Cook the ravioli according to the package directions. Drain and set aside.

Preheat the oven to 375 degrees Fahrenheit. Grease a 13-inch by 9-inch baking dish with non-stick cooking spray.

In a mixing bowl, combine the chicken, half of the alfredo sauce, half of the mozzarella cheese, half of the Parmesan cheese, half of the basil, salt, and pepper.

Spread a thin layer of alfredo sauce into the bottom of the prepared baking dish.

Add one-third of the chicken mixture.

Repeat the layers ending with the ravioli.

Spread the remaining alfredo sauce over the top layer of ravioli.

Sprinkle the remaining mozzarella cheese and Parmesan cheese on the top of the casserole.

Bake the Chicken Ravioli Casserole until the cheese is bubbly and golden brown.

Top with a bit more chopped basil or parsley if desired. Let cool slightly and serve!
