A quick and easy creamy chicken cordon bleu casserole that combines tender chicken, savory ham, and melty Swiss cheese in a luscious sauce, perfect for family dinners and meal prep.

Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts, cooked and shredded or cubed
  • 6 ounces deli ham, chopped
  • 1.5 cups shredded Swiss cheese (about 170 grams)
  • 3 tablespoons unsalted butter (for roux)
  • 3 tablespoons all-purpose flour
  • 2 cups whole or 2% milk
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon Dijon mustard
  • Salt and freshly ground black pepper to taste
  • 1/2 cup panko breadcrumbs (about 50 grams)
  • 1 tablespoon olive oil or melted butter (for toasting breadcrumbs)
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or non-stick spray.
  2. If not already cooked, poach or bake chicken breasts until fully cooked (internal temperature 165°F), then shred or cube them.
  3. Dice the deli ham into bite-sized pieces.
  4. In a medium saucepan over medium heat, melt butter. Whisk in flour and cook for about 2 minutes to form a roux.
  5. Gradually whisk in milk, continuing to whisk until sauce thickens and is smooth, about 5-7 minutes.
  6. Stir in garlic powder, onion powder, Dijon mustard, salt, and pepper. Whisk to combine.
  7. Remove sauce from heat and fold in shredded Swiss cheese until melted and smooth.
  8. In the greased baking dish, mix shredded chicken and chopped ham evenly. Pour the cheese sauce over and gently stir to coat everything.
  9. In a small bowl, toss panko breadcrumbs with olive oil or melted butter. Sprinkle evenly over the casserole.
  10. Bake for 25-30 minutes until the topping is golden brown and casserole is bubbling.
  11. Let rest for 5 minutes. Garnish with chopped parsley if desired before serving.

Notes

Use good quality Swiss cheese like Emmental or Jarlsberg for best melting. For gluten-free, substitute flour and breadcrumbs with gluten-free alternatives. To make breadcrumb topping extra crispy, toast with butter and broil 1-2 minutes at the end. The casserole can be assembled a day ahead and refrigerated; add 5-10 minutes to baking time if baking from cold. Leftovers reheat well in oven covered with foil.
