A comforting twist on the classic Chicken Cordon Bleu dish, this casserole combines savory chicken, hearty ham, and gooey Swiss cheese into a satisfying bake.

Ingredients

Scale
  • 2 lbs boneless, skinless chicken breasts or thighs, cut into 1-inch cubes
  • 1 tablespoon olive oil
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • 8 oz cooked ham, diced
  • 8 oz Swiss cheese, shredded
  • 1 (10.75 oz) can condensed cream of chicken soup
  • ½ cup milk
  • ½ cup mayonnaise
  • 1 tablespoon Dijon mustard
  • 1 teaspoon Worcestershire sauce
  • ¼ cup chopped fresh parsley
  • 1 cup breadcrumbs (optional)
  • ¼ cup grated Parmesan cheese (optional)
  • 2 tablespoons melted butter (optional)

Instructions

  1. Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish.
  2. Heat the olive oil in a large skillet over medium-high heat.
  3. Add the cubed chicken, salt, pepper, garlic powder, and onion powder. Cook until the chicken is fully cooked and lightly browned, about 5-7 minutes.
  4. In a mixing bowl, whisk together the cream of chicken soup, milk, mayonnaise, Dijon mustard, and Worcestershire sauce until smooth.
  5. Add the cooked chicken to the bowl with the soup mixture. Stir in the diced ham and shredded Swiss cheese until well combined.
  6. Pour the mixture into the greased baking dish, spreading it out evenly.
  7. If using, mix the breadcrumbs, Parmesan cheese, and melted butter in a small bowl. Sprinkle this mixture over the top of the casserole.
  8. Bake for 25-30 minutes, or until the casserole is bubbly and the topping is golden brown. Allow it to rest for 5-10 minutes before serving. Garnish with fresh parsley before serving.

Notes

For an even creamier texture, consider adding more milk or mayonnaise. For a crunchier topping, use panko breadcrumbs instead.
