This is best seafood boil recipe! Not only does it have a variety of seafood with the best flavors but it's the ultimate complete meal that the entire family will love! Seafood boils are the perfect outdoor meal to entertain with especially when made with plenty of love, one of the best garlic butter seafood boil sauces, and a dash of hot sauce.

Now that summer is in full swing and fourth of July is just around the corner, I'm gathering all of my favorite seafood and making this cajun boil. Nothing says 'summer' to me like burying my bare hands into a classic cajun seafood boil and lathering every piece in garlic butter.

This cajun seafood boil recipe is also great way to celebrate the holidays and so much fun to indulge in a New Orleans style Louisiana Crab Boil approach to family gatherings!

Different from crawfish boils, we're using creole seasoning with beer to make a seasoned broth along with lemon halves, garlic, and yellow onion in the pot for great flavor. We're also throwing in some fresh corn, smoky sausage, fresh shellfish. Mix a few pounds of seafood and traditional ingredients together and you have a fantastic seafood boil full of cajun flavors.

Don't forget the delicious cajun sauce! It's an easy yet amazing garlic butter seafood boil sauce that you need to drown absolutely everything in.

Ingredients for Cajun Seafood Boil

For the Seasoned Broth

  • Beer: This may come as a surprise but beer actually enhances the flavor of the broth. Use your favorite kind.
  • Water: To mix with the other liquids.
  • Bay leaves: they add subtle herby and peppery flavors.
  • Seafood boil seasoning: I used a combination of Old Bay, smoked paprika, Cayenne pepper, black pepper, salt, and dried thyme.
  • Lemons
  • Garlic and Onions: This recipe calls for lots of fresh garlic so make sure you have plenty! I like using a lot because the garlic and onion make such a flavorful broth. If you don't feel like chopping up a bunch of garlic, use garlic powder instead.

Seafood Boil Ingredients

  • Red potatoes: If you don't have access to red potatoes, Yukon potatoes, baby potatoes, or small new potatoes work too.
  • Andouille sausage: Andouille is a slightly spicy sausage. In my opinion, it's the best sausage for a seafood boil but if you prefer something milder, use kielbasa.
  • Sweet Corn: Use whatever variety of corn you'd like as long as it's fresh. Cutting the corn into thirds for roughly 2-inch pieces will ensure they cook faster.
  • Jumbo shrimp: Use the biggest shrimp you can find. Now is not the time to skimp! Colossal shrimp or jumbo shrimp are the best. Also, you can use peeled or shell-on shrimp, depending on your preference. (the bigger the shrimp the better for this seafood boil recipe) Get them deveined to cut down on prep time.
  • Snow Crab clusters: these are the bodies broken into pieces with legs attached, but you can just find the snow crab legs on their own at your local fish monger! If you can't find snow crab, try king crab legs or even dungeness crab legs! Make sure that they're pre-cooked!
  • Lobster tails: you'll want to Maine Lobsters or North Atlantic Lobsters, also known as cold water lobsters. They have the best flavor and don't taste fishy like other breeds.
  • Mussels: this is optional. I like using pre-cooked mussels, they don't need to boil as long as raw mussels.
  • Clams: Before serving, discard any clams that didn't open up.

Garlic Butter Sauce

ingredients for  garlic butter seafood boil sauce - butter, garlic, onion, lemon, seasonings, parsley, and broth.

As the seafood cooks, make this rich and buttery sauce that perfectly complements the fresh seafood. It's so delicious when poured on top of this seafood boil.

  • Butter: The base of this sauce. You can use salted or unsalted.
  • Garlic cloves: I told you we'd be using a lot!
  • Cajun seasoning: Be generous with this essential seasoning!
  • Old bay seasoning: This is added for flavor and color.
  • Sugar: The hint of sweetness will balance out the other flavors.
  • Salt: Just enough to taste.
  • Reserved broth: If you want a thicker sauce, use less of this. If you want a thinner sauce, use a bit more.
  • Fresh parsley
  • Red pepper flakes - this is optional. Use if want an extra kick of spice!

Tips for making a Seafood Boil

  • Don't overcook the shrimp! You'll know when the shrimp is finished when it turns pink and curls a bit. If it appears your shrimp is cooking faster than everything else, take them out of the pot.
  • Customize this recipe to your liking! If you have different seafood that you'd like to add, throw it in the pot for the seafood boil. Just be mindful of cooking times so that you don't overcook any of the ingredients.
  • Pro tip: Try to use as many fresh ingredients as possible! Fresh ingredients are key to a delicious seafood boil.
  • I would not recommend making this dish ahead of time, it tastes best right out of the pot.
  • Use the biggest shrimp you can find. Now is not the time to skimp! You can use peeled or shell-on shrimp, depending on your preference. (the bigger the shrimp the better for this seafood boil recipe)
  • If you can't find cajun seasoning, a great option is this  homemade cajun seasoning recipe.
  • If using frozen shrimp, thaw the shrimp for about 15-20 minutes in cold water prior to throwing in the boiling water.
  • Be sure to discard any clams that didn't open up. They're a pain to find in the seafood boil!

