French onion soup

Guide de la bonne cuisine is one of my favourite French (old) cookbooks. It was written in the 19th-century, but this book contains loads of recipes that you will still find unchanged in the modern kitchen. French onion soup is the perfect comfort food after a long cold day or when you want something extra for lunch.

There are a few great stories about the history of onion soup. One of the stories is that Louis XV came home after a long day spent outdoors only to find an empty pantry. All he had were onions, butter, and champagne. He supposedly threw everything in a pan and discovered this soup.

Another story is also about Louis XV and his family. This time, Queen Marie’s father, Duke of Lorraine, stayed in a hotel where Nicolas Appert made this soup for him during a trip to his daughter. He loved the soup so much that he wanted to take the recipe with him to his daughter’s palace. In his cookbook, Appert gave this recipe a royal name: Onion soup a la Stanislas. Wherever this soup comes from, we have been enjoying onion soup for hundreds of years.

This recipe is so easy to make. Slice the onions, caramelize them in butter and add beef stock. You could also add a glass of white wine and thyme if you wish. I grilled the bread and cheese before adding it to the soup. Another way to serve onion soup is to ladle the soup in your bowl, add the bread, cover it all with cheese and put everything in the oven. Both ways taste great.
