A Croque Monsieur Casserole is a fantastic way to use up leftover baked ham. I love to make this for brunch in the days after Christmas when I am always looking for ways to use up leftovers. A croque monsieur is a traditional French sandwich which is made with boiled ham and sliced cheese between slices of bread and topped with grated cheese, salt and pepper.
I usually make this take on a croque monsieur by slicing a 1 day old baguette into 20 slices. If your baguette is fresh, toast it lightly beforehand. Layer up the bread, cheese and ham in a casserole dish before pouring over a whisked egg and milk mixture. Bake the casserole in a preheated oven until it is golden brown on top. I often prepare this dish the night before and simply place it in the oven the next morning.
To make Croque Monsieur Casserole, you will need the following ingredients:
Cut half of the baguette slices into ½ inch chunks. Toss the bread chunks in a bowl with the melted butter.
On the remaining slices of bread, spread the dijon mustard.
Overlap the slices of bread in the casserole dish and sprinkle ½ cup of the cheese over the top.
Fold the ham slices in half and place them in an even layer over the bread and cheese. Sprinkle half of the remaining cheese on the ham.
Scatter the buttered bread chunks on top and sprinkle over the remaining cheese.
Whisk the eggs and milk together in a large bowl and season with salt and pepper. Pour the egg mixture over the casserole. Allow to rest at room temperature for about 30 minutes.
As the casserole rests, preheat the oven to 400˚F.
Bake the casserole in the upper third of oven for 30 minutes until it puffs up and the top is golden-brown and slightly crispy.
Allow to cool for 5 minutes before serving.
This Croque Monsieur Casserole is a delicious and novel way of using up leftover ham! Try it next time you have leftover ham and don't forget to come back and leave a review with your thoughts.
