The Traditional Name of French Onion Soup in France
French onion soup has a history that dates back centuries, but in France, it’s known by a simpler, more traditional name.
What Do the French Call French Onion Soup?
If you visit a restaurant in Paris and ask for French onion soup, the waiter might give you a puzzled look. That’s because in France, this dish is called “Soupe à l’Oignon”, which translates simply to onion soup.

Why Don’t the French Call It “French Onion Soup”?

- A name given by foreigners – English speakers added “French” to highlight its origins.
- In France, it’s just “onion soup” – Since it’s an everyday dish, there’s no need to specify that it’s French.

Common Mistakes to Avoid When Making French Onion Soup
Even though Soupe à l’Oignon is a simple dish, there are common mistakes that can affect the final result. If you’ve been wondering, what is French onion soup called in France?, it’s important to know that authentic French preparation plays a big role in its flavor and texture. Here’s what to watch out for when making this dish at home.
1. Rushing the Onion Caramelization
Why This Is a Mistake
Caramelizing onions properly is the heart of a great French onion soup. Many people rush this step, resulting in onions that are undercooked, bitter, or lacking depth of flavor.
How to Do It Right
- Cook onions slowly over low heat for at least 30–40 minutes.
- Stir occasionally to prevent burning while allowing them to turn a deep golden brown.
- Add a pinch of sugar to help with caramelization if needed.
Patience is key—perfectly caramelized onions make all the difference!
2. Using the Wrong Type of Broth
Why This Is a Mistake
Some recipes call for chicken or vegetable broth, but these options lack the rich, deep flavor that traditional Soupe à l’Oignon is known for.
How to Do It Right
- Use high-quality beef broth for the best depth of flavor.
- If you prefer a lighter version, opt for homemade vegetable broth rather than store-bought.
- Simmer the soup long enough to infuse all the flavors together.
A good broth is essential to achieving the restaurant-quality taste of authentic French onion soup.
3. Skipping the Baguette and Cheese Topping
Why This Is a Mistake
French onion soup isn’t complete without the classic gratinée topping—toasted bread and melted cheese. Skipping this step turns the dish into a regular onion soup, missing out on its signature texture and taste.
How to Do It Right
- Use thick slices of a French baguette to hold up against the broth.
- Choose a melting cheese like Gruyère, Comté, or Emmental for the perfect golden crust.
- Broil the soup just before serving to create that irresistible bubbly, crispy top layer.
This final touch transforms a simple soup into an elegant French classic.
4. Not Serving the Soup Immediately
Why This Is a Mistake
Once the soup is broiled with its cheesy topping, letting it sit too long can cause the bread to become soggy and the cheese to harden.
How to Do It Right
- Serve the soup straight from the oven while the cheese is still hot and bubbly.
- If making ahead, reheat the soup first, then add the bread and cheese before broiling.
By avoiding these common mistakes, you’ll be able to prepare the perfect bowl of French onion soup every time.
Now, let’s go over some final thoughts and takeaways about this delicious dish.
