Breakfast Casserole Tips For Success
Make ahead: You can easily make this casserole the night before and bake in the morning. Just cover in the fridge and take out while your oven is preheating. You may need to increase the baking time by 10-15 minutes.
Baking Tip: This casserole is done when the edges are set and lightly brown and the center only jiggles slightly. Make sure there is no “watery” eggs in the center before removing from the oven.
Storage: Cover the entire casserole with foil or a lid to your baking dish and refrigerate for up to 3 days.
Reheat: Reheat in the microwave.
Freeze: This casserole can be frozen. First bake your breakfast casserole and once it has completely cooled, place in an airtight container or ziplock bag. When ready to warm up, place in oven and bake at 350 degrees until warmed through about 20 to 25 minutes.

Look at all that cheesy goodness! Doesn’t it make you want to have a piece right now?! Well, what are you waiting for?

Could this recipe be halved for a 8×8 baking dish?
Sure! I do this all the time!
Could you mix this together and cook the next morning
Yes I think that would work – try out overnight breakfast casserole too! https://www.allthingsmamma.com/overnight-breakfast-casserole/
It freezes well. It’s a great thing to make on Sunday and then cut into portions for the week.
wonderful!! easy to make!!
Made this breakfast casserole, we loved it! It’s simple to make and delicious.
I have made this recipe so many times. Making it right now for my Sunday School class. I generally always add chopped onions and chopped green chilis to give it a little kick. Good recipe!
Thoroughly enjoyed this casserole – very quick and easy, and totally yummy. I did toast the hash browns before cooking, but I don’t know if it made a difference or not. Thanks!!
I made this today. Super easy baked up perfectly. I think this is a recipe that is very versatile, add peppers or onions, I added bacon bits because I had some to use up. Delicious.
Can the Simply potatoes that are not frozen work too?
I have made this several times for Sunday Brunch and everyone has enjoyed the simplicity of the casserole. Many of the guests were glad there was no peppers and onions added. (1 change, I use dehydrated hashbrown potatoes)
When you used the dehydrated kind, did you rehydrate them first? Or throw them in still dried? And how did it turn out when you are it? Did you change anything else? Thank you!
I made this the night before for a Christmas breakfast for several people. It was easy to make and baked up very nice. It was a little dry but otherwise everyone loved it and asked for the recipe. Next time maybe will add a little more milk. Thank you for a very easy go to breakfast casserole.
The 15oz for the hashbrowns….do I use half of a 15oz bag? Or am I using half of a 30 oz bag of hashbrowns? How much (in oz) go into the recipe??
Half of the bag.
Half of what size bag!???!
Hey Jamie! The recipe calls for 15 oz. The bag is 30 oz. Hope this helps!
I thought the same thing, so I used enough to put in the bottom of the dish. Seems 1/2 of 30 oz bag was good.
Awesome
First timer! Perfect timing in my 9 3/4″ square dish using 1 less egg & 1/3c less milk. I added sauteed onion just cause I like it!
How many does this serve?
12 squares – but sometimes we eat more than 1! 🙂
My family enjoyed this breakfast dish very much. They said it was a keeper.
Yay! It’s definitely a family approved recipe!
I decreased the milk by one and increased the eggs by two. It was perfect!
GREAT!!!
I have a similar recipe but it calls for crescent rolls. I line the bottom of my pan with the rolls and add the other ingredients. After it comes out of the oven and I serve it, I make gravy to top it with. Yum yum!
I have one that we love too! https://www.allthingsmamma.com/overnight-breakfast-casserole/
Absolutely wonderful!!! I didn’t change anything, only added onions and yellow and red peppers. This was so good that my hubby is asking for it again this weekend.
Good for First casseroles. It Was Delicious. Added greeb bell pepper for good flavor
I made this tonight for dinner and it was a HIT! Even for my picky little. She gobbled it up. No left overs to find. Made garlic bread to go with it and it topped it off for sure! Great recipe.
So glad everyone enjoyed this recipe!
I just want to make sure, you do not have to defrost the hash browns before baking, correct?
That is correct!
Can you use the fresh shredded potatoes?
I’ve used the fresh, shredded potatoes in the dairy aisle before – but not homemade. I would thikn it would work but I haven’t tried it!
Could you use a slow cooker to prepare, if so what temperature and how long? Also some warm tortillas would represent this so well don’t ya’ll think? Jalapenos for that Texas flare!
Definitely, stay tuned! We may have a recipe for this in the works 🙂
