Method
Preparation
- Preheat the oven to 350°F (175°C). Spray a 9x13-inch casserole dish with nonstick cooking spray.
- Evenly spread the shredded chicken into the baking dish.
- Layer the sliced black forest ham over the chicken.
- Place the sliced Swiss cheese evenly over the ham, overlapping the cheese slices as needed.
Sauce Preparation
- Melt 6 tablespoons of unsalted butter in a medium saucepan over medium heat.
- Whisk in Dijon mustard, freshly squeezed lemon juice (if using), garlic powder, salt, nutmeg (if using), and cayenne pepper (if using).
- Sprinkle in all-purpose flour and whisk until it forms a smooth paste.
- Slowly add whole milk, a quarter of a cup at a time, whisking after each addition until the mixture is smooth.
- Allow the sauce to simmer for 4 minutes or until it thickens, whisking occasionally.
Assembly and Baking
- Pour the sauce over the cheese layer and spread it evenly across the casserole.
- In a small bowl, mix Panko breadcrumbs with softened unsalted butter and spread this mixture evenly over the casserole.
- Bake uncovered for 30-40 minutes, until the sauce is bubbling and the Panko topping is golden brown.
- Remove from the oven and let it sit for 5 minutes before serving. Optionally, sprinkle with chopped parsley.
Notes
Serve hot with a green salad, brown rice, or garlic bread for a hearty meal. Leftovers can be stored for 3-4 days in the refrigerator or frozen for up to 3 months.
