Crispy oven baked sweet potato fries are one of my favorite sides — naturally sweet, perfectly seasoned, and satisfyingly crisp without needing a deep fryer. They’re a healthier take on classic fries, and I love dipping them in everything from ketchup to spicy aioli.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Sweet potatoes, peeled and cut into thin fries
Cornstarch or arrowroot powder (for crispiness)
Olive oil
Paprika or smoked paprika
Garlic powder
Salt
Black pepper
Optional: chili powder, cayenne, or herbs for extra flavor

Directions

I preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper.
I cut the sweet potatoes into evenly sized thin fries — thinner is better for crispiness.
I toss the fries with cornstarch first, making sure each piece is lightly coated. This is my key step for crispy texture.
I then add olive oil and seasonings, tossing to coat everything evenly.
I spread the fries out in a single layer on the baking sheet, making sure they’re not crowded.
I bake for 15 minutes, flip them, and bake for another 10–15 minutes until golden and crisp on the edges.
I let them rest a few minutes before serving — that helps them crisp up even more.

Servings and timing

This recipe makes 2 to 3 servings. It takes 10 minutes to prep and about 25–30 minutes to bake.

Variations

I change the seasoning all the time — sometimes I go for cinnamon and cayenne for a sweet-spicy combo, or toss them with rosemary and parmesan after baking for a more savory approach. I also make chipotle mayo or honey mustard for dipping.

Storage/reheating

These fries are best fresh, but I store leftovers in the fridge for up to 2 days. To reheat, I pop them back in a hot oven or air fryer to crisp them up. Microwaving makes them soft, so I avoid it when I want that crispy bite. Crispy Oven Baked Sweet Potato Fries

FAQs

How do I keep sweet potato fries from getting soggy?

I make sure to coat them with cornstarch, don’t overcrowd the pan, and flip them halfway through baking. These steps help a lot.

Can I make them in the air fryer?

Yes, I often do! I cook them at 400°F for 12–15 minutes, shaking the basket halfway through.

Do I need to soak the sweet potatoes before baking?

It’s not necessary for sweet potatoes, but I’ve done it for extra crispness. If I do soak them, I dry them completely before coating.

Can I leave the skin on?

Definitely. I scrub them well and leave the skin on when I want more texture and fiber.

Are these fries gluten-free?

Yes — just make sure to use gluten-free cornstarch or arrowroot powder.

Conclusion

Crispy oven baked sweet potato fries are a side dish I never get tired of. They’re easy, flavorful, and just as satisfying as fried versions — plus, they pair well with just about anything. Whether I’m serving burgers, wraps, or just snacking, these fries always hit the spot.
