Prepare your chicken wings by separating the wings into 3 sections with a sharp knife; the drumette, wingette/flat, and the wing tip. The wing tips can be discarded (or reserved to make chicken stock!). Place the chicken in a medium-sized bowl. Melt the butter. Add ⅓ of the melted butter, the garlic and onion powders, and kosher salt. Toss the mixture well.
Place the chicken wings onto the racks of an air fryer, leaving some space between each one. If you have an air fryer with multiple racks, place all the wings into the air fryer. If not, you will likely need to cook the chicken wings in two batches. Set the temperature to 300°F (150°C) for 15 minutes. Cooking the wings at a lower temperature will allow them to get tender.
After the time has passed, increase the heat to 400°F (200°C) for 13-15 minutes to allow the wings to get golden and crispy. If using multiple racks at a time, you may need to rotate the racks halfway through, placing the more browned/crispy rack in a cooler part of the air fryer to allow the other rack to brown.
Add the cooked chicken wings to a clean medium-sized bowl and toss them in the remaining salted butter. Plate the chicken and sprinkle with freshly chopped parsley.
Enjoy hot! Reheat any leftover chicken wings in the air fryer at 400°F (200°C) for 5-6 minutes until hot.
