Recipe
Melt butter in heavy medium skillet over med-high heat. Add mushrooms and saute until golden, about 10 min. Season with salt and pepper.
Generously butter a 13x9x2-inch glass baking dish. Line bottom with half of bread slices, cutting to fit. Top with ham, then 2 cups of cheese. Top with mushrooms. Add enough remaining bread in single layer to cover. Whisk eggs, milk, 1 T. thyme, dry mustard, salt and pepper in large bowl to blend. Pour over bread. Cover and refrigerate overnight.
Remove from refrigerator and let sit 30 min. while preheating oven to 350 degrees. Uncover baking dish. Bake until puffed and golden, about one hour. Mix remaining cup of cheese and 1 T. thyme; sprinkle on top. Bake until cheese melts, about 3 min. Let sit for 10 min. before serving.
Serves 8-10
Note: Leftovers are equally as good re-warmed the next day in the microwave.
