01 - Heat olive oil in a large pot over medium-high heat. Add sliced sausage and Cajun seasoning, searing until browned on all sides.
02 - Incorporate minced garlic, sautéing for 1 minute. Pour in chicken broth and heavy cream, stirring to combine. Bring mixture to a gentle simmer.
03 - Add uncooked pasta to the pot. Stir well, cover, and cook, stirring occasionally, until pasta is al dente and sauce has thickened, approximately 12 to 14 minutes. Reduce heat if necessary to prevent sticking.
04 - Stir in shredded cheese until fully melted and creamy. Adjust seasoning to taste. Serve immediately.
