Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or a wire rack placed over the baking sheet for maximum crispiness.
Pat the chicken wings completely dry using paper towels. Removing excess moisture helps create crispier skin.
In a large mixing bowl, combine the olive oil, baking powder, garlic powder, smoked paprika, kosher salt, and black pepper.
Add the chicken wings and toss until every piece is evenly coated.
Arrange the wings in a single layer on the prepared baking sheet, leaving about 2 inches between each piece. Use two baking sheets if necessary to avoid overcrowding.
Bake for 35 minutes, flipping the wings halfway through cooking so both sides become evenly golden and crispy.
While the wings bake, prepare the garlic Parmesan sauce. In a medium bowl, stir together the melted butter, minced garlic, grated Parmesan cheese, and chopped parsley until well combined.
Remove the baked wings from the oven and transfer them to a large clean bowl.
Pour the garlic Parmesan sauce over the wings and gently toss until each wing is completely coated.
Return the coated Crispy Garlic Parmesan Wings to the baking sheet and bake for another 5 minutes so the sauce adheres to the chicken and the garlic becomes fragrant.
Remove from the oven and garnish generously with additional Parmesan cheese and fresh parsley before serving immediately
