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

Rinse the fresh shrimp under cold water, remove the shells and devein, then pat dry.

In a bowl, combine melted butter, minced garlic, grated Parmesan, and black pepper. Add red pepper flakes if desired.

Toss the shrimp in the garlic-Parmesan mixture until well-coated.

Arrange the shrimp on the baking tray with space between each for even cooking.

Bake in the oven for 10-12 minutes until shrimp turn pink and opaque.

Serve immediately with lemon juice and fresh parsley for a burst of flavor.
