Tip: save now, make later.
When sausage rounds hit a hot Dutch oven, they sizzle and leave browned bits behind. That’s where this Cajun Shrimp and Sausage Pasta starts building its deep, savory flavor before the cream even goes in. I like the contrast of tender shrimp with the firmer, smoky sausage, all tangled through wide fettuccine.
The sauce is rich, but it shouldn’t feel heavy or sit in a puddle at the bottom of the bowl. The finished pasta has a creamy coating, a little Cajun warmth, and enough bite from the sausage and shrimp to make each forkful feel complete. It’s a generous skillet meal that serves six, and it’s at its best just after the pasta gets tossed through the sauce.

Kitchen Note
I keep the drained fettuccine and reserved cooking water beside the stove before the cream goes in. The sauce only needs a few minutes at a gentle simmer, and having everything within reach lets me move straight into the final toss before it thickens on its own.
Save this Cajun Shrimp and Sausage Pasta for a creamy, Cajun-spiced dinner with browned andouille and tender shrimp.
Why This Cream Sauce Needs Pasta Water, Not More Cream
When a cream sauce seems too loose, adding more cream isn’t always the fix. In this pasta, the reserved cooking water brings starch from the fettuccine into the sauce. That starch helps the cream, Parmesan, and liquid cling together around the noodles instead of separating into a slick sauce and a pile of pasta.
The water also gives you a way to bring the finished dish together without making it heavier. The sauce simmers until it’s only slightly thickened, then the pasta, cheese, shrimp, and sausage go back into the Dutch oven with the reserved water. Tossing everything over low heat gives the fettuccine time to pick up the sauce while the Parmesan melts into it. Don’t expect a thick coating before the pasta goes in; the final toss is what brings the texture into balance.
That small reserve is easy to forget once the noodles are draining, so set it aside before you pour off the pot. If you skip it, the dish can still taste rich, but the sauce won’t cling in quite the same way.
What Andouille, Shrimp, and Parmesan Each Bring to This Cajun Pasta

- Fettuccine — Its wide ribbons hold onto the creamy sauce. Linguine works if that’s what you have, though the narrower noodles give you a slightly different bite; cook it al dente according to the package directions.
- Andouille sausage — Andouille brings smoke and seasoning that plain sausage won’t quite match. A smoked kielbasa can stand in, but the pasta will lose some of its characteristic peppery Cajun edge. An everyday brand works well here; the browning adds plenty of flavor.
- Large shrimp — Larger shrimp stay distinct beside the sausage and are less likely to disappear in the pasta. Fresh or frozen shrimp both work; if using frozen, thaw them fully and drain them before seasoning so excess water doesn’t interfere with cooking.
- Cajun seasoning — This blend supplies the dish’s defining heat and spice. The salt and heat level vary between brands, so choose one you already like; a basic store-brand blend is fine.
- Garlic — Freshly minced cloves give the sauce a clear, savory note. Jarred minced garlic can work in a pinch, but fresh garlic has a brighter flavor and cooks quickly into the broth and cream.
- Chicken broth and heavy cream — Low-sodium broth gives the sauce a savory base without adding as much salt as regular broth, while heavy cream supplies its body. Half-and-half makes a thinner sauce, so heavy cream is the better choice for the intended texture.
- Freshly grated Parmesan — Parmesan melts into the sauce and adds a salty, nutty finish. Grate it fresh from a wedge for the smoothest result; pre-grated cheese can stay grainy instead of blending in as evenly.
- Olive oil — A basic olive oil is all you need for browning the sausage. Save a more expensive bottle for a dish where its flavor will stand out uncooked.
From Browned Andouille to a Creamy, Coated Fettuccine
Cook the Fettuccine and Save the Starchy Water
Bring a large pot of water to a boil and stir in the kosher salt. Add the fettuccine and cook it al dente according to the package directions. Before draining, reserve the pasta cooking water; once it’s poured away, there’s no getting that starchy liquid back. Drain the pasta and keep it nearby for the finish.
Brown the Sausage, Then Cook the Shrimp
Heat the olive oil in a 6-quart Dutch oven over medium-high heat. Add the sliced sausage and cook for 4 to 5 minutes, until the rounds are browned, then transfer them to a plate. Toss the shrimp with 1 teaspoon of the Cajun seasoning and cook them in batches in the same Dutch oven. Give them 1 to 2 minutes per side, until opaque and 145°F, then move them to the plate with the sausage.
Simmer the Garlic, Seasoning, Broth, and Cream
Add the minced garlic and remaining Cajun seasoning to the Dutch oven over medium heat. Stir constantly for 30 seconds so the garlic cooks without scorching. Pour in the chicken broth and heavy cream, then bring the mixture to a gentle simmer. Cook for 4 to 5 minutes, until the sauce is slightly thickened.
Toss Everything Until the Parmesan Melts
Add the drained fettuccine, browned sausage, shrimp, freshly grated Parmesan, and reserved pasta water to the Dutch oven. Toss over low heat for 1 to 2 minutes, moving the pasta through the sauce so it gets coated. The cheese should melt into the cream, and the sauce should cling to the noodles rather than collect in a thin layer at the bottom. Take the pan off the heat once everything is combined.
Three Ways to Adapt This Cajun Shrimp and Sausage Pasta
Make It Gluten-Free
Use gluten-free fettuccine in place of the regular pasta and cook it to al dente according to its package directions. The creamy Cajun sauce still works, though some gluten-free noodles soften more quickly once tossed, so serve the pasta soon after finishing it.
Let the Shrimp Take Center Stage
Leave out the andouille for a shrimp-forward version. The sauce will taste less smoky and savory, while the Cajun seasoning still gives the cream a spiced finish.
Make It Sausage-Forward
Skip the shrimp and keep the andouille for a simpler, smoky pasta. You’ll have fewer delicate pieces to handle, and the sausage becomes the main savory bite in each forkful.
Storage and Reheating
- Refrigerator: Store leftovers in a sealed container within 2 hours and use within 3 to 4 days. The pasta absorbs some sauce as it sits.
- Freezer: Freezing isn’t recommended; the cream sauce may separate and the fettuccine can turn soft after thawing.
- Reheating: Warm leftovers gently in a skillet over low heat with a small splash of chicken broth, stirring until they reach 165°F. High heat can make the shrimp rubbery and the sauce oily.
