Crawfish and Cauliflower Soup

Crawfish Cauliflower Soup in a bowl with fresh bread.

I love cooking with crawfish. Since I live no where near Louisiana, frozen crawfish are usually the only crawfish I have access to.

But last week, we scored LOTS of fresh crawfish. My husband organizes an annual crawfish boil for Charlotte, NC area Tulane Alumni at a local park. The University arranges to have live crawfish flown in from Louisiana (how’s that for a cool Alma Mater?). Well this year they sent too many. Way too many. We came home with a whole 35 pound sack and it allowed me to try a bunch of new crawfish recipes.

This one for Crawfish Cauliflower Soup is an adaptation of a recipe published in Louisiana Cookin’. BTW, if you like cooking magazines, this is an excellent magazine with lots of great recipes, many of them seafood, as well as articles on Louisiana restaurants and festivals.

This soup is rich and creamy, with just the right amount of spice from a combination of red and white pepper. The recipe is meant to utilize leftovers from a crawfish boil, but if you’re not planning a crawfish boil, you can still make the recipe by using 1 pound of frozen crawfish tail meat. I’d add a fair amount of cajun seasoning to the crawfish when sauteeing in butter since crawfish from a boil tend to be fairly spicy. Throw some uncooked red potatoes cut into 1-inch pieces in with the cauliflower so it has time to cook and add kernels cut from an ear of corn about 10 minutes later.


You’ll want some nice, fresh bread to dip in the soup. It’s comfort food Cajun Style.
