Creamy Cajun Shrimp Pasta
Our creamy Cajun Shrimp Pasta takes the bold taste of my Cajun shrimp and Bang Bang shrimp recipes and transforms it into a rich, comforting, creamy pasta dish with a tomato alfredo sauce twist. The creamy cajun sauce serves as the perfect foundation for this flavorful meal, with its thick, velvety texture perfectly coating each piece!

Ingredients
- Penne pasta: Any short pasta will work for this recipe. I prefer rigatoni, ziti, elbow pasta, or bow-tie if I do not have penne.
- Shrimp: Use fresh or frozen large shrimp that’s been peeled, deveined and have tails removed.
- Creole (Cajun) seasoning: I used a store-bought cajun seasoning (use your favorite brand, like McCormick’s, Ragin’ Cajun, Louisiana, and Tony Chachere’s Original), but you can make your own cajun seasoning with a mix of smoked paprika, salt, garlic powder, onion powder, cayenne pepper, and oregano.
- Olive oil
- Unsalted butter
- Minced garlic
- Fire roasted diced tomatoes: You can substitute the can of fire roasted tomatoes with plain diced tomatoes or diced tomatoes with peppers and onions (such as Rotel). Keep in mind that if using a tomato substitute that contains added peppers and onions, it will increase the spice or heat level of the sauce.
- Heavy cream: You can substitute the heavy cream with half & half or whole milk for a lighter sauce. I do not recommend using low or non-fat milk as you will not get a thick sauce.
- Parmesan cheese: You can substitute the grated parmesan cheese for a grated pecorino-romano or a four-cheese Italian blend. Any of these, or any combination, will taste delicious in this recipe.
- Fresh parsley

How to Make Cajun Shrimp Pasta (Step-by-Step)
- Prepare The Pasta: In a large pot on high heat, boil and drain the pasta according to the package instructions for al dente. Set aside.
- Season the Shrimp: Toss the shrimp and Cajun seasoning together in a bowl to coat.
- Saute the Shrimp: Heat the olive oil and butter in a large skillet over medium-high heat until melted. Add the seasoned shrimp and garlic and cook until the shrimp turn pink and opaque. Transfer to a clean plate and set aside.
- Simmer the Sauce: Reduce the heat to medium-low. Add the tomatoes, heavy cream, parmesan, and remaining cajun seasoning to the same skillet. Stir to combine. Allow the sauce to simmer until it begins to thicken.
- Combine To Coat: Add the prepared pasta to the skillet along with half of the cooked shrimp, including the juices from the plate. Stir to coat the pasta and shrimp with the sauce.
- Serve: Remove from the heat, top with the remaining shrimp, and sprinkle with grated Parmesan cheese and freshly chopped parsley. Serve warm and enjoy!

Tips & Variations
- Avoid Overcooking Shrimp: Cook shrimp just until they turn a deep pink color, about 2-3 minutes per side. Overcooking can make them tough.
- Adjust the Cajun Spice Level: Start with a little Cajun seasoning and taste as you go. Add more for heat, or reduce it for a milder dish.
- Perfect Creamy Texture: The key to an ultra-creamy shrimp pasta sauce is using a combination of heavy cream and Parmesan cheese. This creates a rich, velvety coating that sticks to the shrimp and pasta. Mix a dollop of cream cheese or mascarpone into the sauce for extra creaminess. If it’s too thick, thin it out with reserved pasta water for the perfect consistency.
- Sausage, anyone? Incorporate andouille sausage to add some additional protein. This will give the dish a smoky, spicy flavor and add another layer of depth.
Best Pasta for Cajun Shrimp Pasta
- Long Noodles (like Fettuccine or Linguine): Longer noodles provide a luxurious, elegant feel, and their length allows for a great sauce-to-pasta ratio. Long noodles work well if you prefer a lighter, more delicate texture.
- Short Noodles (like Penne or Rigatoni): Short noodles with ridges or tubes tend to trap more sauce inside, offering a heartier, more substantial bite. They work well if you prefer a heavier bite with each forkful.

Serving Suggestions
This shrimp and pasta dish is perfect on its own, but if you want to add some extra nutrients, serve it with a side of steamed veggies or salad. For a lower carb count, consider swapping the pasta for zucchini noodles, cauliflower breadsticks, or broccoli slaw.
Storage and Reheating Instructions
- To Store: Leftovers can be stored in an airtight container in the refrigerator for up to 2 days.
- To Freeze: I do not recommend freezing this Cajun shrimp pasta. The texture of the shrimp tends to get tough once frozen and then thawed and the pasta becomes too mushy.
- To Reheat: Leftovers can be reheated in a skillet over medium-low heat until the pasta and shrimp are warmed through. You may need to add a splash of water or chicken broth to the skillet to thin the sauce when reheating.
