Spicy Cajun potato wedges are a flavorful and spicy snack that can be made in an air fryer. Start by cutting the potatoes into wedges and placing them in a bowl. In a separate bowl, mix together melted butter, Cajun seasoning, paprika, garlic powder, salt, and cayenne pepper. Pour the spicy Cajun mixture over the potato wedges and toss until they are evenly coated. Place the seasoned potato wedges in the air fryer basket and cook at 400°F for about 20-25 minutes, or until they are golden brown and crispy. Serve these spicy Cajun potato wedges with a side of ranch or blue cheese dressing for dipping.
