Ingredients

Scale
  • 2 medium-sized sweet potatoes (about 1 pound / 450 grams), peeled and cut into 1/4-inch thick fries
  • 1 to 2 tablespoons olive oil (extra virgin or light)
  • 1 to 2 teaspoons cornstarch (or arrowroot powder for gluten-free)
  • 1/2 teaspoon sea salt (adjust to taste)
  • 1/4 teaspoon freshly ground black pepper
  • 1/2 teaspoon smoked paprika (optional)
  • 1/4 teaspoon garlic powder
  • Optional: chopped fresh parsley or rosemary for garnish

Instructions

  1. Peel and cut the sweet potatoes into 1/4-inch thick fries, about 3 inches long, keeping them as uniform as possible.
  2. Place the cut fries into a large bowl of cold water and soak for at least 30 minutes (up to 1 hour) to remove excess starch.
  3. Drain the water and pat the fries dry completely using a clean kitchen towel or paper towels.
  4. In a dry bowl, sprinkle the cornstarch over the fries and toss gently to coat.
  5. Drizzle with olive oil and mix until every fry is lightly coated.
  6. Add salt, black pepper, smoked paprika, and garlic powder; toss again to distribute seasonings evenly.
  7. Preheat the air fryer to 400°F (200°C) for 3-5 minutes.
  8. Arrange fries in a single layer in the air fryer basket without overcrowding; cook in batches if necessary.
  9. Air fry for 12 minutes, then shake the basket or flip the fries with tongs.
  10. Continue cooking for another 8-10 minutes until fries are golden and crispy, watching closely after 18 minutes to avoid burning.
  11. Remove fries from the basket and let rest for 2 minutes.
  12. Optionally, sprinkle with fresh herbs before serving.

Notes

Soaking the fries in cold water removes excess starch and is key to crispiness. Dry fries thoroughly before coating. Avoid overcrowding the air fryer basket to ensure even cooking. Shake or flip fries halfway through cooking. Use cornstarch or arrowroot powder for a crispy crust. Reheat leftovers in the air fryer at 350°F for 5 minutes to restore crispiness; avoid microwaving.
