Craving sweet potato fries? The air fryer delivers crispy fries without all the oil of deep frying. Cornstarch is the secret ingredient for guaranteed crispiness. Here's how to make them.

  • 2 medium sweet potatoes
  • 1 tablespoon cornstarch
  • 1 tablespoon olive oil
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • Optional: 1/4 teaspoon smoked paprika or cinnamon (pick a direction)

  1. 01Peel the sweet potatoes. Cut into sticks about 1/4 inch wide and 3 inches long. Consistency matters more than precision. Even cuts mean even cooking.
  2. 02Soak the sticks in cold water for 20 to 30 minutes. This draws out excess starch and is the difference between crispy fries and soft sweet potato sticks.
  3. 03Drain and pat VERY dry. Wet sweet potato fries steam instead of crisp.
  4. 04Toss with cornstarch first, making sure every fry is coated. Then add oil and seasonings and toss again.
  5. 05Ready for the air fryer. Single layer, don't crowd, shake frequently.
Cornstarch is mandatory. Sweet potatoes have more sugar and moisture than regular potatoes, which makes them want to go soft instead of crispy. The cornstarch creates an outer shell that crisps while the inside stays tender. Skip it and you get sweet potato sticks. Use it and you get sweet potato fries. The cold water soak matters too. Do both.

Stores 3 days. Reheat at 400°F (200°C) for 3-4 minutes. They soften in the fridge, so the high temp blast is needed to re-crisp.
