16 slices English muffin bread or firmer white bread, crusts removed
8 slices cheddar cheese
8 slices Swiss cheese
¼ to 1/2 pound thinly sliced ham
3 cups milk
1/2 teaspoon dry mustard
1/2 teaspoon salt
3 cups crushed cornflakes
1 stick butter, melted
Spray a 9 x 13 inch pan with cooking spray. Cover bottom of the pan with a layer of bread.
Top each piece of bread with a piece of cheddar cheese, some sliced ham and then Swiss cheese on top. Top each sandwich with another layer of bread. In a large bowl, whisk together eggs, milk, salt and dry mustard. Pour egg mixture over the sandwiches. Cover and refrigerate at least a few hours or overnight.
Mix together melted butter and cornflakes. Before baking sprinkle crushed cornflake mixture over the top of the casserole. Bake loosely covered in foil in a preheated 350 degree oven for 45 to 50 minutes. Uncover and bake another 10 to 15 minutes or until it’s golden on top. Let rest 5 to 10 minutes before slicing into squares.
