Ingredients
  

  • 2 large sweet potatoes, peeled and cut into ½-inch thick fries
  • 2 tablespoons olive oil
  • 1 tablespoon cornstarch
  • 1 teaspoon garlic powder
  • 1 teaspoon paprika
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • Water for soaking

Equipment

  • parchment paper
  • paper towels
  • knife
  • cutting board
  • Measuring spoons
  • Measuring cups

Method
 

  1. Preheat your oven to 400°F (200°C).
  2. Cut the sweet potatoes into uniform ½-inch thick fries.
  3. Place the cut fries in a bowl of cold water for at least 30 minutes, or up to 2 hours.
  4. Drain the fries well and pat completely dry with paper towels.
  5. In a large bowl, toss the dried sweet potato fries with cornstarch until evenly coated.
  6. Add the olive oil, garlic powder, paprika, salt, and pepper to the bowl.
  7. Toss until the fries are evenly coated with the oil and spices.
  8. Spread the fries in a single layer on a large baking sheet lined with parchment paper. Ensure the fries are not overcrowded.
  9. Bake for 20-25 minutes, flipping the fries halfway through, until they are golden brown and crispy.
  10. Serve immediately while they are still hot and crispy.

Notes

Soaking the sweet potato fries in cold water is crucial for removing excess starch and achieving crispiness. Patting the fries completely dry after soaking is equally important. For extra crispiness, ensure the fries are spread in a single layer on the baking sheet. Avocado oil can be used as a substitute for olive oil. Store leftover fries in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or air fryer to restore crispness.
