Pat chicken wings dry with paper towels. Arrange them in a bowl and season with salt and pepper.
Preheat your air fryer to 360F. Grease an air-fryer inner basket with olive oil and arrange chicken wings inside in a single layer. Place in the air fryer and cook for 25 minutes, flipping them or shaking the basket halfway through.
If you want the wings to be extra crispy, set the temperature to maximum and cook for an additional 5 minutes or until golden.
While wings are cooking, mix melted butter with minced garlic, chili powder, and red pepper flakes.
When the cooking time ends, remove chicken wings from the air fryer and place in a bowl. Pour seasoned butter over the wings. Add grated Parmesan and parsley. Toss well. Serve immediately and enjoy!
