Ingredients

  • 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

Instructions

  • 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.
  • 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 issues).
  • After the sweet potatoes soak, remove from the water and pat dry with a clean dish towel or paper towels.
  • Add the dry sweet potatoes to a large bowl or zipper-top bag and drizzle with the oil. Toss well to coat evenly.
  • In a small bowl, combine the cornstarch, garlic powder, and smoked paprika. Sprinkle over the oiled sweet potatoes and toss again to evenly coat.
  • Preheat the oven to 425 degrees F.
  • Spread the sweet potatoes in an even layer on a parchment-lined baking sheet.
  • Bake in the preheated oven for 15 minutes.
  • Remove from the oven and use a spatula to flip every fry over, one by one.
  • Return the oven and bake for an additional 10 to 15 minutes.
  • Remove from the oven and sprinkle with salt.
  • Let the fries rest for 5 minutes before serving warm.

Notes

  • Don't skip any of the steps. You'll want evenly cut taters, to soak, coat, flip, and rest before eating if you want crisp sweet potato fries.
  • Don't add salt until after baking the sweet potato fries (the salt draws out moisture and that won't help them crisp).
  • You can use arrowroot powder in place of cornstarch but it's generally recommended that you need twice the amount. 
  • Sweet potato fries are perfect with some dipping sauce! Equal parts of ketchup, mayo, BBQ, hot sauce, and mustard makes a great dipping sauce.
  • These fries don't store well in the freezer or fridge so make what you need.
