Nothing screams HOLIDAYS more than a breakfast casserole. We grew up on Christmas morning breakfast casserole. My Mom still makes the exact same breakfast to this very day. The nostalgia, ya know?
Well, I picked up the Half Baked Harvest new cookbook Super Simple. Flipped through it for a bit and stumbled on the most beautiful image. A breakfast casserole. With a more sophisticated name: Buttery Croissant Strata. I may have drooled.
Buttery croissants. Melty cheese. Crispy prosciutto. All baked to a warm goodness.
Thank you Half Baked Harvest for constantly making me want to try new things in my kitchen. You keep me inspired.

So, in true xoxo stacyb form, I swapped a few ingredients to make it more family friendly. You guys, this is going to be out Thanksgiving breakfast. Maybe I’ll take it to my Mom’s Christmas morning too! It’s like, THAT GOOD!

{breakfast croissant strata}
Here’s what you’ll need:
- 3 tablespoons butter, thinly sliced
- 6 croissants, sliced into thirds
- 8 eggs
- 3 cups milk
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh sage, chopped
- 1/4 teaspoon nutmeg
- salt + pepper
- 10 oz frozen spinach, thawed + drained
- 2 cups white cheddar cheese, shredded
- 3 oz sliced prosciutto, sliced into 2 inch pieces
Here’s what you’ll do:
Coat a 9×13 baking dish with non-stick spray.
Arrange croissants in the baking dish + top with sliced butter.
Bake until croissants are toasted about 8 minutes. Keep your eye on them.
Remove + let cool.
In a bowl whisk together, eggs + milk + Dijon + sage + nutmeg + salt + pepper. Stir in spinach + 1 cup of shredded cheese.
Pour mixture over toasted croissants. Top with remaining shredded cheese + prosciutto.
Cover + refrigerate for 1 hour (or overnight)
When ready to bake, preheat oven to 375 degrees.
Bake breakfast strata for about 45 minutes, until center is set. If croissants begin to brown, top the baking dish with foil + finish cooking.
Allow to cool for 5-10 minutes + serve.
Enjoy!
I served out strata along side another Christmas Morning classic: Cheesy Potatoes. This combo is OUT OF THIS WORLD. And I’m pretty sure it will also be requested for each holiday by your family!
