Creating One Pot Creamy Cajun Sausage Pasta is simple if you follow these steps:

1. Sauté the Sausage: In a large pot, heat the olive oil over medium heat. Add the sliced sausage and cook until browned, about 5 minutes.
2. Add Vegetables: Stir in the diced onion and bell pepper. Sauté until softened, about 3-4 minutes. Add in the minced garlic and cook for an additional minute.
3. Season: Sprinkle in the Cajun seasoning, paprika, and cayenne pepper (if using). Stir well to coat the sausage and vegetables with the spices.
4. Combine Pasta and Broth: Add the penne pasta to the pot. Pour in the chicken broth and stir to combine. Bring the mixture to a boil.
5. Cook Pasta: Reduce the heat to a simmer and cover the pot. Cook for 12-15 minutes, stirring occasionally, until the pasta is al dente and most of the liquid is absorbed.
6. Add Cream and Cheese: Remove the pot from heat. Stir in the heavy cream and shredded cheese until melted and creamy. Season with salt and pepper to taste.
7. Garnish and Serve: Top with freshly chopped parsley before serving for an added touch of freshness.
