A Quick Hack

To make crispy sweet potato fries, skip salting until after cooking. Salt pulls moisture from foods, which can cause sogginess preventing the fries from getting crispy.

The Recipe

  • 2-3 sweet potatoes, peeled
  • 2 Tablespoons cornstarch {optional but adds a considerable amount of crispness}
  • 2 tablespoons olive oil
  • cayenne pepper, paprika, black pepper and/or garlic powder
  • 1/2 teaspoon sea salt, to taste


  1. Heat the oven to 425 degrees and line 2 large sheet pans with parchment paper.
  2. Cut the sweet potatoes into sticks 1/4 to 1/2 inch wide and toss them with cornstarch {optional}. Drizzle on olive oil and optional seasonings and toss again.
  3. Spread them out on two rimmed baking sheets and bake until brown and crispy on the bottom, about 20 minutes. Flip and crisp for 10-15 minutes on the other side.
  4. Remove and season generously with salt.
  5. You will know when the fries are done cooking when they change from glossy to matte in color.
