Preheat your oven to 500°F (200°C) for high broiling.

Using sturdy kitchen scissors, cut through the top shell of the lobster tails and gently pry apart the shells, pulling the lobster meat upward.

In a medium mixing bowl, combine melted unsalted butter, minced garlic, chopped parsley, dried pepper flakes, kosher salt, black pepper, and lemon juice. Stir until well incorporated.

Generously brush the garlic butter mixture over the exposed lobster meat.

Place the lobster tails under the broiler for 6-8 minutes until meat is opaque and caramelized.

Serve the lobster tails on a warm plate, drizzling remaining garlic butter sauce over them.
