Pat the sweet potato sticks completely dry with paper towels to remove excess moisture.
In a large bowl, toss the sweet potato sticks with olive oil until evenly coated.
Add garlic powder, paprika, salt, black pepper, and cayenne pepper, tossing until the fries are evenly seasoned.
Preheat the air fryer to 380°F for 3 minutes.
Arrange the fries in a single layer in the air fryer basket, working in batches if necessary to avoid overcrowding.
Cook for 18-20 minutes, shaking the basket every 5 minutes to ensure even cooking, until the fries are golden brown and crispy.
Serve immediately with your favorite dipping sauce.
