  • 1/2 cup sour cream
  • 1/4 cup milk

  • 1/4 teaspoon black pepper
  • 1 cup bread crumbs Panko or regular
  • 1/4 cup melted butter
  • 1/4 cup grated Parmesan cheese
  • 1/4 teaspoon paprika

Equipment

  • Large bowl
  • small bowl
  • whisk
  • Measuring cups
  • Measuring spoons
  • Oven

Method
 

  1. Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking dish.
  2. If you haven't already, cook and shred the chicken. Dice the ham and shred the Swiss cheese.
  3. In a large bowl, combine the shredded chicken, diced ham, and shredded Swiss cheese.
  4. In a separate bowl, whisk together the cream of chicken soup, sour cream, milk, mayonnaise, Dijon mustard, garlic powder, and black pepper until smooth.
  5. Pour the sauce over the chicken, ham, and cheese mixture. Stir well to combine everything.
  6. Pour the mixture into the prepared baking dish, spreading it evenly.
  7. In a small bowl, combine the bread crumbs, melted butter, Parmesan cheese, and paprika. Mix well until the bread crumbs are evenly coated.
  8. Sprinkle the bread crumb mixture evenly over the casserole.
  9. Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the topping is golden brown.
  10. Let the casserole cool for a few minutes before serving.

Notes

Don't overcook the chicken. Use high-quality ingredients for the best flavor. Dijon mustard adds a tangy flavor that elevates the casserole. Customize the topping with Italian seasoning or onion powder. You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat in the microwave or oven. To reheat in the oven, cover the casserole with foil and bake at 350°F (175°C) until heated through, about 15-20 minutes. Remove the foil during the last few minutes to crisp up the topping.
