01 - Preheat the air fryer to 400°F for 5 minutes.
02 - Pat the chicken wings dry with paper towels. Toss them in a large bowl with olive oil, salt, black pepper, smoked paprika, and garlic powder until evenly coated.
03 - Arrange the wings in a single layer in the air fryer basket. Cook for 24 to 26 minutes, shaking the basket or turning the wings halfway through, until golden brown and crispy.
04 - Melt the butter in a small saucepan over medium heat. Add minced garlic and sauté for 1 minute until fragrant but not browned. Remove from heat, then stir in Parmesan cheese, parsley, and red pepper flakes if using.
05 - Transfer cooked wings to a large bowl. Pour the garlic parmesan sauce over them and toss to coat evenly.
06 - Serve immediately accompanied by ranch dressing for dipping.
