How do I make oven baked sweet potato fries even crispier?

Use cornstarch. Toss the dried fries in 1 tablespoon cornstarch before baking. It creates a starchy coating that crisps as it bakes.

Can I skip the soaking step?

Technically yes, but you’ll sacrifice crispiness. Soaking removes starch that causes sogginess. If you're short on time, even 15 minutes helps.

Can I use this method in an air fryer?

Absolutely. Reduce temperature to 375°F (190°C) and cook in small batches for 12–15 minutes , shaking halfway through.

How long do leftover fries stay fresh?

Stored properly, up to 3 days in the fridge. Reheat in the oven—not the microwave—for best texture.

Can I double this recipe for a party?

Yes—just use two trays and rotate them halfway through baking. Keep fries in a single layer for even browning.

Ingredients

2 medium sweet potatoes (about 1 pound), peeled (optional) and cut into 1/4 inch fries
2 tablespoons olive oil
1 teaspoon garlic powder
1 teaspoon paprika (smoked optional)
1 teaspoon salt
1/2 teaspoon black pepper
1 tablespoon cornstarch (optional, for extra crispiness)

Instructions

Preheat oven to 425°F (220°C) and place a baking sheet inside to heat up.
Peel the sweet potatoes if desired and cut them into uniform 1/4 inch thick fries.
Soak the cut fries in cold water for at least 30 minutes to remove excess starch.
Drain and pat the fries completely dry with a paper towel or clean cloth.
In a large bowl, toss the fries with olive oil, garlic powder, paprika, salt, pepper, and cornstarch if using.
Carefully remove the hot baking sheet and spread the fries in a single, spaced-out layer.
Bake for 25–30 minutes, flipping halfway through, until fries are golden brown and crispy.
Let the fries cool for a few minutes before serving.

Notes

For extra crispiness, use cornstarch or arrowroot powder.
Smoked paprika adds depth but can be replaced with chili powder for heat.
Don’t skip drying the fries thoroughly—this prevents sogginess.
Serve with chipotle mayo, garlic aioli, or honey mustard for dipping.
