Sourdough & Sausage Strata

This wholesome, hearty, glorious sourdough & sausage strata casserole is everything I could ever want for Christmas breakfast.

It’s made with sourdough bread, eggs, yogurt, sausage, kale and roasted red peppers and can be made the day of or in advance for an easy meal prep idea.

The Delicious Strata Details

It’s packed with tangy sourdough bread, nutty Gruyere, salty breakfast sausage, sweet roasted red peppers, a luscious yogurty egg mixture and handfuls of sauteed garlicy greens (but shhhh, don’t tell). 

What I’m trying to say is… what’s not to love?

I seriously think everyone you plan to dine with on Christmas morning will fall in love with this strata, so you won’t have to cook several things to accommodate several people. 

And it can also be prepped in advance and just tossed into the oven when you’re ready. 

Those are serious wins in my book.

It’s Almost Like Monkey Bread

The other great thing is this sourdough & sausage strata is reminiscent of savory monkey bread.  I don’t know if such a thing exists, but it does now. 

I started eating a piece with a fork and quickly realized it was possible to just grab one spongy bread cube at a time, and when pulled off, a delightful string of cheese came with it, along with a piece of sausage and a bit of greens. 

It’s savory monkey bread, you guys.  MONKEY BREAD.  And the pieces on top are extra crispy and crunchy, so try not to fight over those pieces when you’re eating this strata straight out of the casserole dish with your family and friends on Christmas morning.

Who wants to wash more dishes?

And isn’t it just THAT much more satisfying to eat this strata/bread pudding/monkey bread concoction with your fingers?

I am sure of it.

And if you’re currently rolling your eyes at me, just try it.  You will never eat Christmas breakfast the same again.

  1. Had this to eat this morning, really delightful. Wish I could eat it every day. Also, it is great that you can bake it one day and eat it for a couple after that to save time throughout the week.
