Creating One Pot Creamy Cajun Sausage Pasta is straightforward. Follow these simple steps:

1. Heat Olive Oil: In a large pot or skillet, heat the olive oil over medium heat.
2. Cook Sausage: Add the sliced smoked sausage and cook until browned, about 5-7 minutes. Remove and set aside.
3. Sauté Vegetables: In the same pot, add the chopped onion, garlic, and bell pepper. Sauté until softened, around 3-4 minutes.
4. Add Pasta: Add the uncooked penne pasta to the pot and stir to combine with the vegetables.
5. Pour in Broth: Pour in the chicken broth and heavy cream. Stir well to ensure the pasta is submerged.
6. Seasoning: Add the Cajun seasoning, paprika, and salt and pepper to taste. Mix thoroughly.
7. Cook Pasta: Bring the mixture to a boil, then reduce to a simmer. Cover and cook for 12-15 minutes, or until the pasta is al dente.
8. Add Cheese: Once the pasta is cooked, stir in the shredded cheese until melted and creamy.
9. Return Sausage: Add the cooked sausage back into the pot and mix until everything is well combined.
10. Garnish: Remove from heat and garnish with sliced green onions before serving.
