Gather your ingredients. Preheat oven to 350 degrees F. Grease a 9×13 baking dish.
Arrange 8 precooked frozen hash brown patties in the dish, in a single layer.
Sprinkle 1 cup shredded sharp cheddar cheese, 1 cup shredded Monterey Jack cheese, 1 & 1/2 cups diced ham, and 2 diced scallions evenly over the top of the hash browns.

Make in Advance and Storage
You can prep and serve this hash brown casserole right away, assemble it the night before, or freeze for later.
- Leftovers: cool completely, then store in an airtight container in the fridge for up to 3 days.
- Make it ahead of time: want to prep this the night before serving? No problem. Simply assemble as you would up to pouring the eggs over the hash browns. Then cover tightly with plastic wrap and refrigerate up to 24 hours in advance. Remove from the fridge when the oven is preheating and add an extra 10-15 minutes to the total baking time.
- Freeze for later: bake in a freezer-safe pan (like a foil disposable pan) and cool completely. Wrap well in plastic and again in foil and freeze for up to 2 months. Thaw overnight in the fridge, then cook at 350 degrees F for about 30 minutes until warmed through.
What to Serve with Egg Casserole
I recommend serving this with Roasted Asparagus or Cucumber Tomato Salad to round out the meal. Delicious!

Excellent egg casserole! Will definitely make again.
Family loved it
Really good! I added two extra eggs so I added about 5 minutes cooking time. I don’t love eggs and I love hashbrowns – this was the perfect mix! Added spinach as the veggie which was perfect.
I’ve made this a bunch of times and it’s
a hit! Expecting a baby in the next few months and want to prep for post partum. Would you suggest preparing and freezing without baking? Or bake then freeze
Hi Charlotte! That information is included in the article at the bottom. Congrats on the baby!
This recipe was terrific! I don’t normally comment on recipes but I’ve got to say, Bravo Any! This recipe rocks!
Can I use 1% milk or does it have to be whole milk?
Whole milk is ideal. I wouldn’t recommend using less than 2% to ensure the custard is thick enough and cooks properly.
This egg bake is so versatile and delicious.
I have made a few different versions. We like to saute mushrooms and/or breakfast sausage and then cut into small bites and add on top of the potatoes. I also finely chop onion and add it for more flavor not that it’s not perfect already.
Thank you Amy, this is another of your winning recipes! Up next will be your cashew chicken!
I made this for our breakfast after Christmas Day gathering and it was a huge hit! Shared the recipe with four family members at their request.
I was able to put it together the night before and bake in the morning. This will be something I make again and again. Thanks 😊
If I’m going to switch out the ham for ground sausage, do I need to cook the sausage first or just throw it in raw and let it cook with everything else’s
It needs to be cooked first
This is a winner! We have chickens and this recipe not only uses up some of our excess eggs but is so tasty! Many times we have breakfast for dinner and this recipe is used frequently. Thank you, Amy.
This is currently baking, it was easy to make and I can’t wait to taste it. My problem was the hash browns I bought were too big to line up in a single layer, so I had no choice but to overlap the ends. I could have softened them in the microwave or air fryer but the directions said to use frozen and I didn’t see the note about assembling ahead of time. Next time I will use tater tots. I’m sure it will come out great, and I’ll let you know!
This came out so good, the size of the hash browns didn’t even matter. I’m making another one with sausage and mushrooms. Delicious!
I cut this recipe in half, cooked peppers, onions and fresh mushrooms with the 1/2 lb sausage. It was excellent and I would definitely make it again. By the way, it also reheated well!
Made this dish on Christmas morning. l halved the recipe (just my husband, son and me) and added bacon instead of ham. It cooked beautifully and the egg seeped to the bottom and actually made a nice sort of crispy crust underneath the hashbrowns. Yummy!
I did kielbasa with onions instead of ham. Came out delicious, thank you for the awesome recipe.
I made this today for a brunch and it was a hit! I made it exactly as the recipe says except I added cooked bacon as well as the ham. Everyone wanted the recipe. This is 10/10! Easy and delicious!
Do you cook the hashbrowns a little before adding all Ingredients? Or can you. To maybe try to prevent sogginess? Haven’t made it yet, but want to Christmas mornin.
I don’t cook the hash browns first – they go right into the pan frozen, eliminating an extra step. But you definitely can.
I love this recipie, but my bake always takes much longer to get the center to set. How can I prevent this? I usually have to cook with the foil on for almost double the time.
Hi Megan! Sorry you’re having issues. I have made this so many times with perfect results, so I can’t say. Are you sure you’re cooking it at the right temperature? Not adding more liquid than is called for? Baking with foil for 25 minutes and then baking without the foil for another 20 minutes?
I really enjoyed this casserole! It was easy and had ingredients that I keep on hand.
