One pot. Smoky sausage, tender chicken, sweet peppers, and pasta that cooks right in the sauce it will be served in. This creamy Cajun pasta is weeknight cooking at its most satisfying: gently spicy, rich without being heavy, and deeply flavored in a way that tastes like a restaurant pasta night. The noodles simmer directly in seasoned broth and cream, releasing starch as they go, and that starch quietly thickens everything into a silky sauce that clings to every piece.
From the first chop to the table, you are looking at about 35 minutes, and the washing up is one pot and a cutting board. It also has a habit of getting requested again before the leftovers are even cold. Plan accordingly.
The Starch Is the Sauce
Cooking the pasta in the pot with everything else is more than a shortcut. It is a sauce strategy. As the penne simmers, it sheds starch into the liquid, and that starch turns broth and cream into one cohesive, glossy sauce with no flour or cornstarch anywhere near it. Building the base in order matters, too: the sausage and chicken brown first, the vegetables soften in those drippings and pick up the smoky flavor, and the cream waits until the pasta is nearly done, so it stays smooth and never boils long enough to split. Last detail, and it counts: the Cajun seasoning goes in twice, once with the vegetables and once at the end, which layers the heat instead of leaving it one-note.
Into the Pot Goes
- 1 tablespoon olive oil
- 8 ounces smoked andouille sausage, sliced into rounds (kielbasa works too)
- 1 pound boneless, skinless chicken breast or thighs, cut into bite-size pieces
- 2 tablespoons Cajun seasoning, divided
- 1 medium yellow onion, diced
- 1 red bell pepper and 1 green bell pepper, sliced
- 3 garlic cloves, minced
- 3 cups low-sodium chicken broth
- 1 can (14.5 ounces) diced tomatoes, undrained
- 12 ounces penne pasta
- 3/4 cup heavy cream
- 1/2 cup grated parmesan, plus more for serving
- 2 green onions, sliced, for serving
- Salt and black pepper to taste
One Pot, Start to Finish
- Heat the olive oil in a large, deep pot or Dutch oven over medium-high heat. Brown the sausage slices for 3 to 4 minutes until the edges caramelize. Remove to a plate.
- Season the chicken with 1 tablespoon of the Cajun seasoning. In the same pot, cook the chicken for 5 to 6 minutes until browned and cooked through. Remove to the plate with the sausage.
- Lower the heat to medium. Cook the onion and bell peppers in the drippings for 4 to 5 minutes until softened. Stir in the garlic and the remaining Cajun seasoning and cook for 30 seconds.
- Pour in the chicken broth and diced tomatoes, scraping up the browned bits from the bottom of the pot. Bring to a boil.
- Stir in the penne. Reduce to a steady simmer, cover, and cook for 11 to 13 minutes, stirring every few minutes so nothing sticks, until the pasta is just tender.
- Uncover and stir in the cream and parmesan. Simmer 2 minutes until the sauce thickens slightly.
- Return the sausage and chicken with their juices to the pot. Stir and heat through for 1 to 2 minutes.
- Taste and adjust salt, pepper, and heat. Serve in bowls topped with green onions and extra parmesan.
Small Rituals for One-Pot Success
- Stir the pasta as it cooks. One-pot pastas stick to the bottom when left alone. A stir every 3 minutes keeps everything even.
- Watch the liquid level. Pasta brands absorb differently. If the pot looks dry before the pasta is tender, add broth a splash at a time.
- Respect the seasoning blend. Cajun blends vary wildly in salt and heat. Start with the amount listed, taste, and let hot sauce at the table handle the heat-seekers.
- Cream goes in late. That timing keeps the sauce smooth instead of reducing into an oily layer.
- Let it stand 5 minutes. Off the heat, the sauce thickens and coats the pasta better. Those five minutes are part of the recipe.
Other Pots This Could Become
- Shrimp version: Swap the chicken for shrimp, but add the shrimp only in the last 3 to 4 minutes so they stay plump.
- Vegetarian: Skip the meats, use vegetable broth, and add zucchini, mushrooms, and a can of drained chickpeas.
- Extra smoky: Add 1/2 teaspoon of smoked paprika and a diced chipotle pepper in adobo.
