Recipe walkthrough: Instructions

This is an overview of the recipe steps. For more detailed instructions visit the recipe card at the bottom of this post.

A large pot of water being boiled with some seasoning.
Step 1: Add the seafood seasoning (crab boil) to a pot of water and bring to a boil.
Cooked Fettuccine in a pot with a pasta spoon.
Step 2: Add the fettuccine pasta and cook 8-9 minutes, until al dente per package instructions. Drain then set aside. Keep some of the pasta water for later.
A skillet with a stick of butter.
Step 3: Add the stick of butter to a skillet and apply medium-high heat until melted.
A skillet with melted butter and onions.
Step 4: Add the shallots and garlic and cook until translucent, just a few minutes.
A skillet with some cheese sauce added with some tomatoes.
Step 5: Add the chicken soup, Creole seasoning, tomatoes and chilies and Worcestershire sauce. Give a good stir and allow to come to a boil over medium heat.
Cubes of velveeta added to a skillet making a cheese sauce.
Step 6: Add the Velveeta Cheese, chopped into cubes and stir continuously to allow to melt into the shallots mixture.
Crawfish tails and chopped green onions in a skillet with a cheesy sauce.
Step 7: Add the crawfish tails and green onions and cook another 2 minutes.
Cooked fettuccine added to a crawfish cheese sauce.
Step 8: Add the cooked Fettuccine to the crawfish mixture and stir into the sauce to combine well. Remove from the heat, cover with foil and place in a preheated oven (350°F) for about 15 minutes. Remove and serve.

Hint: Adding the seafood seasoning to the water when cooking the fettuccine noodles will help give this Crawfish Fettuccine recipe more depth of flavor.

Recipe variations and substitute ideas

  • Pasta - obviously, just because it's called crawfish fettuccine doesn't mean you absolutely have to stick to that particular noodle. I know a lot of people that use bowtie pasta for this dish too!
  • Flour - if you're not much of a cream of soup fan you could go down the road of making a light roux etc.
  • Heavy Cream - same as above, if you're trying to get away from the cream of soup you might want to try using cream instead. You'll have to adjust for flavor though.
  • Shrimp - instead of crawfish you could swap it out and make this recipe a shrimp fettuccine.
  • Onions - if you prefer a stronger onion flavor you could swap out the shallots for yellow onion, or sweet onion even.
  • Cajun Seasoning - I'm asked this often. Can I use Cajun seasoning instead of Creole Seasoning. It's almost the same thing - yes, they interchange well.
  • Smoked sausage - you could add smoked sausage to this dish and it be delicious.
  • Mild Rotel - keep the dish a little milder and use this version of rotel.
  • Parmesan cheese - sprinkle with a little parmesan when serving.
  • Red Bell Pepper - this would add an excellent sweetness.
  • Sour Cream - you could try replacing some of the Velveeta with sour cream.

Necessary gear: Equipment

You'll need a large skillet that is oven proof - a cast iron skillet is great for this crawfish fettuccine recipe! Otherwise, you could prepare it in a skillet and then transfer to a casserole dish to finish off in the oven.

This recipe would cook excellently in a Dutch Oven too.

How to store leftovers

Once this dish has cooled completely it will need to be stored in an airtight container in the refrigerator - it will be good for up to 3 days.

This recipe does actually freeze well. Store in a freezer safe container in the freezer for up to 3 months.

About Mel

Mel's kitchen notes

Using leftover crawfish from your crawfish boil is recommended as the crawfish are beautifully seasoned. If you don't have this option then frozen crawfish from the grocery store will suffice, but if you can, rather buy the Louisiana Crawfish Tails (not from China - they are tasteless.)
