Ingredients
- 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
- 1 – 1 ½ lbs jumbo shrimp, deveined, shell-on or peeled
- 4–6 ears sweet corn on the cob (mini ears preferred)
- 4–6 hard boiled eggs (optional)
- For the garlic butter sauce:
- 1 cup (2 sticks) unsalted butter
- 10 cloves 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
- 1 teaspoon smoked paprika
- Hot sauce, to taste
Instructions
- Step 1: In a large stockpot or Dutch oven (about 10 quarts or larger), combine the water and beer (if using) over medium-high heat and bring to a boil. Add the Creole Cajun seasoning, Old Bay seasoning, and hot sauce to taste. Stir in the sliced onion and lemon wedges. Let the mixture boil for 15 minutes to infuse the flavors.
- Step 2: Add the andouille sausage rounds and baby potatoes to the pot, stirring to combine. Cook for 15-20 minutes or until the potatoes are nearly fork-tender.
- Step 3: Gently add the snow crab clusters, shrimp, and corn on the cob to the pot, ensuring everything is submerged. Stir carefully and continue boiling for 5-7 minutes, until the shrimp turn pink and the seafood is heated through.
- Step 4: While the boil cooks, prepare the garlic butter sauce. In a small saucepan over medium heat, melt the butter and add the garlic, lemon juice, Old Bay seasoning, parsley, Creole Cajun seasoning, smoked paprika, and hot sauce to taste. Simmer for 5-7 minutes, stirring often, until the sauce is well combined and fragrant. Remove from heat.
- Step 5: Line a large baking sheet with foil, parchment paper, or newspaper. Using a spider strainer, transfer the seafood boil contents to the sheet, adding hard boiled eggs if using. Discard the onion and lemon pieces from the pot.
- Step 6: Pour the garlic butter sauce over the seafood boil and toss gently with your hands or tongs to coat everything evenly. If the sauce is too thick, mix in some boil broth to reach your preferred consistency.
- Step 7: Serve the boil immediately, either straight from the baking sheet for a festive communal experience or plated individually. Provide extra lemon wedges and enjoy the bold, garlicky flavors.
Tips & Variations
- Use frozen snow crab clusters if fresh are unavailable; just add a minute or two to the cooking time.
- Swap baby potatoes for red potatoes or fingerlings for a different texture.
- Add smoked sausage instead of andouille for a milder flavor.
- Adjust the heat by varying the amount of hot sauce and Cajun seasoning in both the boil and the garlic butter sauce.
- For extra zest, sprinkle chopped fresh parsley and lemon zest over the finished dish.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stove or in the microwave, adding a splash of water or broth to keep the seafood moist. The garlic butter sauce can be reheated separately and poured over when serving.

Instructions
- Prepare the boil: In an extra large stockpot or Dutch oven (about 10 quarts or larger) set over medium-high heat, combine the water and beer (if using). Bring to a boil, then season with Creole Cajun seasoning, Old Bay seasoning, and hot sauce to taste. Add sliced onion and lemon wedges, stirring to combine.

Stir and simmer for 5-7 minutes until flavors meld and sauce is well combined. Remove from heat.

Pour the garlic butter sauce over the seafood boil, then toss thoroughly with your hands (wear gloves if preferred) to coat everything evenly in sauce.

Notes
- Using beer in the boil adds extra depth and flavor, but you can omit it if preferred.
- Pre-cooked crab legs reduce cooking time and simplify the process.
- Adjust the amount of hot sauce in both the boil and garlic butter sauce to control heat level.
- If you want a thinner garlic butter sauce, add a few ladles of the seafood boil broth while stirring.
- Hard boiled eggs add a nice protein element but are completely optional.
- Wear disposable gloves when tossing to keep hands clean and coated in garlic butter sauce.
- Use a large pot with plenty of capacity to ensure all ingredients cook evenly.
- Serve with plenty of napkins or seafood crackers for cracking crab legs.
