    • Fresh shrimp - Raw jumbo shrimp that have been deveined with the shell still on.
    • Crab leg clusters - We used snow crab legs, but King crab legs also work.
    • Lobster tails - Thawed, and cut in half lengthwise.
    • Mussels - We chose mussels that were already fully cooked, and then just add them in the last few minutes of cooking.
    • Kielbasa or andouille sausage - A nice smoky sausage compliments the meal really well, and also adds more protein.
    • Fresh corn & red potatoes - Cut in half widthwise.
    • Lemons - We use lemon halves in the boiling liquid, but also lemon juice and lemon zest in the dipping sauce. As well as lemon wedges for serving.

    • Water
    • Onions
    • Garlic
    • Unsalted butter
    • Seasonings - We use a mixture of kosher salt, black pepper, red pepper flakes, smoked paprika, cayenne pepper, cajun seasoning, Old Bay seasoning, onion powder, garlic powder, and dried thyme in the seafood boil seasoning. We use pretty much the same seasoning blend for the dipping sauce.
    • Bay leaves
    • Fresh parsley - For the dipping sauce and to garnish.

    Visit the recipe card for the full quantities and nutritional information.

    ✨Substitutions & variations

    Here are a few suggestions on additional flavors to try, or simple variations to this recipe.

    • Less or spicy - Omit some of the cayenne pepper, cajun seasoning, and red pepper flakes for less spicy, and add more if you like it hotter!
    • Swap the potatoes - Small new potatoes also work well in place of red potatoes.
    • Swap beer for white wine - This will also complement the flavors of the seafood very well.
    • Use spicy Italian sausage - If you like, you can add whole links of spicy Italian sausage to the pot, then cut them up after everything is completely cooked through.
    • Lemony - Lemon and seafood just go together really well, if you love lemon, feel free to add more lemon juice and zest to the dipping sauce.

    🔪Prep work

    • Wash and prep all seafood. Cut the lobster tails in half lengthwise, devein shrimp if necessary, and scrub mussels.
    • Halve potatoes, corn on the cob, and a couple of lemons.
    • Peel and smash 12 garlic cloves, and mince 8 garlic cloves for the butter sauce and set aside.
    • Chop parsley.
    • Cut sausage into roughly 2-inch pieces.
    • Measure out all remaining ingredients.

    ✨Tips & tricks

    • Season to taste. This recipe is right on the edge of spicy. It's very well seasoned, with a little heat, but we didn't go overboard. It may seem like a lot of seasoning in the seafood boil liquid, but it helps to infuse the potatoes and other than that, doesn't impact the final heat level much. With that being said, when making the garlic butter sauce, taste as you go. If you find the mixture to be too spicy, add more melted butter!
    • Don't overcook the seafood. Cook times and reheating times of shellfish vary, to ensure nothing gets rubbery and overcooked, make sure to add different seafood items in stages. As soon as the seafood is done, remove it from the pot, while the other seafood cooks. Check out our guide below on how to know how long to cook each item in this recipe.
    • Keep the raw seafood cold before cooking it. Seafood and shellfish can spoil quickly in a hot kitchen, and no one wants to be sick from bad shellfish! Keep all items refrigerated or on ice after prepping them until it's time to cook.
    • Consider wearing gloves and bibs. This a pro tip to keep you from getting your hands and clothes dirty! This recipe is a bit messy to enjoy.

    💭Frequently Asked Questions

    How to store reheat the seafood the next day?

    Store any leftovers on a baking sheet tightly wrapped with foil or plastic wrap, or an airtight container in the fridge for 1-2 days. To reheat, add to a 350°F oven, and cook for 15-20 minutes.

    You can also reheat the leftovers by steaming them on the stovetop in a large stockpot with a lid, or in a cast iron skillet with a little water.

    Do not freeze leftovers.

    How to make sure the seafood is cooked through.


    Different seafood will cook at different times. We take seafood out as it finishes cooking, to ensure we don't overcook anything.

    Snow crab: Boil for about 5 minutes, just to reheat. Most crab is already cooked when you buy it, so you're just reheating it!

    Mussels: If mussels are fully cooked (like ours were) just boil until they open up completely. This should only take about 3-5 minutes. If a shell doesn't open, discard it, as it means the mussels have gone bad.

    Lobster: Boil for roughly 4-5 minutes, until the shell is bright red and the meat is no longer translucent.

    Shrimp: Boil for 2-3 minutes, until the shrimp is no longer translucent.

    How to crack crab legs without tools:


    Believe it or not, there are no special tools needed to crack crab legs, and you can simply use your hands by cracking the legs at the joints and pulling out the tendons.

    Then, you can run your fork inside the shell to break it open or use your hands to crack the shell in half. Make sure to wrap the crab legs with a towel or wear gloves so you don't hurt yourself.

    How many pounds of seafood do I need per person?


    You should plan for about 1-1.5 pounds of seafood per adult, and about ½ pound per child. Don't forget to add plenty of potatoes, sausage, and corn as an easy way to fill everyone up.
