Preheat your oven's broiler. If your broiler has a high and low setting, choose the high setting.
Carefully cut through the top shell of each lobster tail lengthwise, stopping before reaching the tail fan.
Gently pull the shell apart and lift the lobster meat out slightly for better cooking and presentation.
Melt the unsalted butter in a small bowl, then stir in minced garlic, lemon juice, lemon zest, salt, and pepper.
Place the lobster tails on a baking sheet, shell side down, and brush the garlic butter mixture generously over the exposed lobster meat.
Broil the lobster tails for about 8-10 minutes, or until the meat is opaque and slightly browned.
Remove the lobster tails from the oven and let them sit for a minute. Optionally, garnish with fresh parsley and serve with lemon wedges.
For added flavor, sprinkle some paprika or cayenne pepper over the lobster tails before broiling.
