Hashbrown breakfast casserole is perfect for feeding a crowd.
This casserole is perfect for breakfast or brunch, and would make a great recipe for Christmas morning!
While I love a good hash brown casserole with breakfast, this recipe is more of a complete meal with the addition of eggs and veggies.
How to make hash brown egg casserole
Step 1: Melt butter in a skillet and add the yellow onion and minced garlic.
Cook until onion is soft, around 10 minutes.
While the onions are cooking, go ahead and prep the bell peppers, cheese, and green onions.
Be sure not to skip grating the cheese fresh, it really makes a big difference in flavor!
I love the flavor of sharp cheddar in this casserole recipe.
Step 2: Add the thawed frozen hash browns, half of the fresh grated cheddar cheese, cooked garlic and onion, and red and green bell peppers to a large bowl.
Stir well until combined.
Step 3: Grease a large 9 by 13 baking dish and add the hash brown mixture to it. Spread out evenly.
Step 4: In a bowl, whisk together the eggs, milk, salt and pepper, and Italian seasoning.
Step 5: Pour the egg mixture evenly over the potato casserole.
Try to get it evenly to cover the whole dish.
Step 6: Top with the remaining sharp cheddar cheese and the chopped green onions.
Step 7: Bake the hash brown egg casserole at 375 degrees for one hour, until the edges are browned and the cheese is bubbly.
Serve and enjoy!
What to serve with hash brown breakfast casserole
- Fruit Salad
- Sausage, Bacon (Vegetarian versions for us!)
- with ketchup or salsa
- No Rise Cinnamon Rolls
This recipe is delicious as is, but we personally like to serve ours with ketchup.
Breakfast casserole is great for special occasions, or meal prep to have breakfast for several days in a row.
The bell peppers add a great texture to the dish, but you could definitely switch it up and use what you have on hand!
Cooked mushrooms or spinach would be great additions as well.
You can’t go wrong with a cheesy hashbrown casserole!

I used seasoned shredded hash browns and added a half cup of sour cream to the hash brown mixture before spreading in pan. Delicious!
Your additions sound delicious!
I’m making this but used the recipe as a base. It is currently in the oven!
I used stuff in the fridge that needed to be used. To start, I doubled it using shredded hash browns. My bags were only 30oz each, not 32oz. I added 12oz fresh bacon (fried); 2 diced yellow onions because I had no green onions; and fresh chopped grape tomatoes. I only had Colby jack/cheddar shredded cheese and some hatch chili shredded cheese so I used enough to get to the 6 cups needed. To the egg mixture I added fresh spinach & fresh sweet basil, pinched into small chunks. Before adding eggs to the hash browns, I added a single layer of thin zucchini slices then cooked the hash brown mixture for 15 mins as it was was very thick since I doubled it and I thought it might be a good idea to give the potatoes a head start. Once I added the eggs and extra cheese, I returned to the oven for an hour. I’ll let you know how it turned out!!
Can you make this the night before?
Can you make this recipe with shredded hash browns?
I have not tried it but I don’t see why not!
@Karen, I just made it with shredded hash browns. Looks fine. I am going to take it to an office party tomorrow, but I’m sure it will taste just like the version with cubed potatoes.
