I adore having our friends over and cooking for them. Bill and I are part of a small dinner club and it was our turn to host.

We gathered for brunch and I warned them that the recipes I was serving were not tried and true. Thankfully, every single dish was a hit.

Bill loved the mushroom and chicken crepes, Mike and Mary Ann were fans of the Strawberry Cheesecake Trifle, John fell hard for my coconut cream pie, Bill’s grilled bacon and the chicken apple sausage. Tops in my book was this Gruyere Spinach Strata!

A Simple Make-Ahead Casserole Recipe

If you’re ever serving brunch to a crowd, whether it be overnight guests or family gathering for the holidays, an easy, make-ahead dish is imperative. And one that is absolutely scrumptious is just as important.

Defrost your spinach, grate the cheese, and cube the bread ahead of time. The night before, you can mix up the custard place all the other ingredients in a casserole dish and pour the eggy mixture onto the bread. Park it in the fridge and bring it out for an hour or so before baking to take the chill off.

You will be delighted with the results! Warm and cheesy comfort food. You can’t beat that.

  2. I had my first strata at a baby shower not too long ago and loved it. Not sure why I haven’t experience one yet. Now I am all about about tackling one on my own. Yours looks and sounds marvelous. I think it would be a safe bet to be my first!

  3. What a delicious bread pudding! Happy Holidays, Liz!

  8. Would have loved to be at this brunch party, all the dishes sound amazing. And I have made such savory bread puddings a few times, they are awesome. Love the flavors in your here so must try.

  9. This sounds awesome – all of the flavors are right up my alley, from the spinach to the dijon mustard, to the gruyere. You make it sound so simple – thanks Liz I’m definitely going to try this!

  10. Merry Christmas and hope you and your family have a happy and healthy new year! This strata is gorgeous and will definitely be bookmarked for Brunch in the new year.

  11. This does look perfect for a brunch and I like how it can be parked in the fridge overnight then all you need to do in the morning is heat and serve. Great dish for a cold winter’s morn xx

  12. Need this. Although it all sounds delicious (I love brunches), this would have been my favorite also. What I like best about this, secondary to the taste, is the do-it-early component. My kind of dish. Happy New Year, Liz to you and your family.

  13. — I wish I would have made this on Christmas Eve! WOWWWW. x

  14. It always amazes me how creamy these strata can be. GREG

  15. Such a hearty dish and I can see why it was a hit! Happy New Year!

    I LOVE spinach, and with cheese – it’s a great combination.
    I must say it also looks wonderful

    Happy New-Year Liz ! ❤

  17. Liz, you food shots are enough to drive me hungry! Happy 2016, babe! xoxo

  18. Hi Liz, I can see myself enjoying this most mornings, very dangerous indeed. Looks amazing. Happy New Year’s!

  19. This is such an amazing casserole! LOVED it! Wish we could send you some of the graviera we have in the fridge right now dear Liz. It’s from Naxos, and it’s much more flavorful than Swiss Gruyere. If you can find any type of Greek graviera give it a try, especially with some sort of pasta, you won’t have to add parmesan at all!:)
    Thank you for another delicious post!
    Lots of hugs!

  20. I have made this and it is delicious. You can add more vegetables to this. I sauted bell pepper, mushrooms and added chrrry tomatoes to the recipe. You can add asparagus or any other veggies to suit your taste. 

  21. We had overnight guests and I made this. It was completely devoured!

  22. This was a huge hit at my house!! Can’t wait to make it again!
