Making Chicken Rigatoni Alfredo can be as simple as following these steps:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add rigatoni pasta and cook according to package instructions until al dente. Drain and set aside.
2. Prepare the Chicken: While the pasta cooks, season the chicken breasts with salt and pepper on both sides.
3. Cook the Chicken: In a large skillet, heat the olive oil over medium heat. Add the chicken breasts and cook for 6-7 minutes per side until golden and cooked through. Once done, remove from the skillet and let rest for a few minutes before slicing.
4. Sauté Garlic: In the same skillet, add minced garlic and sauté for about 30 seconds until fragrant.
5. Make the Alfredo Sauce: Pour in the heavy cream, and bring to a simmer. Stir in the Parmesan cheese and Italian seasoning. Cook for 2-3 minutes until the sauce thickens slightly.
6. Combine Pasta and Sauce: Add the drained rigatoni to the skillet, tossing well to coat all the pasta in the creamy sauce.
7. Add Chicken: Slice the cooked chicken and place it on top of the pasta. Toss gently to combine.
8. Serve: Once everything is combined, adjust seasoning if needed, and remove from the heat.

These steps naturally guide the creation of a magnificent Chicken Rigatoni Alfredo with ease.
