Easy Breakfast Casserole has hash browns, ham, cheese, and eggs. This hash brown breakfast casserole can be made overnight. Perfect for a Holiday breakfast!
What makes this hash brown casserole easy?
Seriously, it took me longer to preheat my oven than it did for me to prepare this egg casserole. I used frozen hash browns, shredded cheese, and cubed ham. So, the only real prep work that I had to do was crack open the eggs.
This casserole will feed a crowd. It makes 12 portions.
It would be perfect around the holidays since you only need to spend about 5 minutes in the kitchen putting it together. Then, just let it bake.

Has anyone tried this casserole with green onions? If so, how was it?
Danielle says
I have added green onions. Enhanced the flavor a bit. Been thinking I want to try with green pepper & white onion this weekend.
Jeannette says
I use O’Brien hash browns if I have them on hand and it’s good.
Rebecca Armenta Hill says
Yes adding green onion adds a great taste to ity. My family are meat lovers a actually add Jimmy Dean sausage with the ham and I go the extra mile buy cooking bacon and crumbling it on top. I jyst loved this meal especially since I can prepare it on the night before. Pop it in the oven jump in the shower and start my day!
Jill says
Made this for holiday department meeting at school and it was raved about. I’m emailing recipe out to the whole department to share with their friends and families. The only thing I did differently was thaw hash browns and then attempted to brown a bit in skillet but didn’t get the effect I desired as far as browning, but it didn’t matter at all! I added cooked bacon and some onion powder and two extra eggs and a splash more milk. I put cheese on top too and incorporated some chives…Delicious! Salsa is a must on the side. Thank you so much for sharing this 🙂
T Lutes says
Love this dish! It has become a Christmas tradition to us. The recipe is delicious as-is, but I use a 30 oz bag of Potatoes O’Brien (the red and green pepper and onion provide color and flavor). I also sprinkle the potatoes, ham and cheese liberally with ground mustard before tossing them (it tends to clump if added to the eggs). And, I add 1/8 teaspoon cayenne pepper to the eggs. Reading the comments, I am eager to try using a combination of milk and sour cream. Thank you for this recipe!
Rebecca Buchko says
I’m adding frozen spinach (thawed) into the mix this year, should I adjust the cooking time?
Eryn says
how long will this last in the fridge?
Kara says
This is super versatile. I only had 10 eggs and 6 oz of cheese (Colby) and added cooked bacon was still great.
Gayle says
I made for Christmas brunch. It was a hit. I made no changes to the recipe! Definitely will make again!
Eryn says
how long will this stay good in the fridge?
Fran says
Very easy to assemble and my family loved it!!
Lynne says
Really good! I improvised a bit, adding a layer of defrosted frozen spinach, chopped onions and mushrooms on top of the hash browns. Also added a cup of sour cream along with the milk and eggs, resulting in a very moist casserole. Holds its shape nicely when slicing and serving.
Miller says
How well does this freeze?
Marsha Everett says
Can this be made the night before and cooked in the morning?
Carla A Devlin says
Yes, I made this Christmas eve for Christmas morning. I did use 1c sour cream and cut milk in half but followed the recipe otherwise. It was delicious and sliced and served nicely keeping its square shape. We ate it for breakfast for several days and am pretty sure it would freeze well after baking. Freezing was my plan but there was none left to try freezing.
Andrea says
Threw in some asparagus…friends and family loved it, as did I
Lynnette Post says
I use Jimmy Dean Sausage instead of ham It’s our go to weekend breakfast dish on Sundays after church.
Linda Jackson says
I never made a breakfast casserole before. For this to be my first time, I made it for my Church and it came out perfect. They are all still alive (smile).
My husband being a chef, loved it.
Thank you for a simple great recipe.
Joyce Collins says
Hi and thank you for the breakfast casserole recipe. It was quick, and as one other person mentioned, versatile. I used Potatoes O’Brian, but halved the recipe for just two old people! Added garlic powder, chopped bacon, Some chopped onion, a chopped tomato, chopped Jalapeño, topped with a sprinkle of chili paper and hot paprika for a little extra color. Served with salsa and sour cream. I appreciate this quick and nutritious recipe.
John says
Rhat sounds delicious! Thanks for sharing!
Karen Antolick says
Wonderful and too easy! We love breakfast at dinner so we made this and everyone wanted seconds. For a family of 4 we emptied the dish. I added Asian Zing to mine and my daughter used ketchup.
bernice Kube says
Turns out great every time. I from time to time substitute sausage instead of the ham.
McKenzie says
Can this be frozen? And if so, can it be frozen uncooked or does it need to be baked first? Expecting a new baby in about a week or so and need to prep some meals!
Corey Raymond says
This was super easy. I added frozen diced onions and diced red and yellow peppers and this turned out really good.
Geneva says
Very good but mine burned at 400degrees for 50 minutes. I will cook at 350 next time which is recommended in another recipe. I also added two 8 oz cans of green chilies.
Lydia says
Hi! I’m vegetarian and would like to make this recipe without the ham. Would you suggest any changes to the remaining ingredients (e.g. adjustments to how much milk, etc)
Thanks!
Mandy says
I’ve made without meat, with bacon, with sausage, with both, with added veggies, split in to 2 containers. All works. When added a lot more stuff I kind of would recommend added more eggs and a little more milk. But it’s really good. I think tastes best with the sausage but anything will be good 🙂
Jasmine says
If the recipe is cut in half will it still take an hour to bake?
Joey says
Yes it’ll take about the same amount of time if I’m like an 8×8 or 9×9
Erin Browning says
This was so good, even though I forgot the milk! Haha. Whoops!
Thomasennia says
Help Please
I am trying this for dinner tonight. I’ve shredded potatoes. Do I need to brown the potatoes before adding them at the bottom of the casserole dish before baking ?
Mandy says
Frozen hashbrowns are usually a thicker piece than you would get using a cheese grater. They are also usually blanched.
You also want to press all the excess water out.
A lot of people recommend a salad spinner after pressing.
I think if you crisped them up they would taste good.
As a chef on food network star says… “brown food tastes good!”
If I were giving you my opinion just stick with the frozen bagged potatoes.
Heather R says
Fantastic texture…. and good flavor. Plain, but in a good way. I do like to add veggies to it sometimes but we love it.
Tracy says
I agree with what some others have said, the O’Brien potatoes give it a prettier look and a little extra flavor! I would add that if you defrost the potatoes in the microwave a couple of minutes before mixing, it puffs up a little and is prettier also. Thanks for the easy delicious breakfast!
