How to Make Cajun Seafood Boil with Garlic Butter Sauce Recipe
Step 1: Prepare the Flavored Boiling Broth
Start by filling a large stockpot with water and, if you like, a can of beer for that added flavor nuance. Bring it to a lively boil over medium-high heat, then stir in your Cajun seasoning, Old Bay, and hot sauce to kick up the heat and depth. Toss in sliced onions and lemon wedges to infuse the broth with bright citrus and subtle onion sweetness as it simmers for about 15 minutes. This aromatic base is what makes the seafood soak up those bold flavors completely.
Step 2: Add Sausage and Potatoes
Once your broth is fragrant, introduce the andouille sausage and baby potatoes. The sausage will release smoky, spicy oils, while the potatoes absorb the seasoned liquid, becoming tender and flavorful. Let them cook for 15 to 20 minutes—just enough time for the potatoes to reach that perfect fork-tender texture.
Step 3: Cook the Seafood and Corn
Gently add your snow crab clusters, shrimp, and mini corn to the pot, making sure everything is submerged. The seafood cooks quickly—about 5 to 7 minutes—until the shrimp are beautifully pink and the crab is warmed through. This step is crucial so the seafood stays juicy and doesn’t overcook, keeping that ideal texture and sweetness intact.
Step 4: Make the Garlic Butter Sauce for the Cajun Seafood Boil with Garlic Butter Sauce Recipe
While the boil finishes, melt butter in a separate saucepan over medium heat. Add minced garlic and let it infuse the butter with its lovely aroma. Stir in lemon juice, Old Bay seasoning, parsley, Creole Cajun seasoning, smoked paprika, and as much hot sauce as you like. Let this simmer gently for 5 to 7 minutes. The resulting sauce will be rich, seasoned, and perfectly balanced, ready to drench your seafood.
Step 5: Drain and Combine
Use a spider strainer to lift all the boiled ingredients out of the pot, and spread them across a large baking sheet lined with foil or traditional newspaper for that authentic Southern feel. Add hard-boiled eggs if you’re including them, then pour the warm garlic butter sauce over everything and toss gently to coat every piece in that irresistible buttery goodness.
Step 6: Serve Immediately
Serve your Cajun Seafood Boil with Garlic Butter Sauce Recipe piping hot, straight from the tray, inviting everyone to dig in together. The combination of flavors and textures creates a festive, communal experience that’s as much about the joyous gathering as it is about the delicious food.
How to Serve Cajun Seafood Boil with Garlic Butter Sauce Recipe

Garnishes
To elevate the presentation and flavor, sprinkle freshly chopped parsley over the boil for a pop of color and fresh herbaceousness. Extra lemon wedges on the side add a welcome burst of brightness that each guest can squeeze over their serving. For an extra touch of heat, provide additional hot sauce for drizzling.
Side Dishes
This Cajun Seafood Boil with Garlic Butter Sauce Recipe stands proud on its own but pairs beautifully with simple side dishes. A crisp green salad with a tangy vinaigrette cuts through the richness, while crusty bread lets you soak up every last drop of the garlicky sauce. Coleslaw or grilled vegetables also provide a refreshing balance.
Creative Ways to Present
For an unforgettable meal, lay out the seafood boil on a large table covered with butcher paper or newspaper for a casual, hands-on feast. Provide plenty of napkins and seafood crackers if needed. You can also serve it in individual cast iron skillets or on large platters lined with fresh herbs to impress guests at a sitting. Either way, make it about having fun and savoring every bite.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers from the Cajun Seafood Boil with Garlic Butter Sauce Recipe, no worries. Store everything in an airtight container and refrigerate within two hours of cooking. The flavors intensify overnight, making for an even tastier next-day meal.
Freezing
While seafood is best enjoyed fresh, you can freeze the leftover sausage and potatoes separately for up to three months. Avoid freezing cooked shrimp and crab since they tend to become rubbery. Keep the garlic butter sauce frozen in a separate container for best results. When ready to enjoy again, thaw thoroughly.
Reheating
Gently reheat the leftovers on the stovetop over low heat to prevent overcooking the seafood. Add a splash of water or broth to keep things moist and stir in some extra garlic butter sauce to revive the flavors. Avoid using the microwave when possible, as it can toughen delicate seafood textures.
FAQs
Can I use fresh seafood instead of pre-cooked crab?
Absolutely! Fresh crab legs will work wonderfully in this recipe. Just be sure to adjust the cooking time to ensure they cook through without becoming overdone. Fresh crab might need a few more minutes in the boil than pre-cooked options.
Is it necessary to use beer in the boiling broth?
No, the beer is completely optional. It adds a subtle malt flavor that complements the spices nicely but water alone with your seasonings will produce an equally delicious boil.
Can I make this recipe spicier?
Definitely! You can increase the amount of Creole Cajun seasoning and hot sauce to suit your heat preference. Just be mindful of the spice balance to keep the dish flavorful rather than overwhelmingly hot.
What type of potatoes work best for this boil?
Baby red or gold potatoes are ideal because they hold their shape well and soak up the flavors beautifully without turning mushy. Larger potatoes can also be sliced into smaller chunks if preferred.
Can I prepare the garlic butter sauce ahead of time?
Yes, the garlic butter sauce can be made a day ahead and stored in the refrigerator. Reheat gently on the stove before drizzling over the seafood boil to bring back its luscious texture and flavor.

There’s something truly special about bringing everyone together over a steaming, flavorful seafood boil, and this Cajun Seafood Boil with Garlic Butter Sauce Recipe delivers that joy in every bite.
