  • 6 pounds king crab legs split lengthwise

Seasoned Garlic Butter

  • 1 cup salted butter melted
  • 4 Tablespoons basil chopped
  • 8 cloves garlic minced
  • 2 lemons juiced
  • 2 Tablespoons Sweet Rub recipe in notes


  • Preheat. Preheat your grill to 225 degrees F for indirect cooking. 
  • Split the legs. Split your crab legs by cutting them lengthwise using a pair of sharp kitchen shears. Remove any shell fragments. Set the legs split side up on a baking sheet.
  • Season the crab. Combine all ingredients for the seasoned garlic butter in a bowl. Spoon the butter over the exposed meat of the crab. Reserve any additional butter for serving with the finished crab.
  • Grill. Place the split crab legs on the grill grates, shell side down. Close the lid and cook for 25-30 minutes or until the crab is heated through.
  • Enjoy. Serve immediately with more of the hot, melted seasoned butter and fresh lemon wedges.
