Overnight Ham & Cheese French Toast Casserole

I am a big fan of overnight casseroles on hectic holiday mornings. Heck, I’ll take one any day of the week! This Monte Cristo Breakfast Casserole is a favorite at our house. French bread, honey mustard, Canadian bacon, Swiss cheese baked in a french toast batter. YUM! Make this the night before and pull it out when you wake up and bake. SO easy and it tastes GREAT!!

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. Sandwich Canadian bacon and Swiss cheese between each slice. Whisk together eggs, half-and-half, milk, sugar, and vanilla. Pour the mixture over the bread, cover, and refrigerate overnight. Remove the dish from the refrigerator and bake.

  • Can use any bread you prefer – French, Italian, or Brioche all work well.
  • If you can’t find Canadian bacon, you can substitute sliced deli ham.
  • I used thinly sliced Sargento’s Swiss cheese. If you can’t find that, I suggest cutting each cheese slice in half unless you like a lot of cheese.
  • Can Monte Cristo Breakfast Casserole be frozen? Yes! You can freeze the casserole baked or unbaked.
    • To freeze the baked casserole, cool the dish completely. Cover with plastic wrap and aluminum foil and freeze. To reheat, thaw completely, and bake covered in the oven at 350ºF until warm.
    • To freeze the unbaked casserole, pour the egg custard over the bread. Cover the dish with plastic wrap and press down on the bread. Add another layer of plastic wrap and then cover the dish with foil and freeze. Write the baking directions on the foil. To bake after freezing, thaw completely and bake as directed.

Make-Ahead Holiday Breakfast Casserole

This casserole 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. We usually sprinkle the casserole with some powdered sugar and top our slices with raspberry jam. It is also great with syrup or plain! Give this a try the next time you need an easy and delicious breakfast for a crowd. I promise it won’t disappoint!

  1. 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

  2. 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.

  3. 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!
