This breakfast casserole is made with all of the great flavors of a Western omelet or Denver omelet. Ham, onion, and chopped bell pepper go into the easy one-dish breakfast casserole, along with cheddar cheese, cubed bread, and eggs. Add some tomatoes or mushrooms to the dish, or replace the ham with Canadian bacon, sausage, or bacon. See the tips and variations below the recipe for more ingredient and substitution ideas.

Make this easy breakfast casserole the night before. Refrigerate the casserole overnight and pop it in the oven in the morning. It's perfect for holiday mornings and family gatherings. 

For a hearty breakfast, serve the breakfast bake with juice and sweet rolls or cinnamon rolls. Or add sliced fresh fruit, berries, or a warm fruit compote. The Western omelet ingredients go well with ketchup or salsa on the side.
