Step-by-Step Instructions
Cooking the Pasta
To start, fill a large pot with water and add salt. Bring it to a boil. Once boiling, add 8 ounces of fettuccine pasta. Cook it according to the package directions until it’s al dente. This usually takes about 8-10 minutes. After cooking, drain the pasta but save a cup of the pasta water for later.
Seasoning and Sautéing the Shrimp
Next, take 1 pound of shrimp, already peeled and deveined. In a medium bowl, add 2 tablespoons of Cajun seasoning. Toss the shrimp in the seasoning until they’re fully coated. Now, heat 3 tablespoons of olive oil in a large skillet over medium-high heat. Once it shimmers, add the shrimp in a single layer. Cook them for 2-3 minutes on each side until they turn pink. Remove them from the skillet and set them aside.
Preparing the Alfredo Sauce
In the same skillet, reduce the heat to medium. Add 2 tablespoons of unsalted butter. Once it melts, toss in 3 cloves of finely minced garlic. Sauté the garlic for about 1 minute until it smells good. Slowly pour in 1 cup of heavy cream. Stir it gently and let it simmer for a bit.
Combining Pasta and Sauce
Now, it’s time to make the sauce creamy. Gradually whisk in 1 cup of freshly grated Parmesan cheese. Keep stirring until the cheese melts and the sauce is smooth. If the sauce is too thick, add a splash of that reserved pasta water until you reach your desired consistency. Taste the sauce and add salt and freshly ground black pepper as needed.
Serving and Garnishing
Finally, add the cooked fettuccine directly into the Alfredo sauce. Toss the pasta gently to coat it well. Then, fold in the sautéed shrimp, being careful not to break them. Plate your Cajun Shrimp Alfredo while it’s hot. Sprinkle freshly chopped parsley on top for a burst of color and taste. Enjoy!
Tips & Tricks
Tips for Perfectly Cooked Shrimp
To cook shrimp just right, start with fresh, large shrimp. They taste better and cook evenly. When you season shrimp, coat them well with Cajun seasoning. This adds great flavor. Heat your skillet until it shimmers before adding the shrimp. This helps them sear nicely. Cook them for only 2-3 minutes per side. Watch for them turning pink. Overcooked shrimp become tough and rubbery. Once done, remove them right away to keep their juicy texture.
Enhancing the Alfredo Sauce
For a rich Alfredo sauce, use heavy cream. It gives a nice creamy texture. After melting the butter, add garlic for flavor. Cook it until fragrant but don’t let it brown. This can make the sauce bitter. Gradually whisk in Parmesan cheese. This keeps the sauce smooth. If it gets too thick, add a splash of reserved pasta water. This helps achieve the perfect consistency. Taste the sauce and adjust salt and pepper for balance.
Best Practices for Cooking Fettuccine
To cook fettuccine well, use a large pot with plenty of water. Add salt to the water; this adds flavor to the pasta. Cook the pasta until it is al dente, which means it should have a slight bite. Drain it but save some pasta water. This water can help adjust your sauce later. Toss the pasta with the sauce right after draining to keep it warm and flavorful.
Pro Tips
- Perfect Pasta Texture: Make sure to cook the fettuccine until it’s al dente. This will ensure the pasta holds up well in the sauce and doesn’t become mushy.
- Fresh Ingredients: Using fresh shrimp and freshly grated Parmesan cheese will elevate the flavor of your Cajun Shrimp Alfredo significantly compared to pre-packaged options.
- Adjusting Sauce Consistency: If your Alfredo sauce becomes too thick, simply add a splash of the reserved pasta water to achieve your desired creamy consistency.
- Garnish for Flavor: Don’t skip the fresh parsley garnish! It not only adds a pop of color but also a burst of fresh flavor to your dish.

Variations
Adding Vegetables
You can boost the nutrition by adding veggies. Bell peppers, spinach, and zucchini work well. Just sauté them in the same skillet after cooking the shrimp. This adds color and flavor. You can use about 1 to 2 cups of mixed vegetables. Make sure they are tender before adding to the pasta.
Different Protein Options
If shrimp isn’t your thing, try chicken or sausage. Chicken breast can be grilled or sautéed. Slice it thin for even cooking. Sausage, especially andouille, gives a nice kick. Use about 1 pound of either protein. Cook them the same way as the shrimp for great flavor.
Alternative Sauces and Seasonings
Experiment with different sauces and spices. A creamy garlic sauce makes a great base too. You can also use a Cajun alfredo mix. This way, you keep the Cajun flair but change the sauce. Consider adding a splash of lemon juice for some brightness.
Storage Info
How to Store Leftovers
To store your Cajun Shrimp Alfredo, let it cool down first. Place it in an airtight container. You can keep it in the fridge for up to three days. Make sure to label the container with the date. This helps you track how old it is.
Reheating Instructions
When you’re ready to eat the leftovers, use a skillet for the best results. Warm it over low heat. Add a splash of water or cream to help the sauce. Stir gently until it’s hot. You can also use a microwave. Heat it in short bursts, stirring in between, until warm.
Freezing Cajun Shrimp Alfredo
If you want to freeze it, first cool it completely. Use freezer-safe containers or bags. Remove as much air as possible to prevent freezer burn. It can stay in the freezer for up to three months. When ready to eat, thaw it in the fridge overnight before reheating.
FAQs
Can I use frozen shrimp?
Yes, you can use frozen shrimp. Just thaw them first. Place them in the fridge overnight or run them under cold water. This helps them cook evenly. Frozen shrimp is a good option if fresh shrimp is not available.
What can I substitute for heavy cream?
You can use half-and-half or whole milk mixed with butter. For a lighter option, try using Greek yogurt or coconut milk. Each will change the flavor a bit but still keep the sauce creamy.

Cook the Pasta: Begin by bringing a large pot of salted water to boil. Add the fettuccine and cook according to the package instructions until it reaches al dente texture. Once done, drain the pasta and set it aside, reserving a cup of the pasta water in case you need to adjust your sauce consistency later.
Season the Shrimp: In a medium mixing bowl, combine the peeled and deveined shrimp with Cajun seasoning. Toss them gently until each shrimp is evenly coated with the seasoning.
Sauté the Shrimp: In a large skillet, heat the olive oil over medium-high heat until shimmering. Add the seasoned shrimp to the skillet in a single layer, making sure not to overcrowd them. Sauté for about 2-3 minutes on each side or until they turn pink and opaque. Once cooked, remove the shrimp from the skillet and set aside on a plate.
Prepare the Alfredo Sauce: In the same skillet, lower the heat to medium and add the unsalted butter. Once melted, stir in the minced garlic and sauté for about 1 minute, just until fragrant and lightly golden. Carefully pour in the heavy cream and allow it to come to a gentle simmer, stirring occasionally.
Combine Ingredients: Gradually whisk in the freshly grated Parmesan cheese, stirring continuously until the cheese is fully melted and the sauce is smooth and creamy.
