Best Egg Casserole with Hash Browns

I am always on the lookout for the best egg casserole recipes. Breakfast casserole recipes are my favorite brunch dishes, and I’ve been known to make them for dinner when I get tired of the same old chicken recipes we normally have.

My cheesy egg casserole is something I make every year and adding hash browns just seemed like a natural progression. One of my readers told me about her NO FAIL egg casserole with sausage and cheese and hash browns, so I decided I NEEDED to recreate it.

What’s in a hash brown breakfast casserole?

This easy egg casserole has a few different layers:

  • Hash browns: I used about half of a 30 ounce package of frozen hash browns.
  • Sausage – you can use bulk sausage or remove the casings from breakfast links. You can even substitute bacon.
  • Eggs – 6 large Eggland’s Best Eggs went into this casserole.
  • Cheese – I used 1 1/2 cups cheddar cheese that I shredded myself.
  • Spices – A teaspoon onion powder along with garlic, salt, pepper and dried mustard add tons of flavor.

I added sausage to my egg casserole. You can skip the sausage if you want, or use bacon! Just brown up some bulk breakfast sausage (if you only have links, remove the casings).

Once the sausage is browned and drained, sprinkle on top of the hash browns.

Then top it with shredded cheddar cheese (or you could also use Monterey Jack or Mozzarella).

Pour the egg mixture over the top in the casserole dish. Cover, bake for about an hour, and then remove the foil cover about halfway through baking, about 20 minutes.

Once the center is set, you will have the perfect hashbrown breakfast casserole. It’s the best brunch recipe for Christmas morning, but we also eat this for dinner! It’s great with a side salad.

  1. I have cooked many different breakfast casseroles. This is my families favorite. I use a bag of cheese on top. Delicious!!

  2. What kind of salt do you use? I know that 1 tsp kosher salt is completely different than 1 tsp table salt. Don’t want to accidentally make it too salty. Thanks!!
