Anyone who knows me knows I love pasta. I’m not talking about a polite, once-a-week kind of love.
When I was about ten, one of the first cookbooks I ever bought for myself was called 365 Days: I Want to Eat Pasta. It was a pasta book; I bought it with my own money, and I read it like a novel. That’s the kind of person I am.
I love the classics — fresh basil pesto, a proper carbonara — but my favorite pasta is the kind that borrows from a tradition and then runs with it.
That’s what this Cajun sausage pasta is: a one-pot penne dish with heat from the andouille, creamy sauce, and enough savoriness that you’ll want a second bowl before the first is gone.
It’s not traditional Italian, and it’s not trying to be. It’s the pasta I make when I want something with a little fire.
The recipe solves the specific problem with most creamy Cajun pasta recipes: they lean on a full cup or more of heavy cream, and the sauce ends up rich but one-note.
This version uses fire-roasted crushed tomatoes and a little cream cheese instead, giving you a velvety orange-red sauce with tomato tang and deep Cajun spice, without the heaviness. Add the andouille first, sear until the edges are crispy, and let those browned bits become the base for everything that follows.
I make this in my kitchen with a cast iron skillet and standard penne, and the most important detail is stirring the pasta every couple of minutes while it simmers.
One-pot pasta wants to stick to the bottom of the pan, and scraping the bottom every two minutes with a wooden spoon keeps the penne separate and the sauce smooth instead of scorched.
It’s the least exciting instruction in the recipe and the one that makes the difference.
Why This Recipe Works
Searing the andouille first and leaving the rendered fat in the pan is what builds the flavor. Andouille is smoked and spicy, and when it hits a hot skillet, the fat renders out and the edges crisp. That fat is the cooking medium for the peppers and the base for the sauce — it carries the Cajun spice and the tomato into every bite. If you pour it off, you’re pouring off the flavor.
Fire-roasted crushed tomatoes give you the sauce body without heavy cream. Most one-pot Cajun pasta recipes use a cup or more of cream. The crushed tomatoes do the thickening and bring acidity that cuts through the richness of the sausage and cream cheese. The result tastes like a Cajun tomato cream sauce rather than an Alfredo with stirred-in spice.
Adding cream cheese at the end makes the sauce velvety instead of watery. Cream cheese melts into the tomato-pasta liquid and emulsifies into a glossy sauce that clings to the penne. Cubing it and letting it soften before adding it keeps it from clumping.
Simmering the pasta uncovered and stirring every two minutes is what makes one-pot work. Covered one-pot pasta steams, and the pasta can clump. Uncovered, the liquid reduces as the pasta absorbs it, and stirring keeps the starch from gluing the penne to the bottom. Nine to eleven minutes is the window — check at nine and pull it when it’s al dente.
The Parmesan goes in off the heat, at the very end. Parmesan is prone to seizing and turning stringy when it hits a hard boil. Turning the heat off before you add it means it melts smoothly into the sauce instead of clumping. The same goes for the parsley — it stays green and fresh when it’s stirred in off the heat.
A pinch of red pepper flakes at the table is optional but worth having. Cajun seasoning blends vary a lot in heat, and the andouille is already spicy. Serving red pepper flakes on the side lets people adjust their own bowl without making the whole pot too hot for anyone.
Ingredients That Matter
Most of this list is flexible. Three ingredients are easy to get wrong, so those are the ones worth explaining.
Smoked andouille sausage. This is the flavor backbone, and it’s worth seeking out over a generic smoked sausage. Andouille is coarser, smokier, and more heavily seasoned, and it holds up against the sauce’s Cajun spice. Kielbasa works but is milder and sweeter. Slice it into ¼-inch medallions so the edges crisp rather than the centers drying out.
Low-sodium Cajun seasoning. Cajun blends vary wildly in salt content, and a full 2 tablespoons of a salty blend can push the whole pot over the edge. Start with 1½ tablespoons, taste the sauce after the tomatoes go in, and add the rest if it needs it. If your blend is salt-free, you’ll want to add salt separately.
Light cream cheese (Neufchâtel), cubed and softened. This is the creamy element, and it needs to be at room temperature and cut into small cubes so it melts evenly. Cold cream cheese in one block will leave lumps no matter how hard you whisk. Full-fat cream cheese works but pushes the fat number up; Neufchâtel is slightly tangier and lighter.
How to Make It
Step 1: Crisp the sausage.
Heat a large cast iron skillet or heavy braiser over medium-high heat. Add 13 oz of sliced andouille in a single layer and sear undisturbed for 2 to 3 minutes per side, until the edges are dark golden-brown and crispy. Transfer to a plate, leaving the rendered fat in the skillet.
Step 2: Sauté the peppers and garlic.
