This one pot cajun sausage pasta cooks dry penne in broth, cream and undrained tomatoes after browning smoked sausage with onion and bell pepper. Pasta starch becomes part of the sauce, so there is no separate boiling pot or flour roux. Parmesan is stirred in off the heat once the noodles are tender. Keep the liquid at a gentle simmer and stir through the bottom so every piece cooks without scorching the creamy mixture.

Why This Recipe Works
Cooking everything together gives one pot cajun sausage pasta a sauce flavored by sausage juices and the pasta’s surface starch. The canned tomato liquid helps hydrate the penne, so draining that can would change the balance. Cream rounds out acidity and chile heat, while Parmesan adds salt and body at the end. A covered gentle simmer limits evaporation; the sauce continues to tighten as the pasta stands.
Ingredients for One Pot Cajun Sausage Pasta
Use fully cooked smoked sausage for one pot cajun sausage pasta, sliced into quarter-inch rounds. Fresh raw sausage needs a different initial cooking step. Dice a bell pepper and the medium onion finely enough to soften during the initial sauté. Keep all juices from the 14.5-ounce tomato can. Cajun blends vary in heat and salt: choose a milder blend when needed and hold extra salt until tasting.
Main Ingredients
- 1 lb smoked sausage, fully cooked, sliced into 1/4-inch rounds
- 12 oz dry penne pasta
- 2 cups chicken broth
- 1 cup heavy cream
- 1 medium onion, diced
- 3 cloves garlic
- 1 14.5-ounce can diced tomatoes, undrained
- 1 tbsp Cajun seasoning, choose mild if preferred
- 1 tsp paprika
- Salt and pepper, to taste
- 1 cup grated Parmesan cheese, finely grated, stirred in off heat
- 2 tbsp olive oil
- 1 bell pepper, diced
- hot water, only as needed, in 1/4-cup additions
How to Make One Pot Cajun Sausage Pasta
1. Brown sausage and soften vegetables. Heat the two tablespoons olive oil in a large deep pot over medium heat. Add sliced sausage, diced onion and diced bell pepper; stir for about 5–7 minutes until the vegetables start to soften and sausage edges color. If the vegetables brown too fast, lower heat. Stir in minced garlic for 30–60 seconds at the end so it does not burn during the longer sauté.
2. Add the measured liquid. Pour in broth, cream and tomatoes with every bit of their juice, then stir in Cajun seasoning and paprika. Bring just to a gentle boil rather than a hard rolling boil. Stir dry penne through the mixture and press the noodles under the liquid where possible. A wide shallow skillet evaporates faster than a deeper pot, so vessel shape affects whether extra water is needed.
3. Simmer covered and inspect often. Lower the burner, cover and maintain a gentle simmer. Begin testing penne around 10–12 minutes, following its package’s texture cues and continuing if the center is still hard. Stir thoroughly every few minutes, especially along the bottom. For one pot cajun sausage pasta, add hot water in quarter-cup increments only if liquid becomes scarce before the noodles are tender. That adjustment is safer than increasing heat to hurry them.
4. Finish with Parmesan. Once the pasta is al dente, remove the pot from heat and stir in the full cup of finely grated Parmesan. The old label called it garnish, but the original method folds it into the sauce. Taste before adding salt or pepper. Serve while the coating is still loose enough to spoon; if it tightens, stir in a little hot water rather than another large amount of cheese.
How to Serve
Divide one pot cajun sausage pasta into four substantial bowls and offer a crisp salad or plain vegetables alongside. Sausage, seasoning and Parmesan already supply a strong savory flavor. Extra parsley or cheese can be served separately if desired, but neither is necessary for the measured recipe. Keep a little sauce moving around the noodles as you portion so the final serving is not noticeably drier than the first.
For one pot cajun sausage pasta, slice sausage and dice vegetables before cooking, then keep ingredients refrigerated until needed. Use dry pasta at the simmering stage rather than substituting preboiled noodles, which would leave too much sauce liquid. The 40-minute estimate includes browning, heating liquid and pasta simmering. Brands, pot size and burner strength vary, so give the noodles extra time if their centers remain firm.
Storage and Reheating
Refrigerate leftover one pot cajun sausage pasta in shallow containers within two hours, or one hour above 90°F, and use within three to four days. Reheat to 165°F with a little water or broth, stirring gently to loosen the chilled coating. Reheating will make penne softer than at first serving. Do not leave a large pot at room temperature until completely cold; smaller portions cool more efficiently in the refrigerator.

Tips and Variations
- Undrained tomatoes matter in one pot cajun sausage pasta: their liquid is part of what cooks the dry pasta.
- Stir along the bottom, not only the top. Cream and pasta starch can stick even when the surface looks loose.
- A milder Cajun blend or mild smoked sausage reduces heat. Taste seasoning before adding extra salt, especially with regular broth.
Frequently Asked Questions
Does this require a second pasta pot?
No. Dry penne cooks in the measured broth, cream and tomato liquid. Stir and monitor that mixture closely.
Should tomatoes be drained?
No. Keep the can juices so there is enough liquid for the pasta.
What if one pot cajun sausage pasta dries out before pasta is tender?
Add hot water a quarter cup at a time and keep simmering gently. Check noodles rather than waiting for the sauce to become dry.
Can I use raw sausage?
The main method uses fully cooked smoked sausage. Raw sausage needs separate safe cooking before the rest of this sequence.
When is Parmesan added?
After the pot leaves the heat, once penne is tender. Fold in the full measured cup instead of treating it only as garnish.
