How long can tofu be kept in the fridge after its opened? Are there any ways to extend the shelf life of tofu, either before or after opening the package? Can tofu be frozen so that it keeps longer? Does firm or soft tofu last longer in the fridge?
In my experience, tofu can be kept in the fridge (in it's original packaging) for at least a week, and probably up to two. Once it's been removed from the packaging any that's left over will need to be kept in a container and submerged in water. This should last about a week but probably not much longer. I freeze my tofu regularly. Sometimes I'll buy more than I need and keep one package in the fridge and the rest of it in the freezer. It should last as long as you need it to in the freezer, so long as you aren't intending to keep it for a year or more. Once it starts getting a bit slimy, it's time to throw it out.
