No reviews

These oven-baked sweet potato fries are crispy on the outside, tender on the inside — with no frying required. Tossed in olive oil, cornstarch, and seasonings for maximum crunch, they’re a healthy, vegan-friendly snack or side.

  • Total Time: 40 minutes
  • Yield: 4 servings

Ingredients

Scale
  • 2 large sweet potatoes, peeled and cut into 1/4-inch thick fries
  • 1 tablespoon cornstarch
  • 2 tablespoons olive oil
  • 1 teaspoon sea salt
  • 1/2 teaspoon smoked paprika
  • 1/4 teaspoon black pepper

Instructions

  1. Preheat oven to 450°F (230°C) and line a baking sheet with parchment paper.
  2. Pat sweet potato fries completely dry with a clean towel.
  3. Toss fries with cornstarch until lightly coated, then add olive oil, salt, paprika, and pepper — shake gently to coat evenly.
  4. Arrange in a single layer with space between each fry — overcrowding causes sogginess.
  5. Bake for 15 minutes, flip, then bake 10–12 more minutes until golden and crisp.
  6. Let cool 2–3 minutes before serving for optimal crispness.

Notes

  • For extra-crispy fries, soak cut sweet potatoes in cold water for 15 minutes, then dry *thoroughly* before coating.
  • Use cornstarch — it’s the secret to that restaurant-style crunch without deep-frying.
  • Don’t skip the flip halfway through — ensures even browning on both sides.
