These 21 Day Fix Mason Jar Egg Casseroles are a perfectly portioned and portable make ahead breakfast for the 21 Day Fix! This post contains affiliate links for products I’m obsessed with.
Confession #119 – I was recently featured on a local news segment and was nervous as hell about doing live TV.
I didn’t even tell anyone it was happening until right before.
But it actually went really well. I always say I’m most comfortable in the kitchen…and apparently a studio kitchen on TV is no different.
And if I can be totally honest, it fulfilled a crazy old dream of this girl’s…dating back to watching Julia Child with my grandmother in the 80s.
I always wanted to have my own cooking show.
My grandma used to give me a pot, some uncooked spaghetti and a wooden spoons and I used to not only pretend to cook, I would narrate what I was doing to an imaginary audience.
This was pre-food network, people.
Anyway, I never actually thought this dream would happen or even tried to pursue it…so it was more of a daydream than anything. And while doing a quick cooking demo on the local news might be as close as I come to a real cooking show, I’m still counting it as dream fulfilled! When it’s your dream, you can do that, right?
Anyway, if you didn’t see it live, I demonstrated two make ahead breakfast ideas – my 21 Day Fix Baked Oatmeal Jars and these adorable and delicious egg casseroles.
I love a good breakfast casserole, but always have trouble sticking to just one piece. I mean…bacon, egg and cheese anything is just so freaking good.
That’s why portioning these out into cute little mason jars BEFORE cooking helps you stay on track, plus they are perfectly portable without dirtying a single additional plate or container.
I used cauliflower rice as the base of my casserole, and followed a similar layering technique as I did in my 21 Day Fix Crock Pot Breakfast Casserole, but I only did one layer of all the ingredients. If you still aren’t sure about cauliflower rice, you could easily add roasted potatoes or sweet potatoes to the bottom of your jar. Still on plan! But I’m always looking for ways to save yellows and add in more veggies.
And I used turkey bacon, but these would be really yummy with breakfast sausage if that’s your thing! One thing I will caution – the egg mixture tends to stick to the mason jars, so you really need to spray them well before filling. Otherwise, this is such an easy breakfast to prep ahead and even have your kids help you make before a busy week!
You can use any size mason jar for this, but I love these 16 oz wide mouth jars the best!
I can’t wait to make more Mason Jar breakfasts and share them with you all!

Kori says
Cauliflower rice?
Nancylynn says
Yup! It’s essentially just shredded cauliflower – you can buy it premade this way or just pulse your raw florets in a food processor!
Jocelyn says
Sounds great! Do you think this would work with frozen cauliflower rice? If so, should I cook it first, or thaw it, or just keep it frozen? Thanks! Can’t wait to try this!
Nancylynn says
I would thaw it first, but you can keep it raw!
Erin says
You Cook the turkey bacon first right?
Nancylynn says
yes!!
Erin says
Great thanks Nancy!! Making it now ?
Nancylynn says
Let me know what you think!!
Karen says
Sounds yummy! Have you tried cooking these in an Instant Pot? If how long? Covered?
Julia says
Have you ever made this in an instant pot? If so, what would you set it on and how long?
Nancylynn says
Yes! Five minutes on high pressure and a ten min natural release! I cook the bacon on saute first!
Shawn says
Wondering if these can be done in the microwave?
Nancylynn says
Sure!
Amanda says
I have 8 oz all jars. Will that be okay?
Nancylynn says
I think so!
Tina Pratti says
You were on TV with my cousin Eve. Isn’t she the sweetest person ever.
Nancylynn says
Yes! I love that girl! <3
Holly White says
What other containers could be used instead of mason jars?
Nancylynn says
I love the small pyrex ramekins!
Rebecca cochell says
wish that you would put the net carbs fat and protein amounts
★★★★★
Nancylynn says
Hi Rebecca- I have been thinking of adding them, I just don’t always find the online calculators to be all that reliable. I will keep looking!
Kristen Scala says
Do you think that if made on a Sunday that these will last until Friday? I like to meal prep for the week.
Nancylynn says
I think they would! They also freeze well!
Liz says
How long would you microwave these if you do not cook them ahead of time?
Nancylynn says
I’m sorry I didn’t see this- just a minute or two!
Titeta D Foote says
Hi,I wanted to see if you could use another base
Nancylynn says
Sure! You can use potatoes or sweet potatoes…or whatever you want!
Siobhan says
Hello, could you use 8 regular eggs (so 2 eggs per mason jar) if we weren’t adding bacon or turkey sausage? Or just add more red to our total if we do use bacon or sausage? I don’t ever have XL eggs on hand.
Nancylynn says
Sure! That works fine!
Kayla says
Should you freeze them before baking?
Nancylynn says
Nope! You can bake and then freeze!
Jennifer says
How long would these stay for in the freezer?
Nancylynn says
three months
Jessica says
What size jar do you recommend for this?
Nancylynn says
These!!! (affiliate) https://amzn.to/37drAln
Mary says
Quick question, when it writes in the recipe – SCALE 1x, 2x, 3x,
Does that mean that 1x is one portion?
Because 6 eggs seem like 2 portions.
Nancylynn says
No – that is to double or triple the recipe!
Ashleigh says
If you use sweet potatoes as the base, do you cook them first before baking in the jars?
Nancylynn says
If they were riced sweet potatoes, I think you could add them raw. Any larger and I would give them a little saute first!
Annie says
I really want to make this but I keep reading that mason jars are not oven-safe! Any suggestions for something else to cook it in?
Nancylynn says
Try the original crock pot version-
