This creamy Cajun shrimp pasta with sausage combines the best of Cajun cuisine with Italian comfort food. The spicy kick from the seasonings balances perfectly with the rich, velvety sauce, while juicy shrimp and savory sausage make every bite memorable. I developed this recipe after visiting New Orleans and falling in love with the bold flavors of Cajun cooking.
This dish has become my go-to when entertaining guests who appreciate food with personality. I first made it when my brother visited after living in Louisiana for years, and he claimed it reminded him of his favorite restaurant back in New Orleans.
Ingredients
- Pappardelle pasta: Creates the perfect base for capturing the sauce in its wide ribbons
- Shrimp: Adds a delicate sweetness that pairs perfectly with the spicy elements
- Andouille sausage: Provides authentic Cajun flavor and a smoky depth
- Cajun seasoning: Brings the signature Louisiana heat and complexity
- Heavy cream: Creates the luxurious texture that makes this dish irresistible
- Parmesan cheese: Adds nutty richness and helps thicken the sauce
- Lemon juice: Brightens the entire dish with necessary acidity to balance the richness
Step-by-Step Instructions
- Prepare the pasta:
- Cook the pasta according to package directions until al dente. The texture is crucial since the pasta will continue cooking slightly in the sauce. Reserve about half a cup of starchy pasta water before draining this liquid gold will help create a silky sauce that clings to every strand.
- Season and cook the shrimp:
- Pat the shrimp completely dry with paper towels to ensure proper browning. Season generously with Cajun spice, making sure each piece is evenly coated. Cook in butter and oil until they turn pink and slightly curled, about two minutes per side. Removing them now prevents overcooking while you prepare the sauce.
- Brown the sausage:
- Slice the andouille sausage into medium-thick rounds and cook until they develop a deep brown crust on both sides. This caramelization creates another layer of flavor that will infuse the entire dish. Remove and set aside with the shrimp.
- Create the flavor base:
- In the same pan with all those beautiful browned bits, sauté diced onions and sliced garlic until the onions become translucent and soft. Take your time with this step around 5 minutes as it builds the foundation of your sauce.
- Develop the creamy sauce:
- Pour in the heavy cream and bring to a gentle simmer, not a rolling boil. Add the Cajun seasoning, lemon pepper, paprika, chili powder, sugar, and oregano, stirring constantly to blend the flavors. The sugar balances the heat, while the herbs add aromatic complexity.
- Integrate pasta and thicken:
- Add the cooked pasta and reserved pasta water to the simmering sauce. The starch in the water will help the sauce cling to every strand while achieving the perfect consistency. Add the lemon juice now to brighten all the flavors without curdling the cream.
- Reunite all components:
- Return the cooked shrimp and sausage to the pan, gently folding them into the pasta. Finish with a tablespoon of butter for glossiness and extra richness. Let everything marry together for just a minute more before serving.

The quality of your Cajun seasoning makes all the difference in this dish. I discovered this when I finally invested in authentic Louisiana Fish Fry Products seasoning after years of using generic blends. The depth of flavor was incomparable, with notes of paprika, garlic, and herbs that mass-market versions simply couldn't match.
Make Ahead and Storage
This Cajun pasta reheats beautifully, making it perfect for meal planning. Store leftover pasta in an airtight container in the refrigerator for up to three days. When reheating, add a splash of cream or even a bit of water to loosen the sauce as it will thicken considerably when cold. Warm gently over medium-low heat, stirring frequently to prevent the sauce from breaking. The flavors actually intensify overnight as the spices permeate the cream sauce more thoroughly.
Ingredient Substitutions
If pappardelle isn't available, fettuccine or linguine make excellent alternatives that still capture the sauce well. For a lighter version, substitute half and half for heavy cream, though the sauce won't be quite as rich. Turkey sausage can replace andouille for a leaner option with less heat. Vegetarians can skip the proteins entirely and add roasted bell peppers and mushrooms for a satisfying meatless version that still carries all the Cajun flavors. For those avoiding dairy, coconut cream provides a surprisingly compatible flavor that works with the spicy elements.
Serving Suggestions
Serve this Cajun pasta with a simple side salad dressed with vinaigrette to cut through the richness of the cream sauce. A piece of crusty garlic bread makes the perfect companion for soaking up every last bit of sauce. For a complete Louisiana-inspired meal, start with a small cup of gumbo or a few hushpuppies as an appetizer. To drink, a crisp Sauvignon Blanc or a light beer complements the spice without overwhelming the delicate shrimp flavor.

The Culture Behind Cajun Pasta
This fusion dish represents the beautiful marriage of Italian and Cajun cuisines that occurred naturally in Louisiana. When Sicilian immigrants arrived in New Orleans in the late 19th century, they brought their pasta traditions which soon incorporated local ingredients and flavors. The holy trinity of Cajun cooking onions, bell peppers, and celery forms the base of many traditional dishes, though this recipe focuses more on the garlic and onion components for a streamlined approach. The combination of cream with spice isn't traditionally Cajun, but represents the evolution of cuisine that makes American food so dynamic and exciting.
