When it comes to a Cajun Seafood Boil with Garlic Butter Sauce Recipe, fresh seafood and a well-seasoned boil are the stars. Each ingredient plays its part to create layers of flavor that complement each other perfectly. Here’s a peek at what you need and why these choices matter.
- Water & Beer: The beer adds a subtle depth to the boil’s broth, but plain water works just fine if you prefer.
- Creole Cajun Seasoning: Key to that authentic spicy kick; homemade or good quality store-bought works great.
- Old Bay Seasoning: Balances the heat and adds that classic seafood boil flavor you expect.
- Hot Sauce: Adds customizable heat — I love using my favorite Louisiana hot sauce here.
- Yellow Onion & Lemons: They infuse a sharp sweetness and bright citrus to the broth as it cooks.
- Andouille Sausage: Adds smoky, spicy richness that deepens the flavor profile.
- Baby Potatoes: These soak up the seasoning beautifully and add hearty texture to your boil.
- Snow Crab Leg Clusters & Shrimp: Fresh or frozen, these seafood staples make the boil feel like a coastal retreat.
- Sweet Corn on the Cob: Provides sweet crunch and a lovely contrast to the spices.
- Hard Boiled Eggs (optional): A fun southern tradition that adds a rich, creamy bite.
- Unsalted Butter & Garlic: The star of the garlic butter sauce that you’ll pour over everything — trust me, it makes all the difference!
- Lemon Juice, Parsley & Smoked Paprika: These bring brightness, color, and smoky depth to the butter sauce.
Variations
I’ve played around with this Cajun Seafood Boil with Garlic Butter Sauce Recipe over the years, and one of the best parts is how you can make it your own — don’t hesitate to experiment a little. Here are some ideas to inspire you.
- Variation: I often swap out snow crab for lobster tails or mussels when they’re in season, which amp up the luxury factor without much extra effort.
- Make it Spicier: Add extra cayenne pepper or use a hotter hot sauce if you love a serious kick — just remember to taste as you go.
- Vegetarian Version: Use hearts of palm or artichoke hearts, and swap the seafood for hearty mushrooms in the boil — then slather in garlic butter to keep all the richness.
- Extra Veggies: I like tossing in sliced bell peppers or mushrooms for more variety and color in the pot.
How to Make Cajun Seafood Boil with Garlic Butter Sauce Recipe
Step 1: Build Your Flavorful Boil Base
Start by grabbing a large stockpot or Dutch oven — you’ll want something big enough to fit everything comfortably. I like to add water and a can of beer (the beer adds an amazing depth, but it’s completely optional). Bring the liquid up to a rolling boil over medium-high heat. Then toss in your Creole Cajun seasoning, Old Bay, and some hot sauce. Stir well so those flavors start to meld together. Once everything’s mixed, add the onion slices and lemon wedges. Let it all boil for about 15 minutes to really infuse the broth. This step is a game-changer — trust me on the flavor you’ll build here!
Step 2: Cook the Andouille and Potatoes
Next, carefully add in your sliced andouille sausage and baby potatoes. Give everything a gentle stir so they’re fully submerged and able to soak up the spices. Cook for about 15-20 minutes, depending on your potatoes, until they’re just fork-tender. This part is where the sausage imparts that smoky goodness into the pot, and the potatoes start absorbing all that flavorful broth. Don’t rush this — the potatoes need time to soften without getting mushy.
Step 3: Get Your Seafood and Corn in the Pot
Gently nestle your snow crab leg clusters, shrimp, and ears of corn into the pot. Make sure everything stays submerged so it cooks evenly — you might have to use a wooden spoon to nudge things around. Let the boil continue for about 5-7 minutes, until your shrimp turn that gorgeous pink color. This is also a great time to start making the garlic butter sauce on the side, so everything finishes together.
Step 4: Whip up the Garlic Butter Sauce
In a small saucepan over medium heat, melt your unsalted butter and add finely minced garlic, fresh lemon juice, Old Bay, Creole Cajun seasoning, smoked paprika, parsley, and as much hot sauce as you like. Stir continuously and let it simmer gently for 5-7 minutes to fully infuse the butter with those incredible flavors. This sauce will be the luscious final touch that brings everything together in that addictive garlic-buttery way I absolutely love.
Step 5: Assemble, Toss, and Serve
Use a spider strainer or tongs to carefully remove the seafood boil from the pot, leaving behind the onion and lemon pieces we don’t want on the plate. Spread everything out on a large baking sheet lined with foil or parchment paper (or if you’re feeling traditional, newspaper totally works!). Add the optional hard-boiled eggs on the side. Then comes the best part — pour that garlic butter sauce generously over the entire spread and toss everything gently by hand (gloves help here!). Make sure each piece is beautifully coated. Serve immediately with extra lemon wedges for squeezing. Prepare for your family and friends to go crazy for this!
Pro Tips for Making Cajun Seafood Boil with Garlic Butter Sauce Recipe
- Freshness Matters: Whenever possible, use fresh seafood—it makes a noticeable difference in both texture and taste.
- Don’t Overcook Seafood: Shrimp cook fast and turn rubbery if left too long—watch their color change closely as your timer runs out.
- Adjust Spice Levels Gradually: It’s easier to add heat than mellow it out, so start with less hot sauce and seasonings, then taste and add as needed.
- Use Gloves for Tossing: It keeps your hands clean and saves you from garlic breath—plus, you can really coat every bite perfectly.
