How to Make Creamy Chicken Cordon Bleu Casserole

Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch casserole dish.
Bring a large pot of salted water to a boil. Cook the egg noodles until al dente, about 7-9 minutes. Drain and place in the prepared casserole dish.
Layer the cooked chicken and cubed Swiss cheese on top of the noodles.
In a medium bowl, whisk together the cream of chicken soup, milk, and sour cream until smooth. Pour over the noodle mixture evenly.
In a skillet over medium heat, melt the butter. Stir in the breadcrumbs and Parmesan cheese until the crumbs are golden and well-coated.
Sprinkle the breadcrumb mixture on top of the casserole.
Bake for 30 minutes, or until the casserole is bubbling and the topping is golden brown. Let it cool for five minutes before serving.
