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

1. Cook the Pasta: In a large pot, cook the penne pasta according to package instructions. Drain and set aside.
2. Sauté the Sausage: In the same pot, heat olive oil over medium heat. Add the sliced sausage and sauté until browned, about 5 minutes.
3. Add Vegetables: Stir in the diced onion, bell pepper, and minced garlic. Cook until the vegetables are soft, about 5 minutes.
4. Add Tomatoes: Pour in the diced tomatoes along with their juice, stirring to combine. Allow the mixture to simmer for about 3 minutes.
5. Create the Sauce: Stir in the heavy cream and Cajun seasoning. Bring to a simmer, letting it thicken slightly for about 3-4 minutes.
6. Combine Pasta and Sauce: Add the cooked pasta to the pot, mixing well to ensure the pasta is coated with the sauce. Season with salt and pepper to taste.
7. Garnish: Remove from heat and sprinkle with fresh parsley. If desired, add grated Parmesan cheese for extra flavor.
8. Serve Warm: Enjoy the pasta hot, ensuring each plate has an enticing mix of sausage, pasta, and creamy sauce.

By following these steps, you’ll create a meal that is not only delicious but also impressively quick and easy.
