Creamy Crawfish Fettuccine is spicy and cheesy with plenty of crawfish tails. It’s probably my favorite way to eat crawfish. Crawfish Etouffee Balls are a close second.

You’ll need a pound of frozen crawfish tail meat for this recipe. It can be hard to find in some areas, but quite a few specialty grocery stores carry it.
No crawfish? You could easily substitute shrimp in this recipe.
Rich, Creamy, Cheesy Texture
Velveeta cheese makes this Crawfish Fettuccine super creamy and cheesy. I know some people balk at using Velveeta, but it really works in this recipe.
Sour cream and half-and-half add even more richness. This is a truly indulgent pasta dish. The kind you make only for special occasions. Like Mardi Gras. Double the recipe and make a huge batch for a Mardi Gras party.
How To Make Spicy
To add a little spice, I use Cajun or Creole seasoning. Tony Chachere’s is my favorite. The seasoning just adds a little heat. If you want more, add 1/4 to 1/2 teapsoon of cayenne pepper and/or serve with TABASCO Sauce.

This is my second time making this crawfish fettuccine each time it was it’s been good it comes together good and my family love it even though I don’t tell him it’s crawfish.
I’ll make it again but I still have to tell them is seafood fettuccine.
Excellent!!! Super easy and delicious. I added a little onion powder, garlic powder and 2 lbs crawfish tails. My kids and husband couldnโt get enough!
