Make Thanksgiving stuffing ahead of time by preparing the croutons the night before and storing them in an airtight container, then preparing the remaining ingredients and assembling the dish the following day. You can also make it ahead of time by assembling the recipe from start to finish, then covering the baking dish and letting it sit in the refrigerator overnight. Before reheating, pour ½ cup vegetable stock over the mixture and gently fold it in before adding the dish to the oven and baking as instructed.