Seafood Cooking Times

It's easy to do - don't overcook your seafood! Here's a quick guide to cooking times:

  • Pre-Cooked Frozen Crab Legs: 5-7 minutes (about 15-20 minutes for raw crab)
  • Shrimp: 3-5 minutes (remove when they resemble the letter "c" and turn pink. If they're tightly curled, they're overcooked)
  • Lobster Tails: 4-6 minutes, when the shells turn bright red and the flesh is white and opaque
  • Clams and Mussels: 5 minutes, or when the shells pop open

Pro tip: The seafood used in this recipe cook at different times. Put the longest cooking items in the boil first! The order is crab legs - lobster tails - clams and mussels (if using) - then shrimp!

How do you cook a Seafood Boil?

After reading the list of ingredients, you'd think the cooking process would take forever. However, you really just throw everything into a pot, little by little.

An hour later, the seafood boil will be finished and you'll have a heap of all types of seafood sprawled on a table in front of you. (If you're a visual person, check out the video below!)

Make the Broth

  • Firstly, add beer, and water to a large stockpot. Over high heat, bring everything to a rolling boil and then add bay leaves, Old Bay seasoning, smoked paprika, cayenne pepper, black pepper, thyme, salt, lemons, garlic, and onions.
  • Stir together and boil for 5 minutes in order to allow flavors to come together.

Add Potatoes, Sausage, and Seafood

  • Add halved red potatoes and corn to the pot and allow them to cook until the potatoes are tender but not mushy (about 15 minutes). Then add sausages and allow them to cook for another 5 minutes. (Image 1)
  • Add crab legs, lobster tails, mussels, clams, and shrimp. Cover the pot with a lid and allow everything to boil together for 5-7 minutes. (The mussels and clams will pop open once they are finished and the shrimp will be pink) Stir together, save 2 cups of the broth, then drain. (Image 2)

Roll out newspaper or a large serving tray and finally, place the seafood on top. Garnish with fresh parsley and lemon wedges.

Prepare the Garlic Butter Sauce

  • Melt butter over medium-low heat, then add garlic and cook until fragrant, about 3 minutes. Then add cajun seasoning, old bay seasoning, onion powder, sugar, and salt to the melted butter. (Image 3)
  • Add 1 cup of the reserved broth and simmer on low for 3-5 minutes, until sauce thickens. If using, stir in red pepper flakes and remove from the heat. (If you want a thinner sauce, then add 2 cups instead.) Add a little bit of lemon juice and hot sauce if you like a little heat! Pour over the seafood and reserve the rest for dipping. (It's SO good)

What goes with Cajun Seafood Boil?

You can definitely enjoy this seafood dish without any additions but it's also a great dish with these sides:

For drinks, I love a nice crisp cold glass of white wine or making a large batch of my white wine sangria. You can also make it a party and try these:

Storing Leftovers

Some say that this seafood boil is even better the next day! Store any leftovers in an airtight container for up to 3 days but avoid the microwave. When you are ready to reheat, simply add some water to a pot with the leftover seafood boil.

Cook it over low heat until it is evenly warmed.

The garlic butter sauce can be stored and frozen for up to 2 months. Simply scoop and microwave when you want to use it.

  1. Exceptional recipe! I had friends over and made this over the weekend and have to come back and comment to let you know how delicious this is. It's exactly the taste I want from a restaurant but made at home. I can't wait to make this recipe again!

    • If you sear the sausage and corn there's no need to add them to the boil since they'll be cooked. It technically would add to cook time since you'd be cooking them separately but it shouldn't be too much longer.

  2. 5 stars
    This came out so good! That broth was very flavorful and the seafood was seasoned so well. We also loved the sauce!

  3. 5 stars
    I made this over the weekend and had some neighbors over. It was a FLAVOR FILLED FEAST! I added more water to the pot, but everything came out perfect. Everyone especially loved that sauce. Wow, just so delicious. Also very easy to make. I may make this again for Christmas, so glad I tried this recipe!

  4. 5 stars
    Seafood boil was incredible. Everything from the tender shrimp to the broth and the sauce were delicious. The sauce especially had so much flavor and I loved that I could add more seafood and still had enough broth. I added more lobster and crab legs and everything came out perfect. Will definitely make this again.
