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 or avocado oil
Garlic powder
Paprika or smoked paprika
Salt and black pepper
Optional: cayenne pepper or chili powder for a spicy kick

Directions

I preheat the oven to 425°F (220°C) and line two baking sheets with parchment paper.
I peel the sweet potatoes and cut them into thin, even matchstick-sized fries.
I toss the fries with cornstarch first—this helps them get extra crispy.
I drizzle with olive oil and toss again with garlic powder, paprika, salt, and pepper until evenly coated.
I spread the fries in a single layer on the baking sheets, making sure they aren’t crowded.
I bake for 15–20 minutes, flip the fries, then bake for another 10–15 minutes, watching closely during the last few minutes to avoid burning.
I let them cool for a few minutes on the tray to crisp up even more before serving.

Servings and timing

This recipe makes about 3–4 servings and takes around 35–40 minutes from start to finish. It’s great as a side, snack, or party appetizer.

Variations

I sprinkle with parmesan cheese and chopped herbs after baking for a savory twist.
I make them sweet by tossing in cinnamon and a pinch of brown sugar instead of spices.
I serve with dips like chipotle mayo, garlic aioli, or classic ketchup.
I cut them into wedges instead of thin fries for a chunkier version.

storage/reheating

I store leftovers in an airtight container in the fridge for up to 3 days. To re-crisp, I reheat them in the oven or air fryer at 400°F for a few minutes. Microwaving makes them soft, so I avoid that when I want to keep them crisp. Crispy Oven Baked Sweet Potato Fries

FAQs

Why aren’t my fries crispy?

Crowding the pan or skipping the cornstarch can make them soft. I always spread them out in a single layer and flip halfway through baking.

Can I leave the skin on?

Yes! I scrub the sweet potatoes well and leave the skin on for extra texture and nutrients.

What’s the best oil to use?

I prefer olive oil or avocado oil—they both handle high heat well and add great flavor.

Are these healthier than regular fries?

Yes, they’re baked instead of fried and made with sweet potatoes, which are rich in fiber, vitamins, and antioxidants.

Can I freeze them?

Unbaked fries can be frozen in a single layer, then transferred to a bag. I bake them straight from frozen, adding a few extra minutes of cooking time.

Conclusion

Crispy Oven Baked Sweet Potato Fries are a delicious, healthy side dish that I can enjoy any time. I love how customizable they are and how satisfying they feel with that perfect crunchy texture. Whether I’m pairing them with a meal or snacking straight off the tray, these fries always deliver.
