by HollyThis easy Overnight Breakfast Casserole is quick to prep in the evening and then baked up fresh and delicious in the morning! Cheese, bacon, bell peppers and green onions are layered with bread and soaked in a seasoned egg mixture. This is the perfect meal to serve on a holiday morning or for guests.
A Breakfast Casserole Known By Many Names
I have eaten this casserole on Christmas morning for as long as I can remember. My mom always made it when I was young and I looked forward to this casserole every year at Christmas Breakfast!
We have always called it wife saver but it’s also known as a strata which is basically bread and eggs with yummy add ins.
It’s great because it’s really easy to make and it’s made the night before (or at least 3-4 hours ahead of time). In the morning just put it in the oven to cook while your family is doing other fun activities (like opening stockings or egg hunting!) or even if you have a house full of guests to feed!
Cutting or Leaving the Crust
I find a lot of breakfast items are on the sweeter side like pancakes and waffles but I’m a savory girl so this is my favorite. Since we have a large family, I usually make this and a sweeter Overnight Apple Pie French Toast for my kids (or sometimes Blueberry Cream Cheese French Toast).
I think every family seems to have a slightly different version of this meal.
My mother in law adds a crunchy topping to hers (and uses brown bread) while my sister cuts off the crusts and leaves her slices whole. I always leave the crusts and cube my bread since I really can’t tell the difference and let’s face it, less work is better.
Casserole Preparation & Add-ins
You can certainly add in whatever you like, ham or sausage are great in this as well! We’ve added everything from ham and asparagus to artichokes and mushrooms (pre-cook the mushrooms so they don’t get watery). Of all the versions I’ve had, this one is definitely my favorite.
It’s so easy to put together and a great way to feed breakfast to a crowd so I often make it when we have guests over! If you’re the kind of person that likes to eat breakfast for dinner, this is a super simple prep ahead meal and if you are lucky enough to have any leftovers, this is great reheated too!
Note: It’s best to take the casserole out of the fridge first thing and let it sit at room temperature for about 30 minutes. If you are cooking two pans, baking time will increase by about 20-30 minutes.

This was quite amazing. Everybody in my family loved it. I was really surprised how the bread at the bottom formed a nice “crust”.
Yay! Our family loves it so much too!
Yummy! this is the perfect weekend breakfast! I especially like casserole breakfast recipes for weekends that we have company… love this.
I agree, they’re so great to prep ahead of time!
These photos are amazing. I don’t do meat or dairy but my sister is always looking for new recipes to try on Christmas. I’m going to forward this to her asap. Thanks for sharing.
Thank you Deborah! If you do eat eggs, leaving out the meat and using a non-diary milk would be great too, this recipe is very forgiving!
This looks fantastic and I know my whole family would love it! Can’t wait to give it a try!
Thanks Kim, I can’t wait to hear how it goes!

Holly, would this Mexicans Egg Casserole work well in a Dutch Oven?
What modifications would you suggest?
Oven temperature? Duration of cooking time?
Thank you.

While I haven’t tried this particular recipe in the oven, I do make a similar one in the oven. I bake it at 350 for 1 hour (covered with foil for the first 30 minutes). I would suggest checking it for doneness after 45 minutes by inserting a knife in the center. If the knife comes out clean, the casserole is done.
Double checked my recipe but took 1 1/2 hours at 350F and center still not coming clean with knife. Any suggestions why it would not set? I used 1 cup of ham. I put both the ham and diced red pepper in a baggie with a paper towel to absorb any extra liquid before putting together. Used whole milk and extra large eggs.
Did you put this casserole in right from the fridge or did you let it sit out for a little bit?
Do you cook the bacon first?
Yes, the bacon is cooked first.
I wonder if leftovers can be frozen? I’ve a foodsaver vacuum sealer, so it can be tightly sealer.
Absolutely! That would make for a super yummy and fast breakfast another day!
Simply amazing. I love it. Thank you for all the effort made.
Built this tonigh, but had to make a few changes…
No onions, peppers or onions in the kitchen. So I opened a jar of salsa!! Also using ham not bacon. Looking forward to morning!!
Yum!! I’ve made it 3 times this week so far with different additions. I love the idea of adding salsa, thank you for sharing!
Have you tried it with bacon and sausage for a meatier casserole? Or would the sausage be to greasy?
Yes, I actually made a version with sausage (and mushrooms) this morning and it was delicious! I precooked the sausage and drained well before preparing and it wasn’t greasy at all.
This looks so easy and delicious, and all that gooey cheese is seriously dreamy!
I have been going through all this good food for awhile.There are a lot I would like to “pin” only I have no idea what I am doing lo .Please help thank you very much.
