Crawfish Fettuccine

I have lived in this close-knit community all my life and enjoy cooking Cajun dishes, especially those with seafood. Along with a green salad and garlic bread, this dish is great for family gatherings. The recipe can easily be doubled to serve a larger group, and if you’d like it less spicy, remove the seeds from the jalapeno before chopping it. —Carolyn Lejeune, Welsh, Louisiana

    I've made this dish several times over the years and it is very tasty. I use shrimp instead of crawfish. I also use Pepper Jack cheese instead of Velveeta (because I have an allergy to Annatto, the dye used in Velveeta). An excellent casserole!

    Good, but needed some acid to cut the creaminess.

    This is so good! Crawfish can get expensive so sometimes i use shrimp or i combine crawfish and shrimp. I've made this recipe several times and the only thing i change is i only use about 1 cup of butter.

    We made this for a bikers pot luck and I received great reviews. Crawfish were hard to find so we used langoustine lobster tails and it was great!

    This recipe was delicious! I thought the butter was alot but the sauce ended up so thick and creamy and not overly cheesy that we though it could be served with crackers as a dip!
