Aaahhhh make-ahead breakfast casseroles, my new best friend!
Hey, they're not just for Christmas any more guys! Or maybe that was just me. For some reason the only time I whipped out these tasty casseroles was over Christmas/New Year. I have no idea why.
Possibly it is because that is when I was so busy shopping, wrapping, shuttling kids around, partying, and so many other things, breakfast was something I didn't want to think about. I just wanted to be able to heat and serve.
So I seriously have not made one of these casseroles in years!
Then Kevin started working nights (oh don't even get me started on how much that fact really drives me crazy) and our sleeping and meal schedule just kind of went out the window. We have been struggling to A) find the right rhythm so we can spend time together, but he gets enough sleep for work, and B) figure out what meals he wants and when.
Because his schedule is flipped from mine, he is getting home from work when I am getting up. My body is telling me it is time for oatmeal or eggs and his body is ready for a nice hearty meal.
Enter the make-ahead casserole.
It is not only easy for me, I just throw it together as I am making dinner so no extra time in the kitchen for me really. But it has that hearty comfort meal kind of feel that his body is craving. He can eat as much as he wants, and I can eat as little.
I can wake up, grab a cup of coffee, spend some time listening to how his day eerrrr night went, and even sneak in some couch cuddle time.
All while this glorious casserole is baking away in the oven.
DING breakfast errr dinner ummm brinner is done.
Mmmmmm, and I am still in my jammies working on my second cup of coffee.
PERFECT!!
Now if I could only figure out how to get the kitchen clean while I am relaxing on the sofa!

Yes yes YES! You know what, I actually still have bread leftover from the breakfast cake I made AND I have ham too!! I'm going to make a mini version of this just for myself!

Awesome! I love it when that happens. I had never thought of making a mini version. You will have to tell me how it comes out. Kevin is forever nagging me about "making enough for an army" but I tell him that after feeding my kids, plus most of the football team for years, that is just how I roll!!

Totally enjoyable one!! Thanks a lot!
