Preparation
Step 1
Preheat the oven to 400 degrees F. Grease an 8-inch square baking dish.
Melt 6 tablespoons of butter in a large skillet over low heat until bubbling. Whisk in the flour and cook for 1 minute. Slowly whisk in the milk and cook until thick and bubbling, 3 to 5 minutes more. Whisk in the mustard, salt, pepper, and nutmeg.
Pour a thin layer of the sauce into the prepared baking dish and cover it with 5 or 6 slices of the bread, then slices of the ham and an even layer of the Gruyere. Repeat the layers once more, ending with a third layer of sauce to cover all. Bake the casserole for 30 minutes. Remove it from the oven and cut into 6 equal pieces.
