Cajun Seafood Boil with Garlic Butter Sauce

Why You’ll Love This Recipe

I enjoy this recipe because every bite is packed with smoky, buttery, spicy flavor. The seafood absorbs all the Cajun seasoning while the garlic butter sauce ties everything together beautifully.

I also like how fun and interactive this meal feels. Spreading everything across a large tray and digging in with family or friends turns dinner into an experience. Even though it looks impressive, the process is actually very simple once everything starts boiling.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Seafood Boil

• 3 quarts water
• 3 tablespoons Creole Cajun seasoning
• 1 tablespoon Old Bay seasoning
• Hot sauce, to taste
• 1 medium yellow onion, sliced
• 1 large lemon, cut into wedges
• 12 ounces andouille sausage, sliced into rounds
• 1 pound baby potatoes
• 1 pound pre-cooked snow crab leg clusters
• 1 to 1½ pounds jumbo shrimp, deveined
• 4 to 6 ears sweet corn on the cob
• 4 to 6 hard boiled eggs (optional)

Garlic Butter Sauce

• 1 cup unsalted butter
• 10 cloves garlic, minced
• 2 tablespoons freshly squeezed lemon juice
• 1 tablespoon Old Bay seasoning
• 1 tablespoon chopped parsley
• 1 teaspoon Creole Cajun seasoning
• 1 teaspoon smoked paprika
• Hot sauce, to taste

Directions

1. I start by filling a very large stockpot or Dutch oven with water and bringing it to a boil over medium-high heat.
2. Once boiling, I add the Creole Cajun seasoning, Old Bay seasoning, hot sauce, sliced onion, and lemon wedges. I let the mixture boil for about 15 minutes so the flavors fully develop.
3. Next, I add the sliced andouille sausage and baby potatoes. I cook them for 15 to 20 minutes until the potatoes become nearly fork-tender.
4. I carefully add the crab legs, shrimp, and corn into the pot, making sure everything stays submerged. I continue boiling for another 5 to 7 minutes until the shrimp turns pink and fully cooked.
5. While the seafood cooks, I prepare the garlic butter sauce. In a saucepan over medium heat, I combine the butter, garlic, lemon juice, Old Bay seasoning, parsley, Cajun seasoning, smoked paprika, and hot sauce.
6. I stir the sauce frequently and let it simmer for about 5 to 7 minutes until the butter melts completely and the sauce becomes fragrant.
7. I line a large tray or baking sheet with parchment paper or foil, then transfer all the seafood boil ingredients onto it using a strainer spoon.
8. If using hard boiled eggs, I add them onto the tray as well. Then I pour the warm garlic butter sauce generously over everything.
9. I toss the seafood boil carefully so every piece gets coated in the buttery Cajun sauce.
10. I serve everything immediately with extra lemon wedges on the side.

Variations

I sometimes add lobster tails or mussels when I want to make the seafood boil feel even more luxurious. Crawfish also works wonderfully during crawfish season.

For extra heat, I like adding cayenne pepper or additional hot sauce to the boil and the butter sauce. When I want a milder version, I reduce the Cajun seasoning slightly and let the garlic butter flavor stand out more.

I also enjoy swapping the baby potatoes for red potatoes or adding extra vegetables like mushrooms or broccoli.

storage/reheating

I store leftovers in airtight containers in the refrigerator for up to 2 days. Since seafood tastes best fresh, I try to enjoy it as soon as possible.

For reheating, I prefer warming everything gently in a skillet with extra butter or a splash of broth over medium-low heat. I avoid overheating the shrimp because it can become rubbery.

I do not recommend freezing the fully assembled seafood boil because the texture of the seafood may change after thawing.

FAQs

Can I use frozen seafood?

I can use frozen seafood as long as it is fully thawed before adding it to the boil for even cooking.

What type of pot should I use?

I prefer using a large stockpot or Dutch oven that holds at least 10 quarts so all the ingredients fit comfortably.

Can I make the garlic butter sauce ahead of time?

I can prepare the sauce a few hours ahead and gently reheat it before serving.

How spicy is this seafood boil?

I find the spice level moderate, but I can easily make it milder or hotter depending on how much Cajun seasoning and hot sauce I add.

What should I serve with a seafood boil?

I like serving it with crusty bread, extra lemon wedges, and cold drinks to balance the rich buttery flavors.

Conclusion

I love how this Cajun Seafood Boil brings together bold spices, fresh seafood, and rich garlic butter in one unforgettable meal. The combination of textures and flavors makes every bite exciting, and the shared serving style makes the experience even more fun. It is the perfect recipe for gatherings, weekends, or anytime I want a comforting seafood feast at home.
