Ingredients
Scale
Meat and Cheese
- 3 cups cooked chicken, shredded or cubed
- 1 1/2 cups cooked ham, diced
- 2 cups shredded Swiss cheese, divided
Dressing and Seasoning
- 1/2 cup sour cream
- 1/4 cup milk
- 1 tablespoon Dijon mustard
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- Salt and pepper to taste
Topping (Optional)
- 1/2 cup bread crumbs, plain or seasoned
- 2 tablespoons melted butter
Instructions
- Preheat and Prepare Dish: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish to prevent sticking and ensure easy serving after baking.
- Combine Main Ingredients: In a large mixing bowl, mix the shredded or cubed cooked chicken, diced ham, and 1 1/2 cups of shredded Swiss cheese evenly to create the casserole base.
- Make the Sauce: In a separate bowl, whisk together the sour cream, milk, Dijon mustard, garlic powder, onion powder, salt, and pepper until you achieve a smooth, creamy mixture that will bind the casserole.
- Mix Sauce with Protein: Pour the prepared sauce over the chicken and ham mixture, stirring gently to ensure all the ingredients are fully coated and flavors meld.
- Assemble in Baking Dish: Transfer this combined mixture into the greased baking dish, spreading it out evenly for consistent cooking.
- Add Cheese Topping: Evenly sprinkle the remaining 1/2 cup of Swiss cheese on top to provide a rich, melted cheesy crust.
- Prepare and Add Breadcrumb Topping: If using, mix the bread crumbs with melted butter in a small bowl, then sprinkle this over the cheese layer to add a crunchy texture after baking.
- Bake the Casserole: Bake in the preheated oven for 25-30 minutes, until the casserole is hot throughout and the top is bubbly and golden.
- Rest and Serve: Allow the casserole to cool for a few minutes before serving to let it set and ensure easier slicing.
Notes
- Using freshly cooked chicken and ham will yield the best flavor and texture.
- The breadcrumb topping is optional but adds a delightful crunch; skip for a softer topping.
- Feel free to substitute Swiss cheese with Gruyère for a nuttier taste.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven for best results.
