Do your usual crab boil. I start with potatoes first, remove them when tender, add corn, sausage crablegs in pot together bring back to a boil for about 10 mins. Turn off flame & add shrimp, after 10 min. remove everything from pot. For garlic butter, just sauté butter in minced garlic, oregano, basil. Pour over boil and sprinkle with cajun seasoning, paprika, & parley flakes.
Crawfish bisque. Pour 2 cans cream of potato soup, 1 can cream of mushroom soup, 1 can whole kernel corn (undrained), one stick of butter cut into pieces, 4 oz cream cheese, 1 pint half&half, 1 pkg frozen crawfish meat - thawed, 1/4 tsp cayenne pepper into crock pot and simmer for ~3 hours. This is my family's Christmas Eve dinner! So easy and so good.
