This Cheesy Broccoli Breakfast Casserole is a breakfast casserole recipe made with hashbrowns, broccoli, ham, eggs, milk, and plenty of melty cheese, baked together into one warm and hearty dish. It’s the kind of easy breakfast you can just mix, bake, and serve without stress, which makes busy mornings so much smoother.
I love making this for holiday breakfasts, and it works really well for brunch potlucks or meal prep for the week because it reheats so nicely and keeps you full for hours.
If you want to round out the meal, this casserole goes really well with a simple fruit salad or a warm side of toast or muffins for a complete breakfast spread.

Important Recipe Notes
- Make sure your frozen shredded hashbrowns are fully thawed before mixing. This helps everything cook evenly and avoids extra moisture in the casserole.
- If your broccoli or hashbrowns seem watery, gently pat them dry with a paper towel before adding to the dish so the casserole doesn’t turn soggy.
- Keep the ham, broccoli, and green onions in small, bite-sized pieces so every slice of the casserole has a little bit of everything.
- The center should be fully set and not jiggly. If needed, bake a few extra minutes after removing the foil.
- Let it rest before slicing: Allow the casserole to sit for about 5–10 minutes after baking so it firms up and cuts neatly.
- For extra flavor, you can mix a little cheese into the casserole and also sprinkle some on top for a golden, cheesy crust.
