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 excess moisture for optimal crispiness.
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 wings in a single layer on the prepared wire rack, spacing them apart to allow air circulation and even cooking.
05 - Bake for 25 minutes until the skin begins to crisp and render fat.
06 - Flip wings carefully using tongs. Return to oven and 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 pale golden, taking care not to brown.
08 - Remove saucepan from heat. Stir in grated Parmesan, chopped parsley, chili flakes, and season with salt and pepper to taste.
09 - Transfer crispy wings to a large bowl. Pour garlic Parmesan sauce over wings and toss thoroughly to coat evenly. Serve immediately, garnished with additional Parmesan and parsley if desired.
