Ingredients

Scale
  • 3 quarts water
  • 1 (12-ounce) can of beer- optional but highly recommended
  • 3 tablespoons Creole Cajun Seasoning– homemade or store-bought
  • 1 tablespoon Old Bay seasoning
  • Hot sauce to taste
  • 1 medium yellow onion roughly sliced into half-moons
  • 1 large lemon cut into wedges- plus more for serving
  • 12 ounces andouille sausage sliced into rounds
  • 1 lb baby potatoes red or gold or a mix of both
  • 1 lb pre-cooked snow crab leg clusters fresh or frozen
  • 11 ½ lbs jumbo shrimp deveined shell-on or peeled
  • 46 ears sweet corn on the cob I use the mini ones
  • 46 hard boiled eggs- optional
  • 1 cup (2 sticks) unsalted butter
  • 10 cloves of garlic finely minced or pressed
  • 2 tablespoons lemon juice freshly squeezed
  • 1 tablespoon Old Bay seasoning
  • 1 tablespoon fresh chopped parsley
  • 1 teaspoon Creole Cajun Seasoning– homemade or store-bought
  • 1 teaspoon smoked paprika
  • Hot sauce to taste

Instructions

  1. Heat a very large pot over medium-high heat and add water and optional beer. Bring to a boil and then add Creole Cajun seasoning, Old Bay seasoning, and hot sauce to taste. Toss in the sliced onion and lemon wedges and stir well, letting it boil for about 15 minutes to infuse flavors.
  2. Add the andouille sausage slices and baby potatoes to the pot and stir them into the boiling liquid. Cook for 15 to 20 minutes until the potatoes become just tender when pierced with a fork.
  3. Carefully add snow crab clusters, shrimp, and corn on the cob to the pot, making sure everything is submerged. Stir gently and boil for an additional 5 to 7 minutes until shrimp turn pink and seafood is heated through.
  4. While seafood boils, melt butter in a separate saucepan over medium heat. Stir in garlic, lemon juice, Old Bay seasoning, parsley, Creole Cajun seasoning, smoked paprika, and hot sauce. Simmer the sauce for about 5 to 7 minutes until fully combined, stirring often.
  5. Remove seafood boil from the pot using a strainer and place it on a foil or parchment-lined baking sheet, adding hard boiled eggs if using, while discarding the onion and lemon pieces. Pour the garlic butter sauce over the seafood mixture and toss well using hands with gloves if desired to fully coat everything.
  6. Serve the seafood boil immediately on the baking sheet or portion onto plates. Optionally serve with extra lemon wedges and enjoy soaking up the butter sauce.
