Scrambled Egg Casserole
This scrambled egg casserole with creamy, cheesy eggs, ham, green onions, mushrooms, and a buttery breadcrumb crust is a fun twist on the classic egg bake!
I love a good breakfast casserole! Whether you are looking for a breakfast to meal prep for the week or you need to feed a crowd, there’s something for everyone here. When it came to this one, I wanted a recipe that was special enough for holidays but still easy to make. Enter: the scrambled egg casserole.
While the ingredients are similar, this casserole isn’t like your traditional breakfast casserole! Instead, it has creamy scrambled eggs that are started on the stovetop, poured into a casserole dish, topped with crunchy breadcrumbs, and finished in the oven. While I’ve included ham, green onions, and mushrooms here, you can easily swap in your favorite add-ins!
Ingredients
The full printable recipe card with measurements and instructions is found at the bottom of the post.
- Butter – Butter will help keep the eggs from sticking to the dish.
- Flour – Just a bit of all-purpose flour will help thicken the casserole.
- Milk – Milk makes these scrambled eggs ultra creamy!
- Cheddar Cheese – Some of the shredded cheddar cheese helps make this casserole extra delicious.
- Ham – Cubed ham adds a bit of extra protein.
- Green Onions – Green onions add a great flavor to this dish.
- Mushrooms – I added sliced mushrooms as my vegetable of choice.
- Eggs – Of course, you’ll need eggs!
- Breadcrumbs – You’ll need breadcrumbs to top the casserole with.
How to Make Scrambled Egg Casserole
- Preheat the oven and prep your dish. Preheat your oven to 350°F and grease your casserole dish with butter or oil so the eggs don’t stick.
- Make the sauce. Next, you’ll start on the sauce. Melt two tablespoons of butter in a saucepan, then add the flour, salt, and pepper and stir until it bubbles. Gradually stir in the milk and cook until it thickens, then remove it from the heat.
- Add the cheese. Stir the cheese into the sauce until thoroughly combined, then set it aside.
- Make the scrambled egg mixture. Melt three tablespoons of butter in a skillet over medium heat. Add the ham, mushrooms, and green onions, and sauté until the onions are softened. Pour the eggs into the pan, then stir until they begin to set. Add the cheese sauce and stir. Pour the mixture into the prepared casserole dish.
- Top with breadcrumbs. Melt the remaining three tablespoons of butter and mix with breadcrumbs. Sprinkle over the top of the casserole.
- Bake. Bake the casserole for 20 minutes or until the top is golden brown and the eggs are set. Garnish with green onions, if desired.

Egg is one of the worst things to clean off of cookware. I’ll have to look for Scrubtastic in my local store.
Hi Tara, I bought mine at Big Lots!
This is a perfect meal for me. I love my eggs 🙂 I had to laugh when I saw the kitchen sponge is in the shape of a duck, this might also encourage children to wash-up besides making the clean-up easier.
I love a good casserole. This looks great. My kids are such better eaters now and ham is their staple
A nice change to our typical egg bake when we have company over. This sounds and looks delicious.

I wanted to do scrambled eggs with cheese and bacon for Christmas morning breakfast this year. But now I think you just convinced me to change that! YUM!
That looks so good! I like when I can make something different than frozen waffles or cereal! This is MUCH heartier and would keep me and my family from getting hungry faster!
