It is possible to freeze cottage cheese without ruining it, but the freezing process changes the texture of this very soft cheese. However, it still works well in recipes that require baking, such as casseroles.
Those who plan to freeze cottage cheese should buy the whole-fat or large-curd variety. These varieties emerge from freezing in much better shape than the low-fat varieties. The best method is to put the container in the freezer right after purchase, setting it inside a freezer bag to ward off freezer burn. This extends the shelf life by as long as six months. Placing it inside the refrigerator is the best way to thaw cottage cheese.
