Making Spicy Cajun Pasta with Sausage can be a fun and engaging experience. Just follow these clear steps:

1. Cook the Pasta: In a large pot, boil salted water and cook the penne pasta according to package directions until al dente. Drain and set aside.
2. Sauté the Sausage: In a large skillet, heat the olive oil over medium heat. Add the sliced sausage and cook until browned, about 5-7 minutes. Remove the sausage from the skillet and set aside.
3. Cook the Vegetables: In the same skillet, add the diced onion and bell pepper. Sauté until the onion is translucent, about 3-4 minutes. Then, add the minced garlic and cook for an additional 1 minute.
4. Add Tomatoes: Pour in the undrained diced tomatoes and bring the mixture to a simmer. Allow it to cook for about 5 minutes.
5. Incorporate Cream and Spices: Lower the heat and stir in the heavy cream, Cajun seasoning, salt, black pepper, and cayenne pepper, if using. Mix well and cook for another 3-4 minutes until the sauce thickens slightly.
6. Combine: Add the cooked sausage and drained pasta to the skillet. Toss everything together until the pasta is well-coated in the sauce. Ensure it’s heated through, about 2-3 minutes.
7. Garnish: Remove from heat and garnish with freshly chopped parsley.
8. Serve: Dish out the pasta onto plates and finish with grated Parmesan cheese, if desired.

Following these straightforward steps will lead you to create a heavenly meal that bursts with flavor!