How to Serve Cajun Seafood Boil with Garlic Butter Sauce Recipe
Garnishes
I love garnishing with extra fresh parsley for a pop of color and brightness, plus plenty of lemon wedges for that fresh citrus zing that cuts through the richness. Sometimes I sprinkle a little more smoked paprika on top for visual appeal and a subtle smoky aroma—it really elevates your presentation.
Side Dishes
My go-to sides to serve alongside this Cajun Seafood Boil are simple but flavorful—think buttery crusty bread for sopping up the garlic butter sauce, and a crisp green salad with a light vinaigrette to refresh your palate. I also adore serving coleslaw on the side for a crunchy, tangy contrast.
Creative Ways to Present
For special occasions, I like spreading the boil out over a large rustic wooden board or a newspaper-lined table, sealed with butcher paper. It turns dinner into an event! Add small bowls of extra garlic butter sauce and cocktail sauce so guests can customize their bites. It’s messy, festive, and absolutely unforgettable.
Make Ahead and Storage
Storing Leftovers
I always store leftovers in airtight containers in the fridge. To keep the seafood tender and prevent it from drying out, I drizzle a little extra melted butter over the top before sealing. This helps keep the flavors fresh for up to 2 days.
Freezing
Freezing seafood boils is tricky because seafood can become rubbery after thawing. If you do freeze, I recommend removing the seafood from the broth and freezing separately in freezer bags, then reheating gently. The potatoes and sausage freeze better and can be reheated without losing texture.
Reheating
To reheat, I gently warm leftovers in a covered skillet over low heat with a splash of water or broth to bring back moisture. Reheating in the garlic butter sauce helps restore flavor and richness. Avoid the microwave if you can; it tends to dry out shrimp and crab.
FAQs
-
Can I use frozen seafood for this Cajun Seafood Boil with Garlic Butter Sauce Recipe?
Yes! Using frozen seafood like snow crab clusters and shrimp works perfectly fine — just make sure to thaw them completely in the fridge before adding them to the boil. This helps them cook evenly and soak up all those fantastic spices.
-
How spicy is the Cajun Seafood Boil with Garlic Butter Sauce Recipe?
The heat level is completely adjustable. I recommend starting with a moderate amount of Cajun seasoning and hot sauce, then tasting as you go. You can always add more if you want it extra spicy — it’s all about personal preference!
-
What if I don’t have andouille sausage?
No worries! You can substitute with kielbasa, smoked sausage, or any spicy sausage you like. It adds that smoky, savory kick that pairs beautifully with the seafood.
-
Can I make the garlic butter sauce ahead of time?
Absolutely! You can prepare the garlic butter sauce a day ahead and gently reheat it when you’re ready to serve. Just be sure to stir frequently while warming so the garlic doesn’t burn.

Ingredients
For the Cajun Seafood Boil:
- 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)
- 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 size 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 freshly squeezed lemon juice
- 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
- Prepare the boil: In a large stockpot or Dutch oven (around 10 quarts or larger) over medium-high heat, combine the water and beer (if using) and bring to a boil. Season the liquid with Creole Cajun seasoning, Old Bay seasoning, and hot sauce to taste. Add the sliced onion and lemon wedges, stirring well. Allow the mixture to boil for 15 minutes to infuse the flavors.
- Add the andouille and potatoes: Carefully add the sliced andouille sausage and baby potatoes to the boiling pot. Stir to combine and continue cooking for 15-20 minutes, or until the potatoes are nearly fork-tender.
- Add the seafood and corn: Gently place the snow crab leg clusters, shrimp, and corn on the cob into the pot, ensuring they are fully submerged. Stir carefully to mix. Boil for an additional 5-7 minutes, until the shrimp turn pink and the seafood is cooked through.
- Make the garlic butter sauce: While the seafood cooks, in a separate small saucepan over medium heat, combine the butter, minced garlic, lemon juice, Old Bay seasoning, chopped parsley, Creole Cajun seasoning, smoked paprika, and hot sauce to taste. Stir frequently as the butter melts and the sauce melds together, about 5-7 minutes. Remove from heat once fully blended.
- Assemble the seafood boil with sauce: Line a large baking sheet with foil, parchment, or newspaper. Using a spider strainer, carefully remove the seafood boil ingredients from the pot and spread them on the baking sheet, adding the hard boiled eggs if using. Discard the onion and lemon pieces from the broth. If you prefer a thinner garlic butter sauce, stir in some of the cooking broth to adjust consistency. Pour the garlic butter sauce over the seafood and potatoes on the tray, then toss thoroughly with hands (wearing disposable gloves if preferred) to coat every piece in sauce.
- Serve the seafood boil: Serve immediately, either family-style from the baking sheet for a casual, fun experience or plated individually if preferred. Garnish with extra lemon wedges for squeezing over the seafood. Be sure to enjoy the rich garlic butter sauce to the last drop!
Notes
- Using beer in the boiling liquid adds depth of flavor but can be omitted if desired.
- Pre-cooked snow crab helps speed up cooking; if using raw, cook accordingly until done.
- Keep shrimp shelled if you enjoy peeling as you eat, or peel ahead for convenience.
- Hard boiled eggs add extra protein and are optional.
- Adjust hot sauce amounts in both the boil and the garlic butter sauce to your preferred spice level.
- Use disposable gloves when tossing the seafood in sauce for less mess and easier cleanup.
- Leftover broth can be strained and used as a flavorful base for soups or gumbo.
