Crispy Air Fryer Sweet Potato Fries

These air fryer sweet potato fries are a fast side dish with crisp edges, tender centers, and a lightly sweet-spicy seasoning. Cornstarch helps create a drier surface, while a small amount of oil encourages browning without deep frying.

How to Cut Sweet Potato Fries

Cut the sweet potato into evenly sized sticks, about 1/4 inch thick. Consistent sizing matters more than perfect shape because fries of the same thickness finish cooking at about the same time.

How to Make Them Crispy

Combine salt, garlic powder, cayenne, cinnamon, and cornstarch first, then toss the fries with that dry mixture before adding oil. Air fry at 400°F, shaking or tossing once or twice so multiple sides have a chance to brown.

Serving and Storage

Serve the fries immediately with ketchup, ranch, or a creamy dipping sauce. Leftovers can be chilled and reheated in the air fryer until crisp again. They can also be frozen after cooking and reheated straight from the freezer.

Ingredients Method Notes

Ingredients

  

• 1 large sweet potato peeled and cut into 1/4-inch sticks
• 1 tsp cornstarch
• 1/2 tsp fine salt
• 1/4 tsp garlic powder
• 1/4 tsp smoked paprika
• 1/4 tsp ground cinnamon
• 1/8 tsp cayenne pepper optional
• 1 tbsp avocado or olive oil

Method

 

1. Preheat the air fryer to 400°F. Pat the sweet potato sticks dry.
2. Mix cornstarch, salt, garlic powder, paprika, cinnamon, and cayenne. Toss the fries with the dry seasoning, then add oil and toss again.
3. Arrange fries in the air fryer basket in a loose layer. Cook for 10 to 14 minutes, tossing once or twice, until browned at the edges and tender inside.
4. Serve immediately with ketchup, ranch, or your favorite dipping sauce.

Notes

Cut fries as evenly as possible. Thicker pieces need extra time, so begin checking for doneness around 8 minutes.