Reduce the heat to medium. Add the sliced red and green bell peppers to the skillet and sauté for 3 to 4 minutes, until crisp-tender and bright in color. Add 3 minced garlic cloves and cook for 30 seconds, until fragrant.
Step 3: Build the sauce and add the pasta.
Add 12 oz uncooked penne, 1 cup crushed fire-roasted tomatoes, 3 cups low-sodium chicken broth, and 1½ to 2 tablespoons Cajun seasoning. Stir thoroughly to submerge the penne. Bring to a boil over medium-high heat.
Step 4: Simmer uncovered, stirring every two minutes.
Reduce the heat to medium and leave the skillet uncovered. Simmer for 9 to 11 minutes, stirring every 2 minutes and scraping the bottom of the pan, until the penne is al dente and the liquid has reduced into a thick tomato base. If the pan looks dry before the pasta is tender, add a splash of broth.
Step 5: Emulsify the creamy base.
Turn the heat to low. Stir in ½ cup of milk (or extra broth) and the cubed softened cream cheese. Whisk gently for 1 to 2 minutes as the cream cheese melts, until the liquid turns into a rich, velvety orange-red sauce that clings to the penne.
Step 6: Combine and finish.
Return the crispy sausage and any juices on the plate to the skillet. Toss for 1 minute until heated through. Remove from the heat and stir in ¼ cup of freshly grated Parmesan.
Step 7: Garnish and serve.
Sprinkle with fresh chopped parsley, extra Parmesan, and red pepper flakes for heat. Serve straight from the skillet.
Tips and Troubleshooting
The pasta stuck to the bottom of the pan. You didn’t stir often enough, or the heat was too high. Stir every two minutes with a wooden spoon, scraping the bottom, and keep the heat at medium.
The sauce is too thick or dry. The pasta absorbed more liquid than expected, or the pan was too wide. Add a splash of broth or milk and stir until the sauce loosens. A wider pan evaporates faster, so a deeper skillet helps.
The sauce is watery. The pasta wasn’t simmered long enough uncovered, or the tomatoes were very juicy. Simmer for the full 9 to 11 minutes and let the sauce reduce before the cream cheese goes in.
The cream cheese left lumps. It was cold or added in one block. Cube it, let it soften at room temperature, and whisk it in over low heat until fully melted.
The dish is too spicy. The Cajun seasoning blend or the andouille was hotter than expected. Start with 1½ tablespoons of seasoning, taste before adding more, and serve red pepper flakes on the side rather than in the pot.
The pasta is undercooked in the center. The simmer time was too short, or the pan was too crowded. Add a splash of broth, cover for 2 minutes, and check again — one-pot pasta finishes fast once it’s close.
The sauce tastes flat. It needs salt or acid. Taste after the Parmesan goes in; add salt if needed, and a squeeze of lemon or a splash more tomato brightens it.
Storage and Make-Ahead
Store the pasta in a sealed container in the refrigerator for up to 3 days. It thickens significantly as it chills; reheat gently on the stovetop with a splash of broth or milk, stirring until the sauce loosens. Reheat to 165°F before serving.
I don’t recommend freezing this dish. The pasta absorbs the sauce and softens, and the cream cheese sauce can separate when thawed. If you freeze it anyway, thaw overnight in the refrigerator and reheat gently, accepting a softer texture.
You can sear the sausage and slice the peppers up to a day ahead, then store them separately in the refrigerator. Mix the seasoning blend and keep it in a jar for months.
Store leftovers in the refrigerator within 2 hours of cooking, and discard anything left at room temperature for more than 2 hours.

FAQ
Can I use a different pasta shape?
Yes. Penne rigate is the most forgiving because the ridges hold the sauce and it cooks evenly in one-pot timing. Rigatoni works but needs a minute or two longer. Tortellini cooks faster and absorbs less liquid, so reduce the broth and check it earlier.
Can I use kielbasa instead of andouille?
Yes, but kielbasa is milder and sweeter. The dish will be less spicy, and you may want a little more Cajun seasoning to compensate.
Can I make this less spicy?
Start with 1½ tablespoons of Cajun seasoning instead of 2, use a mild andouille or kielbasa, and serve red pepper flakes on the side rather than in the pot. Taste the sauce after the tomatoes go in, before adding more seasoning.
Can I make this without cream cheese?
You can substitute heavy cream or a splash of milk whisked with a little cornstarch, but the texture will be thinner, and the sauce won’t cling the same way. I haven’t tested a dairy-free version, so I can’t vouch for the result.
Can I add vegetables?
Yes. Sliced zucchini, mushrooms, or spinach all work. Add firmer vegetables with the peppers, and stir in the spinach at the very end, off the heat.
How do I keep leftovers from drying out?
Store them in the container with a splash of broth or milk, and reheat gently on the stovetop rather than in the microwave. The pasta absorbs the sauce as it chills; the liquid loosens it back to a creamy consistency.
