Step‑by‑Step Instructions for Cajun Shrimp Fettuccine Alfredo

Step 1: Boil the Pasta
Begin by bringing a large pot of salted water to a rolling boil over high heat. Add a drizzle of olive oil to prevent sticking. Once boiling, add the fettuccine and cook according to the package directions until al dente, approximately 8-10 minutes. Drain the pasta in a colander and set aside, ensuring to reserve a cup of pasta water for later use.

Step 2: Cook the Shrimp
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the peeled and deveined shrimp, then sprinkle with Cajun seasoning, salt, and pepper, ensuring the shrimp is well-coated. Sauté for about 2-3 minutes until the shrimp turns pink and opaque. Once cooked, remove the shrimp from the skillet and set aside, allowing the skillet to retain the flavorful drippings.

Step 3: Prepare the Sauce
Using the same skillet, reduce the heat slightly and add 3 tablespoons of butter. Let it melt before adding cream cheese, stirring until softened and well incorporated. Gradually pour in 1 cup of heavy cream, then add garlic powder, Italian seasoning, and a pinch of salt and pepper. Whisk continuously, bringing the mixture to a low simmer, creating a luscious base for your Cajun Shrimp Fettuccine Alfredo.

Step 4: Thicken the Sauce
Allow the sauce to simmer gently for about 8-10 minutes, stirring occasionally. Keep an eye on it as you want it to thicken without boiling vigorously. Once it reaches a creamy consistency, incorporate ½ cup of freshly grated Parmesan cheese, whisking until melted and smooth. Adjust the seasoning to your taste, ensuring a perfect balance of flavors.

Step 5: Combine the Shrimp and Sauce
With the sauce ready, carefully add the cooked shrimp back into the skillet. Gently toss the shrimp in the sauce, ensuring each piece is coated with the creamy goodness. Allow it to warm through for another minute or two, enriching the flavors of your Cajun Shrimp Fettuccine Alfredo.

Step 6: Mix with Fettuccine
Add the drained fettuccine to the skillet, using tongs or a spatula to toss everything together. If the sauce is too thick, add a splash of reserved pasta water to achieve your desired consistency. The creamy sauce should cling to every strand of pasta, creating a delightful harmony of textures and flavors.

Step 7: Serve and Garnish
Once everything is combined, it’s time to plate your delicious Cajun Shrimp Fettuccine Alfredo. Serve hot, garnishing with freshly chopped parsley and additional Parmesan cheese, if desired. The vibrant colors and creamy sauce make for an irresistible dish that’s sure to impress family and friends!

Expert Tips

Perfect Shrimp: Cook shrimp just until pink; overcooking can make them tough. This ensures the Cajun Shrimp Fettuccine Alfredo has tender pieces for a delightful texture.
Simmer Gently: Allow the sauce to thicken over low heat and avoid boiling vigorously. A gentle simmer develops deep flavors while maintaining creaminess in your Alfredo.
Season to Taste: Spice levels can vary with different Cajun seasonings. Taste as you go to adjust the heat and ensure your Cajun Shrimp Fettuccine Alfredo is perfectly flavored.
Pasta Water Magic: Reserve some pasta water before draining. If the sauce thickens too much, add a splash to loosen it, ensuring everything blends beautifully.
Customize with Veggies: Feel free to add vegetables like bell peppers or spinach for added nutrition and color. A touch of greenery can elevate your dish even more!

Make Ahead Options

These Cajun Shrimp Fettuccine Alfredo are perfect for meal prep enthusiasts! You can cook the fettuccine and sauté the shrimp up to 24 hours in advance, storing them separately in airtight containers in the refrigerator to maintain their texture and flavor. The creamy Alfredo sauce can also be prepared and refrigerated for up to 3 days, but be sure to allow it to cool completely before storing. When you’re ready to serve, simply reheat the sauce gently on the stove, adding a splash of cream if needed to restore its creaminess, then toss it with the shrimp and fettuccine. This way, you can enjoy restaurant-quality results with minimal last-minute effort!

How to Store and Freeze Cajun Shrimp Fettuccine Alfredo

Fridge: Store leftovers in an airtight container for up to 3 days. To maintain creaminess, reheat gently on the stove, adding a splash of cream if needed.

Thawing: When ready to enjoy, thaw overnight in the fridge. Reheat slowly on the stovetop, adding a bit of heavy cream or pasta water as needed to restore the sauce’s consistency.

Reheating: Heat gently over low-medium heat, stirring frequently to avoid separation of the sauce in your Cajun Shrimp Fettuccine Alfredo.
