Cajun Seafood Boil w/ Garlic Butter Sauce 😋
This easy to make boil is brimming with all the meaty, hearty bites like andouille, shrimp, and crab. And then there’s filling elements like potatoes, corn, and hard-boiled eggs to amp up the fullness of it all. In my honest opinion, a seafood boil is questionable if it doesn’t include big flavor and spices- just keeping it real. You’ll love the heaps of flavor from Cajun seasoning and Old Bay spices all throughout: in the boil itself and in the luscious garlic butter sauce, swoon.

Seafood Boil Recipe Highlights
⇢ First, let’s discuss some main highlights that you’ll appreciate here:
- SOOO EASY, YAY: One of my favorite things about a seafood boil is how effortless they are when it comes to cooking. Plus, there’s also very little hands-on work you’ll have to do here: it’s what I call a low-effort, high reward recipe! Therefore, it makes this Cajun seafood boil clutch for busy weeknights, entertaining, and everything in between. Yes, indeed.
- LIP-SMACKING FLAVA: Over on this corner of the internet, there’s no skimping on flavor. The seafood boil ingredients cook up in a well-seasoned and extra flavorful boil broth. Next, that same boil is smothered in a flavor-filled garlic butter sauce that’ll make you wanna do a little jiggy-jig, ayyeee.
- PERFECT FOR GATHERINGS: The summer is all about having cookouts, hanging with your family + friends, and connection galore. Well, a good ole seafood boil screams community and social gatherings, y’all. This recipe is the quintessential, communal meal to devour with a cozy group! 🫶🏾


What’s The Key To A Good Boil?
Excellent question, let’s talk about. The key to a really phenomenal seafood boil is to make the liquid as flavorful as possible, friends. Without that deep penetrating flavor the ingredients will be bland and sad, oof. Beer is one of the elements that adds a little razzle dazzle to enhance the boil broth. In addition to the beer, plenty of spices and aromatics make the liquid sing in flavorful notes. However, if beer is not your thing, you can surely proceed without it, too.
⇢ I recommend using lagers, IPAs, or pilsners for choices of beer! 👍🏾




Types Of Seafood For Seafood Boil
The types of seafood called for in this recipe will guide you on a really good seafood boil session, but you can also deviate and customize it to your liking! My Cajun seafood boil calls for snow crab clusters and shrimp- more options such as mussels, clams, other crab varieties (king crab legs, Dungeness crab, etc.), crawfish, and lobster tails all work well in seafood boils. Just use about 2 – 2 ½ pounds of your favorite seafood in the boil (make sure the crab you select is pre-cooked!). You can use frozen seafood just fine in this recipe, too.
⇢ It’s important to note that not all seafood cooks at the same rate, let’s look into some cooking time frames for specific seafood:
- Pre-cooked crab: 5-7 minutes (maybe 1-2 minutes longer for bigger pieces).
- Crawfish: about 4-5 minutes for small ones.
- Mussels & clams: about 5 minutes or until the shells open up.
- Lobster tails: about 5-6 minutes for a 5-6 ounce tail (or look for the lobster shell to turn bright red with opaque flesh).

FAQs & Tips + Tricks For Recipe Success
Here’s some extra tidbits & more information about this seafood boil recipe:
- Use an extra large pot: Seafood boils require cooking in a very large pot because once the liquid and food is added, the pot will be very full. I use my largest dutch oven (it’s about 10 quarts). Any super big stock pot or dutch oven is recommended for all the ingredients to fit nicely.
- Beer replacement: Great alternatives to using beer include chicken broth/stock or any nonalcoholic beer as an easy substitute.
- Cajun seasoning: My Creole Cajun seasoning is everything. This well-rounded spice is perfect here because it has a variety of spices all in one. Make my homemade version or use store-bought Cajun seasoning.
- Old Bay seasoning: Seafood and Old Bay are like besties, it just is what it is. This well-known seafood staple is another seasoning blend that contains celery salt, pepper, and paprika to name a few.
- Andouille: This is pre-cooked sausage and comes packed with a touch of heat (it’s smoked, nicely seasoned, and a staple among Cajun cuisine), but you can also use any other smoked sausage that you favor. Kielbasa or beef sausage make great substitutes for andouille.
- Potatoes: Use any small/baby potato variety. Red potatoes are common for seafood boils, but I love baby Yukon gold potatoes for their buttery flesh- either one or a combination of both is nice as well!
- Shrimp: I recommend using colossal shrimp or jumbo shrimp for this Cajun seafood boil. In fact, I typically grab super jumbo tiger shrimp that’s deveined with the peel still on. Peel-and-eat, big shrimp works beautifully here as it delivers meaty, plump bites of shrimp that’s more flavorful.

How To Serve Your Cajun Seafood Boil
Seafood boils are traditionally served by emptying the ingredients onto a newspaper-lined table. Pour the buttery sauce over the goods and then everyone just goes after whatever they desire. It’s quite chaotic and fun in the very best way! Additionally, it makes the clean-up much easier. However, I like to serve it on an extra large baking sheet or platter. Everything is more contained and the garlic butter sauce doesn’t soak into the newspaper.

