Pour in the milk slowly and continue to whisk. Stir in the Dijon mustard, garlic powder, onion powder, nutmeg, salt and pepper. Allow the sauce to simmer over low heat for 2-3 minutes. It will be much thicker now. Remove from heat and set aside. 3 cups whole milk, 2 tablespoons Dijon mustard, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/4 teaspoon ground nutmeg, Salt and black pepper
In a large mixing bowl add the chicken, ham and cooked noodles. Pour the sauce over and gently mix together until everything is coated in the sauce. Fold in half the Swiss cheese. 16 ounces cooked & shredded chicken breast, 8 slices deli ham, 1 1/2 cups shredded Swiss cheese
Pour the chicken mixture in the baking dish and smooth out until even. Add the remaining cheese over the top.
In a small bowl, mix the Panko breadcrumbs and Parmesan cheese with the melted butter. Coat the top of the casserole evenly with the bread crumbs. 1 cup Panko breadcrumbs, 2 tablespoons melted butter, 1/4 cup freshly grated Parmesan cheese
Bake for 28-30 minutes until the casserole is bubbling and the topping has turned golden brown. Add the chopped parsley over the top. Serve while the casserole is hot. 2 teaspoons fresh parsley
