Creating your own Creamy Parmesan Beef Rigatoni is a delightful process. Follow these simple steps:

1. Cook the Pasta: In a large pot of salted boiling water, cook the rigatoni according to package instructions until al dente. Drain and set aside.
2. Brown the Beef: In a large skillet, heat olive oil over medium heat. Add ground beef and cook until browned, breaking it apart with a spatula. This usually takes about 5-7 minutes.
3. Add Garlic: Stir in minced garlic and sauté for an additional 1-2 minutes until fragrant.
4. Create the Sauce: Pour in heavy cream, stirring well to combine. Bring the mixture to a simmer.
5. Incorporate Seasonings: Add Parmesan cheese, Italian seasoning, salt, and pepper. Stir until the cheese is melted and the sauce is smooth.
6. Combine with Pasta: Add the cooked rigatoni to the skillet, tossing to coat evenly in the creamy sauce.
7. Add Spinach: If using, stir in the spinach until wilted and combined with the pasta.
8. Serve Immediately: Remove from heat and garnish with fresh parsley before serving.

Following these steps ensures that your Creamy Parmesan Beef Rigatoni turns out perfectly every time.
