Mexican Casserole

An unopened store-bought Mexican Casserole, if refrigerated, can last for up to 1 to 2 days past the printed date on the package. Once opened, consume it within 3-5 days for best quality. If you've prepared your Mexican Casserole at home, aim to eat it within 3-4 days if refrigerated. Frozen Mexican casserole can last up to 2-3 months. Always remember to consider the expiration of individual ingredients while determining the time frame.

Signs indicating that a Mexican Casserole has gone bad include the presence of mold or a stale, sour smell. The appearance of the casserole may change as well - if the top layer hardens or if the casserole becomes excessively watery, it might be time to dispose of it. Any change in taste also suggests that the casserole is no longer good to eat. If you're unsure, it's safer to discard it.

• Keep the casserole refrigerated at all times when not being served. • Store it in air-tight containers to maintain its freshness for a longer duration. • Mexican Casserole freezes very well — to freeze, simply let the dish come to room temperature and then store it in a freezer safe container or heavy-duty freezer bags. • To defrost, remove the casserole from the freezer and place it in the refrigerator for 24 hours. • It's not recommended to refreeze the casserole after it’s been defrosted, doing so can affect the quality and taste of the dish. Remember to only defrost the exact amount you need.
