Gather Your Ingredients

Using simple, easy-to-find ingredients is key to this recipe’s success. Here’s what you’ll need:
The Main Players
- 1 tablespoon olive oil: For sautéing.
- 1 pound (450g) smoked sausage or Andouille sausage: Sliced into ¼-inch rounds. Andouille provides authentic flavor, but any good-quality smoked kielbasa works.
- 1 medium yellow onion: Diced.
- 1 green bell pepper & 1 red bell pepper: Cored, seeded, and sliced into thin strips. The color is fantastic!
- 3-4 cloves garlic: Minced.
The Liquid & Seasoning Base
- 2 tablespoons Cajun seasoning: Use a store-bought blend or make your own (see tips). Adjust based on spice preference and brand saltiness.
- 1 teaspoon dried oregano
- ½ teaspoon freshly ground black pepper
- 1 (14.5 oz) can diced tomatoes: Undrained. They add a touch of acidity.
- 4 cups (946 ml) low-sodium chicken broth: Using low-sodium allows you to control the salt level.
- 1 pound (450g) penne pasta: Or any short pasta like fusilli, rigatoni, or farfalle.
The Creamy Finish
- ½ cup (120 ml) heavy cream: For that luscious, rich texture. Half-and-half can be used for a lighter version.
- 1 cup (100g) freshly grated Parmesan cheese: Plus extra for serving. Freshly grated melts much better than pre-shredded.
- Salt, to taste: Always taste before adding extra salt.
- Fresh parsley or green onions: Chopped, for garnish.
Step-by-Step Instructions
Follow these simple steps for a foolproof, delicious result.
Step 1: Brown the Sausage
In a large pot or Dutch oven over medium-high heat, add the olive oil. Once hot, add the sliced sausage. Cook for 4-5 minutes, stirring occasionally, until the sausage is nicely browned on both sides. Using a slotted spoon, remove the sausage to a plate, leaving the flavorful drippings in the pot.
Step 2: Sauté the Veggies
Add the diced onion and sliced bell peppers to the pot. Cook in the sausage drippings for 5-6 minutes, until they begin to soften and the onions turn translucent. Add the minced garlic and cook for just 30 seconds until fragrant—be careful not to burn it.

Step 3: Build the Sauce & Cook the Pasta
Stir in the Cajun seasoning, oregano, and black pepper, coating the vegetables. Pour in the undrained diced tomatoes and the chicken broth. Use your spoon to scrape up any browned bits from the bottom of the pot this is packed with flavor!
Add the uncooked pasta and the browned sausage back into the pot. Give everything a good stir. Bring the mixture to a rolling boil.
Step 4: Simmer to Perfection
Once boiling, reduce the heat to medium-low, cover the pot with a lid, and let it simmer for 12-15 minutes. Stir every 4-5 minutes to prevent sticking. Cook until the pasta is al dente and most of the liquid has been absorbed. The sauce will still look a bit liquidy at this stage.
Step 5: Create the Creamy Magic
Turn the heat to low. Stir in the heavy cream and the freshly grated Parmesan cheese. Keep stirring until the cheese is completely melted and the sauce becomes creamy and cohesive. Let it simmer gently, uncovered, for another 2-3 minutes to thicken slightly. Taste and adjust seasoning, adding salt only if needed (remember, the sausage, broth, and cheese are salty).
Step 6: Serve & Enjoy!
Remove the pot from the heat. Garnish generously with chopped fresh parsley or green onions. Serve immediately in bowls with extra Parmesan cheese on the side.
Useful Tips for Perfect Pasta Every Time
- Control the Heat: Cajun seasoning blends vary wildly in salt content and spiciness. Start with 1.5 tablespoons if you’re sensitive to heat, then add more at the end if desired. For a homemade blend, mix: 2 tsp paprika, 1 tsp each garlic powder, onion powder, and dried oregano, ½ tsp each cayenne pepper, black pepper, and thyme.
- Pasta Choice: Short, sturdy pastas with ridges or shapes (like penne, cavatappi, or cellentani) are ideal as they hold the creamy sauce beautifully.
- Don’t Skip the Scrape: When you add the broth, thoroughly scrape the browned bits (fond) from the bottom of the pot. This deglazing step is essential for deep flavor.
- Cream Concerns: To prevent curdling, ensure the heat is on low when adding the cold cream and cheese. Letting the dish sit for 5 minutes off the heat before serving also helps the sauce thicken perfectly.
- Protein Swaps: Not a sausage fan? Try this with diced chicken breast (add with the veggies) or shrimp (add in the last 3-4 minutes of cooking).
- Veggie Boost: Feel free to add sliced mushrooms with the peppers or a handful of spinach at the very end, stirring until wilted.
Frequently Asked Questions (FAQs)
Can I make this ahead of time?
Yes, but the pasta will continue to absorb liquid. Store it in an airtight container in the fridge for up to 3 days. Reheat on the stovetop with a splash of broth or cream to loosen the sauce.
Can I freeze creamy Cajun pasta?
We don’t recommend freezing this dish. Dairy-based sauces can separate and become grainy upon thawing, and the pasta will turn very soft.
How can I make it lighter?
Substitute the heavy cream with half-and-half or full-fat coconut milk. Use a leaner turkey sausage and reduce the amount of cheese slightly.
My sauce is too thin. How can I thicken it?
Let it simmer uncovered for a few extra minutes. You can also create a quick slurry by mixing 1 teaspoon of cornstarch with 1 tablespoon of cold water, then stirring it into the simmering sauce.
My sauce is too thick. What should I do?
Simply stir in a little more chicken broth, a quarter cup at a time, until you reach your desired consistency.
