For the Casserole:
- 4 cups cooked chicken, shredded or cubed
- 1 1/2 cups diced ham
- 6–8 slices Swiss cheese
For the Sauce:
- 4 tbsp unsalted butter
- 4 tbsp all-purpose flour
- 2 cups whole milk
- 1/2 cup chicken broth
- 1 tsp Dijon mustard
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp salt (or to taste)
- 1/4 tsp black pepper
For the Topping:
- 1 cup breadcrumbs (panko or regular)
- 2 tbsp unsalted butter, melted
- 1/4 cup grated Parmesan cheese
Instructions
- Preheat Oven:
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside. - Layer the Casserole:
Spread the cooked chicken evenly in the prepared baking dish. Sprinkle the diced ham over the chicken. Lay the Swiss cheese slices on top of the ham, ensuring full coverage. - Prepare the Sauce:
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux. Gradually whisk in the milk and chicken broth until smooth. Bring the mixture to a simmer and cook for 3-4 minutes, until thickened. Stir in the Dijon mustard, garlic powder, onion powder, salt, and black pepper. - Pour the Sauce:
Pour the prepared sauce evenly over the casserole, ensuring it covers all the layers. - Prepare the Topping:
In a small bowl, combine the breadcrumbs, melted butter, and grated Parmesan cheese. Sprinkle the topping evenly over the casserole. - Bake:
Bake the casserole in the preheated oven for 25-30 minutes, or until the topping is golden brown and the casserole is bubbling. - Serve:
Let the casserole rest for 5 minutes before serving. Serve hot with a side of green beans, a fresh salad, or mashed potatoes.
Notes
- Chicken Substitute: Rotisserie chicken works perfectly for this recipe to save time.
- Cheese Options: Swap Swiss cheese with provolone or mozzarella for a milder flavor.
- Make Ahead: Assemble the casserole up to 24 hours in advance, cover, and refrigerate. Bake as directed when ready.
