Golden, crispy-on-the-outside, tender-on-the-inside sweet potato fries made in the oven—no frying required. A healthy, vegan-friendly side or snack that defies soggy expectations.

  • Total Time: 35 minutes
  • Yield: 4 servings 1x

Ingredients

Scale
  • 2 large sweet potatoes (about 1.5 lbs)
  • 1 tablespoon cornstarch
  • 1 tablespoon olive oil
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • Optional: paprika, garlic powder, or cinnamon for seasoning

Instructions

  1. Preheat oven to 450°F (230°C) and line two baking sheets with parchment paper.
  2. Peel sweet potatoes and cut into 1/4-inch thick uniform fries.
  3. Toss fries in a bowl with cornstarch until evenly coated.
  4. Add olive oil, salt, and any desired seasonings; toss again to coat.
  5. Arrange in a single layer on baking sheets, ensuring space between each fry.
  6. Bake for 12 minutes, flip, then bake 8–10 more minutes until golden and crisp.
  7. Let cool 2–3 minutes before serving—this final step ensures maximum crispness!

Notes

  • Dry the sweet potatoes thoroughly before coating with cornstarch for best results.
  • For extra crispiness, soak cut fries in cold water for 15 minutes, then pat extremely dry.
  • Cornstarch is key—it draws out moisture and creates a crisp crust.
