These ultra-crispy sweet potato fries are extra crispy on the outside and tender and flavorful on the inside. These fries are so easy to make and turn out light, delicate, and so satisfying. They are much healthier than the deep-fried version and only use a tiny amount of olive oil. Plus, they are fully cooked to delicious crispness in only 10 minutes in the air fryer.
Wash and peel your sweet potatoes. Cut the potatoes, slice them in half lengthwise with a sharp knife on a cutting board. Then cut each half in half again lengthwise. You will have 4 sections of sweet potato. Cut each section into fries. We want them to be quite small, about ¼-inch wide.
Place sweet potato fries into a large bowl, and cover with water. Let them soak for a minimum of 1 hour or as long as overnight.
Drain the water out and place the sweet potatoes on a towel on the counter. Pat dry with a towel. You want them to be as dry as possible.
Place sweet potatoes in a large bowl. Add about 3 teaspoon of cornstarch, ¾ teaspoon of garlic powder, ¾ teaspoon paprika, and ⅛ teaspoon of black pepper. Use a large spoon and mix up the cornstarch and seasonings into the sweet potatoes. The white cornstarch will disappear. Add 3 tablespoon of olive oil, and mix it up again.
Preheat your air fryer. I set the temperature at 400 degrees Fahrenheit. Add sweet potatoes to the basket of the air fryer. Do not overcrowd the basket. Cook in small batches so that they cook evenly and get really crispy.
Set the cooking time for 10 minutes, and be sure to shake the basket halfway through, at about 5 minutes.
That's it! Serve hot and enjoy!
Notes
Cut the sweet potato fries into evenly sized fries, so they cook evenly.
Make sure to soak the potatoes in water if you want really crispy fries.
Make sure you dry the sweet potatoes really well after they soak in the water.
Do not overcrowd the basket of the air fryer. There needs to be space around the potatoes so that the fries become crispy.
Always add the oil. The oil causes the fries to be ultra-crispy.
Make sure to shake the basket halfway through the cooking time.
All air fryers are not equal. If your fries are not crispy enough, put them back in for another minute or two.
