Use kitchen scissors to cut through the top shell of the lobster tail, stopping at the base. Carefully crack the ribs to expose the lobster meat, and gently butterfly the lobster for even cooking.
In a small bowl, mix together parsley, garlic, dijon, salt, pepper, olive oil, and lemon juice until well combined. This will be your marinade.
Place the prepared lobster tails in a roasting pan. Generously top each tail with the marinade and place small dots of butter on top.
Broil the lobster tails on high for 10-11 minutes, or until the meat becomes opaque and a thermometer reads 145˚F.
Drain the roasting pan drippings into a saucepan. Combine with the remaining butter, simmer briefly, and serve over the lobster or as a dipping sauce.
Notes
For best results, use fresh ingredients and be cautious of overcooking.
Serve with a fresh salad and bread for a complete meal.
