01 - Preheat oven to 450°F. Line a large baking sheet with parchment paper or foil and set a wire rack on top. Lightly grease the rack with cooking spray or oil.
02 - Pat the chicken wings completely dry with paper towels, removing any excess moisture to ensure proper crisping.
03 - In a large bowl, combine baking powder, kosher salt, black pepper, garlic powder, and smoked paprika. Add wings and toss until evenly coated with the spice mixture.
04 - Place the seasoned wings in a single layer on the prepared wire rack, ensuring adequate spacing between pieces for optimal air circulation and even cooking.
05 - Bake for 25 minutes until the wings begin to brown and the skin starts to render fat.
06 - Flip each wing using tongs and return to the oven. Bake for an additional 20 minutes until golden brown and crispy throughout.
07 - While wings finish baking, melt butter in a small saucepan over medium-low heat. Add minced garlic and sauté for 1-2 minutes until fragrant and lightly golden, being careful not to burn.
08 - Remove saucepan from heat. Stir in grated Parmesan cheese, chopped parsley, and chili flakes. Season with additional salt and pepper to taste.
09 - Transfer the crispy baked wings to a large clean bowl. Pour the garlic Parmesan sauce over the wings and toss thoroughly to coat each piece evenly.
10 - Plate the wings immediately while hot. Garnish with additional grated Parmesan and fresh parsley if desired. Serve with celery sticks and blue cheese or ranch dressing.
