How come French onion soup is such a big deal in France? Well, we can't mess with tradition — this is one of the best dishes every restaurant has been making on a daily basis for decades, and it's judged by its level of preparation. I've lived in Paris for 7 years. I arrived as a student and stayed a few years more. It's a magical city that really gets to you. One of the things I miss the most is the French onion soup I used to have at 'La Jacobine', a small restaurant with an amazing silky, heavy-textured onion soup covered with a lot of cheese — perhaps the best French onion soup I've had. In my opinion, a good onion soup is the essence of French bistro food. It's full of deep flavors that make you wonder how exactly they were created from an onion. Onion soup is a great way to see the transformation of a single ingredient — from its raw shape to a bronze form that builds a strong emulsion and turns into something completely different, strong in color and taste. This soup has two dominant flavors: the onions and the beef broth. Don't try to make this soup with chicken broth — it'll lose that heavy, silky taste that comes from the meat stock. french onion soup french onion soup french onion soup The flavor comes from the time the onions spend in the pot, caramelizing all the sugars stored in them, with the butter creating a magical emulsion. This is the base of the soup, and it'll determine whether the onion soup ends up with a strong flavor or a weak one — so put your effort into stirring those onions. It's worth it. french onion soup

Why should I put so much effort into this french onion soup?

Method

    Starting the soup· 25 minutes

    Place a large sauce pan on high heat. Melt the butter, add the onions and stir, at first it will look like its too much onions but don't worry it will decompress in a few minutes. from this point we will keep stirring the onions continually not letting them burn just making them caramelize, we will push them to the extreme.

Questions & answers

Can I make this soup without gluten?
Yes, just skip the flour entirely — the recipe calls it out as optional for gluten-free cooks.
Can I swap the beef broth for something vegetarian?
The recipe calls specifically for beef broth, so swapping it would change the flavor profile significantly — stick with it if you want that classic French onion depth.
What bread works best for the topping?
The recipe doesn't specify a type, so use whatever sturdy slices you have — you want something that can hold up to a drizzle of olive oil and a shower of Parmesan without falling apart in the soup.
Do I really have to stir the onions for 25 minutes straight?
Yep, keep at it — constant stirring is what caramelizes them without burning, and that deep golden color is the whole flavor base of this soup.
Can I use all yellow onions instead of mixing in a red one?
The recipe uses a mix of yellow and red onions, so swapping to all yellow will work but you'll lose a bit of the flavor complexity that the red onion adds.
