Preparation steps

With all your ingredients ready, it’s time to jump into the fun part—cooking your crawfish fettuccine!

Step 1: Cook the Fettuccine  

Drain the pasta in a salty water, toss it with a bit of butter or olive oil to prevent sticking, and set it aside.

Step 2: Sauté the Holy Trinity  

Melt 3 tablespoons of butter. Add the onion, bell pepper, and celery—the “holy trinity” of Southern cuisine—and cook for 5 minutes, stirring occasionally, until softened.

Step 3: Build the Sauce  

Stir in the diced tomatoes, Cajun seasoning, smoked paprika, salt, and black pepper.Allow it to simmer for 2-3 minutes to combine the flavors. Then, lower the heat and gradually add the heavy cream. Stir until the mixture is smooth.

Step 4: Melt the Cheese  

Gradually add the shredded pepper jack cheese and grated Parmesan, stirring constantly until the cheeses melt and form a creamy sauce.

Step 5: Add the Crawfish  

Gently fold in the crawfish tails, ensuring they’re coated with the sauce. Cook for 3-5 minutes until the crawfish is heated through.

Step 6: Combine and Serve  

Add the cooked fettuccine to the skillet, tossing gently to combine. Sprinkle with fresh parsley and an optional dash of hot sauce for extra kick. Serve immediately and enjoy every creamy Cajun bite!

Cooking Tips

Cook’s Notes

  • Use fresh or frozen crawfish, but ensure they’re thawed and drained if frozen.  
  • For a milder flavor, substitute pepper jack cheese with mozzarella or cheddar.
  • When cooking the pasta, reserve some of the pasta water—it can help thin out the sauce if needed.

Variations/Substitutions

Looking to customize your Cajun pasta dish? Try these ideas:

  • Protein Swap: Use shrimp, crab, or chicken instead of crawfish.
  • Vegetarian Option: Replace crawfish with sautéed mushrooms or zucchini for a veggie-packed version.
  • Spice Adjustment: If you prefer less heat, reduce the Cajun seasoning and omit the hot sauce. For more spice, add sliced jalapeños or an extra pinch of cayenne.
  • Alternative Pasta: Substitute fettuccine with penne, linguine, or even zucchini noodles for a low-carb option.

Equipment Needed

  • Large pot for boiling pasta  
  • Large skillet or sauté pan
