This recipe features tender lobster tails grilled with a smoky Cajun butter and finished with a fresh lemon herb butter, delivering bold flavors in a quick and easy dish perfect for special occasions or casual cookouts.

Ingredients

Scale
  • 4 medium-sized lobster tails (68 oz / 170225 g each), thawed if frozen
  • 1/2 cup (115 g) unsalted butter, softened
  • 2 tablespoons Cajun seasoning
  • 2 cloves garlic, minced
  • Zest and juice of 1 lemon
  • 2 tablespoons chopped fresh parsley
  • 1 tablespoon chopped fresh thyme
  • Salt and pepper, to taste
  • 1 tablespoon olive oil, for brushing lobster shells

Instructions

  1. Using sharp kitchen shears, carefully cut down the top of the lobster shell lengthwise, stopping just before the tail fin. Gently pry the shell open and lift the lobster meat, resting it on top of the shell. (About 10 minutes)
  2. In a mixing bowl, combine softened butter, Cajun seasoning, minced garlic, salt, and pepper. Mix well until smooth and fragrant. (5 minutes)
  3. In a separate small bowl, mix softened butter with chopped parsley, thyme, lemon zest, and a squeeze of lemon juice. This will be brushed on after grilling for a fresh finish. (5 minutes)
  4. Preheat the grill to medium-high heat, around 400°F (200°C). Brush the lobster shells lightly with olive oil to prevent sticking. (5 minutes)
  5. Place the lobster tails meat side down on the grill. Grill for about 4 minutes, then flip and spread a generous layer of the Cajun butter over the meat. Grill meat side up for another 4-5 minutes until the lobster is opaque and cooked through (internal temperature 140°F/60°C). (9-10 minutes)
  6. Remove the lobster tails from the grill, then brush the lemon herb butter over the hot lobster meat. The residual heat will melt it perfectly. (2 minutes)
  7. Let the lobster tails rest for a couple of minutes to soak up the flavors before serving.

Notes

Use a meat thermometer to ensure lobster is cooked to 140°F (60°C) for perfect doneness. Avoid overcooking to keep lobster tender. Butter blends can be prepared up to 2 days ahead and refrigerated. For dairy-free option, substitute butter with coconut oil or plant-based butter. If no grill is available, use a grill pan or broiler, adjusting cooking times accordingly.
