  • 1 pound sweet potatoes, peeled
  • 2 tablespoons neutral oil (olive, vegetable, canola, etc. all work)
  • 2 tablespoons cornstarch
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika
  • table salt, to taste


  1. Cut your sweet potatoes into 1/4 inch square fry-shaped pieces. Consistency in the thickness of the potato is key for evenly and properly cooked potatoes.
  2. Place the cut sweet potatoes in a bowl and cover with cold water. Let soak for at least 30 minutes or up to 12 hours (they can soak overnight without issue).
  3. After the sweet potatoes soak, remove from the water and pat dry with a clean dish towel or paper towels.
  4. Add the dry sweet potatoes to a large bowl or zipper-top bag and drizzle with the oil. Toss well to coat evenly.
  5. In a small bowl, combine the cornstarch, garlic powder, and smoked paprika. Sprinkle over the oiled sweet potatoes and toss again to evenly coat.
  6. Preheat the oven to 425 degrees F.
  7. Spread the sweet potatoes in an even layer on a parchment-lined baking sheet.
  8. Bake in the preheated oven for 15 minutes.
  9. Remove from the oven and use a spatula to flip every fry over, one by one.
  10. Return the oven and bake for an additional 10 to 15 minutes.
  11. Remove from the oven and sprinkle with salt.
  12. Let the fries rest for 5 minutes before serving warm.


  • Don't skip any of the steps. You'll want evenly cut taters, to soak, coat, flip, and rest before eating if you want perfect sweet potato fries.
  • Feel free to change up the seasonings to meet your liking! There are so many great options that you can add. Want a little heat? Try adding some chipotle chili powder to your seasoning and corn starch mix.
  • These are perfect with some dipping sauce! I love to use equal parts ketchup, mayo, BBQ, hot sauce, and mustard for a great sweet potato fry dipping sauce.
  • I'm 90% sure that arrow root powder would work in place of the cornstarch just FYI.
