About This Recipe
A traditional Monte Cristo Sandwich is like a combination of a delicious ham and grilled cheese sandwich, and French Toast. This classic French dish dips the sandwich in an egg custard and is grilled. It is then served with sugar and jelly if desired. It’s the perfect combination of savory meat, melty cheese, and sweet toppings. This casserole takes all of that and makes it easy to bake for a crowd.
Can this be made ahead of time?
It’s also an easy recipe to make ahead of time. You can make a double batch of this casserole and keep one in the freezer, for the next time you need breakfast in a hurry. It will stay good in the freezer for up to 3 months.
- Prepare the casserole as directed in a 9×13 baking dish or divide evenly between 2 smaller (8×8) aluminum foil baking pans.
- Wrap pan tightly with plastic wrap, then aluminum foil, before freezing up to 3 months.
- Remove plastic wrap and foil before baking.
- Bake, covered with foil from frozen for 30 minutes.
- Uncover and bake an additional 30 minutes.
How to Store
- Serve: After baking your casserole, don’t leave it at room temperature for more than 2 hours.
- Store: Once you’ve let it cool down, you can store casserole in the fridge for up to a week. Cover the baking dish tightly, or put it in another airtight container.
- Freeze: To freeze your casserole put it in an airtight container. It will keep well for up to 3 months.
Variations
- Meat: A classic Monte Cristo Sandwich is made with turkey and ham. However, if you want to change things up you could try using bacon, turkey bacon, or even putting some sausage in your sandwich.
- Cheese: You can also experiment with the cheese in your casserole. Instead of Swiss, try using Cheddar, Muenster, Gruyere, or Jack cheese.
- Bread: French bread tastes amazing in this casserole, but you can feel free to experiment with different kinds of bread. Try using sourdough bread, brioche, wheat bread, or challah.
- Toppings: This sandwich has a wonderfully unique combination of sweet and savory. In this recipe we have a brown sugar topping, however you can add even more to that sweetness. This sandwich is classically served with powdered sugar and jelly. Sprinkle powdered sugar over the top while it’s still warm and put out jelly for everyone to add as much as they want.

Hi, I’m considering using this recipe for an afternoon baby shower. If I assemble it in the casserole pan the night before, will it hold up alright if I refrigerate it overnight then cook it mid-day before the shower? Or should I assemble and cook it all the morning of?
You can assemble the night before. Cook fresh though and dust with powdered sugar right before serving.
Simple to put together and tasted delicious! It was a hit! I paired it with your recipe for hash brown casserole! Will be making this again!
