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 corn ears work well)
- 4-6 hard boiled eggs (optional)
- 1 cup (2 sticks) unsalted butter
- 10 cloves garlic, finely minced or pressed
- 2 tablespoons freshly squeezed lemon juice
- 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 an extra large stockpot or Dutch oven (about 10 quarts or larger), combine water and beer (if using) over medium-high heat and bring to a boil.
- Step 2: Season the boiling liquid with Creole Cajun seasoning, Old Bay seasoning, and hot sauce to taste. Add sliced onion and lemon wedges, stir well, and let boil for 15 minutes to infuse flavors.
- Step 3: Carefully add the andouille sausage slices and baby potatoes to the pot. Stir to combine and cook for 15-20 minutes, until potatoes are just fork-tender.
- Step 4: Gently add the snow crab clusters, shrimp, and corn to the pot. Ensure all ingredients are submerged, stir gently, and continue boiling for 5-7 minutes until shrimp turn pink.
- Step 5: While the boil cooks, prepare the garlic butter sauce. In a small saucepan over medium heat, combine butter, garlic, lemon juice, Old Bay seasoning, parsley, Creole Cajun seasoning, smoked paprika, and hot sauce to taste. Simmer, stirring often, until butter melts and the sauce is well blended, about 5-7 minutes. Remove from heat.
- Step 6: Line a large baking sheet with foil, parchment paper, or newspaper. Using a spider strainer, transfer the boil ingredients to the baking sheet, including hard boiled eggs if using. Discard onion and lemon bits from the pot.
- Step 7: Pour the garlic butter sauce over the boil ingredients. Toss everything by hand (use disposable gloves if desired) to coat completely with sauce.
- Step 8: Serve immediately with additional lemon wedges. Guests can enjoy the fun of grabbing their favorite bites straight from the baking sheet or you can plate individually.
Tips & Variations
- For a thinner garlic butter sauce, stir in some of the broth from the seafood boil until you reach your desired consistency.
- Use fresh seafood when possible for the best flavor, but frozen pre-cooked crab and shrimp work well and save time.
- Add extra vegetables like mushrooms or bell peppers to the boil for more variety.
- Adjust the heat by varying the amount of hot sauce and Cajun seasoning according to your taste.
- Serve with crusty bread or French fries to soak up the flavorful garlic butter sauce.
Storage
Store leftover seafood boil in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm in a skillet or microwave until heated through; be careful not to overcook the seafood. Garlic butter sauce can be stored separately and reheated gently before serving.
