Ingredients

Scale

  • 5 cups shredded cooked chicken

  • 9 oz sliced deli-style Black Forest ham, cut into strips (about 9 slices)

  • 8 oz sliced Swiss cheese (about 12 thin slices)

  • 6 tablespoons unsalted butter

  • 1 tablespoon Dijon mustard

  • 1 tablespoon freshly squeezed lemon juice (optional)

  • 1 teaspoon garlic powder

  • ½ teaspoon salt

  • ¼ teaspoon nutmeg (optional)

  • ¼ teaspoon cayenne pepper (optional)

  • 6 tablespoons all-purpose flour

  • 3 cups whole milk

  • 1½ cups panko breadcrumbs

  • 4 tablespoons unsalted butter, softened

  • Chopped parsley (optional, for garnish)

Instructions

  1. Preheat the oven to 350°F (175°C) and spray a 9×13-inch casserole dish with nonstick cooking spray.

  2. Evenly spread the shredded chicken across the bottom of the baking dish.

  3. Layer the ham strips evenly over the chicken.

  4. Arrange the Swiss cheese slices over the ham, slightly overlapping as needed.

  5. In a saucepan over medium heat, melt 6 tablespoons butter.

  6. Whisk in the Dijon mustard, lemon juice (if using), garlic powder, salt, nutmeg (if using), and cayenne pepper (if using).

  7. Sprinkle in the flour and whisk continuously until a smooth paste forms.

  8. Slowly add the milk, about ¼ cup at a time, whisking well after each addition.

  9. Let the sauce simmer for about 4 minutes, whisking occasionally, until thickened.

  10. Pour the sauce evenly over the casserole, spreading it into the corners.

  11. In a small bowl, mix the panko breadcrumbs with the softened butter. Sprinkle evenly over the top.

  12. Bake uncovered for 30–40 minutes, until the sauce is bubbling and the topping is golden brown.

  13. Let the casserole rest for 5 minutes before serving. Garnish with chopped parsley if desired.

Notes

  • Use rotisserie chicken to save time and add extra flavor.

  • Thin cheese slices melt best, ensuring even coverage.

  • Adjust seasoning: Skip nutmeg and cayenne for a classic mild version, or include them for depth and warmth.

  • Crispier topping: Broil for the last 1–2 minutes if desired (watch closely).

  • Make ahead: Assemble the casserole up to 24 hours in advance and bake when ready.
