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.

Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.


  • To bake the casserole right away, prepare it and let it stand for 20 minutes. Bake in a preheated 350 F oven as directed, until set.

Recipe Variations

  • Use a combination of red and green bell peppers in the egg mixture.
  • Replace the cheddar cheese with a cheddar jack cheese blend or a Mexican blend of cheeses.
  • Replace the diced ham with 1 cup of cooked crumbled or thinly sliced breakfast sausage or some cooked and crumbled bacon (about 10 to 12 strips of bacon).
  • Add about 1/2 cup of diced seeded tomatoes to the ham and vegetable mixture.
  • Sauté 4 ounces of sliced mushrooms and add them to the vegetable and ham mixture.
