Instructions
- Step 1: In a large stock pot, combine beer and water. Bring to a boil, then add bay leaves, Old Bay seasoning, smoked paprika, cayenne pepper, black pepper, thyme, salt, lemon slices, smashed garlic cloves, and sliced onions. Stir and boil for 5 minutes to develop flavor.
- Step 2: Add halved red potatoes and corn pieces. Cook until potatoes are tender but still firm, about 15 minutes. Then add the andouille sausage and cook for another 5 minutes.
- Step 3: Add crab legs and cook for 3 minutes. Next, add lobster tails, mussels, clams, and jumbo shrimp. Cover the pot and boil for 5 to 7 minutes, until mussels and clams open and shrimp turn pink. Stir, then reserve 2 cups of the broth before draining the seafood and vegetables.
- Step 4: Spread newspaper or a large serving tray and arrange the boiled seafood, potatoes, corn, and sausage on top for a casual family-style presentation.
- Step 5: To make the garlic butter sauce, melt butter over medium-low heat in a saucepan. Add diced garlic and cook until fragrant, about 3 minutes. Stir in Cajun seasoning, Old Bay seasoning, red pepper flakes (if using), onion powder, brown sugar, and salt.
- Step 6: Pour in 1 cup of the reserved broth and simmer on low for 3 to 5 minutes until the sauce thickens. For a thinner sauce, add up to 2 cups of broth. Stir in freshly chopped parsley and remove from heat.
- Step 7: Pour the warm garlic butter sauce over the seafood boil. Serve immediately with hot sauce on the side and enjoy!
