Ingredients

Scale
  • 3 cups cooked chicken, shredded or cubed
  • 1 1/2 cups diced ham
  • 2 cups shredded Swiss cheese (or Gruyère)
  • 1 can (10.5 oz) cream of chicken soup
  • 1 cup milk or heavy cream
  • 1 tablespoon Dijon mustard
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper
  • 1 cup breadcrumbs or crushed Ritz crackers
  • 3 tablespoons melted butter
  • Optional: 1/2 cup sour cream or 2 tablespoons cream cheese for extra creaminess

Instructions

  1. Preheat oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
  2. In a bowl, whisk together the cream of chicken soup, milk, Dijon mustard, garlic powder, and black pepper until smooth.
  3. Spread cooked chicken evenly in the prepared baking dish.
  4. Top with diced ham and shredded Swiss cheese.
  5. Pour the sauce mixture evenly over the layers, ensuring full coverage.
  6. In a separate bowl, combine breadcrumbs with melted butter, then sprinkle over the top.
  7. Bake uncovered for 30–35 minutes or until golden brown and bubbly around the edges.
  8. Allow to cool for 5–10 minutes before serving to let the sauce thicken slightly.

Notes

  • Use rotisserie chicken for convenience and added flavor.
  • Substitute ham with turkey or cooked bacon if desired.
  • To freeze, assemble but don’t bake — cover tightly and freeze for up to 3 months.
  • Make it low-carb by using crushed pork rinds instead of breadcrumbs.
  • Add broccoli or bacon for extra flavor and texture.
