Instructions

Preparation

First thing to start the crawfish boil recipe, grab yourself a large cooler or a large ice chest and fill it with fresh water. Toss in your pound sack of crawfish and purge them for 20–30 minutes. Drain the crawfish, refill, and purge again until the water runs clear and you don’t see any dirty water.

While they soak, sort through and drain crawfish that didn’t make it. Any dead crawfish should be tossed if it ain’t moving, don’t risk it. They can make you sick and they’re easy to spot after cooking (the end of the tail stays straight).

Halve your lemons, peel the garlic, rinse your mushrooms. Cut the sausage into chunks- this is your sausage drop later in the cook. Get your corn, shrimp, and all your gear portioned and ready.

Cooking

Fill your large pot halfway with gallons of water- roughly 35–40 quarts. Bring it to a rolling boil over high heat. This’ll take 30–45 minutes depending on your burner. Once boiling, pour in your crawfish boil seasoning- dry crab boil, liquid boil, bay leaves, whatever mix you love.

Let the seasoning packet infuse into the pot of water to your taste for 10 minutes for that bold, southern states-style heat. Now start layering in the ingredients / vegetables for this crawfish boil recipe:

  • Add red potatoes and halved lemons and boil for 5 minutes
  • Add garlic and boil for 10 minutes
  • Drop in andouille, smoked or Italian sausage and boil for 5 minutes
  • Add mushrooms and boil for 5 minutes
  • Toss in frozen corn and boil for 5 minutes
  • Carefully add your fresh crawfish and bring it back to a boil- cook for 3–5 minutes max
  • Kill the heat and immediately drop in frozen shrimp
  • Let everything soak in the seasoned broth for 30–40 minutes

This is the crawfish soak where all the magic happens. As the pot of water cools, the flavors pull deep into the little crustaceans and shrimp. It’s how you go from a good shrimp boil to a great seafood boil.

Serving Suggestions

When the soaking process is done, grab your large bowl or head straight to the picnic table. We like to line the table with newspaper or butcher paper and just dump it all out. Make sure to have plenty of paper towels on hand this is messy business in the best way.

Set out bowls of melted butter, Cajun seasoning, and your favorite hot sauce. I also like throwing in some green beans or extra lemons for that bonus bite. For drinks? Ice-cold beer or sweet tea fits the vibe perfectly.

Recipe Notes & Pro Tips

Don’t skip the purge – it removes the grit and helps you spot any dead crawfish. You can use any combo of crab boil seasoning, old bay, or liquid boil depending on your spice tolerance. Don’t overcook the crawfish. If they float fast and the tails curl, they’re done right. If they’re straight, they were dead crawfish and should be tossed.

You can absolutely swap out the sausage for other proteins too. Just make sure it’s a sturdy link like andouille sausage that can stand up to a full boil. And if you’ve got leftovers (unlikely), they reheat great in a skillet or added into pasta.

Variations + Other Tips

There are different ways to make a good crawfish boil – this is just how we do it here. Some folks add oranges, seasoning mixes, or throw in extras like artichokes and Brussels sprouts. The beauty of a crawfish boil recipe is that you can riff on it and still get much flavor.

It’s best done in the spring during crawfish season, but some parts of the United States can get fresh live crawfish at other times. Look for them in grocery stores with seafood counters, or buy in bulk and ship overnight.

Storing Crawfish Before Cooking:

Just keep them cool, moist, and cook them same day if possible. If you need to store them overnight in a cooler with a bag of ice. Make sure the drain plug is open so the water can run out and they don’t drown. I like to keep a damp towel of them (keep them in the sack) so that the ice doesn’t kill them either. Make sure you keep the top of the cooler cracked to enable airflow so they don’t suffocate also.

The best time to eat crawfish? When you’ve got the whole crew together outside, music going, and a pot of water steaming away. A large container for discards, a large cooler for drinks, and some folding chairs – and that’s all you need.


Once you try this best crawfish boil recipe, you’ll want to run it back next time with an even bigger crowd.
