01 - Set air fryer to 400°F and allow to preheat for 5 minutes.
02 - Dry chicken wings thoroughly with paper towels. In a large bowl, toss wings with olive oil, salt, pepper, smoked paprika, and garlic powder until evenly coated.
03 - Place wings in a single layer in the air fryer basket. Cook for 24–26 minutes, shaking the basket or turning the wings halfway through, until golden and crisp.
04 - Melt butter in a small saucepan over medium heat. Add minced garlic and sauté for 1 minute until fragrant without browning. Remove from heat, then stir in Parmesan cheese, parsley, and crushed red pepper flakes if using.
05 - Transfer cooked wings to a large bowl. Pour garlic parmesan sauce over wings and toss to coat evenly.
06 - Serve wings immediately alongside ranch dressing for dipping.
