Stepping up our holiday breakfasts with this Ham and Cheese Croissant Bake. Buttery croissants, Brie cheese, prosciutto, and mushrooms, all tossed together in a mustard “cream” sauce, then baked to golden, cheesy perfection. This a cross between your favorite ham and cheese croissant sandwich and your mom’s old school Christmas morning strata. It feels extra fancy but is actually SO EASY, and of course, SO DELICIOUS. Bonus, it’s just as good for breakfast as it is dinner. And the best part? You can prep this croissant bake in advance, then bake it off just before you’re ready to serve. Perfect for holiday entertaining!
There are only two days left until Thanksgiving and oddly I am more prepared than ever. Why? Because I’m not cooking! Well, I mean, I will be cooking, but this year I won’t have our usual huge crowd. My family will be a bit split up (which is the weirdest thing). This is the first year in…ever…that I won’t be with them. It’s also the first time in many years that I will not be roasting a turkey on Thanksgiving Day. It’s OK though, I’ve already roasted two whole turkeys this month alone. Plus, there’s a very good chance I will do so again on Christmas. So, don’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 parent’s house. They’ve been making their way over to the HBH studio barn…just down the hill a little way…and requesting food and drink at least once a day. It’s the busiest time of year for us right now, but I just can’t say no to them.
Since everyone is here, I’ve been looking to make more casseroles and bakes that feed our large crew and are easy to throw together. I’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 that’s great for everything from breakfast to dinner. It’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 family…and 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, they’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 that’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, there’s more…
The two ingredients you need most…
Creamy Brie cheese and just a touch of everything bagel spice.
First, the brie. It’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 we’ve found the Brie to really take this simple bake from good to incredibly delicious.
Second, everything bagel spice. No, you don’t NEED this, BUT it adds so much. You can mix up your spice blend or pick up some from Trader Joe’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 it’s also great as a dinner too. Either way, it will be loved by everyone.
I mean, it’s pretty hard not to enjoy buttery croissants, cheese, and ham all baked together. It has the perfect marriage of French flavors. If you don’t already have your Black Friday brunch recipe lined up, add this to the menu. Chances are you’ll have all the ingredients in the kitchen anyway. This dish is also a great way to use up anything leftover from Thanksgiving Day…just throw it in!

Hi Paul,
Happy Friday!! I love to hear that this recipe was a winner, thanks so much for giving it a try!! xTieghan
Hi! This recipe looks delicious. Unfortunately there’s two of us who don’t like mushrooms. Could those be left out all together and still be yummy or is there an alternative you suggest?
Thanks!
Hey Meg,
You can totally just omit the mushrooms or sub any other veggies that you enjoy:) Please let me know if you give the recipe a try, I hope you love it! xx

Love this. Can this be made and baked ahead and frozen? And if so, how do I reheat?
Hey Marie,
Thank you so much for trying this recipe, I am thrilled that it was enjoyed!! I probably wouldn’t freeze this, reheating egg can be tricky. xTieghan

Hey Aisha,
Awesome!! I love to hear that this recipe was a winner, thanks a bunch for giving it a go! Have the best weekend! xxT
We had a breakfast themed family Valentine’s dinner. This casserole was a hit! I did end up having to bake it a bit longer because it was only completely done around the edges at the 45 minute mark. I added spinach & onion as well and cut some heart shapes out of the ham to put on top. It was perfect. Thanks for a great recipe!
Hey Kali,
Awesome!! Thanks for giving the recipe a try, I love to hear that it was a hit!! xxT
If there were leftovers, would you throw this in the fridge and then back in then to reheat?
Hey Julia,
You bet! I would just cover with foil and reheat on low. Please let me know if you have any other questions! xTieghan
I hate adding changes to peoples posts but I’ve done something very similar but it’s with poached and smoked salmon only real difference was it had cubed Camembert in it and sour cream purple onion and lots of dill .you can make it up the night before .The recipe was from the cheese company in Quebec
Sounds like a great idea!!
Amazing! It was a winner amongst our New Year Eve breakfast spread this morning – highly recommend. We ended up adding yellow & orange bell peppers as well – delish!
Hi Angelica,
Wonderful! I am thrilled to hear this recipe was enjoyed, thanks for giving it a go! Happy New Year!? xTieghan
I make a breakfast casserole every Christmas morning. I made 2 of yours to try, this being one of them. Everyone agreed it was the best Christmas breakfast I’ve ever had. This casserole was spectacular! The combination of the buttery , crispy and gooey crescents with the savory flavors from the ham and Brie was divine! A real winner!
Hey Christine,
Wonderful! I am thrilled to hear this recipe was enjoyed, thanks for giving it a go! Happy New Year!? xTieghan
Is the bottom supposed to be more on the moist side? I baked it quite a bit longer than what was recommended in the recipe. I even mixed it around a little bit as well (despite not wanted to ruin the beautiful crispy top) and the bottom was still a little too moist. The flavors were really good though! We ended up just eating the top and put the bottom half back in the oven so we can enjoy it for breakfast tomorrow.
Hi Lacie,
Thanks for giving the recipe a try. It should be soft, but not wet. Was there anything you adjusted in the recipe? Please let me know how I can help for next time! xTieghan
