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.

I halved the recipe and made it as written. It served 4 adults with leftovers. Delicious! I love the trifecta of fast, easy, and good. Will definitely make again. Thank you!
I doubled the batch and served it in a chafing pan for Bosses day at work today. Everyone has raved how good it was. Now I’m sharing the recipe and they will know how easy it was:)
Made it the night before and I used Jimmy Deans precooked breakfast meat mix with extra cubed ham.
I used 1/1 and 1/2 an the eggs did not come out fluffy. I always use 1/2 and 1/2 in scrambled eggs and they are delicious. Could this be the reason the eggs did not set up properly?
excellent flavor and so easy to make
Simple and easy. As others, I halved the recipe and also added red peppers, a dash of dried mustard and a small amount of onion flakes. I did use ham, but will try again with sausage and/or bacon. Thank you.
Easy and delicious.
Can you substitute with cubed hash browns instead of shredded?
This is a super easy, super delicious recipe. I fed 6 adults and had leftovers to spare. The only thing I did different was add green onions (personal preference). I wondered about browning the hash browns but I ran out of time, you absolutely do not need to brown them. Just follow the directions. This is a keeper. Thank you!
I use hot sausage .red peppers and Spanish onion it is delicious
Yum! My favorite breakfast ever! It’s a delicious lunch too! I love adding bacon. Mmm… so good!
This is the best and the easiest breakfast casserole. We are also “breakfast for dinner” people so it makes a fantastic busy night dinner. I make it the night before and pull it out of the fridge in time for dinner the next day. I also add whatever diced vegetables I have around, a little hot sauce, or a variation on the cheese. We make it again and again
Can you make this the night before
I made it the day before and it worked well. I kept the egg mixture separate until just before baking.
This is soooo good. I too added onions, bell pepper and Jimmy Dean sausage. A full YUMMY!
Awesome recipe —- definitely a keeper! Easy, fast and delicious! As someone suggested above, I added onion, red and green pepper, used sausage rather than ham, and also halved the recipe, which was plenty for four healthy appetites with leftovers. Loved by all! Appreciate the great comments from all!
Can I leave out the hash browns?
If you leave out the hash browns, you have quiche 🙂
After mixing all the ingredients can you freeze it are should you cook it first then freeze it are can you not freeze it at all
I make and freeze this unbaked to take to the beach every summer for the first mornings breakfast. My whole family love this casserole.
I also substitute jimmy dean precooked sausage crumbles for the ham.
where do you find the Jimmy dean pre cooked sausage crumbs at the store guess in the frozen dept, correct
find it in the fridge section near the raw bacon and sausage
How long do you cook this after it is frozen?
Hey Mary, do you just thaw and bake as directed? Thanks!!
Delicious and easy breakfast casserole. Not too bad calorie-wise either.
My go to recipe. Works out great. I’ve also done with with bacon insteadve ham.
Did you cook the bacon first or just cut up raw bacon?
Cook it first
I halved the recipe, and it still turned out great! I used gruyere cheese and substituted half of the hash browns with riced cauliflower. Took the advice of another reviewer and browned the hash browns and cauliflower a little and added a tbsp of onion powder before mixing it with the ham and cheese. Also added a pinch of cayenne to the egg mix. I would have totally gone with the potatoes O’Brien others have mentioned, but that’s a hard no from my husband. It’s good enough for me that I could sneak in the cauliflower!
This is great! I made 2/3 of a recipe. I used bacon instead of ham. I also put in 2 chopped apples instead of the vegetables. Oh and 1/4 cup of maple syrup to sweeten it. I left out the salt and pepper. Thanks for the recipe. It was delicious.
When halting the recipe, do you half the time cooking too?
I added 1 tsp ground mustard and 1/2 tsp black pepper. I also added onion, green onion, and red pepper. This recipe is delicious! Finally a breakfast casserole that the whole family loved. Thank you!
I wish I saw this comment earlier, will try this next tine.
Whooping doo!
I have made this several times and everytime I visit my best friend, they made sure they have the ingredients so I can make it for them!!!
Did you cook the onion and pepper first?
Yum!! My family loved this! Everyone had an idea what would be good added to it. Next time, and the next time and the next time! Great breakfast basic…now go crazy enhancing it. Me, I liked it just the way this recipe worked up.
