Overnight Breakfast Casserole With Hash Browns, Bacon, and Ham

An easy overnight breakfast casserole made with bacon, ham, hash brown potato patties, mushrooms, eggs, and cheddar cheese. Serve this quick and easy casserole recipe for breakfast or brunch.

One of the reasons I like this particular breakfast casserole is that it uses hash brown patties instead of bread. If you have shied away from making these types of brunch casseroles in the past, you may like this one better than some others.

Because you fry the hash browns until they are crisp and golden, you get a much richer flavor from them than if you were to put them in just as cold shredded potatoes. Taking the time to do that step will result in a much better tasting casserole.

The combination of bacon and ham is always a winner when it comes to breakfast. You can leave out the mushrooms if you wish, but I do think they add flavor and texture to the dish. If you can buy fresh mushrooms, I would recommend them over canned mushrooms. If you do use canned mushrooms, be sure to drain them very well and press as much excess water out of them as you can.

As an added plus, since all of the ingredients get put directly in the pan, you will have very little clean up at the end of the day.

Serve a piece of hash brown casserole with a side of fresh fruit, toast and jam. My family liked this one a lot – mainly because it contains hash browns instead of bread.
