Step‑by‑Step Instructions for Cajun Seafood Boil with Garlic Butter Sauce
Step 1: Prepare the Broth
In a large stockpot, bring 4 quarts of water or beer to a rolling boil over high heat. Stir in ¼ cup of Cajun seasoning, 6 smashed garlic cloves, and 2 bay leaves. Let the mixture simmer for about 5 minutes, allowing the flavors to meld beautifully. You’ll know it’s ready when your kitchen is filled with an inviting, fragrant aroma, signaling the start of your Cajun Seafood Boil.
Step 2: Cook the Potatoes
Add 1.5 pounds of halved baby potatoes into the boiling broth, ensuring they are fully submerged. Cook for 10-15 minutes, checking for doneness; they should be fork-tender but not falling apart. Keep an eye on their texture; you can test by piercing one with a fork. This step ensures that your potatoes soak up the bold Cajun flavors that will enhance your seafood boil.
Step 3: Add Sausage
Once the potatoes are slightly tender, introduce 1 pound of chopped andouille sausage to the pot. Stir gently to combine and let it simmer together for about 5 minutes, allowing the sausage to release its smokiness into the broth. You’ll notice the broth taking on a lovely color, signaling the burst of flavors that are coming together for your Cajun Seafood Boil.
Step 4: Introduce Corn and Eggs
Next, carefully add 4 husked corn on the cob pieces and 4 hard-boiled eggs to the pot. Cook for another 10 minutes, ensuring the corn and eggs heat through and the corn becomes bright yellow. The corn should be tender but still crunchy, bringing a delightful sweetness to balance the dish, enriching the fusion of flavor throughout the seafood boil.
Step 5: Finish with Seafood
Now it’s time for the star ingredients! Gently add 2 pounds of deveined jumbo shrimp and 1.5 pounds of pre-cooked snow crab clusters into the pot. Cook for 3-5 minutes, or until the shrimp turn pink and opaque. Stir gently to combine and ensure the seafood cooks evenly. When done, remove the pot from heat to prevent overcooking, and let the savory aromas entice everyone around the table.
Step 6: Mix Garlic Butter
In a separate small saucepan, melt 1 cup of butter over low heat. Add 4 minced garlic cloves and a pinch of Cajun seasoning or Old Bay for an extra flavor boost. Allow the garlic to sauté until fragrant, about 2 minutes, but avoid browning it, as this will create a rich, luxurious garlic butter sauce to drizzle over your Cajun Seafood Boil.
Step 7: Serve
To serve your Cajun Seafood Boil, pour the contents out onto a large platter or spread it across a newspaper-lined table for a fun, communal experience. Drizzle the garlic butter sauce generously over the top, allowing it to soak into the seafood and vegetables. Enjoy immersing yourself in the deliciously messy delight of this festive meal, perfect for sharing with family and friends!

Cajun Seafood Boil with Garlic Butter Sauce Recipe FAQs
What type of shrimp should I use for the Cajun Seafood Boil?
I recommend using jumbo shrimp, as they provide a satisfying bite and flavor. You can choose between fresh or frozen shrimp, but make sure they are deveined to save time during cooking.
How should I store leftover Cajun Seafood Boil?
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Let the seafood boil cool completely before sealing to keep it as fresh as possible. When reheating, do so gently to avoid overcooking the seafood.
Can I freeze Cajun Seafood Boil?
Absolutely! You can freeze the Cajun Seafood Boil in a freezer-safe container for up to 2 months. I recommend portioning it out so you can thaw only what you need. To reheat, thaw it overnight in the fridge, then warm it slowly on the stove over low heat, adding a little water or broth to keep it moist.
What if my seafood boils too long and becomes rubbery?
If you find your seafood turns rubbery, it likely simmered too long. To avoid this, keep a close watch on cooking times, especially when adding shrimp and crab, which only need 3-5 minutes until they are pink and opaque. I suggest using a timer to ensure precision while cooking!
Is this recipe suitable for anyone with seafood allergies?
If you have seafood allergies, it’s best to avoid this recipe entirely, as it features shrimp and crab. However, you could customize the recipe by using only the sausage and vegetables or opting for other proteins like chicken or tofu, along with the renowned garlic butter sauce for flavor.
What should I do if my broth is too salty?
To balance a salty broth, add extra potatoes or corn, which can absorb some saltiness. Additionally, you can add water or a splash more beer to dilute the flavor. Continue tasting until it reaches your desired seasoning level.
