Whether you are searching for spicy shrimp and sausage pasta, a new Cajun pasta recipe, or just a dependable one pot Cajun shrimp and sausage pasta for a busy Tuesday, this recipe is going to become a permanent fixture in your rotation.
Why This Recipe Works So Well
A lot of shrimp and sausage pasta recipes end up with either overcooked shrimp, a watery sauce, or flavors that feel muddy rather than layered. Here is how this recipe avoids all of that:
- Sear separately, finish together. Cooking the sausage and shrimp in stages before adding them back to the sauce at the very end means every component gets proper browning without overcooking.
- Cook the pasta slightly underdone. Pulling the penne two minutes early and finishing it in the sauce allows it to absorb the Cajun cream and reach the perfect texture without going mushy.
- Bloom the spices. Toasting the Cajun seasoning and smoked paprika in the butter for 30 seconds before adding liquid unlocks a deeper, more complex flavor than simply stirring them in.
- Deglaze with broth. All those browned bits stuck to the pan after searing the sausage? Pure flavor. The chicken broth lifts them right into the sauce where they belong.
Chef's Tip: The single biggest mistake people make with shrimp is overcooking. Cook them just until they curl into a loose C shape and turn pink, then pull them off the heat immediately. They will continue cooking slightly from residual heat when added back to the pasta.
Choosing the Right Ingredients
This is a recipe where the quality of a few key ingredients really does show up in the final bowl. Using a good smoked andouille sausage rather than a generic link makes a noticeable difference in depth and smokiness. For the shrimp, fresh or frozen both work well, but make sure they are fully thawed, peeled, deveined, and patted very dry before they hit the pan. Moisture is the enemy of a good sear.
The right kitchen tools make this come together even more smoothly. A wide, deep 12-inch skillet or a Dutch oven gives you enough surface area to sear the sausage properly and enough depth to toss the pasta without sending noodles flying. Here are a few tools and pantry staples that genuinely make this Cajun pasta recipe easier to pull off:
Customize It Your Way
One of the best things about this seafood pasta with shrimp and sausage is how adaptable it is. Here are a few variations worth trying:
- Lighter version: Swap the heavy cream for half-and-half and reduce the sausage to 8 ounces. The sauce will be thinner but still flavorful.
- Extra smoky: Add a teaspoon of liquid smoke or use smoked Gouda in place of half the Parmesan.
- More vegetables: Zucchini, cherry tomatoes, or corn all fit the Cajun flavor profile and add bulk without changing the core recipe.
- Gluten-free: Use your favorite gluten-free pasta and a gluten-free Cajun seasoning blend. Check the sausage label as well.
A Note on Cajun Seasoning
Store-bought Cajun seasoning blends vary wildly in saltiness and heat level. Brands like Tony Chachere's, Slap Ya Mama, and Zatarain's are all solid choices, but if yours is particularly salty, hold back on adding extra salt until you have tasted the finished sauce.
What to Serve With This
This pasta is filling on its own, but a few simple sides turn it into a proper spread:
- Crusty garlic bread for sopping up every last drop of that Cajun cream sauce
- A simple green salad dressed with lemon vinaigrette to cut through the richness
- Roasted asparagus or broccolini for a bit of green on the plate
For drinks, a cold lager or a crisp white wine like Pinot Grigio or Sauvignon Blanc pairs beautifully with the spice and creaminess.

Cajun Shrimp and Sausage Pasta
This bold and creamy Cajun Shrimp and Sausage Pasta comes together in one pot with smoky andouille, juicy shrimp, and a spicy Cajun cream sauce that clings to every noodle. Ready in 35 minutes and packed with flavor.
Ingredients
- 12 oz penne pasta, or rigatoni
- 1 lb large shrimp, peeled and deveined, tails off
- 12 oz andouille sausage, sliced into rounds
- 2 tbsp olive oil, divided
- 2 tbsp unsalted butter
- 5 garlic cloves, minced
- 1 yellow onion, diced
- 1 red bell pepper, diced
- 1 green bell pepper, diced
- 1 1/2 cups heavy cream
- 1 cup chicken broth, low sodium
- 14 oz diced tomatoes, one can, drained
- 2 tbsp Cajun seasoning, store-bought or homemade, divided
- 1 tsp smoked paprika
- 1/2 tsp crushed red pepper flakes, optional, for extra heat
- 1/2 cup Parmesan cheese, freshly grated, plus more for serving
- 3 tbsp fresh parsley, chopped, for garnish
- 1 tsp salt and black pepper, to taste
Instruction
Bring a large pot of salted water to a boil. Cook the pasta 2 minutes shy of the package directions (it will finish cooking in the sauce). Reserve 0.5 cup of pasta water before draining. Set pasta aside.
Pat the shrimp dry with paper towels. Toss with 1 tablespoon of Cajun seasoning and a pinch of salt until evenly coated.
Heat 1 tablespoon of olive oil in a large deep skillet or Dutch oven over medium-high heat. Add the andouille sausage slices and cook for 3 to 4 minutes, flipping once, until browned on both sides. Remove and set aside.
In the same skillet, add the remaining tablespoon of olive oil. Add the seasoned shrimp in a single layer and cook for 1 to 2 minutes per side until pink and just cooked through. Do not overcook. Remove and set aside with the sausage.
Reduce heat to medium. Add the butter to the skillet. Once melted, add the diced onion and bell peppers. Cook for 4 to 5 minutes, stirring occasionally, until softened. Add the minced garlic and cook for 1 more minute until fragrant.
Stir in the remaining 1 tablespoon of Cajun seasoning, smoked paprika, and red pepper flakes. Cook for 30 seconds to bloom the spices.
Pour in the chicken broth and use a wooden spoon to scrape up any browned bits from the bottom of the pan. Add the drained diced tomatoes and stir to combine.
Pour in the heavy cream and bring the sauce to a gentle simmer. Cook for 4 to 5 minutes, stirring occasionally, until the sauce begins to thicken slightly.
Add the drained pasta to the sauce and toss to coat. If the sauce is too thick, add a splash of the reserved pasta water to loosen it. Stir in the grated Parmesan until melted and smooth.
Return the cooked sausage and shrimp to the skillet. Gently fold everything together and heat for 1 to 2 minutes until warmed through. Taste and adjust seasoning with salt and black pepper.
Serve immediately, garnished with fresh chopped parsley and extra Parmesan cheese.

Notes
Storing and Reheating Leftovers
Leftovers keep in an airtight container in the fridge for up to 3 days. When it comes time to reheat, skip the microwave if you can. Instead, warm the pasta in a skillet over medium-low heat with a splash of chicken broth or cream to bring the sauce back to life. Stir gently and give the shrimp as little time over heat as possible.
This dish does not freeze well. The cream sauce tends to separate and the shrimp become rubbery after freezing and thawing, so plan to enjoy it fresh within a few days.
Make It Ahead: You can slice the sausage, chop the vegetables, and mix your seasoning up to 24 hours in advance. Store everything separately in the fridge so that when it is time to cook, you are just 35 minutes away from dinner on the table.
Whether this is your first time making a shrimp and sausage pasta recipe or your tenth, this version earns its place as the definitive go-to. Bold spice, creamy sauce, smoky sausage, juicy shrimp. It is everything a Cajun pasta recipe should be.
