Creating Garlic Butter Chicken Rigatoni with Creamy Parmesan Sauce is straightforward. Follow these step-by-step instructions for a fantastic meal:

1. Cook the Pasta: In a large pot of salted boiling water, cook the rigatoni according to the package instructions until al dente. Drain and set aside.

2. Sauté the Chicken: In a large skillet over medium heat, melt 2 tablespoons of butter. Add the bite-sized chicken pieces, seasoning them with salt and pepper, and cook until they are golden brown on all sides, about 5-7 minutes.

3. Add Garlic: Once the chicken is cooked through, add the minced garlic to the skillet. Sauté for about 1 minute, stirring frequently to prevent burning.

4. Create the Sauce: Pour in the heavy cream and add the Italian seasoning. Stir to combine, allowing the mixture to simmer for 2-3 minutes.

5. Incorporate Parmesan: Gradually add the grated Parmesan cheese while stirring until the cheese has melted and the sauce is creamy.

6. Combine Pasta and Sauce: Add the cooked rigatoni to the skillet, tossing it with the sauce to ensure every piece is well-coated. Cook for an additional 2-3 minutes to reheat the pasta.

7. Finalize with Butter: Stir in the remaining 2 tablespoons of butter until melted for an added richness.

8. Serve: Taste and adjust the seasoning if necessary. Serve hot, garnished with freshly chopped parsley.

These simple steps will yield a dish that is not only delicious but also visually appealing.
