Preheat your oven to 500°F (200°C). Prepare a baking sheet lined with aluminum foil or parchment paper.

Carefully cut along the top shell of the lobster tails with kitchen scissors and gently lift the lobster meat out.

In a mixing bowl, combine melted butter, minced garlic, chopped parsley, red pepper flakes, salt, and black pepper. Whisk until well blended.

Brush the garlic butter mixture generously over the lobster tails and reserve some for serving later.

Place lobster tails on the baking sheet and broil for about 6-8 minutes, until the meat is opaque.

Remove from oven, plate, drizzle with reserved butter, and garnish with additional parsley if desired.
