Smokey Sweet Potato Oven Fries

Its Superbowl Sunday, which means snack day! These Smokey Sweet Potato Oven Fries are crispy, smokey, spicy, and sweet: a perfect game day (or any day) snack. We eat them year round, but always appreciate the excuse for a heaping plate.  

Yield: Serves 2, we recommend using about 1 sweet potato per person


   Sweet potato fries:

  • 2 large sweet potatoes, unpeeled, cut into medium matchsticks (about 1/4 inch thick)
  • 1 tablespoon canola oil
  • 1 teaspoon cornstarch

   Smoky seasoning salt:

  • 1 teaspoon maple sugar (substitute sugar)
  • 1 teaspoon kosher salt
  • 1/2 teaspoon chipotle chili powder
  • 1/4 teaspoon garlic powder
  • 1/8 teaspoon ground cinnamon
  • 1/8 teaspoon ground cumin
  • Pinch (1/16 teaspoon) ground cayenne pepper 


  1. Preheat oven to 425 and prepare a large baking sheet with aluminum foil or silicon baking mat. 
  2. For the smokey seasoning salt: In a small bowl mix together the maple sugar, salt, chipotle, garlic, cinnamon, cumin, and cayenne.
  3. For the sweet potato fries: In a large bowl, toss the sweet potatoes with canola oil. Add cornstarch and toss again to combine, ensuring there are no white granules of cornstarch visible. Add all of the prepared smokey seasoning salt, and toss to combine.
  4. Spread the sweet potato fries on the baking sheet, making sure they do not overlap to ensure even browning. 
  5. Bake for 40-50 minutes, rotating the baking sheet and flipping the fries once during baking. The fries are ready when they are crispy, browned, and no longer have a raw wet looking appearance.
  6. Allow to cool on the sheet for 5 minutes before serving. This allows the fries to crisp up. Note that the fries will always be somewhat softer than a typical deep fried french fry.
