Rinse your fresh, deveined shrimp under cold water, then pat them dry thoroughly with paper towels.

In a mixing bowl, combine melted butter with minced garlic, grated Parmesan cheese, black pepper, and optional red pepper flakes. Stir until the mixture is smooth.

Carefully add the prepared shrimp to the bowl and toss gently to coat thoroughly.

Preheat your oven to 400°F (200°C) and line a baking tray with parchment paper.

Spread the marinated shrimp onto the prepared tray in a single layer and bake for 10-12 minutes or until pink and opaque.

Remove from the oven and let cool slightly before serving, garnished with fresh lemon or parsley.
