Pat the chicken wings and flats dry with a paper towel and then place them in a large bowl. Add the Old Bay seasoning, garlic powder, onion powder, smoked paprika, and baking powder over the wings (about 1 teaspoon per pound).
Drizzle with olive oil and toss until the wings are evenly coated with the seasoning mixture.
Preheat the air fryer to 390°F (200°C) for 5 minutes and then arrange the seasoned wings in a single layer in the preheated air fryer basket, ensuring they are not overcrowded. Air fry the wings for 25-30 minutes until they are crispy and golden brown, shaking the basket halfway through cooking for even browning.
In a small bowl, combine the melted unsalted butter with minced garlic.
Once cooked, transfer the wings to a large bowl. Pour the buttery garlic sauce over the cooked wings, tossing them gently to coat evenly. Sprinkle Parmesan cheese and chopped parsley over the wings and toss again to ensure an even coating.
Transfer the wings to a serving platter and season with salt and black pepper to taste. Serve your air fryer garlic parmesan chicken wings hot as a delicious appetizer or main dish with a side of your favorite sauce.
