Croque Monsieur Casserole

This is from Melissa Clark’s new cookbook Dinner in French. I made a few minor changes including cutting the recipe in half. It is ridiculously rich and sinful.

4 tbsp butter

1/4 c flour

2.5 c milk

2.5 c grated Gruyere

1/2 tsp herbs de Provence

Salt

Pinch of nutmeg

8 slices white sandwich bread

6 oz thinly sliced ham

Heat oven to 375 and spray a 9×9 baking dish.

Melt butter in a medium skillet over medium heat. Stir in flour and cook, whisking, until it turns golden, about 3 minutes. Slowly whisk in milk and whisk until smooth. Stir in herbs, salt and 1 cup of cheese . Whisk till smooth.

Slather bread with mustard, top with ham, shredded cheese and another slice of bread.

Spread a small amount of sauce on the bottom of the baking dish. Place sandwiches in and top with sauce and any remaining cheese.

Bake for 30 – 40 minutes until brown and bubbling.

Serves 6.
