Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper.

Pat the chicken wings dry using paper towels, removing any excess moisture.

In a mixing bowl, combine cornstarch, garlic powder, onion powder, coarse kosher salt, ground black pepper, and optional red pepper flakes. Whisk until evenly mixed.

Toss chicken wings in the cornstarch mixture, ensuring they are evenly coated. Shake off excess coating and arrange in a single layer on the baking sheet.

Bake the wings for 40 to 50 minutes, flipping halfway through for even cooking.

Set your oven to broil and broil the wings for 2 to 3 minutes per side for added crispiness.

In a saucepan, melt unsalted butter over medium heat, adding minced garlic and parsley. Stir until fragrant, then remove from heat and mix in grated Parmesan cheese.

Transfer the baked wings to a large mixing bowl, drizzle with the garlic parmesan sauce, and toss until well-coated.
