Add a kick to your sweet potato fries by making them spicy Cajun-style. Start by processing the sweet potatoes in a food processor to create thin fries. In a bowl, combine Cajun seasoning, paprika, garlic powder, salt, and pepper. Toss the sweet potato fries in olive oil, then coat them with the spice mixture. Air fry until crispy and serve with a spicy dipping sauce for an extra burst of flavor.
