Begin by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper.

In a medium mixing bowl, combine the minced garlic, grated Parmesan cheese, chopped parsley, melted butter, salt, and optional red pepper flakes. Stir until well-combined and creamy.

Add the peeled and deveined shrimp to the mixture and toss gently to coat each shrimp thoroughly.

Arrange the coated shrimp in a single layer on the prepared baking sheet.

Bake for 8 to 10 minutes until shrimp are pink and opaque with slightly golden edges.

Remove from the oven, let rest for a minute, and garnish with additional chopped parsley before serving.
