Equipment

Ingredients

Air Fryer Sweet Potato Fries

  • 1 lb sweet potatoes
  • 1 tbsp avocado oil or extra virgin olive oil
  • ½ tbsp cornstarch
  • 1 tsp kosher salt

Optional Seasonings

  • ½-1 teaspoon seasoning of choice smoked paprika, cinnamon, Za’atar, Creole seasoning, Jerk, Italian seasoning, or your other favorite spice blend.

Instructions

  • Peel the sweet potatoes, then slice them thinly. About ¼-inch thick.
  • Place the sliced potatoes in a mixing bowl and cover with cold water. Soak the potatoes for 10 minutes.
  • Preheat the air fryer to 400°F for 5 minutes before adding the potatoes.
  • Remove the potatoes from the water and transfer them to a clean kitchen towel. Gently pat the potatoes with the towel until they are dry.
  • Transfer the potatoes to a clean and dry mixing bowl. Drizzle them with oil. Use your hands or tongs to gently toss the sweet potatoes until coated.
  • Sprinkle the cornstarch over the potatoes. Use tongs to gently toss them in the cornstarch until covered. Add the salt and toss once more. If using optional spices, add them and toss until coated.
  • Place the sweet potato fries in the air fryer basket or tray and spread them in an even layer, being careful not to overlap or crowd them. Depending on the size of your air fryer, you may need to cook the fries in two batches.
  • Air fry for 10 minutes or until the sweet potato fries are crispy and golden brown yet tender on the inside. Check after 10 minutes, then add up to 2 more minutes for more crispiness if needed. *Note: If you don't want any browning on the sweet potato fries, air fry them for 10 minutes instead of 12 minutes.
  • Cool for a couple of minutes before serving with your favorite dipping sauce.

Notes

Storage Directions
  • Refrigeration: Once cooled to room temperature, the air fried sweet potato fries can be stored in an airtight container in the refrigerator for up to 3 days.
  • Reheating: Warm the fries in an air fryer preheated to 350°F for 2-5 minutes or until hot and lightly crisp.

Recipe Pro-Tips
    • Soak, soak, soak! If you don't do anything else in this air fryer sweet potato fry recipe, soak the potatoes before air frying. Doing so removes excess starch from the potatoes, making them extra crispy. Soak them in cool water for 10 minutes. And be sure to dry them thoroughly before tossing in oil and cornstarch
    • Don't skip preheating. Steadily exposing the fries to a consistently high heat helps them to cook evenly and prevents them from getting soggy.
    • Cook in multiple batches. If your air fryer basket or tray can't accommodate the fries without crowding, cook them in two batches.
    • Flip or shake. Ensure evenly crisp air fry sweet potato fries by gently shaking or turning them once or twice throughout the cooking time if some fries appear to be cooking or browning faster than others.
