Who wants homemade onion soup to warm up?

The origin of onion soup

According to legend, Louis XV is the originator of onion soup, as we eat it today. One night, while staying in his hunting lodge, the king set out in search of provisions to eat. Finding only onions, butter and champagne at his disposal, he ventured to make a soup. In the end, he liked the result so much that he made it one of his favorite meals.
Subsequently, onion soup became established at court, then popularized among the lower classes. Having become a poor man’s dish, simple but nourishing, it was particularly appreciated for its ability to mask the hints of alcohol. It is thanks to this that it acquired the nickname “drunkards’ soup”.

Note, however, that this story is frequently called into question by historians. Indeed, most believe that there is little chance that the king had to prepare his meal himself. Others object that Louis XV being reputed to be an excellent cook, the thing is entirely plausible. He was particularly famous (in addition to his title) for his “fanatic” omelettes, pâtés de mauviettes (a kind of lark) and his basil chicken. It would therefore be possible that Louis XV could have made this famous onion soup!

True or not, we will probably never know the truth. Still, this story, pleasant to tell, will surely interest your guests.

The trick that changes everything

For a flavorful soup, it is important that the onions are finely sliced ​​and well caramelized. First of all, because the smaller a food is cut, the more its flavors will be diffused. Have you ever noticed that this type of cutting makes food tastier? This is thanks to the fact that the finer a food is cut, the greater its surface area will be, therefore the more its aromas will be released. Moreover, we call this the principle of the exchange surface. Long story short: the more flavor you want, the smaller you cut!

Also, it is important that your onions are nicely browned before deglazing them with the broth. This will bring out their flavor to the fullest. Remember that a clear onion soup is a bland soup. A real onion soup must have a pretty amber color, obtained by fairly thorough coloring. Be careful, do not let the onions burn, this would give an unpleasant taste to the broth. So cook everything over low heat, checking regularly.

You now know all the secrets of this light and comforting recipe.
