I’ve tried so many different methods for getting crispy sweet potato fries—from soaking the potatoes to leaving them in the oven after cooking to keeping the skin on. This method of baking sweet potato fries is by far the easiest, best way to get consistently crispy potatoes. My secret weapon? Cornstarch! After drying the sweet potatoes well, coating them with the cornstarch and olive oil, and cooking these sweet potato fries in the oven, they come out perfect every time.

Ingredients to Make Sweet Potato Fries

Ingredients for recipe: oil, salt, pepper, cornstarch, and sweet potatoes.
  • Sweet potatoes: Look for firm potatoes with smooth skin. You can peel them or leave the skin on—it won’t impact the cooking time or texture!
  • Cornstarch: If you’re out of cornstarch, arrowroot powder or tapioca flour can work in a pinch.
  • Olive oil: This helps the fries crisp up in the oven and adds flavor. You can also use avocado oil or melted coconut oil.
  • Salt and pepper: For flavor, of course!
  • Add spices. Toss in your favorite herbs and spices, like garlic powder, smoked paprika, or a hint of cayenne, for some heat.
  • Make it sweet. For a sweet and salty flavor, sprinkle in some cinnamon along with the salt and pepper before baking.
  • Serve the baked sweet potato fries with a dip. While ketchup is classic, consider serving these fries with aioli, ranch dressing, or honey mustard.
  • Make it cheesy. After cooking, sprinkle on grated parmesan, pecorino romano, or cheddar onto the fries, then pop them back into the oven until the cheese melts.

Tips for Making the Best Sweet Potato Fries Recipe

  1. Cut the ends off of the sweet potatoes. The ends are pointy and will be the first parts of the potato to burn, so I recommend cutting them off!
  2. Cut the sweet potatoes into similar-sized, thin strips. This will help them to cook evenly and quickly.
  3. Make sure the fries are really coated in the cornstarch. This is so they dry out and get crispy. You’ll want to gently shake the fries and remove any excess cornstarch before adding them to the baking sheet, though!
  4. Use parchment paper to line the baking sheet. Not only does it make for easier clean-up, but it also keeps the baked sweet potato fries from sticking to the pan.
  5. Place the fries in a single layer on the baking sheet, without them touching. This will help them to get crispy all over, not steam, and come out soggy!

What to Serve With Crispy Sweet Potato Fries

Frequently Asked Questions

How do I store and reheat baked sweet potato fries?

Once your homemade sweet potato fries have cooled to room temperature, place them in an airtight container or a resealable plastic bag and store them in the fridge for up to 3-4 days. Make sure they’re spread out a bit so they don’t stick together. To reheat, just place them in the oven at 375°F for 5 minutes or in a toaster oven. You can also use the air fryer.

Can I freeze them?

You can freeze them! Simply lay the fries on a baking sheet, ensuring they’re not touching, and freeze until solid. Once they’re frozen, transfer them to a freezer bag and store. When you’re ready to enjoy them again, reheat them straight from the freezer.

Why aren’t my sweet potato fries crispy?

If your fries aren’t as crispy as you’d like, you may have overcrowded the baking sheet. Make sure the fries have plenty of space between them to bake evenly. Another factor could be the cornstarch; make sure the fries are well-coated, but shake off any excess.

Can I skip the cornstarch?

Cornstarch helps absorb moisture and makes the fries crispier. You can skip it, but the potatoes might not get as crispy.

Instructions

  • Preheat the oven to 425°F and line two large, rimmed baking sheets with parchment paper.
  • Cut both ends of the sweet potatoes to square them off. Then slice the sweet potatoes and cut each slice into thin even strips, about ¼” in thickness all around. Transfer to a large bowl.
  • Sprinkle the cornstarch over the sweet potatoes and use your hands to toss together, making sure all the fries are well coated.
  • Divide the sweet potato strips between the two baking sheets, and leave behind any excess cornstarch in the bowl. Drizzle the olive oil on top and season with salt and pepper. Use your hands again to toss the potatoes until there are no more visible streaks of cornstarch.
  • Arrange the potatoes in a single layer, making sure not to overcrowd them. Bake for 20 minutes, then use a spatula to flip the fries and cook until they’re lightly browned and puffed, about 10-15 more minutes.
  • Remove from heat, add additional salt, if desired, and serve immediately.
