25-Minute Creamy Cajun Sausage Pasta
This creamy Cajun sausage pasta comes together in one pan and 25 minutes, with smoky andouille sausage and a quick spiced cream sauce that coats every bite of pasta. It’s the kind of dinner that feels a lot more special than the effort it takes.
The sauce is rich with just enough heat to keep you going back for another bite, and the whole dish uses ingredients you can easily keep on hand. Once you make it, it’ll land straight in your regular weeknight rotation.
Why This Pasta Stays in My Weeknight Rotation
The sauce does the heavy lifting here. Heavy cream and Parmesan turn into something silky in the same pan you brown the sausage in, so you save on dishes without losing any depth of flavor.
The andouille sausage brings a smoky, gently spicy backbone that a jarred sauce just can’t match, and the pasta cooks right in the liquid so it absorbs every bit of that Cajun seasoning. It’s creamy but not heavy, with a little tingle on the finish that makes the richness feel balanced instead of too much.
Ingredients
- 12 oz andouille sausage, sliced into ½-inch rounds: any fully cooked smoked sausage works here
- 2 tbsp olive oil
- 1 small yellow onion, diced
- 1 red bell pepper, thinly sliced
- 3 cloves garlic, minced
- 2 tbsp Cajun seasoning: use your favorite blend; salt content varies
- 2 cups chicken broth
- 1 cup heavy cream
- 8 oz penne pasta
- ½ cup grated Parmesan cheese
- Salt and black pepper, to taste
Variations / Substitutions
- Smoked turkey or chicken sausage: a leaner option that still has good flavor, just reduce the initial browning time slightly.
- Half-and-half instead of heavy cream: the sauce will be a bit thinner; you can let it bubble a minute longer to thicken.
- Add a handful of baby spinach: stir it in right before serving so it wilts gently from the residual heat.
- Swap the pasta shape: rotini, rigatoni, or shells all grab the sauce nicely; just check for doneness a minute early.
- Make it dairy-free: use full-fat canned coconut milk and omit the Parmesan; the sauce will be slightly sweeter and still creamy.

How to Make Creamy Cajun Sausage Pasta
Step 1: Brown the Sausage
Set a large skillet or Dutch oven over medium-high heat and add the 2 tbsp olive oil. Once the oil shimmers, add the sliced sausage in a single layer. Cook for about 5 minutes, turning the pieces once or twice, until both sides are deeply browned with darker edges. Transfer the sausage to a plate and set it aside.
You’ll see little browned bits left in the pan—don’t wipe them out. Those bits will flavor the entire sauce.
Step 2: Sauté the Veggies and Spices
Lower the heat to medium and add the diced onion and sliced bell pepper to the same pan. Cook, stirring occasionally, until softened and the onion turns translucent, about 4 minutes. Stir in the minced garlic and the 2 tbsp Cajun seasoning. Keep it moving for 30 seconds until the garlic is fragrant and the spices bloom.
This quick step wakes up the seasoning and makes the whole kitchen smell incredible.
Step 3: Simmer the Pasta in the Cream Sauce
Pour in the 2 cups chicken broth and 1 cup heavy cream, scraping the bottom of the pan with a wooden spoon to lift all the browned bits. Bring the liquid to a gentle simmer, then stir in the 8 oz penne pasta. Cover the pan, reduce the heat to medium-low, and cook for 12 minutes. Stir every few minutes so nothing sticks, and check a piece of pasta near the end—it should be tender and the sauce will have thickened enough to coat the back of a spoon.
The pasta absorbs the liquid as it cooks, so you end up with a creamy, clingy sauce without needing a separate pot.
Step 4: Toss It All Together and Serve
Remove the pan from the heat. Add the browned sausage back to the pan along with the ½ cup grated Parmesan. Toss everything together until the sausage is coated in sauce and the cheese melts through. Taste and season with salt and black pepper as needed. Spoon the pasta into bowls right away while it’s hot and the sauce is still glossy.
A Few Notes Before You Start
- Cajun seasoning blends vary a lot in salt and heat. If it’s your first time using a new brand, start with 1½ tbsp and add more after tasting the finished dish.
- Freshly grated Parmesan melts much more smoothly than pre-shredded, and it matters here because the cheese is what pulls the sauce together.
- If the pasta soaks up the liquid before it’s fully tender, add a splash of warm broth or water and continue cooking a minute or two.
- Letting the sausage get a real brown crust in step one makes a big difference. Don’t rush that part; the caramelized edges bring a lot of the savory depth.
Storing Leftovers
- Refrigerate: Keep leftovers in an airtight container for up to 3 days. The pasta will soak up more sauce as it sits, so it will be thicker when cold, which is totally normal.
- Reheating: Warm it gently in a skillet over medium-low heat with a small splash of milk or broth to loosen the sauce back up. Stir frequently so it heats evenly and the cream doesn’t separate.
What to Serve with Creamy Cajun Sausage Pasta
A simple green salad with a sharp lemon vinaigrette cuts through the richness and gives you a little acidity to balance the creamy sauce. If you want something to swipe through the last of the sauce, warm crusty bread or garlic toast is always welcome.
Frequently Asked Questions
Can I use a different type of pasta?
Yes. Any short shape like rotini, rigatoni, or farfalle works. Just keep an eye on the cooking time and start checking for doneness a minute or two earlier than the package suggests since the pasta cooks in a smaller amount of liquid.
Can I make this dairy-free?
Yes. Swap the heavy cream for one can of full-fat coconut milk and skip the Parmesan. The sauce will be a little sweeter, but the Cajun seasoning and sausage still carry the dish.
How do I make it spicier?
Add a pinch of cayenne pepper along with the Cajun seasoning, or use a hot Italian sausage instead of andouille. You can also finish with a few dashes of your favorite hot sauce.
Can I add vegetables to the dish?
Definitely. A large handful of baby spinach stirred in at the end wilts quickly, or throw in some halved cherry tomatoes right before serving for a burst of freshness.