- Lighter: Half-and-half instead of cream, and turkey sausage instead of andouille.
Leftovers and the Freezer Question
Leftovers refrigerate for up to 3 days. The pasta will keep absorbing sauce as it sits, so reheat gently on the stove or in the microwave with a splash of broth or cream, stirring halfway, until it is hot and glossy again. Freezing the finished dish does not work well; cooked noodles turn soft. If freezing is the plan, freeze the sauce and meats without pasta and cook fresh pasta when you serve.
Cajun Pasta, Your Questions
Can I use a different pasta shape?
Yes. Rotini, fusilli, and rigatoni all work well. Avoid long strands like spaghetti in one-pot cooking; they clump and cook unevenly.
How spicy is this pasta?
Mildly to moderately spicy, depending on your Cajun blend. Most of the heat is warm rather than sharp. Cut the seasoning to 1 1/2 tablespoons for a gentler pot.
My sauce is too thin. How do I fix it?
Simmer uncovered for a few extra minutes, stirring, and add a little more parmesan. The sauce also thickens noticeably as it rests.
Can I make it ahead?
It is best fresh, because pasta keeps absorbing sauce. If you must, undercook the pasta by 2 minutes and reheat gently with extra broth.
Reading the Ingredient List
- Andouille sausage: This smoked pork sausage is the deep, smoky base note of the whole dish. Kielbasa is the easiest substitute and a little milder. Smoked turkey sausage works for a lighter pot and still browns nicely.
- Cajun seasoning: Blends vary in salt and heat, so know yours. A salt-free blend means you will likely add salt at the end; a salty blend means taste before adding any. Making your own from paprika, garlic powder, onion powder, oregano, thyme, and cayenne gives you full control.
- Chicken: Thighs stay juicier in this kind of cooking and forgive a lot. Breasts work too. Either way, cut the pieces to a similar size so they finish together.
- Diced tomatoes: Fire-roasted diced tomatoes add a whisper of smoke that suits the Cajun profile. Regular diced tomatoes are perfectly fine.
- Heavy cream: Cream gives the sauce body and keeps it stable as it simmers. Half-and-half makes a lighter sauce; whisk in a teaspoon of cornstarch if you want the same cling.
- Penne: Short, sturdy shapes are best for one-pot cooking. Whatever shape you choose, keep the weight the same and expect the timing to shift by a minute or two.
Next to the Pot
The pasta is rich, so the best partners are fresh and simple. A green salad with a tangy vinaigrette cuts through the cream, and garlic bread is never unwelcome for swiping the bowl clean. Corn on the cob or a quick cucumber and tomato salad keeps the Southern spirit going. Feeding a crowd? Set out extra hot sauce and parmesan and let everyone finish their own bowl. The pot itself can go straight to the table, which suits the casual, generous feel of the dish perfectly.
When a One-Pot Pasta Acts Up
Sticking pasta means the heat ran a touch high or the stirring lapsed. Keep the simmer steady rather than aggressive, and stir on schedule. A sauce that looks soupy at the end of cooking usually just needs patience: penne keeps drinking liquid as it stands, so give the pot five minutes off the heat before judging, then simmer a few minutes more if it still needs it. Too thick, on the other hand, is a ten-second fix: a splash of broth loosens it instantly. The most common mistake of all is walking away during the pasta stage. Set a timer, treat the stirs as part of the recipe, and the pot rewards you with a sauce that needs no thickeners at all.
Can I use milk instead of cream?
You can, but the sauce will be thinner and more likely to look separated. If milk is the plan, whisk 2 teaspoons of cornstarch into it first and add it at the very end, just heating through.
Doubling It for a Crowd
This recipe doubles well in a large Dutch oven or stockpot, which makes it a smart pick for team dinners and casual gatherings. Keep the ratios the same, but brown the sausage and chicken in batches so they caramelize instead of steaming, and expect the pasta to need an extra minute or two, since a fuller pot returns to a simmer more slowly. Hold the finished pot over the lowest heat with an occasional stir and a splash of broth. Then set it in the middle of the table with bowls, extra parmesan, green onions, and hot sauce, and let everyone serve themselves. Few dinners make a cook look this generous for this little work.
