Get ready for the crispiest sweet potato fries ever! I’ve uncovered the secret to making them perfectly crunchy every time. Though it takes a little effort and time, that first satisfying crunch makes it all worthwhile. Say goodbye to soggy sweet potatoes forever!

Extra Crispy Sweet Potato Fries

**Potatoes:**

  • 3 large sweet potatoes
  • 2 to 3 tablespoons of cornstarch
  • Vegetable oil for frying

**Batter:**

  • 1/2 cup of cornstarch
  • 3/4 to 1 cup of cold club soda

**Other:**

  • Salt for the fries
  1. Begin by rinsing and peeling the sweet potatoes thoroughly.
  2. Cut each potato into rectangular slices, about 1/4 inch thick. Then, slice across to achieve the classic fry shape, also 1/4 inch thick. I prefer them thin, but you can adjust the thickness to your liking.
  3. Place the slices in a bowl of ice water and let them soak for 30 minutes.
  4. Drain the ice water and rinse the potatoes 2 to 3 times, shaking them well to remove excess starch.
  5. Bring a pot of water to a boil and add the potatoes. Boil for just 3 to 5 minutes; they should not be too soft.
  6. Pat the fries completely dry and place them in a tray or large bowl. Sprinkle with cornstarch and shake to coat evenly.
  7. In a small bowl, mix cornstarch and club soda to make the batter.
  8. Heat oil in a frying pan over medium-low heat until it reaches about 250°F. The oil shouldn’t be too hot for the first fry.
  9. Add the French fries and flash fry for 4 to 6 minutes. They won’t turn golden yet, but they’ll hold their shape.
  10. Fry in batches to avoid overcrowding the pan.
  11. Increase the oil temperature to about 350°F. Fry the fries again until golden and crispy, ensuring they brown evenly.
  12. Transfer to a wire rack to drain excess oil. Sprinkle with salt.
  13. Enjoy your crispy sweet potato fries with ketchup or your favorite dipping sauce!
