Easy Breakfast Casserole With Ham Cheese

An easy breakfast casserole made with Italian bread, ham, eggs, onion, and Monterey Jack cheese you can make ahead the night before. Serve for breakfast or brunch.

One of the things I like the best about this casserole is using Monterey Jack cheese. Adding this cheese instead of cheddar gives the casserole a completely different flavor. Monterey Jack cheese is a semi-firm cheese with a mild flavor and creamy texture. It is similar in flavor to Muenster cheese, but is firmer and grates better. If you want a bit of a kick in your breakfast casserole, consider Pepper Jack cheese, which is a variation of Monterey Jack.

Substituting shredded cheddar cheese in this recipe is fine if that is what you happen to have on hand. It will still turn out good.

This is a hearty recipe for an evening family dinner, too. Serve it up with a side dish of vegetables for dinner or fresh fruit for brunch.

Make this breakfast casserole ahead the night before as it requires only a bit of additional cooking – just cooking the onions. All the other ingredients are ready to assemble with minor preparation. Then, just bake in the morning for an easy, stress-free meal.