Summer is here and this Cajun Seafood Boil needs to be enjoyed by you and all of your peeps, everyone’s gonna love! Be sure to tag @butterbeready in your BBR recipe creations, I sure love to see it when you do. Until next time! 🤟🏾

Description
This is the BEST Seafood Boil recipe you can whip up right at home, y’all. It’s loaded with jumbo shrimp, crab, andouille sausage, potatoes, eggs, and corn on the cob that’s simmered in a flavor-filled broth of Cajun spices and aromatics. All that hearty goodness gets drowned and smothered in an epic garlic butter sauce. This finger-licking-good seafood boil recipe is an easy meal that serves a crowd!
Ingredients
For the cajun seafood boil:
- 3 quarts water
- 1 (12-ounce) can of beer- optional but highly recommended
- 3 tablespoons Creole Cajun Seasoning– homemade or store-bought
- 1 tablespoon Old Bay seasoning
- Hot sauce, to taste
- 1 medium yellow onion, roughly sliced into half-moons
- 1 large lemon, cut into wedges- plus more for serving
- 12 ounces andouille sausage, sliced into rounds
- 1 lb baby potatoes, red or gold (or a mix of both)
- 1 lb pre-cooked snow crab leg clusters, fresh or frozen
- 1 – 1 ½ lbs jumbo shrimp, deveined, shell-on or peeled
- 4–6 ears sweet corn on the cob, I use the mini ones
- 4–6 hard boiled eggs- optional
For the garlic butter sauce:
- 1 cup (2 sticks) unsalted butter
- 10 cloves of garlic, finely minced or pressed
- 2 tablespoons lemon juice, freshly squeezed
- 1 tablespoon Old Bay seasoning
- 1 tablespoon fresh chopped parsley
- 1 teaspoon Creole Cajun Seasoning– homemade or store-bought
- 1 teaspoon smoked paprika
- Hot sauce, to taste
Instructions
- Prepare the boil. In an extra large stockpot or dutch oven (about 10 quarts or larger) over medium-high heat, combine the water and beer (if using). Bring the liquid to a boil. Then season the boil with the Creole Cajun seasoning, Old Bay seasoning, and a few dashes of hot sauce- to taste. Add the sliced onion and lemon wedges into the pot. Stir all the ingredients well to thoroughly combine. Let the mixture boil for 15 minutes.
- Add the andouille & potatoes. Carefully add the andouille sausage rounds and baby potatoes into the pot, stirring well to fully combine with the boil. Let the andouille and potatoes cook for 15-20 minutes- or until the potatoes are just about fork-tender.
- Add the seafood & corn. Gently nestle the snow crab clusters into the pot along with the shrimp and corn on the cob. Be sure that everything is fully submerged under the boil and carefully stir to ensure all ingredients are well combined. Continue boiling for another 5-7 minutes, cooking until the shrimp is pink. Meanwhile, prepare the garlic butter sauce.
- Make the garlic butter sauce. On a separate burner, in a small saucepan over medium heat, combine the butter, garlic, lemon juice, Old Bay seasoning, parsley, Creole Cajun seasoning, smoked paprika, and hot sauce- to taste. Stir all ingredients and simmer the sauce until the butter melts and the sauce is well combined, stirring often, about 5-7 minutes. Then remove from heat.
- Assemble cajun seafood boil with sauce. Line an extra large baking sheet with foil/parchment paper (or newspaper if you’d like!). Use a spider strainer to remove the seafood boil contents from the pot and place onto the prepared baking sheet along with the hard boiled eggs (if using)- remove and discard the onion/lemon bits. Note: If you’d like your garlic butter sauce to be thinner, you can add some of the seafood boil broth to adjust to desired consistency. Now, this is the fun part! Pour the garlic butter sauce over the seafood boil ingredients. Then use your hands (fitted with disposable gloves if desired) to toss the sauce with everything, smothering every nook and cranny in sauce.
- Serve seafood boil. Feel free to serve this Cajun seafood boil as-is with everyone just grabbing what they’d like from the baking sheet directly (it’s the chaos and messiness of seafood boils that are so fun!) or divide the boil onto individual plates to serve if you prefer. Serve immediately with lemon wedges, if desired. Be sure to sop up any runaway garlic butter sauce. Enjoy!

