Many of the following dishes can be made ahead of time, frozen, and reheated, ideal when preparing in advance for a big party. To keep a casserole from getting soggy if you're traveling, allow it to cool before wrapping in plastic wrap. When you reach your destination, give it a quick reheat in the oven. If you are taking a dish and plan to cook the casserole once you reach your destination, wrap the frozen casserole in heavy-duty plastic wrap. Wrap covered casserole in towels, and place in a cooler. The casserole will stay frozen for 1 to 2 days.
