How to make Monte Cristo Casserole (step by step):

3. Cut open the 8 croissants then spread the mayonnaise evenly between all 8. Cut the deli ham and Swiss cheese into enough slices so that you have enough to divide evenly over the 8 croissants.
4. Cut each sandwich into 4 pieces then spread pieces out in the casserole dish covering all areas.
5. In a large measuring cup or bowl, whisk together the eggs, milk, and a dash of salt and pepper. Pour the egg mixture over the croissants, being sure to cover all areas.

Different ways to change up this recipe: 

• I kept the recipe more traditional for a monte cristo sandwich but feel free to add in some veggies if you wish. Chopped mushrooms, bell peppers, and/or onions would all work well. 
• You could get as creative as you wanted with this, by adding some chopped bacon or chopped sausage to the egg mixture. It’d make for a much meatier casserole. 
• For a bit of sweetness, you could spread sugar-free strawberry or blackberry preserves over the croissants before putting the ham and cheese on them. A sprinkle of powdered sugar over the top of the casserole would also make this more of a traditional monte cristo. 

Tips and Tricks for Making Monte Cristo Casserole: 

• You can bake the croissants earlier in the day or even the night before, or use leftover croissants even if they’re stale. They’ll soak up the egg and milk mixture like a bread pudding does. It’s best to bake them ahead of time because you want them completely cool before using them for the recipe. 
• Like most casseroles, this one freezes well. Bake up a few in aluminum pans and freeze them. You can gift them to new mothers or use it when you join a meal train for a family in need. 
• If you end up with leftovers (you won’t), store them in the fridge in an airtight container for up to 5 days. 
• Monte Cristo Casserole can be assembled ahead of time and baked when you’re ready for it. For example, make it up the night before, cover it with tin foil, and set it in the fridge. In the morning, when you’re ready for breakfast, all you have to do is bake it. Letting it sit allows the croissants to soak up the egg mixture.
