The Cajun Pasta That Belongs in Your Regular Rotation
There are pasta dishes you make once on a whim, and then there are the ones that quietly become a household staple. This creamy Cajun shrimp pasta with sausage falls firmly into the second category. It hits every note you want from a satisfying dinner: smoky andouille sausage, plump seasoned shrimp, and a rich, spicy cream sauce clinging to every noodle. It is bold without being overwhelming, and it comes together in one skillet in under 40 minutes.
Whether you're searching for an easy creamy Cajun shrimp pasta with sausage for a busy Tuesday night or something impressive enough to serve guests on the weekend, this recipe delivers every single time.
Why This Recipe Works
A lot of Cajun pasta recipes shrimp and sausage combos tend to fall flat in one of two ways: either the sauce is too thin and slides off the pasta, or the shrimp overcooks into little rubber erasers. This recipe solves both problems.
Here's what makes it special:
- Sear the sausage first. Browning the andouille creates deep, caramelized fond on the bottom of the pan. That flavorful layer becomes the backbone of the entire sauce.
- Season the shrimp separately. Tossing shrimp directly in Cajun seasoning before cooking means every bite is seasoned from the inside out, not just coated in sauce.
- Add shrimp last. Shrimp only need 2 to 3 minutes in a simmering sauce. Going longer makes them tough. Pull them the moment they curl and turn pink.
- Reserve pasta water. A splash of starchy pasta water at the end helps bind the sauce to the noodles, giving you that silky restaurant-quality finish.
Chef's Tip: Freshly grated Parmesan melts far more smoothly into the cream sauce than the pre-shredded kind. Pre-shredded cheese contains anti-caking agents that can make your sauce grainy. Take the extra minute to grate it yourself.
Choosing Your Ingredients
For a dish like this creamy sausage and shrimp pasta, ingredient quality genuinely moves the needle. The right Cajun seasoning determines whether your sauce tastes layered and complex or just hot. Using a good smoked andouille, rather than a generic beef sausage, gives you that authentic bayou depth.
Using the right tools in the kitchen can also make a real difference here, from a wide, heavy skillet that holds heat evenly to a quality box grater for the Parmesan.
Andouille sausage is the traditional choice for Cajun shrimp and sausage pasta, and it's worth seeking out. Its smoky, garlicky flavor is distinct. If your grocery store doesn't carry it, smoked kielbasa is the next best option.
For the shrimp, go with large or jumbo shrimp (21 to 30 count per pound) that are already peeled and deveined. Smaller shrimp can overcook almost instantly in the hot sauce. Frozen shrimp work just as well as fresh here; just make sure they're fully thawed and patted completely dry before seasoning.
The heavy cream is non-negotiable for that luscious, coating sauce. Half-and-half will give you a thinner result. If you want to lighten things up, full-fat coconut cream is a surprisingly good dairy-free stand-in that plays well with the Cajun spices.
How to Nail the Cajun Seasoning
Your Cajun seasoning does most of the heavy lifting in this recipe. A good blend typically includes paprika, garlic powder, onion powder, oregano, thyme, cayenne, and black pepper. Store-bought blends vary wildly in salt content, so taste your sauce before adding any extra salt.
If you prefer to make your own, combine: 2 tsp smoked paprika, 1 tsp garlic powder, 1 tsp onion powder, 0.5 tsp cayenne, 0.5 tsp dried oregano, 0.5 tsp dried thyme, 0.5 tsp black pepper, and 0.5 tsp salt. This gives you enough for this recipe with a bit left over to season your next batch of Cajun seasoned shrimp and sausage linguine.
Spice Note: This recipe as written is moderately spicy, a warm heat that builds slowly. If you're cooking for kids or spice-sensitive guests, reduce the Cajun seasoning to 1 tablespoon total and offer hot sauce on the side for those who want more fire.
What Pasta Shape to Use
Penne is the classic call for a dish like this Cajun shrimp and sausage pasta, and for good reason. The ridged tubes scoop up the creamy sauce and hold the bits of sausage and shrimp in every forkful. But this sauce is forgiving and works beautifully with:
- Linguine for a more elegant, twirl-able presentation
- Fettuccine for extra surface area to coat
- Rigatoni for hearty, chunky bites
- Cavatappi (corkscrew pasta) for serious sauce-grabbing power
Whatever shape you choose, cook it just to al dente. It will finish cooking slightly in the hot sauce when you toss everything together.

