Ingredients
  

FOR THE CASSEROLE

  • 5 cups turkey chopped (Amount could vary, depending on the amount of leftovers!)
  • 5 cups ham chopped (Amount could vary, depending on the amount of leftovers!)
  • 1/4 lb swiss cheese thin sliced

FOR THE SAUCE

  • 4 tbsp butter
  • 4 tbsp flour
  • 3 cups whole milk a bit more if needed
  • 1 tbsp Dijon mustard
  • 3/4 tsp salt
  • 1/2 tsp smoked paprika
  • 1/4 tsp white pepper

FOR THE TOPPING

  • 1 1/2 cup Panko bread crumbs
  • 4 tbsp butter melted
  • 1/2 tsp seasoning salt
  • 1 1/2 tsp crushed dried parsley

Instructions
 

  • Preheat oven to 350 F.  

FOR THE CASSEROLE:

  • Butter a 2 1/2 quart baking dish.  Put the chopped turkey on the bottom of the dish.  Scatter the chopped ham over the top of the turkey.  Layer the swiss cheese on top of the ham.

FOR THE SAUCE:

  • Melt the butter in a large sauce pot over medium heat.  When butter is melted, quickly stir in the flour to form a smooth roux.  Be careful not to brown!  Once the roux is smooth and bubbly, slowly pour cold milk while whisking to make a smooth sauce.  Cook over medium heat, stirring constantly until the sauce thickens.  Stir in dijon mustard, salt, smoked paprika, and white pepper.  Bring sauce back to a low boil and then turn off the heat.  Pour sauce evenly over the entire casserole.

FOR THE TOPPING:

  • Melt the 4 tablespoons of butter in the microwave in a medium sized microwaveable bowl.  Heat it for 30 seconds at a time, stirring and stopping when it is melted.  Stir in the panko breadcrumbs and the crushed dried parsley.  Sprinkle over the op of the casserole.  
  • Bake casserole uncovered for 45 minutes.  Remove from oven once it is hot and bubbly throughout and the top has turned a light golden brown.  Allow to cool for 5-10 minutes before serving.
