Mini Freezable Breakfast Casserole Bites Recipe
Looking for a freezable breakfast casserole? This recipe could go two ways. You could make this dish the next time you have guests over for brunch, especially since the mixture could be made and put into the muffin cups in advance. Or you could bake a big double batch this weekend and freeze them for those busy weekday mornings.

How to Make These Freezable Breakfast Casserole Bites
If you decide to freeze them with the foil muffin holders still on then you’ll be able to pop them right into the toaster oven. Or if you take the muffin holders off before freezing they'll be microwave-ready. Either way, I do recommend taking them out of the freezer the night before so they can thaw out overnight.
Whatever you decide to do with this recipe though I don’t think you’ll be disappointed…it’s hard to go wrong with breakfast food!
How to Make Mini Eggs Casserole Without Bread
If for whatever reason you’d like to leave the bread out of this recipe, no problem! It’s easy to make these eggs casserole without bread by simply substituting with something like shredded hash browns, or even spinach mixed in with the eggs for added protein and greens.
If you plan on omitting the bread, simply skip step #3 in the recipe below. You might also have better luck with a greased silicone mini cupcake tray if you're not putting the bread in the bottom.
If you plan on incorporating vegetables like spinach, asparagus or peppers into the recipe, be sure to gently steam or sauté them ahead of time to remove a bit of the moisture so the egg bites don’t crumble!







cythia says
are these in regular muffin pans or mini? I want to do mini do to the amount of ppl we are having.
Amy Taylor (comment moderator) says
Hi. You can do minis but would need to reduce the cooking time.
Jess says
I love these! But just curious, all my mix ins end up on the top....it's there any way to keep them mixed throughout?
Bri says
I stumbled across your website and I am so thankful I did! Not only
Do you have wonderful advice for packing school lunches; I've tried them and my kids are coming home with empty lunch boxes! #momonamission. I tried this recipe for breakfast and my daughter who dislikes scrambled eggs enjoys this dish. I was skeptical about adding the bread assuming it might get soggy, but mixed with the eggs/cheese it gives it a nice flavor and didn't lose form. Wonderful recipe!

