Preheat your oven to 400°F (200°C).

Rinse the shrimp under cold water and pat dry with paper towels.

In a mixing bowl, combine melted butter or olive oil, minced garlic, grated Parmesan cheese, black pepper, and red pepper flakes.

Add the prepared shrimp to the bowl with the marinade and toss gently.

Arrange the marinated shrimp on your prepared baking tray.

Place the baking tray in the preheated oven and roast the shrimp for 10-12 minutes.

Once cooked, serve immediately, optionally garnished with parsley or lemon.
