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 the minced garlic and sauté for 1 minute until fragrant, avoiding browning. Remove from heat and stir in Parmesan cheese, parsley, and red pepper flakes if desired.
05 - Transfer the cooked wings to a large bowl. Pour the garlic Parmesan sauce over the wings and toss until well coated.
06 - Serve immediately with ranch dressing on the side for dipping.
