Step 1

Gather all your ingredients. Preheat your oven to 350 degrees Fahrenheit (175°C) and lightly grease a 9x13-inch baking dish.

Step 2

In a large pot, boil lightly salted water. Cook the egg noodles in boiling water, stirring occasionally. Let them cook until they're tender yet firm to bite for 7 to 9 minutes. Drain and set them aside.

Step 3

Combine the cooked egg noodles, chopped chicken breast, cubed ham, and Swiss cheese in a large bowl. Set it aside.

Step 4

Mix the cream of chicken soup, milk, and sour cream in a separate bowl until well combined. Pour this mixture over the chicken, ham, and cheese. Stir until everything is well-coated.

Step 5

Transfer the noodle mixture to your prepared baking dish, spreading it out evenly.

Step 6

In a small pan, melt the butter over medium heat. Add the seasoned bread crumbs and stir until they're coated in the butter. Cook them for 2 to 3 minutes.

Step 7

Sprinkle the breadcrumb mixture evenly over the noodle mixture in the baking dish.

Step 8

Place the casserole in the preheated oven. Bake it for 30 minutes until it's hot and bubbly and the breadcrumb topping is golden brown.

Step 9

Allow the casserole to cool for 10 minutes, serve, and enjoy!
