I love a good breakfast casserole! Whether you are looking for a breakfast to meal prep for the week or you are needing 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, then 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 if you like!

Ingredients

  • 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 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

  1. Preheat the oven and prep your dish. First, you’ll want to preheat your oven to 350 F and grease your casserole dish with butter or oil so that the eggs don’t stick to it.
  2. 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 it until it starts to bubble. Gradually stir in the milk and cook until it thickens, then remove it from the heat.
  3. Add the cheese. Stir the cheese into the sauce until fully combined, then set it aside.
  4. Make the scrambled egg mixture. Melt 3 tablespoons butter in a skillet over medium heat. Add the ham, mushrooms and green onion and sauté until onions are softened. Pour the eggs into the pan, then stir until they begin to set. Add in cheese sauce and stir. Pour mixture into prepared casserole dish.
  5. Top with breadcrumbs. Melt the remaining 3 tablespoons butter and mix with breadcrumbs. Sprinkle over top of casserole.
  6. Bake. Bake the casserole for 20 minutes or until top is golden brown and eggs are set. Garnish with green onions, if desired.

      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.

    2. Egg is one of the worst things to clean off of cookware. I’ll have to look for Scrubtastic in my local store.
