Croque Monsieur Casserole

A Croque Monsieur Casserole is a fantastic way to use up leftover baked ham. I love to make this for breakfast 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:

Not too satisfied with how it came out slightly dry but that's my fault, decided to add some ketchup to the top and it was the BOMB!

Takes a little bit of time to make his but I enjoyed it nonetheless for sure.

Didn't use whole milk instead went with soy and swapped out gruyere cheese with goat cheese cause I'm lactose.
