For the Fries

  • 2 medium sweet potatoes washed, peeled
  • 4 teaspoon cornstarch
  • 1 teaspoon salt
  • ½ teaspoon pepper
  • 2 tablespoon olive oil
  • 2-3 tablespoon truffle oil

For Dipping Sauce

  • 4 tablespoon mayonnaise
  • 2 tablespoon sour cream
  • 1 tablespoon dill or parsley chopped


  • Cut the peeled potatoes lengthwise into thin strips, about a ¼-½ inch in thickness. Place the fries into a large bowl with cold water for at least 30 minutes (or up to 2 hours). This will help to rinse off the excess starch and make them crispy in the end. When done, don’t forget to pat dry the fries with a paper towel.
  • Next, toss potatoes in cornstarch until evenly coated, then add paprika, salt, pepper. And drizzle with olive oil, toss to combine.
  • Preheat oven to 425 F.
  • Spread the fries onto a baking tray lined with parchment paper. It’s important that you spread them out to give them plenty of space to ensure they crisp up on the edges - use two trays or bake in batches. If needed, use a brush to apply the olive oil onto fries to make sure all of them are covered in it.
  • Bake for 20-25 minutes, then flip the fries over and bake for 10-12 minutes more (or until you see the edges become golden brown and crispy).
  • When fries are ready, place them in a large bowl and drizzle truffle oil, and additional salt and pepper (if needed).
  • When done, serve sweet potato fries on their own or sprinkled with vegan parmesan or regular grated parmesan, chopped parsley and mayo sour cream dipping sauce.
