crispy Sweet Potato Fries
- Soak & Dry Thoroughly – Removing excess starch and moisture is the key to crispiness.
- Use Cornstarch – This helps create a crisp coating without deep frying.
- Don’t Overcrowd the Pan – Always spread fries in a single layer. Use multiple pans if needed.
- Bake at High Heat – 425°F is ideal for achieving a crispy texture without burning.
- Flip the Fries – Turning them halfway ensures even browning.
Flavor Variations & Seasoning Ideas

- Spicy Cajun Fries – Add a teaspoon of Cajun seasoning for a bold kick.
