Gather all ingredients and prepare by chopping sausage, measuring cream, broth, seasoning, and vegetables.

Heat olive oil in a large pot over medium heat, add sausage and cook until browned, about 4-5 minutes.

Add chopped vegetables to the sausage and sauté for another 3-4 minutes until softened.

Add chicken broth, heavy cream, and Cajun seasoning, stir to combine, and bring to a gentle simmer for 2-3 minutes.

Add uncooked pasta, ensuring it's submerged in liquid. Increase heat to simmer and cook for 10-12 minutes.

Once pasta is al dente, adjust sauce consistency with more broth or cream if needed. Finish with parsley and Parmesan.

Serve hot and enjoy the creamy and flavorful dish.
