Preheat your stove to medium heat. Add the sausage to a large pot or deep skillet and cook until browned, about 5-7 minutes.

Toss in the diced onion and bell peppers. Sauté for about 3-4 minutes until onions are translucent.

Stir in minced garlic and cook for an additional minute. Add Cajun seasoning and toast for another minute.

Pour in the pasta and chicken broth, bring to a gentle boil. Cover and simmer for about 10-12 minutes until al dente.

Reduce the heat to low and stir in heavy cream and Parmesan cheese until the sauce is smooth and creamy.

Taste and adjust seasoning as necessary. Add broth if the sauce is too thick.

Serve hot, garnished with parsley or extra Parmesan if desired.
