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!

  1. 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?

  2. 5 stars
    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!

  3. 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.

  4. 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???

      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).

      1. 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

    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?

      Hello. I defrost them overnight and heat them until warmed through which is between 5 and 7 minutes in my toaster oven.

  6. 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. :-)

    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).

  8. 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

  9. I used the silicone cupcake liners and they worked beautifully! No spraying necessary, and they popped right out .

  10. 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

        I do it both ways. Ive used raw veggies and sauteed. Just depends on what flavoring you prefer. Definitely cook the meat first.

  11. I just made these with the foil liners and they stuck to the liner like crazy!!! What am I doing wrong?!?!?!?

    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.

  13. 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!!

  14. 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.

  15. 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!

    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.

    1. 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.

  17. 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.

  18. 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!!

    1. 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!

  19. 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).

    1. 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 .

  20. 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!

      Hi Debbie. It is a flexible recipe. We’ve not tried to use tortillas with it. Let us know if you do. :)

    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!

  22. 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!

      Hello Alicia. I defrost in the fridge overnight, cover loosely with foil and reheat at 350 until heated through, about 10 minutes. ~Amy

      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
