Start by rinsing the fresh shrimp under cold water to ensure they're clean. Remove the shells and devein them.

In a mixing bowl, combine melted butter, fresh minced garlic, and grated Parmesan cheese. Add black pepper and red pepper flakes, stir until well blended.

Carefully add the shrimp into the bowl with the marinade and toss gently to coat evenly.

Preheat your oven to 400°F (200°C). Arrange the coated shrimp on a parchment-lined baking sheet in a single layer.

Bake the shrimp for 10-12 minutes, until they turn pink and the Parmesan crust is golden brown.

Remove them from the oven, let them rest for a minute, and squeeze fresh lemon juice before serving.
