Ingredients
  

Main Ingredients

  • 2 cups cooked chicken diced (rotisserie chicken works wonders here for speed!)
  • 1 cup diced cooked ham
  • 1 cup shredded Swiss cheese
  • 1 can condensed cream of chicken soup (10.5 ounce)
  • 1/2 cup milk
  • 1 teaspoon dried parsley
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper

Topping

  • 1 cup crushed Ritz crackers
  • 1/4 cup melted butter

Instructions
 

Preparation

  • Preheat your oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish.
  • In a medium bowl, whisk together the condensed cream of chicken soup, milk, parsley, garlic powder, and black pepper until smooth.

Assembly

  • Spread the diced cooked chicken evenly in the bottom of the prepared baking dish, then scatter the diced cooked ham over the chicken layer.
  • Pour the creamy soup mixture over the chicken and ham, ensuring even distribution.
  • Sprinkle the shredded Swiss cheese generously over the entire casserole.
  • In a small bowl, combine the crushed Ritz crackers and melted butter, mixing until thoroughly coated.
  • Sprinkle the buttery cracker mixture over the cheese layer.

Baking & Serving

  • Bake for 25-30 minutes, or until the casserole is bubbly and the topping is golden brown.
  • Let the casserole rest for 5-10 minutes before serving to allow the sauce to set.

Notes

Rotisserie chicken can significantly reduce prep time. For a richer flavor, consider adding a pinch of thyme to the soup mixture. Make sure to let the casserole rest for at least 5 minutes before serving to ensure the sauce thickens nicely.
