Cooking Cajun Shrimp Fettuccine Alfredo: The Process

Step 1: Cook the Fettuccine
Start by bringing a large pot of salted water to a boil. Add the fettuccine pasta and cook according to the package instructions until al dente. Once cooked, reserve about 1 cup of the pasta water, then drain the fettuccine in a colander and set aside.
Step 2: Sauté the Sausage
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced Andouille sausage and cook for about 3-4 minutes, or until nicely browned. The sausage adds a smoky flavor that complements the shrimp perfectly.
Step 3: Add the Shrimp
Once the sausage is cooked, add the shrimp to the skillet. Sprinkle the Cajun seasoning over the shrimp and toss to coat. Cook for about 2-3 minutes, or until the shrimp turns pink and opaque. Be careful not to overcook; shrimp can become rubbery if left on the heat too long.
Step 4: Incorporate Aromatics
Add the diced onion and minced garlic to the skillet. Sauté for an additional 2-3 minutes, until the onions are translucent and fragrant. This step builds layers of flavor that are crucial for a delicious sauce.
Step 5: Create the Sauce
Pour in the chicken stock and bring the mixture to a gentle simmer. Allow it to cook for about 2 minutes to reduce slightly. Then, add the heavy cream, stirring well to combine. Let it simmer for another 3-5 minutes, allowing the sauce to thicken.
Step 6: Add the Cheese
Gradually stir in the grated Parmesan cheese, black pepper, and cayenne pepper. Keep stirring until the cheese has melted and the sauce is smooth and creamy. If the sauce is too thick, add a little reserved pasta water to achieve your desired consistency.
Step 7: Combine Pasta and Sauce
Add the cooked fettuccine to the skillet, tossing to coat the pasta evenly with the creamy Cajun sauce. Ensure every strand of fettuccine is enveloped in that rich, flavorful sauce!
Step 8: Garnish and Serve
Once everything is combined, remove the skillet from heat. Serve the Cajun Shrimp Fettuccine Alfredo hot, garnished with fresh minced parsley for a pop of color and freshness. Enjoy your meal!
Swap Guide

- If you prefer a lighter option, substitute half-and-half or whole milk for the heavy cream.
- For a vegetarian version, replace the shrimp and sausage with sautéed mushrooms or a mix of your favorite vegetables.
- Use whole wheat fettuccine for a healthier pasta alternative.
- If you can’t find Andouille sausage, any smoked sausage will work just as well.
Easy-to-Miss Gotchas
When making Cajun Shrimp Fettuccine Alfredo, it’s essential to not overcook the shrimp. They should be just cooked through; overcooking can lead to a rubbery texture that detracts from the dish. Additionally, be careful with the saltiness of the Cajun seasoning and sausage, as they can add considerable salt to the dish. Always taste as you go!
Save for Later: Storage Tips
If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, add a splash of chicken stock or cream to loosen the sauce and warm gently on the stovetop. Be cautious not to overheat, as this can make the shrimp tough.
Handy Q&A
Can I use frozen shrimp for this recipe?
Yes, frozen shrimp can be used. Just make sure to thaw them completely before cooking. You can leave them in the refrigerator overnight or run them under cold water for a quicker thawing method.
What can I serve with Cajun Shrimp Fettuccine Alfredo?
This dish pairs beautifully with a simple green salad, garlic bread, or roasted vegetables to balance out the richness of the Alfredo sauce.
Can I make this dish in advance?
While it’s best served fresh, you can prepare the sauce ahead of time and store it in the refrigerator. Just reheat it gently and toss it with the freshly cooked pasta and shrimp when ready to serve.
How can I adjust the spice level?
If you prefer a milder flavor, reduce the amount of Cajun seasoning and cayenne pepper. You can always add more spice later if desired, so start with less and adjust to your taste!
