Country Brunch Breakfast Casserole - cooking recipe

Ingredients

16 slices firm white bread
2 1/2 cups cubed cooked ham (I use a ham steak)
16 ounces cheddar cheese, shredded
16 ounces mozzarella cheese, shredded
6 eggs
3 cups whole milk
1/2 teaspoon dry mustard
1/4 teaspoon onion powder
TOPPING
3 cups uncrushed corn flakes
1/2 cup butter, melted

Preparation

Trim crusts from bread; cut slices in half.
Grease a 13 x 9 x 2 inches baking pan (or slightly larger) and layer as follows: Cover bottom of pan with one-half of bread, one-half of ham and one-half of each of the cheeses.
Repeat layers.
Combine eggs, milk, and seasonings.
Pour over layers; refrigerate overnight.
Remove from refrigerator 30 minutes before baking.
Combine topping ingredients; sprinkle over casserole.
Bake 375 for 45-55 minutes (cover loosely with foil to prevent top from over browning).
Let stand 10-15 minutes before cutting into squares.
