Ingredients
  

Casserole
  • 4 cups cooked chicken shredded or cubed
  • 1.5 cups diced cooked ham
  • 1.5 cups shredded Swiss cheese divided
  • 4 oz cream cheese softened
  • 1/2 cup sour cream
  • 1/2 cup milk
  • 2 tbsp Dijon mustard
  • 1 tsp garlic powder
  • 1/2 tsp salt
  • 1/4 tsp black pepper
Topping
  • 1 cup panko breadcrumbs
  • 1/4 cup unsalted butter melted
  • 1/4 cup grated Parmesan cheese

Equipment

  • 1 9x13 inch Baking Dish
  • 1 Large Mixing Bowl

Instructions
 

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
  2. In a large mixing bowl, combine the cooked chicken, diced ham, and 1 cup of the shredded Swiss cheese.
  3. In a separate medium bowl, whisk together the softened cream cheese, sour cream, milk, Dijon mustard, garlic powder, salt, and black pepper until smooth and well combined.
  4. Pour the cream sauce mixture over the chicken and ham. Stir gently until everything is evenly coated. Spread the mixture into the prepared baking dish. Sprinkle the remaining 1/2 cup of Swiss cheese over the top.
  5. In a small bowl, combine the panko breadcrumbs, melted butter, and grated Parmesan cheese. Mix until the breadcrumbs are fully moistened.
  6. Sprinkle the panko topping evenly over the casserole. Bake for 25-30 minutes, or until the filling is bubbly and the topping is golden brown and crisp.
  7. Remove from the oven and let it rest for 5-10 minutes before serving. This allows the casserole to set.

Notes

Make-Ahead Tip: Assemble the casserole without the topping and store it covered in the refrigerator for up to 24 hours. When ready to bake, add the topping and bake as directed, adding 5-10 minutes to the cook time.
Shortcut: Use a store-bought rotisserie chicken to save time on cooking and shredding chicken.
