  • 8 tbsp unsalted butter
  • 1/4 cup old bay seasoning
  • 1 onion roughly chopped
  • 6 garlic cloves smashed
  • 2 lemons quartered
  • 2 bay leaves
  • 2 tsp garlic powder
  • 2 tsp onion powder
  • 1 tsp paprika
  • 1 tsp oregano
  • 12 cups water
  • salt and pepper to taste

Garlic Butter Sauce

  • 8 tbsp unsalted butter
  • 1/2 onion diced
  • 4 garlic cloves finely minced
  • 2 tsp paprika
  • 1 tsp old bay seasoning
  • 1 tbsp hot sauce
  • 1 tsp lemon juice


  • Add 8 tbsp butter and onions to a large stockpot and cook over medium-high heat for 2-3 minutes.
  • Stir in the garlic, old bay seasoning, garlic powder, onion powder, oregano, paprika, lemons, bay leaves, and 12 cups of water. Once the water comes up to a boil you'll want to start cooking the seafood separately. 
  • Add the potatoes and cook them for 14 minutes or until fork-tender. Remove them once cooked, and set aside.
  • Add the lobster and cook for 5-8 minutes, add the crab and corn and cook for 5 minutes. Cook the sausage for 2 minutes and the shrimp for 1 minute.
  • Once you're done cooking the seafood in batches, get started on the lemon garlic butter sauce. Add the butter to a skillet and cook over medium heat. Add the onions and cook for 2 minutes.
  • Stir in the fresh minced garlic, old bay seasoning, paprika, lemon juice, and hot sauce. Check for seasoning and pour the sauce over the seafood or place it in a small bowl. Dip the seafood into the sauce and enjoy! 



  • Because shrimp cook super quickly and potatoes take a long time to cook, you cannot simply dump all of the ingredients in the stockpot. Unless 2 items cook for the same period of time, it must be cooked separately.
  • Add some clams, mussels, crawfish, or a meaty fish like swordfish.
  • Make sure to adjust seasoning to your liking. If you like it spicy, add some cayenne pepper and red pepper flakes. If you like it saltier, add more salt.
  • Have your seafood thawed and ready to go before the seafood broth starts boiling.
  • Place all of the cooked seafood, potatoes, and corn in an oven bag with all of the lemon butter garlic sauce and shake the bag. That will help the sauce coat the seafood well.
