Use kitchen scissors to cut through the top shell of the lobster tail, stopping at the base of the tail and snipping through the top portion of the meat as you go.

Flip the tail over to the back see-through side and crack the ribs in the center. This will help open the shell.

Open the shell carefully using thumbs and fingers and loosen meat from the shell (remove vein if present). Lift the meat from the shell, keeping it attached at the base. Press the shell together and set the lobster meat over the top. Most of the lobster meat should be sitting on top of the shell.

Place rack in upper third or center of the oven so the meaty tops of your lobster tails will be at least 6 inches from the top heating element. Preheat oven to broil on high heat.

In a small bowl, stir together marinade ingredients: 1 tablespoon parsley, 2 garlic cloves, 1 teaspoon dijon, ¼ teaspoon salt, ⅛ teaspoon pepper, 1 ½ tablespoon olive oil and 1 ½ tablespoon lemon juice.

Place butterflied Lobster Tails into a 9x13 or 8x12 roasting pan. Divide marinade evenly over the tops of each lobster tail and dot each tail all over with ½ tablespoon of butter cut into smaller pieces.

Broil lobster tails on high heat 10-11 min (or according to the lobster tail size). When done, lobster meat should be opaque and white in the center and register 145˚F on an instant read thermometer. Transfer to serving platter and garnish with parsley if desired.

Drain drippings from the roasting pan into a small saucepan and combine with remaining 2 tablespoon butter, bring to a simmer and remove from heat. Pour over lobster tails or divide into ramekins and use as dipping sauce.
