How to Make Monte Cristo Breakfast Casserole

This casserole is very easy to make. Start with slicing a loaf of French bread into slices. Spread the front and back of each slice with some honey mustard. Place the bread in a baking dish.

What to Serve with Monte Cristo Casserole

This casserole is a family favorite! We love this for breakfast, brunch, lunch, and dinner. It is one of our favorites to make on Christmas morning. I love not having to mess with breakfast before we open presents and make a batch of Jolly Juice Mimosas

When it comes to what to serve alongside this dish, the possibilities are endless!  A side of fresh fruit, such as a colorful fruit salad or a medley of sliced berries, is a perfect choice to balance the casserole’s richness with a burst of natural sweetness and a refreshing touch. For a touch of indulgence, consider serving it with a dollop of whipped cream or a drizzle of maple syrup. If you’re looking for a more substantial pairing, cheesy grits or roasted potatoes make for a hearty addition, adding a delightful contrast in texture. No matter what you serve with this dish, it is sure to be a hit!

  1. Just prepped two pans of this for Mother’s day brunch tomorrow. Used Brioche and it smells heavenly already. Can’t wait to dig in tomorrow. Thanks for a great recipe!

  2. Used your recipe for Christmas breakfast and all enjoyed it.
    But today, I needed dinner in three hours so I used what I had. Two english muffins halved gave me 8 slices, I had 5 slices of swiss cheese also halved and a sandwich baggie of sliced ham. Spread the mustard and arranged the rest in a small casserole dish. Whipped 3 eggs with 1/2 T sugar, 1/4 T maple syrup and 1 cup of cream. Let it set for 2 hours and then baked for 45 mins. Turned out great, my husband is eating it up. He has diabities so did not use my daughter’s current jelly, but I did. Loved it

  3. We are confused. The instructions sound like you lay the bread down in the pan, however, the pictures look like the slices are standing up. We are avid followers and have enjoyed many of your recipes and Meow Mondays! This one has us baffled.
    Thank you!

    1. I don’t say to lay the bread down. I say to arrange the bread in the pan. You can see how the bread is arranged in my pan in the photos.

  4. I’m so trying this, but May I share a shortcut? I love the flavored creamers, and for French toast, I substitute the heavy cream for flavored creamer of my choice, and omit any other flavoring. I plan on doing that with this recipe. I’ll still use the milk as directed. I can’t wait to try this. It may be supper tonight!