Hi Jamie- Lobster tails need about 5-6 minutes to cook in the boil 🙂
Thanks so much for the quick response!
can I triple the recipe and use an 40 quart pan and basket? Could I get away with quadrupling the recipe in a 40 quart? Not sure if the decrease in amount of room with the basket will affect this. Should I keep the onions/lemons outside the basket so I don’t need to pick through those? I am feeding 24 people, but some of them are not big seafood eaters.
Hi there- I’ve developed this recipe as it is written and can only speak to such. However, I’d say use your best judgment from the written recipe as it applies to scaling the recipe and the appropriate cookware. Hope this helps 🙂
Delicious! Just made this with only Shrimp and crab legs for the seafood. Can’t wait to make it again with lobster and clams added!
I made this as is and MAN it’s fantastic, my family loved every bit of it, the garlic sauce is spot on, this is in the rotation.
I’m making this boil this weekend for my sister in law’s birthday. We have 15-18 adults; even when I triple the recipe, 7.5 pounds of seafood doesn’t seem like enough. I know there is sausage and corn and potatoes, but…the birthday girl has suggested ~15 pounds of seafood. Which would mean doubling my already tripled recipe…
Thoughts?
Hi Andrew- I’ve developed this recipe as it is written (serving amount) and can only speak to such. However, I’d say use your best judgment from the written recipe as it applies to scaling the recipe to double/triple the ingredients to feed your desired crowd and the appropriate cookware (multiple pots). Hope this helps 🙂
WOW !!
So I have cooked snow crabs before in just plain water. My question is when making this seafood boil why should the crab legs be pre-cooked?Sorry may be a dumb question just want to make sure I do this correctly. Thanks!
Hi Lisa- Feel free to use cooked snow crabs for the recipe, no worries. Since they’re already cooked, the overall boil time will be just a few minutes for them to absorb the boil seasonings 🙂
My 14yo stepson has been keen for a seafood boil for about a year now, but we live in rural Australia, so I could only find fresh prawns (shrimp) and substituted chorizo instead of Andouille sausages, but I followed your recipe for everything else and … SUCCESS! Thank you ☺️
Good to know, as I am using chorizo in a pinch tonight! And since I could not get crab legs today, I have scallops to add with the shrimp. Fingers crossed 🤞
Love love
This was my first attempt at a seafood boil and it was fantastic! My kids asked if they could have it again for dinner soon. This will be my go-to recipe. Thanks for sharing!
Hi! I think i can make the Cajun seasoning from scratch, but I cannot find Old Bay Seasoning in Norway 🙁 What is the best substitute for this, please?
Hi there- You can simply just double up with Cajun seasoning if you don’t have access to Old Bay 🙂
Hey, thank you for replying promptly 🙂 I found a simple substitute recipe for Old Bay and this combined with your Cajun recipe and procedure, just adding a sprinkle of sugar, was a hit at home!!! It made my and my partner’s birthday today special. He was all praises to this. Thank you!!! Just an idea for others, I had mussels, prawns and crayfish only and it was still tasty.
Hi,
What kind of hot sauce and beer do you use for your recipe? 🙂
Hi there- I use Louisiana hot sauce or Crystal…& any IPA will be nice! 🙂
I love, love, LOVE this recipe! Always get rave reviews, so thank you so much for sharing!
The thing I miss most about the South, is the food and I appreciate you helping me to bring those memories home.
I am planning to make this recipe when my brother and his wife come to visit. I plan to use the crab and shrimp but also want to add clams and 2 whole lobsters. Should I double the water, beer and seasoning? When should I add the clams and whole lobsters?
Hi there- You would add your seafood of choice as written in the recipe instructions- making sure to use enough water/beer to cover and season the water to preference. I also encourage you to read the blog post in its entirety as I provide notes for alternative seafood 🙂
How long do I cook the Crab if my grocery store does not have any Pre-Cooked?
Anywhere from 5-10 minutes 🙂
My 16 year old wanted a seafood boil for his birthday dinner, this was my first time making one. I tripled the recipe and it turned out perfect! This was a huge hit with my family and the garlic butter sauce was delicious! My 8 year old is already requesting this for his birthday dinner this winter.
Fantastic Recipe, my husband was a huge fan! Delicious!
Made it with mussels, shrimp and scallops. The scallops were in for just over two minutes and came out tender. The first seafood boil I have ever made. Easy to follow up recipe and very tasty, especially the butter sauce. Highly recommend you give it a try!
This recipe is absolutely amazing! Truly restaurant worthy. I’ve made this twice now and it was perfect both times. I usually don’t give reviews for recipes but this one deserved it. It’s my new go to for any seafood boil.
Very good recipe I will say, was my first boil! I bought a turkey fryer with strainer. It did perfect, turned out awesome for my first boil! Thanks for the recipe, I’ll definitely use it again!
I have made this dish at least three times and it never disappoints! The garlic butter sauce should be outlawed, it’s so good!! Thank you for sharing!
are the eggs boiled or put in sauce to boil
Hi there- I recommend boiling your eggs separately from the boil or grab some pre-boiled eggs and incorporate them prior to serving the boil ingredients (when your ready to cover everything with the sauce).
Can I use non alcoholic beer? I have samuel adam’s IPA on hand
Hey Camille- Yes, you can use non-alc beer! 🙂
What hot sauce do you like to use?
Hi there- Louisiana or Crystal hot sauce 🙂
Came out great
