Begin by washing and thoroughly drying the chicken wings, ensuring they're completely pat dry. Coat the wings in olive oil, then season with a mixture of seasoning salt, black pepper, and garlic powder. In a shallow dish, combine flour with seasoning salt, garlic powder, black pepper, and onion powder. Coat the chicken wings evenly in this mixture, then refrigerate for 30 minutes. While the wings chill, prepare the garlic parmesan sauce by melting butter in a pot over medium heat.
