Ingredients

  • 30 lbs live crawfish
  • water
  • 4.5 lb crawfish and crab boil seasoning
  • 2 lb lemons halved
  • 4 sweet onions quartered
  • 2 bulbs garlic
  • 5 lb red potatoes
  • 4 lb smoked sausage sliced into 2-inch pieces
  • 12 ears corn halved
  • 20 oz Brussels sprouts trimmed

Cajun crawfish dipping sauce

  • 1 cup mayonnaise
  • 1 cup ketchup
  • 2 lemons juice only
  • 3 tbsp Cajun seasoning
  • 1 tbsp prepared horseradish
  • 1 tbsp garlic powder

Instructions

To clean the crawfish

  • Place live crawfish in a large bucket or cooler and cover with water.
  • Stir gently and remove any dead crawfish that float to the top—they should be discarded.
  • Drain and repeat the process at least three times or until the water runs clear.

Prepare the boil water

  • Fill a large stockpot halfway with water and set it on a propane burner.
  • Add the Crawfish & Crab Boil seasoning and turn the heat on high.
  • Squeeze the juice from the lemons into the water, then toss in the lemon halves.
  • Add onions, garlic, and potatoes, then bring the water to a boil for 15-20 minutes until potatoes start to soften.

Cook the crawfish

  • Add the sausage and crawfish, cover the pot, and boil for 5 minutes.
  • Turn off the heat.
  • Add the corn and Brussels sprouts, then cover the pot again. Let everything soak for 30-45 minutes, allowing the crawfish to absorb all the seasoning.

Serve

  • Once soaked, remove the basket from the pot and dump the crawfish onto a newspaper-covered table for serving.
  • Alternatively, transfer the crawfish to a dry cooler to keep them warm until ready to serve.

Cajun crawfish dipping sauce

  • In a small bowl, mix together mayonnaise, ketchup, lemon juice, Cajun seasoning, horseradish, and garlic powder until smooth.
  • Serve alongside the crawfish for dipping.

Notes

What ingredients are in Louisiana seasoning?

I used a spice blend from Louisiana Fish Fry, which includes a blend of traditional ingredients like garlic, onion, paprika, and lemon. 
If you want to try making your own, you can go with:
  • ½ cup kosher salt
  • ¼ cup paprika
  • 2 tbsp cayenne pepper (adjust for spice preference)
  • 2 tbsp black pepper
  • 1 tbsp white pepper
  • 1 tbsp garlic powder
  • 1 tbsp onion powder
  • 1 tbsp dried thyme
  • 1 tbsp dried oregano
  • 1 tbsp celery seed
  • 2 tsp mustard seeds (or 1 tsp ground mustard)
  • 2 tsp bay leaves, crushed
  • 1 tsp crushed red pepper flakes (optional, for extra heat)
  • 1 tsp ground cloves or allspice (optional, for depth)
