Cajun Shrimp Alfredo Pasta Ingredients
For the Pasta
• Fettuccine – This pasta provides a perfect base; feel free to substitute with your favorite type of pasta if desired.
For the Shrimp
• Shrimp (1.5 lb. jumbo or large) – Ensure the shrimp is peeled and deveined for ease of cooking and best flavor.
For the Seasoning
• Cajun Seasoning (2 tsp.) – This spice blend adds the necessary heat and depth; brands like Old Bay or Tony Chachere’s work wonderfully.
• Cayenne Pepper (1/2 tsp., optional) – Kick up the heat with this addition; omit if you prefer a milder flavor.
• Onion Powder (2 tsp.) – Boosts the overall flavor profile of the dish.
• Garlic Powder (1 tsp.) – Imparts aromatic depth to the dish.
• Smoked Paprika (2 tsp.) – Adds a delightful smoky essence that complements Cajun flavors.
For the Sauce
• Cooking Oil (2 tbsp.) – Use grapeseed, olive, or avocado oil for searing the shrimp efficiently.
• Butter (4 tbsp., unsalted) – Creates a rich, creamy texture in the sauce.
• Garlic (2 tbsp., minced) – Fresh garlic provides a burst of flavor essential to the sauce.
• Flour (1 tbsp.) – Helps thicken the sauce and forms the roux base.
For the Creamy Base
• Chicken Broth (1 cup) – Contributes savory goodness; low-sodium broth can be used for a lighter touch.
• Heavy Cream (2 cups) – This is key for creating that luscious, creamy sauce.
• Lemon Juice (1 tbsp.) – The secret ingredient that brings brightness and balances the richness of the cream.
• Lemon Zest (1 tsp.) – Enhances the lemon flavor, adding a refreshing note.
• Parmesan Cheese (1/2 cup, freshly grated) – Gives richness and creaminess, a must for Alfredo.
For Garnishing
• Fresh Parsley (2 tbsp., chopped) – A sprinkle for freshness, color, and a final touch of flavor.
• Salt & Pepper – To taste; use with caution as Cajun seasoning contains salt already.
Step‑by‑Step Instructions for Cajun Shrimp Alfredo Pasta
Step 1: Season Shrimp
In a mixing bowl, combine your peeled and deveined shrimp with smoked paprika, garlic powder, onion powder, and Cajun seasoning. Mix until shrimp are thoroughly coated. Set this flavorful shrimp aside as you prepare the pasta. The spices will enhance the Cajun Shrimp Alfredo Pasta with a bold aroma that will have your taste buds tingling.
Step 2: Cook Pasta
Bring a large pot of salted water to a boil. Add the fettuccine, cooking according to package instructions until al dente, usually about 8-10 minutes. Once cooked, carefully drain the pasta, reserving about a cup of the pasta water. This starchy water can be added later to adjust the sauce consistency if needed.
Step 3: Sear Shrimp
In a skillet over medium-high heat, heat 2 tablespoons of cooking oil along with 1 tablespoon of butter. Once hot, add the seasoned shrimp in a single layer, cooking for about 3 minutes on each side until they turn pink and opaque. Remove the shrimp from the skillet and set them aside, keeping the skillet warm for the sauce preparation.
Step 4: Make Roux
Lower the heat to medium and add the remaining 3 tablespoons of butter to the skillet. Once melted, whisk in 1 tablespoon of flour, stirring continuously for about 1-2 minutes until it forms a smooth roux and turns a light golden color. This step is crucial for thickening the sauce of your Cajun Shrimp Alfredo Pasta.
Step 5: Create Sauce
Gradually pour in 1 cup of chicken broth and 2 cups of heavy cream while whisking to combine. Bring the mixture to a gentle simmer, stirring consistently to prevent lumps. As it thickens, add in the lemon juice, lemon zest, minced garlic, and a sprinkle of Cajun seasoning while tasting for balance, ensuring the sauce hits just the right spot.
Step 6: Finish Sauce
Allow the sauce to simmer uncovered for 10 minutes, stirring occasionally. As it thickens, mix in half a cup of freshly grated Parmesan cheese and 2 tablespoons of chopped parsley. Let it simmer for another 5 minutes, allowing the flavors to meld beautifully while achieving a rich and creamy texture in your Cajun Shrimp Alfredo Pasta.
Step 7: Combine
Once the sauce is perfectly thick, add the drained fettuccine to the skillet and toss gently until the pasta is well coated with the creamy sauce. Add the seared shrimp on top, folding them into the dish. If the sauce is too thick, you can incorporate a little reserved pasta water to achieve the desired consistency.
Step 8: Serve
Plate your delicious Cajun Shrimp Alfredo Pasta, garnishing with additional chopped parsley and a sprinkle of Cajun seasoning, if desired. Serve this dish warm, letting its captivating aroma fill your kitchen, and get ready to impress your family with this quick yet delightful meal.

Cajun Shrimp Alfredo Pasta Recipe FAQs
How do I choose the right shrimp for this recipe?
Absolutely! When selecting shrimp, look for fresh or frozen jumbo or large shrimp, ensuring they are peeled and deveined for convenience. If using frozen shrimp, thaw them in the refrigerator overnight or quickly in cold water for about 15-20 minutes. Avoid shrimp with dark spots or a fishy smell—these are indicators they may not be fresh!
How should I store leftovers?
I recommend storing any leftover Cajun Shrimp Alfredo Pasta in an airtight container in the fridge for up to 3 days. This helps maintain its freshness. If you want, reheat gently over low heat and add a splash of cream or pasta water to restore creaminess.
Can I freeze this Cajun Shrimp Alfredo Pasta?
Absolutely! You can freeze this dish for up to 2 months. To do this, portion out the pasta and sauce in airtight containers or freezer bags. When you’re ready to eat, thaw overnight in the refrigerator and reheat in a saucepan over medium heat, adding a bit of cream or chicken broth to help with consistency.
What should I do if my sauce is too thick?
No stress! If your sauce turns out too thick, simply add a splash of the reserved pasta water or some additional heavy cream while stirring until it reaches your desired consistency. Additionally, keep the heat low to prevent the sauce from burning while you make these adjustments.
Is this recipe suitable for individuals with dietary restrictions?
Very much so! If you’re making this dish for someone with gluten sensitivities, you can easily use gluten-free pasta. For dairy allergies, substitute heavy cream with coconut cream or a non-dairy cream alternative. Just be mindful of Cajun seasoning, as it may contain allergens—check the label before using!
How can I enhance the Cajun flavor?
To intensify the Cajun essence, try adding more Cajun seasoning or even a pinch of cayenne pepper to increase the heat. If you enjoy extra spice, tossing in some chopped jalapeños or a dash of hot sauce when serving can also give it that delightful kick you’re looking for.
These tips will ensure your Cajun Shrimp Alfredo Pasta is as delicious and satisfying as possible! Enjoy cooking and savor every bite!
