There is something about a big Cajun Seafood Boil with Garlic Butter Sauce spread across the table that instantly feels like a celebration. The first time I made this at home, I covered my table with parchment paper, dumped everything right in the center, and told everyone to dig in. It was messy, loud, and honestly one of the most fun dinners we have had in a long time.
This Cajun Seafood Boil with Garlic Butter Sauce is bold, buttery, and packed with that classic Southern spice. It looks impressive, but it is surprisingly simple.

INGREDIENTS
Here is everything you need. I like to prep everything before I start because once the pot is boiling, things move quickly.

Seafood And Protein
- 1 pound large shrimp, peeled and deveined
- 1 pound snow crab legs
- 1 pound smoked sausage, sliced
Vegetables
- 1 ½ pounds baby potatoes
- 4 ears corn, cut into halves
Boil Seasoning
- 1 tablespoon salt
- 1 tablespoon Cajun seasoning
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- ½ teaspoon black pepper
Garlic Butter Sauce
- 1 cup unsalted butter
- 6 cloves garlic, minced
- 1 tablespoon Cajun seasoning
- 1 tablespoon lemon juice
- 1 tablespoon chopped fresh parsley
PREPARATION
Step 1: Boil The Potatoes
Fill a large stockpot with water and bring it to a boil. Add the salt, Cajun seasoning, paprika, garlic powder, and black pepper.
Add the baby potatoes first. They need the longest cooking time. Boil for about 10 to 12 minutes.
Step 2: Add The Corn And Sausage
Add the corn and sliced sausage to the pot. Boil for another 5 to 7 minutes.
The kitchen will already start smelling amazing at this point.
Step 3: Add The Seafood

Add the crab legs and shrimp last. Shrimp cook very quickly, usually in about 3 to 4 minutes. As soon as they turn pink and opaque, they are done.
Do not overcook. I learned that the hard way once and ended up with rubbery shrimp. We still ate it, but I was not thrilled.
Drain everything carefully once cooked.
Step 4: Make The Garlic Butter Sauce
In a saucepan over medium heat, melt the butter.
Add the minced garlic and cook for about 1 to 2 minutes until fragrant. Stir in the Cajun seasoning and lemon juice.
Turn off the heat and mix in chopped parsley.

CONSEILS AND SUGGESTIONS
This Cajun Seafood Boil with Garlic Butter Sauce is very flexible. Here are some tips that make it even better.
Adjust The Spice Level
If you prefer mild, reduce the Cajun seasoning slightly. If you love heat, add a pinch of cayenne pepper to the garlic butter sauce.
Add More Seafood
You can include mussels, clams, or lobster tails. Just adjust cooking times accordingly.
Do Not Crowd The Pot
If your pot is too small, cook in batches. Overcrowding lowers the water temperature and can affect cooking time.
Make It A Party
I like serving this family style. Lay everything out on parchment paper and let everyone grab what they like. It turns dinner into an event.
