Step-by-Step Instructions for Chicken Cordon Bleu Casserole
  1. Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking dish.
  2. Combine 3 cups of shredded or cubed cooked chicken and 1 ½ cups of diced cooked ham in a large mixing bowl.
  3. In a separate bowl, whisk together ½ cup sour cream, ¼ cup milk, 1 tablespoon Dijon mustard, ½ teaspoon garlic powder, ½ teaspoon onion powder, and salt and pepper to taste.
  4. Pour the creamy mixture over the chicken and ham, stirring gently to ensure every piece is well-coated.
  5. Transfer the mixture into your prepared baking dish, spreading it evenly across the bottom.
  6. Sprinkle 1 ½ cups of shredded Swiss cheese evenly over the top of the casserole.
  7. Mix ½ cup of bread crumbs with 2 tablespoons of melted butter and sprinkle over the cheese layer, if desired.
  8. Bake for 25-30 minutes until the cheese is bubbly and golden brown.
  9. Allow to cool for a few minutes before serving.