Creamy Cajun Shrimp Pasta with Sausage
This creamy Cajun shrimp pasta with sausage is bold, smoky, and ready in under 40 minutes. Juicy shrimp and andouille sausage tossed in a spicy, velvety sauce make this the ultimate weeknight comfort meal.
Ingredients
- 12 oz penne or linguine pasta, or fettuccine
- 1 lb large shrimp, peeled and deveined, tails off
- 12 oz andouille sausage, sliced into coins
- 2 tbsp Cajun seasoning, divided, store-bought or homemade
- 2 tbsp olive oil, extra virgin
- 2 tbsp unsalted butter
- 1 yellow onion, medium, diced
- 1 red bell pepper, diced
- 4 garlic cloves, minced
- 1/2 cup chicken broth, low sodium
- 1 1/2 cups heavy cream
- 14 oz diced tomatoes, canned, drained
- 1/2 cup Parmesan cheese, freshly grated, plus more for serving
- 1 tsp salt and black pepper, to taste
- 2 tbsp fresh parsley, chopped, for garnish
Instruction
Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente. Reserve 0.5 cup of pasta water before draining, then set the pasta aside.
Pat the shrimp dry with paper towels and toss them with 1 tablespoon of Cajun seasoning. Set aside.
Heat 1 tablespoon of olive oil in a large deep skillet or Dutch oven over medium-high heat. Add the sliced andouille sausage and sear for 2 to 3 minutes per side until browned. Remove the sausage and set it aside.
In the same skillet, add the remaining tablespoon of olive oil and the butter over medium heat. Add the diced onion and red bell pepper. Saute for 4 to 5 minutes until softened.
Add the minced garlic and remaining 1 tablespoon of Cajun seasoning. Cook for 1 minute, stirring constantly, until fragrant.
Pour in the chicken broth and stir, scraping up any browned bits from the bottom of the pan. Let it reduce for 1 to 2 minutes.
Add the heavy cream and drained diced tomatoes. Stir to combine and bring to a gentle simmer. Cook for 4 to 5 minutes until the sauce begins to thicken.
Add the seasoned shrimp to the simmering sauce. Cook for 2 to 3 minutes, just until the shrimp curl and turn pink. Do not overcook.
Return the sausage to the skillet. Add the drained pasta and toss everything together, adding a splash of the reserved pasta water if the sauce needs loosening.
Remove from heat and stir in the freshly grated Parmesan. Taste and adjust salt and pepper as needed.
Serve immediately, garnished with fresh parsley and additional Parmesan.
Equipment
- Large pot for boiling pasta
- Large deep skillet or Dutch oven (12-inch recommended)
- Wooden spoon or silicone spatula
- Colander
- Chef's knife and cutting board
- Measuring cups and spoons
- Box grater or microplane for Parmesan
Notes
Serving, Storing, and Variations
Serving suggestions: This pasta is a full meal on its own, but a simple green salad and crusty garlic bread alongside make it feel like a proper occasion. A glass of chilled Pinot Grigio or a light lager pairs really well with the spice.
Variations worth trying:
- Cajun shrimp, chicken, and sausage pasta: Add 1 boneless chicken thigh per person, sliced thin and seared before the sausage. This turns it into a full surf-and-turf skillet.
- Vegetable additions: Sliced mushrooms, baby spinach, or zucchini can be added with the onions and peppers for extra bulk and nutrition.
- Lighter version: Swap heavy cream for half-and-half and use chicken sausage instead of andouille. The sauce will be thinner but still delicious.
Storing leftovers: Transfer cooled pasta to an airtight container and refrigerate for up to 3 days. Reheat gently in a skillet over low heat with a splash of cream or broth to revive the sauce. The shrimp are best eaten within 24 hours for ideal texture.
This is the kind of recipe that gets requested by name. Once your household tries it, creamy Cajun shrimp and sausage pasta earns its spot in the permanent dinner lineup.
