Instructions

  1. Step 1: In a large stockpot, bring 6 cups of water to a boil over high heat. Add 3 tablespoons of Cajun seasoning, 2 bay leaves, and 1 tablespoon of salt to the water; stir to combine and let it simmer for 5 minutes to infuse.
  2. Step 2: Add 2 pounds of live crab to the boiling seasoned water, cover, and cook for 12-15 minutes until the crab shells turn bright red and the meat is cooked through.
  3. Step 3: Meanwhile, melt 1/2 cup of unsalted butter in a small saucepan over medium heat. Add 6 minced garlic cloves and cook for 2 minutes until fragrant but not browned.
  4. Step 4: Stir in the juice of 1 lemon, 1 teaspoon of black pepper, and 2 tablespoons of chopped fresh parsley into the garlic butter. Keep warm.
  5. Step 5: Drain the crab well and serve immediately with the warm garlic butter sauce for dipping, garnished with extra parsley if desired.
