Authentic Louisiana Crawfish Boil

Learn how to throw an authentic Louisiana Crawfish Boil! We like our spicy crawfish with small red potatoes, corn, onion and lemons!

I think that having an annual tradition or event outside of the normal holidays is so important. There's less pressure, less travel and no gift buying. It's all about fun!

For the past 6 years, my husband and I have been throwing a crawfish boil for about 20 of our closest friends and family. It's the closest thing to Mardi Gras and Cajun cuisine that we can get here in the Midwest!

This all started as a celebration for my husband's 25th birthday party. His good friend Brian and I pulled off a surprise party for him, having live crawfish flown in from Louisiana Crawfish Company. The idea came from the time my husband and his friends spent 10 days in New Orleans right after Hurricane Katrina, helping with cleanup efforts.

During that time in Louisiana, they fell in love with the local cuisine, and became crawfish and shrimp boil fanatics. The crowd at our crawfish boil has changed a bit each year, and now we adults are almost outnumbered by kiddos! It's so much fun that one of our friends has declared it his "second most favorite holiday each year," just barely surpassing Thanksgiving.

How to Order Live Crawfish + How Much Crawfish Do I Need Per Person?

We live in Missouri, right smack dab in the middle of the country. While I suppose it's possible for us to drive down to Louisiana to get live crawfish, it'd be quite the trip!

Lucky for us, we found a company (Louisiana Crawfish Co.) that ships fresh crawfish overnight. 

 I think crawfish eaters fall into three categories: 1) fanatics, 2) nibblers and 3) non-eaters. We only purchase crawfish for the fanatics, because we've learned that nibblers typically only eat one or two crawfish, just for the experience.

Our first year, we ordered WAY too much. Now, for our our boils, I typically order 5 pounds per fanatical eater, and don't count the "nibblers" at all. But I know our crowd super well at this point and we have our order dialed in.

If you don't know who will eat crawfish, I recommend going with the standard recommendation of 3 pounds of crawfish per person for your entire group.

I know this sounds like a lot, but remember that crawfish are just little crustaceans, a lot of the weight is in the shell. The meat is a small treasure you have to work to get to!

How to Prepare the Crawfish for Boiling

We always place our orders for a Saturday morning arrival. This typically means the crawfish are harvested, packed and shipped overnight sometime on Friday.

The crawfish will arrive in a net bag. A soon as you receive it, rinse it with fresh water. This is the best way to remove dirt and debris upfront.

Then, we let crawfish hang out in a cooler with just a bit of loose, fresh ice. You may need to drain the cooler as the ice melts. Crawfish like a bit of water, but they also need access to fresh air. They can drown if they are submerged too long!

Right before you cook the crawfish, you'll need to purge them. It's hard to put this delicately but doing a saltwater purge will help them get rid of any... "impurities" before you cook them. Think of the dark vein on shrimp. Yep, crawfish have those too! Purging the crawfish them will clear that vein out.

To purge the crawfish, use a large ice chest or a large beverage tub. Place the crawfish in the chest, then fill it with water, just to the top of the crawfish. Sprinkle salt over the top (exactly amounts in recipe below), stir gently, then allow to soak in the salt water for about 5 minutes.

Drain and rinse the crawfish, then repeat the process a second time before cooking starts. Dead crawfish will float to the top, pluck and remove those dead mudbugs as they show up!

How to Prepare your Crawfish Boil Liquid

About 20 minutes before you're ready to start boiling the crawfish, light up your propane cooker. Add water to your big pot. We have a 30-quart stainless steel pot, but they also make them in larger or smaller sizes.

You can work with most any pot size, really, just know you may have to do extra (or less) batches!

For our size boiling pot, we typically fill it with between 6-7 gallons of water.

Just before adding crawfish, add crawfish boil spices, lemons and onions to start working flavor into the boiling water. I use this Crawfish Boil Seasoning, but there are plenty of options out there for you to use online and in grocery stores!

How to Boil Crawfish 

When your water is seasoned and ready, add the live crawfish to the steamer basket and dunk it into the seasoned water. Allow the water to come back to a boil for about 2 minutes, then turn the burner off. Place the lid on the pot and allow the crawfish to simmer in the seasoned water for about 20 minutes.

After 20 minutes, drain the crawfish and place them in a clean cooler to steam, sprinkling additional cajun seasoning over the top of the crawfish. The crawfish should steam in the cooler for another 20 minutes before being served. While they steam, it's a great time to cook your corn and potatoes in the hot seasoned water. 

To serve, dump steamed crawfish on table lined with plastic tablecloth. Eat!

What sides go well with Crawfish Boil?

In my opinion, the perfect sides for a crawfish boil are those that can be thrown right in the pot!

After your crawfish has been boiled, you have some tasty, well-seasoned water that can be used to cook any variety of vegetables.

We typically buy corn on the cob and b-sized (small) red potatoes. I love these two sides because you can cook them right in the liquid boil for the crawfish!

You can also cook these items alongside the crawfish, but be cognizant of cook time because they do not need a full 20 minutes of boiling like the crawfish.

Side Dish Cook Times: Fresh corn boils in 2-3 minutes, frozen corn boils in 6-8 minutes and b-size potatoes (about 1-5 to 2 inches round) boil in about 15 minutes.

In addition to these easy boiled sides, I usually ask everyone to bring an appetizer or dessert to share.

Serving and Eating the Crawfish

Sometimes cleaning up after larger parties can be a drag! Not so with a crawfish boil. Cover a table or two with vinyl or disposable plastic tablecloths.

If it's windy, you may need to tape the tablecloths down. If you forget tape like we did this year, just find something heavy to anchor the tablecloths down, like a six pack of beer!

Dump the drained and steamed crawfish and any boiled sides directly on to the tablecloth, and let your guests gather around to pick.

It's a good idea to have a few seasoned pros help the newbies learn how to pick the meat out of the crawfish. If you need help learn how to eat crawfish, watch this video.

Keep several rolls of paper towels around the table to allow your guests to wipe their hands frequently, and a trash can on both ends of each table to throw discards.

When you're all out of crawdaddies, simply gather up your plastic tablecloth and pitch it in the trash can! Clean up does not get any easier than that!

Please note that Louisiana Crawfish provided our live crawfish for this year's boil, and we have used them to ship our crawfish independently in previous years. I was not otherwise compensated for this post, and all opinions are mine alone, as always.

I'm from Louisiana and crawfish boils are a lot of fun! Great time for family and friends! But one thing you might want to do before you boil is purge your crawfish in salt water using non iodized salt......the purging will clean the crawfish on the inside :) ....also if you use a stick of real butter in the pot makes them tasty and easier to peel.....

Laissez les bons temps rouler!!!!!

We'll have to try the salt tip! We typically follow the instructions from the crawfish company, no complaints! Love the idea of adding butter, that can only make it better.

Oh girl! You gotta purge those crawfish in salt water to get em clean. Otherwise you're just eating mudbugs!

Hi there! Thanks for the tip! We've always followed the instructions provided by the company and purged them in running tap water, have been doing this for over 5 years and no noticeable taste difference from what we've had down in LA! We'll give it a try next year.

I regret not taking advantage of the crawfish boils when I lived in Houston.

This looks like so much fun! I've had crawfish in things before, but never had the opportunity to just eat one out of the shell. (Yankee to the core)

I hear you! I'm not sure I would have ever tried them had Craig not come back from NOLA all starry eyed about them! ;)
