How to Make the Crispiest Oven-Baked Sweet Potato Fries
Achieving crispy fries without the fryer is simple with a few key tips. Here’s how to get that satisfying crunch:
- Cut the Fries Evenly: The key to perfectly crispy fries is uniformity. Cut your fries into evenly sized pieces to ensure they cook at the same rate.
- Soak the Sweet Potatoes: Soaking the fries in cold water for at least 30 minutes before baking helps remove excess starch, which is essential for crispy fries.
- Use a Hot Baking Sheet: Preheating your baking sheet in the oven helps the fries start cooking immediately, ensuring a crisp exterior.
- Don’t Overcrowd the Pan: Spread your fries out in a single layer with enough space between them. Crowding the fries will lead to steaming rather than crisping.
Ingredients You’ll Need
- 2 medium sweet potatoes (peeled if desired)
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon paprika (smoked paprika adds extra flavor)
- Salt and pepper to taste
- Optional: 1 tablespoon cornstarch for extra crispiness
Step-by-Step Guide to Crispy Sweet Potato Fries
Follow these easy steps to create crispy sweet potato fries right from your oven:
- Preheat the Oven: Set your oven to 425°F (220°C) and place a baking sheet inside to heat up.
- Prepare the Sweet Potatoes: Peel (if preferred) and cut the sweet potatoes into 1/4-inch thick fries. Keep the pieces as uniform as possible for even cooking.
- Soak the Fries: Place the cut fries into cold water for 30 minutes. This step removes excess starch, which helps the fries crisp up better in the oven.
- Season the Fries: Drain and pat the fries dry with paper towels. Toss them in a bowl with olive oil, garlic powder, paprika, salt, and pepper. If you want extra crispiness, add 1 tablespoon of cornstarch and toss everything together.
- Bake the Fries: Carefully remove the hot baking sheet from the oven and spread the fries in a single layer. Bake for 25-30 minutes, flipping halfway through to ensure even crisping.
- Check for Crispiness: Once the fries are golden brown and crispy, remove them from the oven and let them cool for a few minutes before serving.
Dipping Sauces to Pair with Sweet Potato Fries
Sweet potato fries are delicious on their own, but they’re even better when paired with a tasty dip. Try these homemade sauces:
- Garlic Aioli: Combine mayo, garlic, lemon juice, and a pinch of salt for a creamy, garlicky dip.
- Chipotle Mayo: Mix mayo with chipotle sauce, lime juice, and honey for a spicy-sweet twist.
- Honey Mustard: Combine equal parts honey and mustard for a tangy-sweet dip that’s perfect with fries.
Common Mistakes to Avoid
While baking sweet potato fries is simple, a few missteps can affect the crispiness. Avoid these common mistakes:
- Overcrowding the Pan: Make sure there’s enough space between the fries. Overcrowding traps steam and results in soggy fries.
- Not Drying the Fries: After soaking, dry the fries thoroughly to avoid excess moisture, which prevents them from crisping up.
- Skipping the Flip: Flip your fries halfway through baking to ensure even cooking and crispiness.
- Skipping the Cornstarch: For extra crispy fries, use cornstarch—it creates a light coating that helps absorb moisture and gives a golden, crispy exterior.
Storing and Reheating Leftovers
If you’re lucky enough to have leftovers, here’s how to store and reheat them without losing their crispiness:
- Storing: Let the fries cool completely before placing them in an airtight container. They’ll stay fresh in the refrigerator for up to 3 days.
- Reheating: To restore their crispiness, reheat the fries in a preheated oven at 375°F (190°C) for 10 minutes. Avoid the microwave, which will make them soggy.
Recipe FAQ’s
- How do I make my fries even crispier?
Add cornstarch to your fries before baking. It creates a crispy coating that helps absorb moisture and results in a crunchier texture. - Can I skip soaking the sweet potatoes?
While soaking is optional, it helps remove excess starch, making your fries crispier. If you’re in a hurry, you can skip this step but they might not be as crisp. - Can I use regular potatoes instead of sweet potatoes?
Yes! Regular potatoes work just as well with this method. The same technique applies to both sweet and white potatoes.
