Prep the wings: Pat the wings very dry with paper towels. Removing surface moisture is key to crispy skin.
Season the wings: In a large bowl, toss wings with baking powder, salt, pepper, garlic powder, onion powder, and paprika. Coat evenly.
Oven method: Heat oven to 425°F (220°C).
Set a wire rack over a foil-lined baking sheet. Arrange wings in a single layer with a little space between. Bake 35–45 minutes, turning once halfway, until deeply golden and crisp.
Air fryer method: Preheat to 390°F (200°C).
Lightly oil the basket. Arrange wings in a single layer. Cook 20–25 minutes, shaking or flipping halfway, until crisp and cooked through.
Grill method: Preheat grill to medium-high.
Oil grates lightly. Grill wings 18–25 minutes, turning every few minutes, until skin is crisp and meat is done.
Make the garlic butter: In a small pan, melt butter over low heat. Add minced garlic and cook 30–60 seconds until fragrant.
Remove from heat and stir in lemon juice and a pinch of red pepper flakes if you like heat.
Toss with parmesan: Place cooked wings in a large bowl. Pour over the garlic butter and toss. Sprinkle in the grated parmesan and chopped parsley.
Toss again until evenly coated.
Taste and adjust: Add a pinch of salt, extra parmesan, or a squeeze more lemon to brighten the flavor.
Serve hot: Plate with extra parmesan and lemon wedges. These are best right away when the skin is at peak crispness.
