Begin by boiling water in a large pot. Add the penne pasta and cook according to the package instructions. Once done, drain the pasta and set it aside.

In a large skillet, heat some olive oil over medium heat. Add the sliced sausage to the skillet and cook until browned, about 5-7 minutes.

Stir in the diced onion, bell pepper, and minced garlic. Cook everything until the vegetables are softened, about 3-5 minutes.

Pour in the heavy cream and sprinkle the Cajun seasoning into the skillet. Stir together and bring to a simmer.

Add the cooked penne pasta and shredded cheese to the skillet. Stir until the pasta is coated in the creamy sauce and everything is well combined.

Taste and season with salt and pepper as needed.

Before serving, sprinkle chopped parsley on top for a fresh touch.
