Follow these steps to make sweet potato fries that are crispy on the outside and tender inside, using simple seasonings and baking instead of deep frying.

Ingredients

Scale
  • 3 large sweet potatoes, scrubbed
  • 2 tablespoons olive oil
  • 1 tablespoon cornstarch
  • 1 teaspoon paprika
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

  1. Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). Line two large baking sheets with parchment paper.
  2. Cut the sweet potatoes into uniform fry shapes, about 1/4 to 1/3 inch thick. Do not peel them.
  3. Soak the cut sweet potato fries in a large bowl of cold water for at least 30 minutes. This removes excess starch and helps them crisp.
  4. Drain the fries completely and pat them very dry using paper towels or a clean kitchen towel. This step is crucial for crispiness.
  5. In a large bowl, toss the dry sweet potato fries with olive oil until lightly coated.
  6. Sprinkle the cornstarch, paprika, garlic powder, salt, and pepper over the fries. Toss again until the seasoning and cornstarch evenly coat every fry.
  7. Arrange the seasoned fries on the prepared baking sheets in a single layer. Do not let the fries touch each other; use two sheets if necessary to avoid crowding.
  8. Bake for 15 minutes. Flip the fries carefully.
  9. Return the sheets to the oven and bake for another 10 to 15 minutes, or until the edges are golden brown and crispy.
  10. Serve immediately with your favorite dipping sauce.

Notes

  • For the crispiest results, use two baking sheets and ensure the fries are in a single layer without touching.
  • If you prefer an air fryer method, toss the seasoned fries with 1 teaspoon of oil and cook at 380 degrees Fahrenheit for 12-15 minutes, shaking the basket halfway through.
  • Pair these with a chipotle mayo or honey mustard dip for added flavor.
