A savory strata is the perfect make ahead meal! Combine bread cubes with some add-ins and cheeses. Toss with a quick egg mixture and refrigerate overnight. 

While the mixture sits overnight, it soaks up the egg mixture and is ready to be baked in the morning. A great meal for a lazy morning or when you have guests!

What is a Strata?

A strata is a super-easy-to-make breakfast almost like a savory bread pudding (and truly, it’s great any time of day!).

Bread is cubed and tossed with flavorful ingredients (in this case brie and mushrooms). It’s tossed with egg/milk mixture and sits overnight. As it sits, the bread soaks in the mixture and in the morning it is baked until puffy and set.

Best of all, you can use this base to use up any ingredients you have on hand from leftover taco meat to roasted asparagus.

Frittata vs. Strata

A frittata and a strata are both essentially breakfast casseroles. A strata has a more soufflé-like appearance while a frittata is more similar to a baked omelet.

A strata often includes bread cubes while fritattas can have potatoes or even pasta along with the add-ins.

PRO TIP: Letting the strata set overnight ensures the egg mixture is completely soaked into the bread cubes so it puffs up almost like a soufflé.

  1. This recipe was delicious. I made it exactly as written with the exception that I could not find Cremini mushrooms and just used the regular white mushrooms and a little extra cheese. Everyone had a second helping. I froze what was left over and it reheated very well. I cant wait to make it again and will experiment the next time and maybe try some different vegetables.5 stars

  2. This looks really good! Can’t wait to make it and portion it out for a quick daily breakfast during the week.

  3. Hello. This looks yummy. Having a girl’s brunch soon. Instead of bread cubes, could this be made with a phyllo crust, then pour all other ingredients on top? Thank you.5 stars

    1. I haven’t tried this so I can’t say for sure if it would work, but it sure does sound delicious! If you try it I would love to hear how it turns out Cyndy!

  4. What can I use instead of mushrooms? My husband won’t eat them? Would cubed cooked ham work? Or cooked and crumbled breakfast sausage?
    Thanks Holly! Ally-O in NJ

  5. This sounds wonderful. Thanks for making it a smaller size. 9×13 is just too large for this household but a 9×9 would work great!
