How can I grate soft cheeses?

I usually freeze mozzarella and then grate it (longer the better, unless you are in a hurry, then 20 minutes or so works OK). This works very well. Other soft cheeses, such as those meant to be eaten at room temp, brie, for example, I wouldn't freeze... Of course, I don't think many of us are grating brie anyway.

I find that mozzarella (and other soft cheese) is good sliced. I wouldn't want to freeze the cheese unnecessarily, just so I can get to use a grater.

I think it's really only worth grating hard cheese.

Freezing cheese will force out moisture within the cheese, ruining some of its desirable characteristics. This may not matter for cheap cheese, but that $4 ball of today's fresh mozz might give you pause. You could still use the freezer though. Putting a soft cheese in the freezer for several minutes prior to serving will firm it up enough to grate it more cleanly.

Another option is to grate it into larger chunks. Use the coarsest grater for the softest cheeses.

Use a box grater instead of a mandolin. Because the mandolin has a larger blade, it's placing stress on a much larger piece of the cheese resulting in large breaks. If you use a box grater, you get more localized pressure on the cheese for shorter periods of time. You'll still get some breaking with mozzarella or cheddar, but not nearly as much. Any breaks in the cheese will also be much closer in size to the final shredded product than with a mandolin grater.

Spray the grater with cooking spray or rub the outisde with a little oil on a paper towel. It'll go through the grater much more easily.

I freeze the cheese then put in in small chunks into the magic bullet with the flat blade and in no time I have grated two pounds of cheese.

A potato masher works ok in a pinch.

I freeze any soft cheese and grate straight onto the pasta. The heat will automatically defrost it for you.

I would tend to tear mozzarella for pizza or as a topping to focaccia.

For other soft cheese, slicing it with a chef's knife works fine; putting the diced cheese into a bowl of water can help it stop sticking back together. For example, when making a salad with ripe brie, I slice the cheese during prep, then drain and add it just before tossing the salad.

(if this is for pizza which it may not be) With Muenster maybe just use a cheese slicer and put thin slices all over the pizza instead of grated Muenster.. Muenster melts nicely ???

There are special graters for this. They have a drum blade within a housing, you put the cheese piece in the housing and turn a handle while pressing the cheese towards the drum. As long as the cheese is not so soft that it's smearable (like cream cheese) you can grate it with this thing perfectly.
