Put half the bread in a buttered 9×13 pan.
Next add the diced ham, mushrooms, cheese and the rest of the bread.
Whip together eggs, milk and mustard. Pour over the bread. Cover the casserole with foil or plastic wrap and store in the fridge overnight.
The next morning, sprinkle the corn flakes over the top of the casserole and drizzle the melted butter over the cereal.
Bake at 350 for 60 minutes or until the top of the casserole is golden brown.
Let the casserole rest for a bit after you take it out of the oven. Serve and enjoy!
