This creamy Cajun shrimp pasta with sausage combines two proteins, a velvety parmesan cream sauce, and just enough heat to keep things interesting.

Whether you are searching for easy Cajun pasta recipes with shrimp and sausage for a weeknight dinner, or you want a showstopper for date night in, this dish checks every box. It is rich without being heavy, spicy without being overwhelming, and endlessly adaptable to what you have on hand.
Before we get cooking, the right tools and ingredients make a real difference here. A heavy bottomed skillet helps the sausage develop a deep, even sear, and a good quality Cajun seasoning blend keeps the flavor consistent every single time. These are the products that genuinely help this recipe shine:
The Secret to Perfect Cajun Shrimp and Sausage Pasta
The key to a truly great Cajun shrimp and sausage pasta lies in layering flavor at every step instead of dumping everything into one pot at once. Searing the sausage first renders out its smoky fat, which becomes the base for cooking the shrimp and vegetables. That fond, the browned bits left in the pan, is pure flavor gold.
Andouille sausage is traditional and brings a deep smokiness, but kielbasa or smoked turkey sausage are both excellent substitutes if that is what your grocery store carries. For the shrimp, look for large or jumbo shrimp so they hold up to the sauce without overcooking.
Chef's Tip: Cook your shrimp just until they turn pink and curl into a loose C shape. An overcooked shrimp curls into a tight O and turns tough, so pull them from the heat a few seconds early since they will continue cooking slightly off the heat.
Building That Creamy Cajun Sauce
What sets this creamy sausage and shrimp pasta apart from a basic tomato based Cajun dish is the luxurious cream sauce. Sauteed onion and bell pepper form the aromatic base, often called the Cajun holy trinity when celery joins the mix. A splash of chicken broth loosens things up and helps lift any stuck-on flavor from the bottom of the pan before the cream goes in.
Freshly grated parmesan melts into the warm cream, thickening the sauce naturally and adding a salty, nutty backbone that balances the heat from the Cajun seasoning and red pepper flakes. Stirring in starchy reserved pasta water at the end is the easy trick that makes the sauce cling to every strand of linguine instead of pooling at the bottom of the bowl.

Creamy Cajun Shrimp Pasta with Sausage
Smoky andouille sausage and juicy Cajun shrimp swim in a rich, spicy cream sauce tossed with linguine, ready in just 35 minutes for a restaurant-quality dinner at home.
Ingredients
- 12 oz linguine, or fettuccine
- 1 lb large shrimp, peeled and deveined, tails removed
- 12 oz andouille sausage, sliced into rounds
- 2 tbsp cajun seasoning, divided, plus more to taste
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 1/2 cup yellow onion, finely diced
- 1/2 cup red bell pepper, diced
- 4 cloves garlic, minced
- 1/2 cup chicken broth, low sodium
- 1 1/2 cups heavy cream
- 3/4 cup parmesan cheese, freshly grated
- 1/2 tsp smoked paprika
- 1/4 tsp red pepper flakes, optional, for extra heat
- 2 tbsp fresh parsley, chopped, for garnish
- 1 tsp kosher salt, to taste
- 1/2 tsp black pepper, freshly cracked
Instruction
Bring a large pot of salted water to a boil and cook the linguine according to package directions until al dente. Drain, reserving 1 cup of pasta water, and set aside.
Pat the shrimp dry and toss with 1 tablespoon of Cajun seasoning. Set aside to marinate while you prep the rest of the ingredients.
Heat olive oil in a large, deep skillet or Dutch oven over medium-high heat. Add the sliced andouille sausage and cook for 3 to 4 minutes until browned and slightly crisped. Remove with a slotted spoon and set aside.
In the same skillet, melt 1 tablespoon of butter. Add the seasoned shrimp in a single layer and cook for 1 to 2 minutes per side until pink and just opaque. Remove and set aside with the sausage.
Lower the heat to medium and melt the remaining butter. Add the onion and bell pepper and cook for 3 to 4 minutes until softened.
Stir in the garlic and cook for 30 seconds until fragrant, being careful not to let it burn.
Pour in the chicken broth and simmer for 2 minutes, scraping up any browned bits from the bottom of the pan.
Reduce heat to low and stir in the heavy cream, remaining Cajun seasoning, smoked paprika, and red pepper flakes. Simmer gently for 4 to 5 minutes until slightly thickened.
Whisk in the parmesan cheese until melted and smooth. Season with salt and black pepper to taste.
Return the sausage and shrimp to the skillet along with the cooked linguine. Toss everything together, adding splashes of reserved pasta water as needed to loosen the sauce.
Garnish with chopped parsley and extra parmesan, then serve immediately while hot.

Notes
Serving, Storing, and Mixing Things Up
This dish is hearty enough to stand entirely on its own, but a slice of crusty garlic bread or a simple green salad with vinaigrette rounds out the meal nicely. A glass of crisp white wine, like a Sauvignon Blanc, plays really well against the richness of the cream sauce.
If you are meal prepping, keep the components separate until you are ready to eat. Store the cooked pasta, the sauce, and the shrimp and sausage in separate containers if possible, then combine and reheat gently together. This keeps the shrimp from turning rubbery and the pasta from soaking up all the sauce overnight.
A few easy variations to keep in your back pocket:
- Lighten it up: Swap half the heavy cream for whole milk or half and half.
- Extra veggies: Stir in baby spinach or halved cherry tomatoes during the last few minutes of cooking.
- Gluten free: Use your favorite gluten free linguine or fettuccine, the sauce itself is naturally gluten free.
- Extra smoky heat: Add a touch more smoked paprika and a pinch more red pepper flakes.
Chef's Tip: Always taste your Cajun seasoning blend before doubling up, some brands are significantly saltier or spicier than others, so adjust gradually rather than dumping in the full amount at once.
However you serve it, this easy creamy Cajun shrimp pasta with sausage is destined to become one of those recipes you find yourself making on repeat, the kind friends ask for by name when they come over for dinner.
