Ingredients
When making Cajun Shrimp Alfredo, you need a few key ingredients. Here’s what you will need:
- 8 oz fettuccine pasta
- 1 lb shrimp, peeled and deveined
- 1 tablespoon Cajun seasoning
- 3 tablespoons unsalted butter
- 3 cloves garlic, minced
- 1 cup heavy cream
- 1 cup freshly grated Parmesan cheese
- Salt and freshly cracked black pepper to taste
- Fresh parsley, finely chopped (for garnish)
Each ingredient plays an important role. The fettuccine serves as the pasta base, holding onto the creamy sauce. The shrimp adds a nice protein punch. Cajun seasoning gives a kick of flavor, making this dish special. The butter and garlic form the base of the Alfredo sauce. Heavy cream creates the rich, smooth texture, while Parmesan cheese adds depth. Finally, salt and pepper balance the dish perfectly, and parsley brings a fresh touch.
These ingredients work together to create a meal that is not just tasty but also satisfying. Enjoy your cooking!

Step-by-Step Instructions
Cooking the Pasta
To cook the fettuccine, bring a large pot of salted water to a boil. Add the fettuccine and cook according to the package instructions until it is al dente. This means it should be firm but not hard. After cooking, drain the pasta. Be sure to save about 1/2 cup of the pasta water. This starchy water helps adjust the sauce later.
Preparing the Shrimp
For the shrimp, first peel and devein them. In a bowl, mix the shrimp with Cajun seasoning. Make sure each piece gets a good coat of spices. Heat a large skillet over medium heat. Melt 1 tablespoon of unsalted butter in the pan. Add the shrimp in a single layer. Sauté for 2-3 minutes on each side. You'll know they are done when they turn pink and opaque.
Making the Alfredo Sauce
In the same skillet, lower the heat to medium-low. Add 2 more tablespoons of butter and let it melt. Then, add the minced garlic and sauté for about 30 seconds. You want the garlic to be fragrant but not brown. Next, slowly pour in 1 cup of heavy cream. Stir gently until it simmers. Gradually whisk in 1 cup of freshly grated Parmesan cheese. Keep stirring until the cheese melts into a creamy sauce. If it gets too thick, stir in some reserved pasta water little by little until you reach the right consistency.
Combining Ingredients
Now, it's time to combine everything. Gently fold the cooked fettuccine and sautéed shrimp into the Alfredo sauce. Toss everything well so that every piece of pasta and shrimp is covered in the sauce. Taste the dish and adjust the seasoning with salt and freshly cracked black pepper if needed.
Tips & Tricks
Perfecting the Alfredo Sauce
To make a great Alfredo sauce, you want the right thickness. Start with the right amount of heavy cream. Cook it slowly on medium-low heat. If the sauce is too thick, use the reserved pasta water. Add a little at a time. This helps to get the perfect creamy texture. Stir it well after each addition to check how it looks.
Cooking the Shrimp
You can tell shrimp are cooked when they turn pink. They should look opaque and firm. Avoid overcooking them, as they can become rubbery. Cook shrimp about 2-3 minutes on each side. If they curl up tightly, they are overcooked. Keep an eye on the color change to know when they are ready.
Presentation Tips
Serve your Cajun Shrimp Alfredo in shallow bowls. This makes it look fancy. Sprinkle extra Parmesan cheese on top. Add a few sprigs of parsley for color. For a complete meal, include a slice of garlic bread on the side. This adds crunch and pairs well with the creamy dish. Enjoy your beautiful plate!
Pro Tips
- Perfectly Cooked Pasta: To achieve the best texture, always cook your fettuccine to al dente. This means it should be firm to the bite but not hard, ensuring it holds up well when mixed with the creamy sauce.
- Flavorful Shrimp: Let the shrimp marinate in the Cajun seasoning for at least 15 minutes before cooking. This allows the spices to penetrate the shrimp, enhancing the overall flavor of the dish.
- Adjusting Sauce Consistency: If your Alfredo sauce becomes too thick, gradually add the reserved pasta water. This starchy water not only helps thin the sauce but also helps it adhere better to the pasta.
- Garnish with Care: For an appealing presentation, add freshly chopped parsley just before serving. This not only adds a pop of color but also a fresh flavor that complements the richness of the dish.
Variations
Spicy Cajun Shrimp Alfredo
To add more heat to your Cajun Shrimp Alfredo, try these suggestions:
- Extra Cajun seasoning: Start by adding an extra teaspoon of Cajun seasoning to the shrimp. This packs more flavor and spice.
- Red pepper flakes: Sprinkle in some red pepper flakes while cooking the shrimp. This will give you a nice kick.
- Hot sauce: Drizzle hot sauce into the Alfredo sauce as it simmers. Adjust the amount to your heat preference.
- Jalapeños: Finely chop some fresh jalapeños and sauté them with the garlic for an extra layer of heat.
These options can transform your dish into a fiery delight!
Vegetarian Alfredo Option
If you're looking for a meatless version of this dish, consider these substitutions:
- Mushrooms: Use sautéed mushrooms instead of shrimp. They add a nice texture and flavor.
- Zucchini or bell peppers: Slice zucchini or bell peppers and sauté them. They will bring color and freshness to the dish.
- Plant-based cream: Swap heavy cream for a plant-based cream. This keeps the dish creamy without dairy.
- Nutritional yeast: Substitute Parmesan cheese with nutritional yeast for a cheesy flavor that’s vegan-friendly.
These changes allow you to enjoy a delicious Alfredo without meat!
Seafood Medley
Want to mix up your seafood? Here are some ideas to incorporate different types:
- Scallops: Add scallops along with shrimp for a sweet and rich flavor. Sauté them just like the shrimp.
- Crab meat: Fold in some cooked crab meat into the sauce. This adds a touch of luxury to your dish.
- Lobster: For a special occasion, add lobster meat. Cook it briefly to keep it tender.
- Fish: Diced white fish, like tilapia or cod, can also work well. Cook until the fish is flaky and tender.
These seafood options will take your Cajun Shrimp Alfredo to the next level!
Storage Info
Storing Leftovers
To keep your Cajun Shrimp Alfredo fresh, store leftovers in an airtight container. Make sure to let it cool completely before sealing it. This helps prevent condensation and keeps the dish from getting soggy. Place it in the fridge within two hours of cooking. Enjoy it within three to four days for the best taste.
Reheating Tips
When you want to reheat your Cajun Shrimp Alfredo, use a skillet over low heat. Add a splash of milk or cream to help the sauce stay creamy. Stir gently to warm it up without cooking the shrimp again. If you see the sauce separating, don't worry! Just whisk it a bit more while it heats. This helps bring it back together.
Freezing Instructions
Yes, you can freeze Cajun Shrimp Alfredo! But keep in mind, the shrimp may change texture. For freezing, use a freezer-safe container. Leave some space at the top, as the sauce will expand when frozen. You can freeze it for up to three months. When ready to eat, thaw it in the fridge overnight and reheat it gently on the stove.
FAQs
Can I use frozen shrimp?
Yes, you can use frozen shrimp. Just thaw them first. Place them in cold water for about 15-20 minutes. After thawing, peel and devein them if needed. Pat them dry with a paper towel before cooking. This helps the seasoning stick better.
What can I substitute for heavy cream?
If you want a lighter sauce, use half-and-half or whole milk. You can also mix milk with a little flour to thicken it. Coconut cream is another good choice for a dairy-free option. Just keep in mind that each substitute changes the flavor slightly.
