Traditional Southern Crawfish Boil
jump toRECIPE
This traditional crawfish boil is a classic Southern seafood feast featuring live crawfish cooked with potatoes, corn, onion, citrus, and Cajun seasoning in one large pot. Once cooked, the crawfish and vegetables are typically drained and spread across a newspaper-covered table for a casual, communal meal that’s perfect for gatherings. Crawfish are in season in the spring. If you enjoy seafood boils and crowd-friendly meals, you might also like my classic New England seafood boil or this Louisana-inspired crawfish étouffée.
Why You’ll Love This Recipe
- Perfect for gatherings – A crawfish boil is designed for sharing and makes a fun, interactive meal.
- Bold Cajun flavor – Pre-mixed crawfish boil seasoning infuses the seafood and vegetables with spice and aromatics.
- Simple one-pot cooking – Everything cooks together in a single pot for easy prep and cleanup.
How to Source Crawfish
Crawfish, also called crayfish or crawdads depending on the region, are typically in season during the spring. In Louisiana—the largest producer of crawfish in the United States—wild-caught crawfish season generally runs from mid-January through early July, with the peak harvest occurring between March and May.
If you can’t find live crawfish at your local seafood market, you can often order them online from Louisiana seafood suppliers. Many companies ship live crawfish overnight, making it possible to host a crawfish boil even if you live outside the South. I’ve successfully ordered live crawfish shipped overnight from Louisiana to New Jersey for a crawfish boil at home.
Key Ingredients in This Recipe
- Grapefruit – Grapefruit is added to the boil because the citrus helps to break down the shells of the crawfish and keep the meat tender.
- Corn – I love making the most of sweet summer corn picked up from local farm stands. When buying ears corn, look for a bright green husk that is tight around the corn. Feel the kernels through the husk, they should be plump. (I like to peel back a section of the husk to double check the kernels.) Look at the tassel (the strings at the top), it should be yellow or light brown – it should have a sweet smell.
- Yellow onion – I use yellow onion in this recipe for its mellow flavor when cooked. These onions with a brownish yellow papery skin are a great all-purpose cooking onion.
- Potatoes – I use a mix of both yellow and red potatoes or new potatoes in this recipe. They are small with a thin skin so they don’t require peeling. While I boil them whole they can also be cut in half to cut down on cooking time.
- Seasoning – Rather than making my own seasoning for this recipe I opt to buy a pre-mixed Cajun spice pack. My favorite is from Zatarain’s and can be found at most grocery stores or seafood markets. It’s made with a mix of mustard seed, coriander seed, cayenne pepper, bay leaves, dill seed and allspice. It’s made with salt so no need to include additional.

Pro Tip
Once cooked the crawfish sit for 15 minutes so they absorb the flavor of the spices.
Swaps and Substitutions
- Crawfish: If crawfish are unavailable, shrimp, crab, or lobster can be used in a seafood boil with adjusted cooking times.
- Crawfish boil seasoning: Old Bay or a homemade Cajun seasoning blend can be used instead.
- Corn: Frozen corn on the cob or smaller corn sections can be substituted.
- Potatoes: Red potatoes or fingerling potatoes work well in place of new potatoes.
- Citrus: Adding citrus helps break down the crawfish shells and make the meat tender. Lemons or oranges can replace grapefruit if preferred.
How to Make a Traditional Southern Crawfish Boil (Step-by-Step)
- Prepare the pot and add seasoning. Bring an extra-large pot fitted with a basket strainer and filled about halfway with water to a rolling boil. Add the seasoning mix and stir to combine, return to a rolling boil.
- Add the grapefruit and vegetables. Squeeze the grapefruit halves into the water then add them to the pot along with the potatoes, onion, and corn. Cook for 5 minutes.
- Add the crawfish. Next, gently add the crawfish and cover the pot. Depending on the size of the pot, this may have to be done in batches.
- Cook then remove from heat. Cook for 5 minutes then remove the pot from the heat and let sit for 15 minutes so the crawfish absorb the flavor of the spices.
- Strain and serve. Lift the strainer and pour the cooked crawfish out on a newspaper-lined table outside.
How to Eat Crawfish
- Twist and pull the tail from the head.
- Suck the juices from the head (optional) and discard.
- Next, pinch the tail and bite or pull the meat from the shell.
Traditional Southern Crawfish Boil Additions
- Aromatics like a head of garlic with the top 1/4″ trimmed off can be added for additional flavoring.
- Try adding a smoked sausage like Andouille sausage or Polish Kielbasa to your crawfish boil. Cook for 12 minutes.

- With sauces: Serve with melted butter, hot sauce, or remoulade for dipping.
- For sides: Pair with coleslaw, cornbread, or potato salad.
- With drinks: Lemonade or light beer balances the spicy Cajun seasoning.

- Freezer: Peel leftover crawfish tails and freeze them for up to 3 months for use in other seafood dishes.
- Reheating: Warm gently in a skillet or add the crawfish meat to pasta, soups, or étouffée.

FAQ – Frequently Asked Questions
