Ingredients

  • - 4 lobster tails 5–6 oz each
  • - 2 tablespoons olive oil
  • - Salt to taste
  • - Cracked black pepper to taste
  • - Lemon wedges for serving
  • For the Cajun Garlic Butter Sauce:
  • - 1 cup salted butter
  • - 1/2 onion diced
  • - 4 cloves garlic minced
  • - 2 tablespoons Creole seasoning
  • - 1/2 tablespoon onion powder
  • - 1 tablespoon brown sugar
  • - 1 teaspoon red pepper flakes adjust to taste
  • - 1/2 cup chicken stock
  • - 1 tablespoon lemon juice
  • - 1 tablespoon fresh parsley chopped

Instructions

  • Use kitchen shears to cut through the top shell of each lobster tail, from the open end to just before the tail fan.
  • Gently pull the shell apart and lift the meat out, resting it on top of the shell. Rinse lightly under cool water and pat dry.
  • Brush lobster meat with olive oil, then season with salt and cracked black pepper. Set aside.
  • Preheat grill to medium-high heat (around 400°F). Clean and oil the grates.
  • In a saucepan over medium heat, melt the butter. Add diced onion and sauté until translucent (3–4 minutes).
  • Add garlic and cook for 1 minute more.
  • Stir in Creole seasoning, onion powder, brown sugar, and red pepper flakes.
  • Pour in chicken stock and bring to a light simmer. Add lemon juice and chopped parsley. Keep warm for basting.
  • Place lobster tails on the grill meat side down for 4–5 minutes to sear and get char marks.
  • Flip and cook shell side down for another 4–6 minutes, or until meat is opaque and firm.
  • During the last few minutes of cooking, baste generously with Cajun garlic butter sauce.
  • Remove from grill and place on a serving platter. Spoon extra sauce over the top.
  • Garnish with lemon wedges and extra parsley. Serve hot with your favorite sides.
