Step‑by‑Step Instructions for Homemade Cajun Seafood Boil Recipe
Step 1: Make the seasoning blend
In a medium bowl, combine Old Bay seasoning, smoked paprika, onion powder, garlic powder, cayenne pepper, red pepper flakes, dried thyme, black pepper, ground mustard, celery seed, and ground coriander. Stir well to ensure even distribution. Set the seasoning blend aside, as it will be essential for infusing flavor into your homemade Cajun seafood boil.
Step 2: Prepare boiling water
Fill a large stockpot about halfway with water and place it over high heat. Allow the water to come to a vigorous boil, which may take around 60 to 90 minutes depending on your stovetop. Look for that rolling boil before adding any ingredients, as this will create the perfect cooking environment for your seafood and veggies.
Step 3: Add flavor ingredients
Once the water is boiling, carefully stir in kosher salt, bay leaves, quartered onions, smashed garlic cloves, Louisiana-style hot sauce, and lemon slices. Then, sprinkle in your prepared seasoning mix, stirring to combine. This aromatic blend will create a flavorful base for your homemade Cajun seafood boil that everyone will love.
Step 4: Cook potatoes
Introduce the red potatoes to the stockpot and allow them to boil for about 12 minutes. You want them to be mostly tender yet firm enough to hold their shape. Check for doneness by piercing a potato with a fork; it should slide in easily but not break apart. This step lays the foundation for your boil’s incredible flavors.
Step 5: Add seafood and sausage
Next, carefully add the whole shrimp, cleaned mussels, snow crab clusters, and slices of andouille sausage to the stockpot. Cover with a lid and let everything gently boil for about 10 minutes. Watch as the shrimp turn pink and the mussels begin to open, signaling that your seafood is perfectly cooked and ready for the next step.
Step 6: Incorporate corn
After 10 minutes, it’s time to add the sweet corn to your bubbling Cajun seafood boil. Stir gently and boil for an additional 5 minutes. The corn will become tender and sweet, complementing the robust flavors of the seafood and the smoky sausage. This step rounds out your meal beautifully, ensuring every bite is packed with flavor.
Step 7: Make the garlic butter sauce
While the seafood boil is cooking, melt unsalted butter in a small saucepan over medium heat. Add minced garlic and sauté until golden and fragrant, about 2 minutes. Next, whisk in the leftover seasoning mix, lemon juice, and a splash of reserved broth from the boil. This rich and spicy garlic butter sauce will enhance the overall flavor of your homemade Cajun seafood boil.
Step 8: Serve
Ready to feast? Carefully pour the seafood and vegetables onto a newspaper-lined baking sheet for a festive presentation. Drizzle generously with your spicy garlic butter sauce, and garnish with freshly chopped parsley and extra lemon wedges for brightness. Gather around the table and dig in—this homemade Cajun seafood boil is meant to be shared!

Homemade Cajun Seafood Boil Recipe FAQs
What seafood is best for the homemade Cajun seafood boil?
Absolutely! You can use a variety of seafood for your boil, but I recommend opting for larger shrimp, mussels, and snow crab clusters for the best texture and flavor. If you have seafood preferences, feel free to swap in your favorites or whatever is fresh and available!
How should I store leftover seafood boil?
It’s best to store leftover Cajun seafood boil in an airtight container in the fridge, where it will stay fresh for 1-2 days. Make sure to allow the dish to cool completely before sealing it up to avoid condensation, which can make it soggy.
Can I freeze the homemade Cajun seafood boil?
I advise against freezing the complete seafood boil, as it can negatively impact the texture of the shrimp and mussels once thawed. However, you can freeze the spicy garlic butter sauce for up to 3 months, making it easy to whip up another boil in the future!
What should I do if the shrimp overcooks?
Timing is key to perfect seafood. To prevent overcooking, keep an eye on the shrimp as they turn pink and opaque, which usually takes about 10 minutes. If you do find your shrimp overcooked, you can try tossing them in your garlic butter sauce to help mask any dryness.
How can I adjust the spice level in my seafood boil?
Very! To customize the spice level, start with less cayenne pepper and red pepper flakes, tasting along the way. You can always add more if you prefer extra heat… but remember, it’s easier to kick it up than take it down!
Is this seafood boil safe for my pets?
While this dish is tantalizing for humans, it’s not suitable for pets. Ingredients like garlic, onions, and certain seasonings can be harmful to dogs and cats. Always keep your leftover seafood boil out of reach and save it for your family gatherings!
