There are only two days left until Thanksgiving and oddly I am more prepared than ever. Why? Because Iโ€™m not cooking! Well, I mean, I will be cooking, but this year I wonโ€™t have our usual huge crowd. My family will be a bit split up (which is the weirdest thing). This is the first year inโ€ฆeverโ€ฆthat I wonโ€™t be with them. Itโ€™s also the first time in many years that I will not be roasting a turkey on Thanksgiving Day. Itโ€™s OK though, Iโ€™ve already roasted two whole turkeys this month alone. Plus, thereโ€™s a very good chance I will do so again on Christmas. So, donโ€™t you guys worry, I am not bummed.

All that said, while my family will be in Tahoe over Thanksgiving, almost everyone is currently here in Colorado now. My brothers have taken over my parentโ€™s house. Theyโ€™ve been making their way over to the HBH studio barnโ€ฆjust down the hill a little wayโ€ฆand requesting food and drink at least once a day. Itโ€™s the busiest time of year for us right now, but I just canโ€™t say no to them.

Since everyone is here, Iโ€™ve been looking to make more casseroles and bakes that feed our large crew and are easy to throw together. Iโ€™ve already made this one pot spicy pesto bake rigatoni twice in the last week. To switch things up a bit, I wanted to give the classic ham and cheese sandwich a fresh new update.

Which brings me to this cheesy bake thatโ€™s great for everything from breakfast to dinner. Itโ€™s rich, indulgent, and perfect for feeding friends and family.

With nine plus people in my family, I rely heavily on my Pyrex Deep baking dishes throughout the holidays. I love the added depth these dishes provide. I can conveniently layer food in them and easily feed the familyโ€ฆand friends. The new Pyrex Deep are the deepest glass baking dishes out there. They hold up to 50% more than any current glass bakeware. Obviously, theyโ€™re perfect for things like pasta bakes and lasagna. But I also love using them for pretty layered dips and desserts.

You can find Pyrex Deep baking dishes at Walmart and Pyrexhome.com.

Here is how to make this ham and cheese croissant bake.

The process is pretty simple. Toast some store-bought croissants in the oven to add a little crispness to them.

While thatโ€™s happening, make the mustard cream sauce, which is a simple mix of mustard, cream, eggs, and herbs. When the croissants are toasted, toss them in the sauce along with caramelized mushrooms, prosciutto (or deli ham), and cheese. Layer the croissant and cream in the Pyrex Deep, then bake.

Simple right? Yes, and SO GOOD.

But hold on, thereโ€™s moreโ€ฆ

The two ingredients you need mostโ€ฆ

Creamy Brie cheese and just a touch of everything bagel spice.

First, the brie. Itโ€™s not traditional in a ham and cheese sandwich, but I also have Brie in my fridge this time of year and love using it in my recipes to make them feel just a bit more special. Of course, you can really use any cheese you love. But weโ€™ve found the Brie to really take this simple bake from good to incredibly delicious.

Second, everything bagel spice. No, you donโ€™t NEED this, BUT it adds so much. You can mix up your spice blend or pick up some from Trader Joeโ€™s, Whole Foods, or order via Amazon.

This is a great dish to prepare ahead of time for holiday guests. We love enjoying this for breakfast, but itโ€™s also great as a dinner too. Either way, it will be loved by everyone.

I mean, itโ€™s pretty hard not to enjoy buttery croissants, cheese, and ham all baked together. It has the perfect marriage of French flavors. If you donโ€™t already have your Black Friday brunch recipe lined up, add this to the menu. Chances are youโ€™ll have all the ingredients in the kitchen anyway. This dish is also a great way to use up anything leftover from Thanksgiving Dayโ€ฆjust throw it in!

Remove from the heat and set aside.
    4. In a large bowl, whisk together the cream, milk, eggs, mustard, cayenne, and a pinch each of salt and pepper. Add the toasted croissants, mushrooms, ham, and Brie cheese, gently toss to combine. Pour the mixture back into the casserole dish. Top evenly with Swiss cheese and sprinkle with everything spice.

    made this dish yesterday and it was a BIG hit!. i used whatever i had in my fridge at the time which was hot salami, fetta, mozzarella and ever cherry tomatoes. I didn’t have the bagel spice and didn’t notice it missing at all as this dish is so flavoursome already. I have already been asked to make it again! THANKYOU!

    1. Tieghan Gerard says:

      Hey Samantha,
      Love to hear this! Thanks a lot for making this recipe and taking the time to comment. Have a wonderful Sunday!

    Hi! If I make ahead and freeze it, will it be soggy/ do I need to change how much time we need to bake it for?

      Hi Alex,
      That will be perfectly fine for you to do! I hope you love this recipe, let me know how it turns out for you!

    Hi, do you have any suggestions to make this a vegetarian dish by making a substitution for the prosciutto? Thank you!

      1. Hannah Laboon says:

        Hi! When freezing to make ahead, do you fully assemble and bake and then freeze? Or freeze not yet baked?

        1. Tieghan Gerard says:

          Hi Hannah,
          You can wait to bake and then just bake from frozen. I hope you love this recipe!

      1. Susy says:

  8. Kimmi Henard says:

    5 stars
    I made this a couple weeks ago, I cut everything in half because there’s only 2 of us. Next time I’m going all in, this was so good. I have a question…..
    *Could I use fresh spinach and is there a change in cooking if I do?

    1. Tieghan says:

      Hi Kimmi,
      Happy Friday!! Thanks a lot for giving this recipe a try, so glad to hear it turned out well for you! Sure, if you want to use fresh spinach I would just sautรฉ it down first and drain any liquid. XxT
