Cook the Pasta
Bring a large pot of salted water to a boil. Cook the rigatoni pasta according to package instructions until al dente. Drain and set aside.
Cook the Chicken
Heat olive oil and butter in a large skillet over medium heat. Add the chicken pieces, season with salt and pepper, and cook for 5-7 minutes until golden brown and cooked through.
Add the Garlic
Stir in the minced garlic and cook for 1-2 minutes until fragrant.
Make the Creamy Sauce
Pour in the heavy cream and bring it to a gentle simmer. Add the Parmesan cheese and stir until melted and smooth, creating a creamy sauce.
Combine the Pasta
Add the cooked rigatoni to the skillet and toss to coat the pasta evenly with the creamy sauce. Adjust the seasoning with additional salt and pepper, if needed.
Serve
Serve the pasta hot, garnished with chopped parsley and an extra sprinkle of Parmesan cheese for added flavor.
