Ingredients

  • 2 pounds sweet potatoes
  • 2 tablespoons avocado oil
  • 1 ½ teaspoon sea salt
  • 1 tablespoon Cajun seasoning

Instructions

  • Preheat oven to 450°F.
  • In a large bowl or directly on the baking sheet, toss the 2 pounds sweet potatoes with 2 tablespoons avocado oil, 1 ½ teaspoon sea salt, and 1 tablespoon Cajun seasoning.
  • Arrange sweet potatoes in single layer on baking sheet, making sure not to overcrowd. Bake until sweet potatoes are tender and golden brown, approximately 20 minutes. Turn with a wide spatula midway.

Notes

Storage: Store leftover fries in an airtight container in the refrigerator for up to 4 days. To reheat, bake at 375°F for 10-15 minutes or air fry at 375°F for 5-8 minutes until crispy.
To freeze: Arrange the fries in a single layer on a baking sheet and freeze until solid. Then, transfer them to a freezer-safe bag or container for up to 3 months. To reheat, bake from frozen at 400°F for 20-25 minutes, flipping halfway through. 
Helpful Tips: 
  1. Cut evenly - To encourage even cooking, cut your sweet potatoes into uniform sizes. This way, they all bake at the same rate and get crispy. 
  2. Don't overcrowd the pan - For the best crispy texture, make sure the fries are spread in a single layer. If needed, use two baking sheets to avoid crowding. 
  3. Broil for the perfect crisp - During the last 3 minutes of cooking, switch your oven to broil to give that golden, crispy finish. Just be sure to keep an eye on them, as they can burn quickly under the broiler. 
  4. No Cajun seasoning - Quickly make your own - use 1 teaspoon smoked paprika, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon cayenne pepper, and ½ teaspoon oregano.
Troubleshooting Tips:
Fries are soggy? It could be because they were overcrowded on the baking sheet. Make sure to spread them out in a single layer to allow for proper crisping. 
Uneven crispiness? To get an even crisp, make sure to flip the fries halfway through cooking. Also, using the broiler for the last few minutes helps achieve that golden brown crisp on top.
