Ingredients

Scale

Main Ingredients

  • 3 cups cooked chicken, shredded or cubed
  • 1 ½ cups cooked ham, diced
  • 2 cups shredded Swiss cheese, divided
  • ½ cup sour cream
  • ¼ cup milk
  • 1 tablespoon Dijon mustard
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • Salt and pepper to taste

Topping (Optional)

  • ½ cup bread crumbs, plain or seasoned
  • 2 tablespoons melted butter

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish to prevent sticking.
  2. Combine Chicken, Ham, and Cheese: In a large mixing bowl, add the shredded or cubed cooked chicken, diced cooked ham, and 1 ½ cups of shredded Swiss cheese. Mix gently to combine.
  3. Mix Creamy Sauce: In a separate bowl, whisk together sour cream, milk, Dijon mustard, garlic powder, onion powder, salt, and pepper until the mixture is smooth and well blended.
  4. Combine Sauce with Meat Mixture: Pour the creamy sauce over the chicken, ham, and cheese mixture. Stir gently to ensure that all ingredients are evenly coated with the sauce.
  5. Transfer to Baking Dish: Pour the combined mixture into the prepared baking dish and spread it out evenly for uniform cooking.
  6. Add Cheese Topping: Sprinkle the remaining ½ cup of shredded Swiss cheese evenly over the top of the casserole.
  7. Add Breadcrumb Topping: In a small bowl, mix the bread crumbs with melted butter until combined. Sprinkle this mixture evenly over the cheese layer to add a crispy, golden crust.
  8. Bake the Casserole: Place the baking 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.
  9. Cool and Serve: Remove the casserole from the oven and let it cool for a few minutes before serving to allow the flavors to set and prevent burns.

Notes

  • You can use leftover rotisserie chicken or any cooked chicken for convenience.
  • For a gluten-free option, use gluten-free bread crumbs or omit the breadcrumb topping.
  • Adjust the seasoning to your taste, adding more Dijon mustard for extra tang.
  • If you prefer a richer casserole, substitute the milk with heavy cream.
  • The breadcrumb topping is optional but adds a nice texture contrast.
