Crispy Air Fryer Sweet Potato Fries

Perfect sweet potato fries made with a simple, light spice coating. The secret to crispy fries is to add a little arrowroot (or starch) to the spice coating, and give the fries space in the air fryer basket for air to circulate around each one. Make in small batches and don't overcrowd the basket!

Ingredients

  • 1 pounds sweet potatoes cut into fry shapes (peeling is optional!)
  • 1/2 tablespoons avocado oil or olive oil
  • 1/2 tablespoon arrowroot starch sub tapioca or organic corn starch
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon paprika

Instructions

  • In a small bowl, combine the arrowroot with the spices.
  • Add half of the sliced sweet potatoes to a large baking tray lined with parchment. Drizzle the fries with avocado oil (or olive oil), and use hands to rub the oil evenly into the potatoes.
  • Sprinkle the sweet potatoes with the spice mixture, then use hands to rub the spice mixture into the oil, evenly coating the potatoes.
  • Preheat the air fryer to 360º F for 5 minutes.
  • Arrange the sweet potatoes in the air fryer basket, leaving space in between each. Allowing space around the potatoes is what crisps them up. If the sweet potatoes are crowded, they will steam instead of dry out and crisp up around the edges. You will most likely need to cook the fries in 2 batches.
  • Air fry the sweet potatoes for 10-12 minutes. Shake the basket in the middle of the cooking time to ensure even browning (this is optional).
  • Repeat with remaining sweet potato fries.
