For a deeper flavor, consider using a combination of sweet and yellow onions. If you don't have Port wine, a dry Sherry or Madeira can be used as a substitute. For a vegetarian version, use vegetable broth instead of beef stock. To prevent the bread from becoming soggy, you can lightly toast it before adding it to the soup. Be careful when broiling, as the cheese can burn quickly. Keep a close eye on the crocks.
