Ham Egg Breakfast Casserole

A make-ahead ham egg breakfast casserole recipe made with ham, egg, bread, cheddar cheese, milk, and crushed cornflakes. Serve this egg casserole for breakfast or brunch.

This casserole takes only about 15 minutes to prepare the night before because all of the ingredients already cooked, cured, or prepared. Just take it out of the refrigerator and bake in the morning for a relaxing breakfast or brunch.

The crushed cornflakes on top give it a nice amount of crunch and also added flavor. Thankfully the recipe calls for a lot of crushed cornflakes mixed with melted butter, because this is what makes the recipe so good. If there are any leftover crumbs in the baking dish after breakfast, let the grazing begin!

I made this breakfast casserole with 3-day old Italian bread and it turned out to be a hit with my family. I would recommend day old bread for any breakfast casserole. If the bread is too fresh, the casserole seems to turn mushy.

It is made with items you normally have in your kitchen so that makes this casserole easy to put together when you have those unexpected guests staying over or are having guests for breakfast or brunch in the morning.
