A cozy, cheesy casserole that combines classic chicken cordon bleu flavors in a quick, family-friendly dish with a creamy sauce and crispy breadcrumb topping.

Ingredients

Scale
  • 4 boneless, skinless chicken breasts (about 1.5 pounds / 680 grams), cut into bite-sized pieces
  • 1 cup diced ham (about 150 grams), deli-sliced or leftover baked ham
  • 1 ½ cups shredded Swiss cheese (about 170 grams), plus extra for topping
  • 3 tablespoons unsalted butter (about 43 grams), melted
  • 3 tablespoons all-purpose flour (about 24 grams)
  • 2 cups milk (480 ml), whole or 2%
  • 1 tablespoon Dijon mustard
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and freshly ground black pepper, to taste
  • 1 cup panko breadcrumbs (about 100 grams)
  • 2 tablespoons olive oil or melted butter

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. Heat 1 tablespoon of butter in a large skillet over medium heat. Add the bite-sized chicken pieces, season lightly with salt and pepper, and cook for 5-7 minutes until cooked through and no longer pink. Remove from heat and set aside.
  3. In a medium saucepan, melt the remaining 2 tablespoons of butter over medium heat. Whisk in the flour and cook for 1-2 minutes to form a roux. Slowly whisk in the milk, stirring constantly to prevent lumps. Add Dijon mustard, garlic powder, onion powder, salt, and pepper. Continue whisking until the sauce thickens, about 5 minutes.
  4. In a large mixing bowl, combine the cooked chicken, diced ham, shredded Swiss cheese (reserve some for topping), and the creamy sauce. Stir gently to mix.
  5. In a small bowl, toss the panko breadcrumbs with olive oil or melted butter until evenly coated.
  6. Pour the chicken mixture into a greased 9×13-inch baking dish. Sprinkle the reserved Swiss cheese over the top, then add the breadcrumb mixture as the final layer.
  7. Bake uncovered for 25-30 minutes until the topping is golden brown and the casserole is bubbly.
  8. Let the casserole rest for 5 minutes before serving.

Notes

If sauce is too thick, add a splash more milk. For a crispier crust, broil casserole for 1-2 minutes at the end, watching carefully to avoid burning. Use panko breadcrumbs for best crunch. For gluten-free, substitute breadcrumbs with almond flour or gluten-free panko. Dairy-free milk and cheese alternatives can be used but will alter flavor. Let casserole rest 5 minutes before serving to set.
