Does green bean casserole have to be refrigerated? How do you reheat frozen cooked green beans?

Yes, green bean casserole should be refrigerated. Green bean casserole should be kept in the fridge for about four days.

However, once left at room temperature for more than two hours, it will begin to lose its flavor. If you have any leftover casserole, you should put it back into the fridge immediately after preparation.

As for reheating frozen cooked green beans, it is suggested that you reheat green beans by placing them in a microwave-safe bowl, sprinkling them with some water, and microwaving them for a few minutes.

Heat the dish for 30 seconds at a time, covered with plastic wrap, until it is hot. Heat a pan over low heat for about 5 minutes to reheat on the stove.

Green bean casserole is easy to make and can be prepared ahead of time, which makes it a convenient option for holiday meals.

Green bean casserole can be served as a side dish alongside roasted turkey, ham, or beef.  Green bean casserole pairs well with other classic Thanksgiving dishes such as mashed potatoes, stuffing, and cranberry sauce.
