Fill a large pot with water. Bring the water to a boil. Add the Louisiana Crawfish Shrimp and Crab Boil, Cajun seasoning and Lemon Pepper seasoning. Stir well to a rolling boil.
Add the garlic, corn, potatoes, sausage and lemon slices. Cover the pot with its lid and cook for 10 minutes.
Taste the crawfish boil water. If it’s too salty, add more water. If it’s too bland, add more seasonings to taste. Transfer the crawfish into the pot and cook for 3-4 minutes, with the lid covered.
Turn off the heat and let the crawfish soak for 10 minutes. The longer the crawfish soaks, the spicier they will be. Remove all the ingredients using a strainer and serve immediately. Discard the crawfish boil water.
