  • 2 pounds sweet potatoes
  • 1 tablespoon cornstarch
  • 1/2 teaspoon salt
  • 1 teaspoon brown sugar optional
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika
  • 1/4 teaspoon chipotle powder
  • 1/4 teaspoon cinnamon
  • 1/2 teaspoon cracked black pepper
  • 2 tablespoons coconut oil melted, or olive oil


  • Place rack in the upper 1/3 of the oven. If using 2 racks place one in the upper 1/3 and one in the lower 1/3.
  • Mix the cornstarch and salt. Set aside.
  • Mix the brown sugar and remaining spices. Set aside.
  • Preheat the oven to 425F.
  • Oil baking sheets lightly with oil.
  • Peel the sweet potatoes and cut them into fries about 1/4-inch wide by 1/4-inch thick. Make them as evenly sized as possible.
  • Toss into the cornstarch and salt mixture to coat evenly - shaking off excess.

Oven Instructions

  • Place half on each baking sheet, in a single layer, being careful not to overcrowd.
  • Drizzle oil over the fries and toss to coat with oil.
  • Bake for 20 minutes.
  • Remove the pans from the oven and carefully flip the fries so the other side can get crisp.
  • Bake for 15 more minutes, or until they are crispy.
  • Watch carefully - they'll burn pretty quickly.
  • Remove from oven and season with the seasoning mixture.
  • Let stand for 5 minutes.
  • Serve hot.

Air Fryer Instructions

  • Arrange about half of the uncooked sweet potato fries in a single layer in an air fryer basket - make sure there is plenty of room between them.
  • Air fry at 375F for 8 minutes.
  • Flip and air fry for 8 more minutes.
  • Remove from air fryer and sprinkle with seasoning.
  • Repeat with remaining sweet potato fries.


  • It's been said but it bears repeating - be sure to cut the fries in thin, even pieces- about 1/4-inch thick.
  • Sweet potato fries can be cut a day or two ahead of time and stored in the refrigerator until you're ready to bake. If you keep them in a bowl of water with a little squeeze of lemon in it they won't discolor. Just be sure to pat them very dry before finishing the recipe.
  • Always flip the fries about halfway through.
  • Don't crowd them or they will steam rather than oven-fry.
  • Let sweet potato fries rest for around 5 minutes after they come out of the oven to crisp up even more.
  • Don't let them sit too long or they will get soggy.
  • They are best when they come right out of the oven but you can warm up leftovers in the oven until they crisp back up.
