French onion soup is one of my favorite comfort foods! The warmth and the rich taste always make me feel good when I eat it. And I think I know why – it has been prepared all over the world for thousands of years. For that matter, I had to (try to) make its keto variation!

But the dish as we know it today took shape in the 18th century. The story is rather funny and it shows that some wonderful foods are created by accident. It says that after a long day of hunting, King Louis XV returned to his lodge to find his cupboards practically empty. All he could find were onions, butter, and some champagne. He threw them into a pot, cooked and stirred for a while and served, making a lovely meal by chance.

When preparing onion soup It would be great if you can use homemade broth because it really makes a difference. But if you can’t, don’t worry! You can use store bought beef broth, but make sure you taste it first.

Original French onion soup is served with bread and covered with cheese. I took this into consideration and fat-head dough as a “cover” seemed like a logical solution. This fat-head dough I made a bit cheesier than usual. Though this tasted yummy,¬†next time I will try it with low-carb bread and cheese.

Considering that the onion in the “moderate” category of foods that are allowed on the keto diet, this recipe is something to be made for a special occasion. And it really is special. I recommend making this for your friends and family in the upcoming winter. Everybody knows there is nothing better than a home-cooked meal and this one will definitely charm your loved ones in a typically French way.
