Making the Creamy Cajun Sausage Pasta is a simple process. Follow these steps for a successful outcome:

1. Cook Pasta: In a large pot, boil salted water and cook the penne pasta according to package instructions until al dente. Drain well and set aside.
2. Sauté Sausage: In the same pot, heat olive oil over medium-high heat. Add the sliced sausage and cook until browned, about 5 minutes.
3. Add Vegetables: Toss in the diced onion, bell pepper, and minced garlic. Sauté for another 3-4 minutes until the vegetables soften.
4. Season the Mixture: Sprinkle in the Cajun seasoning, stirring to combine and let the flavors meld.
5. Pour in Liquids: Add the chicken broth and heavy cream to the pot, stirring gently. Bring to a simmer.
6. Incorporate Cheese: Reduce heat to low and stir in the parmesan cheese, mixing until the sauce is creamy and smooth.
7. Combine Pasta: Return the cooked penne pasta to the pot, tossing it gently to coat with the sauce. Add salt and pepper to taste.
8. Serve Immediately: Once everything is combined and heated through, remove from heat.
