So now that we’re finished with crafting & planning our St. Patrick’s Day menus, we’re already moving on and thinking ahead to the next big hoo-rah, Easter. 

Which is probably a good thing since it’s right around the dag on corner. In two weeks to be exact, and we’re out of town on a long weekend this coming weekend- so I need to be prepared.

While the main course for us is a very large dinner, built around a spiralized ham- brunch is still super important if we’re hosting guests. 

No matter how early dinner is, nobody can ever seem to tide themselves over completely without some solid fare in the AM hours. So brunch it is!

At the same time, I’m already cooking and elbows deep in prep for the main event. So how am I going to make two major meals happen successfully and flawlessly?!

Again, this is why I love brunch so much. I can easily prep platters of eggs, sausages, even hash browns, etc with minimal effort. Throw in a fruit salad and once central casserole and I’m in business.

This Monte Cristo Style Breakfast Casserole is the secret recipe in my hostess’ apron.

I imagine some of you might be wondering exactly what a Monte Cristo is exactly. Don’t worry, until about a year ago I had no idea either. Believe it or not, I’d never even heard of them which I now consider a personal travesty.

A Monte Cristo is a essentially a fried ham & cheese (typically Swiss) sandwich, and is a twist on the more traditional French croque-monsieur. This mostly savory sandwich is often lightly sprinkled with powdered sugar before serving, and plated with a side of raspberry fruit preserves.

In short, it’s the best breakfast grilled cheese you’re ever gonna eat, with or without the optional sugar and preserves. Although, I highly recommend them to really get the full experience.

  1. This is something completely new to me but I can see how it would make a great brunch dish. I’d never have thought of serving it with powdered sugar or preserves so I’m excited to see what my family think of that. Thanks for sharing at Fiesta Friday.

    1. Don’t knock it til ya try it, Karan! LOL, but really like I said in the recipe, it’s totally optional. It’s just as yummy without it 🙂

  2. I am going to try his. Sounds so good. Years ago, there was a gourmet restaurant in my town which served a dessert omelette – it was filled with preserves and sprinkled w/confectioners sugar….delish! So, I can totally picture it working in this recipe.

  3. Can you prepare and bake this recipe the night before, refrigerate and heat for breakfast in the morning? School mornings leave little time for baking but I can reheat something already baked. If so, what temperature to reheat and for how long?

    1. Definitely! I’d put it in the oven at 325 for 15-20 minutes, or until hot throughout. I totally can relate to busy school mornings. Meal prepping breakfasts is my saving grace!

    1. It easily could be! I’d do low for 6-8 hours, and start watching it/checking for done-ness at the 6 hour mark.

  4. I would think that you could do this in a crockpot. Since the author is so good at replying to questions in a timely manner, I thought Before replying I would see if the originator would comment. When I asked about “making ahead” I got a quick reply. It came out perfectly by the way. Hope you have the same luck as I did. Please let me know if it is adaptable to the crockpot.

    1. Sorry, Mary. I do really try to reply promptly, but sometimes my own life gets in the way and it takes some time. I did reply earlier to the original poster of the crockpot question (I’ll have to double check that it went through), and let her know that it should work just as well in the crockpot. I suggested cooking for 6-8 hours, on low- and begin checking at the 6 hour mark for ‘doneness’.

    This was really good! I didn’t have a whole loaf of French bread so I added a couple chopped up bagels. I think the bagels helped it not have a soggy texture or bread pudding texture. It was perfect and reheats really well. Don’t skip the powdered sugar and preserves. It totally makes the dish!!

    1. I love the idea of using bagels! And you’re so right, the powdered sugar & preserves are an essential part of the equation.

    Try some oysters & spinach in this, pinch of old bay, put oysters in later to not over cook, no sugar or preserves, top with french fried onions & parmesan cheese. Nice dinner meal

  7. Not a fan of ham, can anything else be used in its place? I know it kind of defeats the whole purpose of this recipe, since you mentioned the name of the recipe stands for ham & cheese, but no one in my family eats ham!

    1. You can definitely make it ahead of time, but I would also bake it before freezing. Then when you’re ready to use it, pop it in the oven until it’s heated through.

    I have made this several times and it is soooo good. I serve it with powdered sugar and a sauce I make with berries. I’ve also used whatever bread I have around. Even cut up bagels. Turns out great every time.

    1. So glad you enjoyed it, Rachel. I love the idea of using bagels in it. I’m going to have to give that a try next time I make it. I like to serve mine with raspberry jam- but any berry sauce would be delicious!

  9. 5 stars
    That was AMAZING!!!! I will make it the next holiday when all the kids are home. So easy and delicious! The powdered sugar and warm jam is a must. Thank You!!!

    1. You’re so right, Jacolyn- those little extra garnishes really are what sets a serving of this casserole apart! It’s good by itself, but those elevate it to greatness.

    I cannot believe how delicious this was. Also how easy to prepare.We are camping in an RV and had company this morning. They raved about how good it was. I prepared it the night before and baked it the next morning.I used heavy whipping cream. I only had a 9 inch square pan. Baked it 45 minutes. Served it with a fresh fruit compote. This served 4 of us with some left over. This will become a special morning breakfast at our house, Can’t wait to fix it again. Thanks so much for the recipe.

    I love the Monte Cristo at Blue Bayou in Disneyland. This is such a yummy way to enjoy the same flavors. I used what I had so my bread was some torn up bagels and English muffins. Turned out perfect!! I know the sugar and preserves sound weird but it’s a must! It rounds out all the flavors! Don’t skimp on that. Try something new. You never know…

    This was an epic fail. I doubled the recipe and used a larger pan. Very expensive failure. I am a very experienced cook and baker and have never had a failure like this. It was awful. Dumped it in the garage. No taste. Don’t waste your time or money on this garbage

    1. I’m so sorry you had this experience. What exactly went wrong? Did it not bake through? You just found the taste too bland? Happy to try and help trouble shoot as we’ve never had any of these issues before.
