Why is holiday brunch so fantastic?!
This overnight french onion croissant bake is the epitome of holiday breakfast. It’s prepared ahead of time, completely indulgent, tastes wonderful, special, fancy and also feeds a crowd.
It checks all the boxes for a great holiday meal!
A few years ago I fell in love with this overnight croissant breakfast bake. We love it SO MUCH. I only make it once a year – sometimes twice. It is a very filling and decadent breakfast, and I have never made something that absolutely everyone loves so much.
We all look forward to this on holiday mornings. It’s unbelievably good.
This year, I decided to “french onion” the breakfast casserole! Oh yes, I remove some of the spinach and instead, add a ton of caramelized onions. It tastes just as good as it sounds!
Here’s how I make it!
I start with the caramelized onions. This recipe is a little high maintenance because you have to caramelize the onions, then let this sit overnight. But I promise it is 100% worth it.
I caramelize three or four large sweet onions. This will take around 60 to 90 minutes, maybe even longer. I like to start mine off a little higher, then turn them down after 20 minutes or so. I find that this really speeds up the process.
One reason I love this so much is because it’s made with croissants. I have always been a huge croissant lover! The base of this starts with croissants that are toasted until the broiler until they get wonderful, crisp and caramely bits.
The custard is made with eggs, cream and freshly grated gruyere cheese. It melts like HEAVEN.
Everything is tossed together: the toasted croissants, eggs, cheese and caramelized onions. Then it chills in the fridge overnight! This is key. You can’t skip this part!
In the morning, remove it from the fridge and bake it up. It’s cheesy, melty, crisp, crunchy, savory, sweet and everything you want.
This gets so golden in the oven. The croissant pieces soak up all the egg and the mixture has the most perfect souffle-like texture.
I mean, just look at this!
This is a fabulous holiday brunch idea – or even one to make on christmas night after a day of lounging around. It’s incredibly satisfying.
And it’s feeds tons of people! (more…)
