Ingredients

For the Casserole

  • 5-6 cups cooked shredded chicken
  • 1/2 lb. thinly sliced deli ham any variety
  • 1/4 lb. thinly sliced Swiss Cheese or 2 cups shredded mozzarella or provolone cheese

For the White Sauce

  • 4 Tbsp. butter
  • 4 Tbsp. flour
  • 3 cups whole milk
  • 2 Tbsp. lemon juice
  • 1 Tbsp. Dijon mustard
  • 1/2 tsp. salt
  • 1/2 tsp. smoked paprika
  • 1/4 tsp. pepper

For the Topping

  • 2 cups Panko breadcrumbs
  • 5 Tbsp. butter melted
  • 1/2 tsp. seasoning salt
  • 1/2 tsp. poultry seasoning
  • 1/2 tsp. lemon pepper

Instructions

For the Casserole

  • Preheat oven to 350 degrees.
  • Butter or lightly spray a 9x13 baking dish.
  • Put shredded chicken evenly in the bottom of the baking dish.
  • Sprinkle the ham over the top of the chicken.
  • Lay the slices of cheese over the ham, or sprinkle the shredded cheese over the ham.

For the White Sauce

  • Melt the butter in a medium-sized saucepan over medium heat.
  • Once the butter is melted, add the flour all at once and stir to make a roux. (It will look like thick paste).
  • Once it is smooth and bubbly, slowly pour in the milk while stirring quickly or using a whisk to make a smooth sauce.
  • Continue to cook over medium heat, stirring constantly, until the sauce thickens.
  • Add the lemon juice, mustard, salt, paprika, and pepper.
  • Bring the sauce barely to a boil and then remove from the heat.
  • Pour over the chicken, ham, and cheese.

For the Topping

  • Melt the butter in the microwave in a medium-sized bowl. Be sure to loosely cover the bowl to keep the butter from spattering.
  • Remove the bowl from the microwave and mix in the Panko, seasoning salt, poultry seasoning, and lemon pepper.
  • Sprinkle over the top of the casserole.
  • Bake uncovered for 45 minutes. Let cool for 10-15 minutes before serving.
