Crawfish Fettuccine Flip

There ought to be a Hallelujah chorus sung every time a dish of hot and bubbly Crawfish Fettuccine comes out of the oven. I was in my late teens when I first put a bite of this rich, cheesy pasta blessed with crawfish in my mouth. I couldn’t get enough of it! The crawfish fettuccine did not become popular until the late seventies. My guess is that one day some Cajun flipped a classic Italian favorite by adding some crawfish, the Cajun trinity and some heat to it. Clever! 

I took a recipe Mamma uses and changed it a bit. My goal these days is cooking with some healthier lower processed ingredients. If you think about it anytime we start messin’ with our food we are processing it away from its most natural state. So instead of the canned cream soup, I used half and half, butter and flour and instead of the processed cheese I used some cheddar and cream cheese. Here it is:

Easy Cooking Steps

Cooking the Cajun trinity in butter gives this cheesy cream sauce the start it needs. It provides the fettuccine sauce with a rich taste before adding the crawfish.

Using fresh chicken broth means cooking with lower processed foods. I use cheddar and cream cheeses instead of processed cheese.

Add the fettuccine right from the pasta pot without draining into the cream sauce.

The breadcrumbs are optional, but I like the extra crunch it adds after baking.

You cannot change reality, but you can control the manner in which you look at things. Your attitude is under your own control. Weed out the negative and focus on the positive!
