Wild Mushroom Green Bean Casserole 
3 cups milk 
Bay leaf 
4 tablespoons unsalted butter 
1/4 cup flour 
1/4 teaspoon Dijon mustard 
Freshly grated nutmeg 
Salt and pepper 
1 cup grated white cheddar 
1 1/2 cups chopped green beans, cut in 2-inch pieces, blanched 
3 cups sliced assorted wild mushrooms (such as portobello, shiitake, or cremini) 
1/2 cup freshly grated Parmesan 
1/2 cup buttered bread crumbs 
Make sauce: In a saucepan scald milk and bay leaf. In another saucepan, melt butter over medium heat. Add flour and cook, whisking constantly, 2 minutes. Remove bay leaf from milk and slowly pour into butter-flour mixture, whisking constantly. Season, to taste, with mustard, nutmeg, salt and pepper. Cook, stirring occasionally, until thickened, about 5 minutes. Remove from heat and add cheddar, stirring until melted and smooth. 
Heat oven to 350 degrees F. Fold green beans and mushrooms into sauce, then transfer to a buttered casserole. Sprinkle top with Parmesan and buttered bread crumbs. Bake 50 minutes, or until casserole is bubbly and topping is lightly browned
