01 - Preheat the air fryer to 400°F for 5 minutes to ensure even cooking.
02 - Pat the chicken wings dry using paper towels. In a large bowl, toss wings with olive oil, salt, black pepper, smoked paprika, and garlic powder until fully coated.
03 - Place the wings in a single layer in the air fryer basket. Cook for 24 to 26 minutes, shaking the basket or turning wings halfway through cooking, until they achieve a golden brown and crispy texture.
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 grated Parmesan, parsley, and red pepper flakes if using.
05 - Transfer the cooked wings to a large bowl and pour the garlic Parmesan sauce over them. Toss thoroughly to evenly coat all wings.
06 - Serve immediately alongside ranch dressing for dipping.
