Prep this rich and creamy egg casserole the night before a special morning brunch. 
“Christmas Morning Eggs.” That’s what we call them.
I grew up with the most perfect Christmas morning routine, so when I became a mom, I really wanted my own children to enjoy my same traditions.
No one is allowed to go downstairs until mom and dad have made the coffee, blasted the Christmas music, lit the fireplace, tuned up the video camera, and checked to see if Santa has arrived.
When it’s time, we pose for pajama pictures on the stairs and when the last photo has been snapped, it’s game on! Kids go barreling into the family room with screams of joy and excitement at the site of Santa’s presents. Like my mom always did, I usually gasp at the sight of the tree almost coming down from one of the kids flipping and somersaulting into the room.
The entire morning is spent opening presents and snacking on cookies and Ammaw’s Heath Bar coffee cake. The adults sip bloody mary’s or mimosas, add dozens of batteries to new toys, and try to break gifts out of packages wrapped with 1000 twist ties.
The morning is actually full of so much energy and action that it’s a good thing breakfast comes easy. These eggs can be prepped the day before so on Christmas morning, all you have to do is fire up the oven and bake them until heated through. 
At about 2:00 when most families may be starting their dinners, we are sitting down in our pajamas, ready for brunch. 
The eggs are decadent and the bacon is salty and crisp…just a small scoop is all you need to fill your belly until Christmas dinner.
I wouldn’t and couldn’t have Christmas morning any other way.
Do you have a traditional Christmas morning recipe?

What size dish if doubling recipe (for 8) and any cook-time changes? How much sour cream if not doubling as well? Thanks!
What size casserole pan so you bake it in?

This looks so yummy! I love an easy make ahead meal!
We always do an egg casserole on Christmas morning, too! Looks delicious.
This sounds fantastic! We make a French toast casserole the night before and heat it up Christmas morning, so I’m all about the make-ahead, throw it in the oven dishes! This one might be a great option to change it up a bit for us!
That French toast sounds delicious! I think you can do both! Have a sweet and savory and fill your belly up! It’s Christmas! lol
Oh, I love the idea of a simple egg bake for Christmas morning! My dad was always in charge of Christmas morning breakfast (I’m assuminf, because mom was typically up late wrapping last minute gifts). He would make a potato-ish bake that reminds me of this. I’m excited to try this!
What a wonderful memory! That sounds so yummy too! Hope you love this dish!
Well now I just want to go and make this right now! Love a good egg dish!
Do it! lol. Enjoy! I love an egg dish too!
This is such a great casserole for the holidays. Some days you feel like you never have time to sit and cook breakfast
So true!
This is a great “hangover cure” recipe! Make it before you party, wake up and pop it in!
Yes! Genius! It definitely cures any headache and empty belly and just hits the spot!
Enjoyed reading about your childhood traditions. And I was just looking on pinterest for some overnight brunch ideas. This one sounds perfect.
Oh, thank you so much! I’ve tried many different egg casseroles but this is the one I always make.
Oh yum this looks so good! Breakfast casseroles are so good to make ahead for a relaxing morning!
Thanks! I love the ease of just popping it in the oven!
ohhhh! This looks amazing and I love the idea you can make it ahead which is always a bonus!
Thanks, Kiarna! It is so convenient having a ready to go breakfast.
