Cut bread into 1-inch cubes, removing crusts if desired. Lightly grease an 8x10x2-inch glass pan.
Place bread cubes in the bottom of the pan. Top with sausage and cheese.
Mix the milk, half-and-half, Worcestershire sauce, dry mustard, onion powder, and eggs together. Pour over the top of the bread mixture. Cover and chill overnight.
Bake, uncovered, for 35-40 minutes, or until done. To check for doneness, insert a knife in the center of the casserole. It should come out clean. Serve hot.
