Method
Preparation
- Preheat your oven to 350°F (175°C). Spray a 9x13-inch casserole dish with nonstick cooking spray.
- Evenly spread 5 cups of shredded chicken into the baking dish.
- Evenly layer 9 ounces of sliced black forest ham over the chicken, cut into strips for easy layering.
- Place 8 ounces of sliced Swiss cheese evenly over the ham, overlapping it to fit the dish.
Sauce Preparation
- Melt 6 tablespoons of unsalted butter in a saucepan over medium heat.
- Whisk in 1 tablespoon of Dijon mustard, lemon juice (if using), garlic powder, salt, nutmeg, and cayenne pepper.
- Sprinkle in 6 tablespoons of all-purpose flour and whisk until it forms a paste.
- Gradually add 3 cups of whole milk, mixing after each addition until smooth. Allow to simmer for 4 minutes until thickened.
Baking
- Pour the sauce over the cheese layer.
- Combine 1½ cups of Panko breadcrumbs with 4 tablespoons of softened butter, then spread it over the casserole.
- Bake for 30-40 minutes until bubbly and the topping is golden brown. Let sit for 5 minutes before serving.
Notes
Use rotisserie chicken for time-saving and great flavor. Don't skip the sauce as it binds the ingredients and adds creaminess. Let it sit for 5 minutes before serving. Cover with foil if browning too quickly. Experiment with different cheeses for varied flavors.