For the meat I used a combination of ham and cooked, crumbled bacon, used whatever cheeses I had on hand, and it turned out great!
Thanks for sharing the recipe!
This was very good and easy to make.
Thank you
This was a BIG hit in my house! Only thing I did different was use hot Jimmy Dean sausage instead of ham. I served it for dinner with steamed broccoli and fruit salad.
This is a winner. I made it with bacon. Easy and delicious!!
Absolutely delicious and even better the next day
Can you make this in a crockpot/slow cooker by chance? My oven is broken and had grabbed all the ingredients for this.
Hi Joanne – I’ve never tested this recipe in a crockpot
Such a delicious easy recipe. It came out perfect and flavorful.
I have made this breakfast casserole for several different occasions and everyone absolutely loves it. I however have always used turkey sausage instead of ham and I also include chopped green chilies for extra flavor. It’s simple and delicious!!!
My daughter is a vegetarian so I sauteed mushrooms, green pepper and onions. Everyone enjoyed it. I love how easy it is to prepare!
So good! Kids loved it – even the picky 4 year old! Only modifications: all cheddar, bacon instead of ham, and didn’t have scallions. Definitely adding to the dinner rotation. Thanks for the recipe!
Great recipe! I bake hash brown patties in the pan for 15 minutes then add the egg mixture and cook for additional 25(covered). Then add an additional 5-10 minutes uncovered.That makes the bottom more crispy.
This was a great recipe, quick to fix and delicious. My husband and I enjoyed the meal very much with some cut up oranges, pears and my daughter in law’s Donut peaches!
Easy to do. Used browned turkey sausage added sautéed onions/mushrooms (make sure you sautéed them first or you’ll have a wet casserole). Put it all together the night before (including custard). Will need to cook a bit longer out of the fridge but it came out great. Thanks for sharing!
This was so good & easy to make! I did half and half on the ham & sausage crumbles. And topped with crispy bacon crumbles. Omg. You’ve made me a workplace hero :)
If I’m making this the night before, do I actually pour the eggs over the hashbrowns or wait until the morning?
Hi Rachel – all the information is included in the article below the printable recipe card. Enjoy!
I made this for a group at our lodge and it got a big thumbs up. It’s super easy and quick to put together.
I used turkey bacon instead of ham and cauliflower hashbrowns instead of regular hashbrowns, otherwise follow the recipe exactly. Yummy casserole and perfect for company!
We literally eat this once a month for over a year. It’s a family favorite!! Probably my most used recipe.
I made this recipe many times now. I tried putting a little extra amounts of ingredients and it didn’t taste as good as just following your measurement. Great recipe.
Everyone seemed really like this! Just needed a bit more in the oven.
Love this ! My fav I make every other week for family and at Christmas! I do cook it 15 min longer in my oven .
I don’t know if I doing this right. When I go to make this and follow the instructions and ingredients, once it has been in the oven for the first 25 minutes with the foil, after the foil gets removed, the eggs still look runny and not cooked all the way through, then again without the foil for the last 20 minutes, the eggs jiggle and don’t look cooked. I don’t know what I am doing wrong.
Hi Rebecca – I’ve made this countless times and it always comes out perfectly. It sounds like either you might be adding in too much liquid or your oven is off.
So easy and delicious! I have to make 3 every time, because my 3 guys fight over it!
Easy and delicious. It’s become a go-to on our weekends with the kids.
My family loves this recipe! It’s very easy to make, and it has such a great flavor to it. It helps that I usually have most of the ingredients on hand so it’s an easygo to for us.
I love this recipe. It’s really easy to make and it’s a crowd favorite when we do breakfast potlucks. Thank you!!
I made this recipe for Christmas morning. I used 1/2 cup of butter milk and 1/2 cup of unsweetened almond milk, added 1/2 of chopped red bell pepper and subbed Neese’s sausage for the ham. I was delicious!
OMG! You are so fortunate to have Neese’s sausage. That is the best! We don’t have it in Maryland.
This is such a great recipe. I add blanched broccoli sometimes. My family loves it for brunch.
I love this recipe. I make 2. One with cooked sausage and one with green chiles for family Christmas Eve brunch
I have made this a handful of times and my husband and boys love it! (And they don’t typically care for egg bakes.) It’s our go to for Christmas morning! I throw everything together the night before and put in the oven while opening Santa presents. So easy and yummy!! I also substitute ground sausage for the ham.
I’ve made this twice but substitute I pound of cooked sausage for the ham,., it’s delicious !
I love this casserole and serve it with fresh fruit and cinnamon rolls. I have made it using fire roasted green chilies, chicken and cilantro for a dinner casserole. It’s especially easy using the hash brown patties.
Incredible. Also good with diced hash browns and bacon
My picky eater loved it!