Could silicone cupcake liners be used instead of foil lined? I have a hard time finding non-paper lined foil cupcake liners in my area. They all seem to have paper on the inside.
Amy Taylor (comment moderator) says
Sure, silicone will work.
Eileen says
I make this in a 9 x 13 baking dish normally, but am thinking of making the muffins for a track meet this weekend. Do you spray the muffin holders/disposable cups with Pam or anything to keep it from sticking to it???
Amy Taylor (comment moderator) says
Hi there. I use a Misto spray bottle with avocado oil. We avoid commercial sprays because they are full of not so great ingredients (propellants).
LAB says
Could I use a little cooked shredded hash browns in the bottom instead of the bread.?
Amy Taylor (comment moderator) says
Yes! :)
Onexda says
Could I make this in a baking dish?
Amy Taylor (comment moderator) says
Yes, but you will likely need to adjust the cooking time.
Roxanne M Johnson says
Can these be prepared the night before and baked the next morning?
100 Days Admin says
I would suggest making them the night before, placing them in the fridge, and then reheating them the next morning. They will turn out just as good. - Nicole
Nic C says
I've made these a number of times but recently they have started to sink in the middle, I can't think what I'm doing differently?
Amy Taylor (comment moderator) says
Hi there. Mine sink sometimes, too. I started adding a little baking powder to keep them fluffy. :)
Emma says
Amy-how much baking powder would you use? Thanks! Emma
Amy Taylor (comment moderator) says
About a 1/2 tsp. :)
jashon says
Is Very Good Food Thank you
Amy D. says
Hello, how long/how do you heat in a toaster oven after freezing?
Amy Taylor (comment moderator) says
Hello. I defrost them overnight and heat them until warmed through which is between 5 and 7 minutes in my toaster oven.
Alina says
Are these full size muffin pans and liners or the mini-size? I want to make these for a brunch and look forward to serving them warm. Thanks for the input. :-)
Amy Taylor (comment moderator) says
Hi Alina. They are standard size.
Amy says
Are FOIL muffin liners preferred?
Paper ones alright to use?
Amy Taylor (comment moderator) says
Hi. Paper will work, too, but they may stick a bit more.
amanda says
These were so easy to make and very yummy!!!
Audrey says
My kids and I loved this recipe! And it makes wonderful after school snacks.
Amanda77kr says
Made these yesterday and they were delicious! I don't like meat so made half without bacon, and the casseroles fell after cooling off. Still tasted fine, they were just shrunken. Definitely gonna repeat and use a Kickstarter patty in mine next time (it's a locally produced breakfast patty made with black beans and spices).
Kathy says
silicone muffin pan, no liners
no bread
add veggies like asparagus, tomato, onion,jalepeno or any other choppable thing
saute veggies first
let cool, pop them out, bag them up
easy easy
Carrie says
I used the silicone cupcake liners and they worked beautifully! No spraying necessary, and they popped right out .
Jim says
I love this recipe . have used it for breakfast.. brunch and for dinner .. easy to make . its fun when you have house guest do it ahead of time . serve with fresh fruit and such . you got breakfast in no time and easy clean up
Jane says
I would love to see nutrition info for the recipes
Ciera says
Agreed!
Ciera says
And serving size, too!
100 Days Admin says
We now provide that information on the recipe. :) - Nicole
Nora says
Made these yesterday with spinach, onions, and pepper jack cheese. They were yummy!
sharon says
Did you saute the veggies first? And did you mix the veggies with egg mixture or layered veggies ontop?
andrea bennett says
I do it both ways. Ive used raw veggies and sauteed. Just depends on what flavoring you prefer. Definitely cook the meat first.
denise rogers says
Did you use fresh spinach and sautee or cooked spinach?
Kelly says
I just made these with the foil liners and they stuck to the liner like crazy!!! What am I doing wrong?!?!?!?
Amy Taylor (comment moderator) says
Hi Kelly. I sometimes do a light mist of coconut or avocado oil which helps.
Carrie says
I used the silicone cupcake liners and they worked beautifully! No spraying necessary, and they popped right out .
Ginette moore says
once frozen, how are they cooked? Toaster oven and microwave instructions would be great. Thank you!
Ginette moore says
I found the answer to my question in older comments. Thank you though!
Milena says
Yummmm!!! How long you can store it in the refrigerator?
Amy Taylor (comment moderator) says
Hello Milena. I'd say 3 days. I would freeze them if you wish to store them for longer.
Holly says
One of my favorite breakfasts! Perfect for bringing to a pot luck brunch. I've never made with bread, but I like to use either hash browns or crescent rolls as a crust. Makes a great breakfast sandwich on a toasted bagel or english muffin with some spinach and bacon.
Terrie says
They are delicious and easy, but mine fell and ar.e really hard to get out of the paper lining
Deana says
My daughter and I made these for a quick breakfast while my husband was out of town. We used breakfast turkey sausage. It did need a dab of ketchup but they were really good!! And my daughter liked them a lot!!
Ann Marks says
These are awesome! I added some red pepper and mushrooms. Turned out great. I am at 6500 ft and temp and cooking time worked for me. Thanks so much for the idea.
Angela @ Food Angel says
I make something similar, but have never heard of adding bread- interesting! I usually make them without any grains or anything, but occasionally add a crust, similar to quiche. I love mine with lots of veggies! I actually packed a bunch of these along with our toaster oven for our last trip. Heated them up in our hotel room with some muffins and made for a great breakfast!
Elaine Maier says
My husband loves these. We have different work schedules and he doesn't like to cook so I freeze them and he can have them when he is ready for breakfast.
Renee says
Anyone try it dairy free. My kids don't like the imitation cheese.
Karen says
i used to make these when I was nursing my MSPI kiddos and I just left the cheese out and used almond or rice milk and they were good. I actually forgot for awhile after I could eat cheese again to add it.
Alice says
If you want to create less waste you can easily oil the pan and bake without the liners. Mine came out easily and I did a little soak of the tin after.
Ann says
Great idea! It's nice to have the foil liners if you want to freeze some, keeps the portions together.
Ashley says
These sound delicious! We plan to make them on a Thanksgiving morning, but do not have the foil muffin cups. Would silicone ones work for these?
Thanks for sharing the recipe!!
Amy Taylor (comment moderator) says
Hi Ashley. Sorry that we often can't answer in real time. How did they turn out?
Susie henslee says
I just made them in silicone cups and they are perfect! I baked them for 3 minutes longer. They fell right out of the cups. Great recipe, thank you!
Kim says
Love these!! They took a lot longer to bake than the recipe called for....30 minutes at 350 for me (and I'm not high altitude).
Tebecca says
Why foil liners and not paper ones?
AnnieM says
I tried it with the paper ones and they did not peel off nicely....definitely using foil next time.
Amy Taylor (comment moderator) says
Hi there. You can use paper ones if you like but they tend to stick a little more. ~Amy
Carrie says
Forgo paper or foil all together and use silicone. I used the silicone cupcake liners and they worked beautifully! No spraying necessary, and they popped right out .
Debbie says
This recipe could be tweaked in many ways I would think.
Wouldn't tortilla's be ok to use instead of bread? Adding rotel or picante'or any flavoring you desire?
Great idea....will have to try for those busy mornings like Christmas morning or Easter .....quick and ready to go!
Thank you!
Amy Taylor (comment moderator) says
Hi Debbie. It is a flexible recipe. We've not tried to use tortillas with it. Let us know if you do. :)
maria says
i use spagethi in place of bread and it is delich
Morgan says
Love it! I didn't have whole wheat bread on hand (btw, what kind do you prefer if it's store bought?) so I used some left over quinoa. Fabulous. Another great recipe!
Jesiqua says
I just made these and they are delicious! I will be making another big batch to freeze. I eat breakfast at work in the morning, so these are perfect!
Alicia Silva says
What are the instructions for heating the mini casseroles after they have been frozen?
Assistant to 100 Days (Amy) says
Hello Alicia. I defrost in the fridge overnight, cover loosely with foil and reheat at 350 until heated through, about 10 minutes. ~Amy
Rebeca says
I made these with paper liners and they deflated. They are pretty small. Is this why?
Assistant to 100 Days (Amy) says
Hi Rebecca. You know, I'm not sure about the paper contributing to the shrinking. Mine always shrink a bit, too, even in silicone. ~Amy
