To dry the bread overnight, spread the bread cubes in shallow baking pans and let stand overnight at room temperature. Store in an airtight container at room temperature for up to 1 week. Prepare the stuffing as directed and place in the 3-quart casserole (do not bake). Cover and chill for up to 4 hours. Preheat oven to 325 degrees F. Cover and bake for 45 to 55 minutes or until stuffing is heated through.
