What is a crawfish?

A crawfish is a crustacean that is mostly harvested in the Southern United States. The body looks similar to a lobster, but it is much smaller.

The majority of the meat is located in the tail or abdomen of the shellfish.

While it’s really common to cook the crawfish whole, especially when throwing a Crawfish Boil, this recipe uses pre-cooked tail meat. The meat has already been removed from the shell, which makes assembly much quicker.


Ingredients

crawfish fettuccine ingredients: Cajun seasoning, cream, oil, flour, butter, green onions, parmesan cheese, fettuccine noodles, clam juice, crawfish tails, shrimp, garlic, red pepper, white onion.
  • Fettuccine Noodles: You can use dry pasta or fresh pasta. Cook according to the package directions.
  • Crawfish Tail Meat: Look for frozen packaged Louisiana crawfish tails. It will save you a lot of time in preparation. Be sure to thaw them first.
  • Cajun or Creole Seasoning: This is a blend of salt, pepper, garlic, onion, chiles and herbs. Depending on how much salt is in the Cajun seasoning you choose, you may want to add more salt and pepper to the final dish.
  • White Onion
  • Red Pepper
  • Garlic
  • Flour: This is used to make the roux, which thickens the sauce. I recommend using all-purpose flour.
  • Clam Juice: Clam juice can be found in a small bottle by the canned meat and tuna or purchased online.
  • Heavy Cream: This is the key to making the super rich, creamy sauce.
  • Parmesan Cheese: For the best results, use fresh shaved Parmesan cheese, which can be found in the deli section of your grocery store.
  • Shrimp: Buy uncooked shrimp that is peeled and deveined.
  • Olive Oil and Butter
  • Green Onions: This gets added at the end to add color, crunch and freshness to the pasta.

Substitutions: You can substitute the clam juice with seafood stock or chicken broth.

How to cook the fettuccine

Fettuccine noodles are long like spaghetti noodles, but they are about 1/4-inch wide and flat.

For this recipe, you will only need 8 ounces of uncooked fettuccine noodles. Most boxes contain 16 ounces or 1 pound of noodles. So you’ll only need 1/2 a box.

  1. STEP ONE: Bring a large pot of water to a boil. Add a generous pinch of salt to the water to flavor it.
  1. STEP TWO: Place the fettuccine noodles in the pot and stir. If using dry pasta, cook for about 12 minutes, stirring occasionally. If using fresh pasta, cook for about 2 minutes. Once cooked, the noodles should be al dente, which means soft with a little chew.

PRO TIP: Although Italians would tell you to never break your pasta before boiling it, if your noodles are too long to fit in the pot you chose, it’s okay to break them in half. The only down side to breaking them is that they will be shorter, so they won’t spin around your fork as easily.

  1. STEP THREE: Remove the noodles from the pot and set aside.

Make the crawfish Alfredo sauce

  1. STEP ONE: Place a large skillet on the stove or on the grill over medium-high heat. Add 1 tablespoon olive oil and 2 tablespoon butter. Once melted, add diced onion and red bell peppers and cook until tender. Add in the minced garlic and sauté for about 30 seconds.

Frequently Asked Questions

Where can I buy crawfish tail meat?

You may be able to find crawfish tail meat in the freezer section of your grocery store near the other frozen seafood. It comes in a pouch. I have the best luck finding it at Wal-Mart. If your Wal-Mart or grocery store doesn’t carry it, you can also order it online.

What side dish goes with crawfish fettuccine?

Crawfish fettuccine is a hearty dish all on its own. It has vegetables, pasta and seafood. If you would like to serve something alongside it, I recommend a light house salad or some crusty bread with garlic butter.

Can crawfish fettuccine be frozen?

Yes. Once this delicious recipe cools, you can store it in an airtight container and freeze it for a couple of months.

Every brand of Cajun seasoning is made a little differently, which is why I didn’t give exact measurements for salt and pepper. Once your pasta dish is complete, taste the sauce and add salt and pepper to taste.
