If you make this soup with the intention of freezing it, don't add the half and half or tortellini to any of the frozen soup portions. These can be added after the soup has been defrosted and reheated and will help keep the dish from separating as dairy does when frozen and thawed. If you freeze the tortellini, you’ll notice it’s texture becomes soggy and kind of gross when thawed and reheated. The half and half may curdle and separate when reheated as well, so avoiding both of these unpleasant scenarios is always a great idea.
