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
Dairy and Sauce
- 1/2 cup sour cream
- 1/4 cup milk
- 1 tablespoon Dijon mustard
Spices and Seasonings
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- Salt and pepper to taste
Toppings (Optional)
- 1/2 cup bread crumbs, plain or seasoned
- 2 tablespoons melted butter
Instructions
- Preheat the oven and prepare the baking dish: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish thoroughly to prevent sticking and ensure easy cleanup.
- Combine the main ingredients: In a large mixing bowl, mix together the cooked chicken, diced ham, and 1 1/2 cups of shredded Swiss cheese. This forms the hearty base of your casserole.
- Make the creamy sauce: In a separate bowl, whisk together the sour cream, milk, Dijon mustard, garlic powder, onion powder, salt, and pepper until smooth. This mixture adds the classic creamy and tangy flavor to the casserole.
- Mix sauce with chicken and ham: Pour the creamy sauce mixture over the chicken and ham mixture. Stir gently but thoroughly to coat all the ingredients evenly with the sauce.
- Assemble the casserole: Transfer the combined mixture into the prepared baking dish, spreading it out evenly to ensure uniform baking.
- Add cheese topping: Sprinkle the remaining 1/2 cup of shredded Swiss cheese evenly over the top of the casserole for that signature melted cheese layer.
- Prepare optional breadcrumb topping: In a small bowl, mix the bread crumbs with the melted butter until well combined. Then, sprinkle this mixture evenly over the cheese layer to create a crunchy topping.
- Bake the casserole: Place the dish in the preheated oven and bake for 25-30 minutes, or until the casserole is heated through, the cheese is melted, and the topping is golden and bubbly.
- Cool and serve: Allow the casserole to cool for a few minutes after baking to set slightly before serving. This helps the casserole hold its shape and improves the dining experience.
Notes
- You can use plain or seasoned bread crumbs for the topping, depending on your taste preference.
- Substitute the Swiss cheese with Gruyère or mozzarella for a different but delicious flavor.
- Leftovers can be refrigerated in an airtight container for up to 3 days and reheated in the oven or microwave.
- For a lower-fat version, use reduced-fat sour cream and cheese, and omit the butter from the breadcrumb topping.
- Ensure chicken and ham are fully cooked before assembling to guarantee proper food safety.
