These sweet potato fries are healthy, delicious and ready in less than 20 minutes from start to finish. These Crispy Air Fryer Sweet Potato Fries are great as a snack, side dish, or even appetizer. 


  • 3 large sweet potatoes, peeled and cut into 1/2 inch fries
  • 3 tablespoons avocado oil
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon sea salt, more to taste
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon smoked paprika
  • fresh thyme leaves, optional for garnish


  1. Put the sweet potatoes in a large bowl and drizzle over the avocado oil. Toss until all of the potatoes are evenly coated. 
  2. In a small bowl, combine the onion powder, garlic powder, salt, pepper, and paprika. Sprinkle the spice mixture over top of the sweet potatoes and toss until evenly coated. 
  3. Heat the air fryer or convection oven to 400°F. Place the sweet potatoes fries in the basket of your air fryer, or on the tray, depending what type of air fryer you have. You may need to cook these in batches.
  4. Cook for 10 to 12 minutes, flip, and cook for an additional 5 minutes, or until cooked through and crispy. 
  5. Garnish with thyme, if using.


  • Storage and reheating: While these Crispy Air Fryer Sweet Potato Fries are best served fresh, they can be refrigerated and then reheated until crispy in the air fryer. 
  • Make them crispier: For a crispier texture, try sprinkling some cornstarch over the sweet potatoes before air frying.
  • Do not overcrowd: Be sure not to overcrowd the air fryer basket or tray, or it can cause the sweet potatoes to steam instead of fry.
  • Cook them in the oven: You can also bake these sweet potato fries in the oven instead of using an air fryer. Simply place them on a baking sheet and bake at 400°F for 25 to 30 minutes, tossing half way through.
