Croque Monsieur Casserole

Recipe Description

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:

Superb family favorite. Made this for brunch after Christmas and everyone loved it. I used leftover ham from our holiday dinner. The kids couldn’t get enough of it. So easy to prepare the night before too.
