French onion soup, with its rich, savory broth, caramelized onions, and cheese-laden crouton topping, is a culinary masterpiece enjoyed worldwide. But what exactly is this comforting classic called in its country of origin, France? The answer, while seemingly simple, offers a fascinating glimpse into French language and culinary tradition.
The French Name: *Soupe à l’oignon gratinée*
The most common and widely accepted name for French onion soup in France is soupe à l’oignon gratinée. This translates directly to “onion soup gratinéed” or “onion soup with a gratinated topping.” The key word here is “gratinée,” which refers to the browned, crusty layer of cheese that blankets the soup.
The term emphasizes the signature element that distinguishes French onion soup from simpler onion-based soups. The “gratinée” part signifies the bubbling, golden-brown cheese, usually Gruyère, Emmental, or Comté, that’s melted over a slice of bread or crouton, creating a delightful contrast of textures and flavors.
Variations and Regional Nuances
While soupe à l’oignon gratinée is the most standard term, you might encounter other variations depending on the region or the specific preparation of the soup.
*Soupe à l’oignon*
This simply translates to “onion soup.” While technically any soup made with onions could fall under this category, it’s often used as a shorter, less formal way to refer to the classic French onion soup. However, be aware that ordering simply “soupe à l’oignon” might not always guarantee you’ll receive the gratinéed version, so it’s always best to clarify.
Regional Variations in Ingredients
Across France, subtle variations exist in the preparation of soupe à l’oignon gratinée. Some regions might favor a particular type of cheese, while others might add a splash of wine or brandy to the broth for added depth of flavor. These regional tweaks, however, don’t typically result in a different name for the dish.
The Importance of “Gratinée”
The word “gratinée” is crucial in understanding the essence of the dish. It speaks to the technique of browning the cheese under a broiler or salamander, creating a crisp, flavorful crust that’s integral to the overall experience. Without the “gratinée” element, you’re simply having onion soup, not the iconic French onion soup that’s so beloved.
The caramelization of the onions is also a key element, which is usually developed by slow cooking them with butter until they release their sugars and turn a deep, rich brown. This process imparts a sweetness that balances the savory broth and the sharpness of the cheese.
The History of French Onion Soup
French onion soup has a surprisingly humble history, tracing its origins back to Roman times. Onions were a staple food, and onion soup was a common dish for the poor. The modern version of soupe à l’oignon gratinée is believed to have evolved in the 18th century, with the addition of beef broth and the signature gratinéed topping.
Legend has it that King Louis XV, upon returning to his hunting lodge late one night with nothing but onions, butter, and champagne, invented the soup out of necessity. Whether this is true or not, it adds to the soup’s allure and romantic association with French cuisine.
Ingredients and Preparation
While variations exist, the core ingredients for soupe à l’oignon gratinée remain consistent:
- Onions: Usually yellow or white onions, thinly sliced.
- Butter: Used to caramelize the onions.
- Beef broth: Provides the savory base for the soup.
- Dry white wine or brandy: Adds depth of flavor. Optional.
- French bread or croutons: Provides a base for the cheese.
- Gruyère, Emmental, or Comté cheese: Used for the gratinéed topping.
- Salt and pepper: To season.
The soup is traditionally prepared by slowly caramelizing the onions in butter until they are a deep golden brown. The beef broth (or vegetable broth for a vegetarian version) is then added, along with the wine or brandy (if using), and the soup is simmered. The bread or croutons are placed on top of the soup in oven-safe bowls, and the cheese is generously layered over the bread. The bowls are then placed under a broiler or salamander until the cheese is melted, bubbly, and golden brown.
Serving and Enjoying *Soupe à l’oignon gratinée*
Soupe à l’oignon gratinée is typically served as a starter or a light meal. It’s best enjoyed hot, straight from the oven, with the cheese still bubbling and the aroma filling the air. The contrast of the savory broth, the sweet caramelized onions, and the rich, melted cheese creates a truly satisfying culinary experience.
It’s often enjoyed during colder months, offering a warming and comforting meal. However, its delicious flavor and satisfying texture make it a popular choice year-round.

While other variations exist, this is the term you’ll most likely encounter when ordering the dish in a French restaurant or discussing it with French speakers.
It is important to note that simply saying “Soupe à l’oignon” (onion soup) is also acceptable and understood, but “Soupe à l’oignon gratinée” specifically highlights the gratinéed cheese topping, which is a significant and defining characteristic of the soup as it’s widely recognized and enjoyed. Using the full term leaves no room for ambiguity.
Are there any regional variations in the name of French onion soup in France?

In certain regions, you might hear a more colloquial or shortened version of the name, but the core components – “soupe,” “oignon,” and “gratinée” – will generally remain present. Regional dialects and patois may influence the exact phrasing, but the essence of the name referring to onion soup with a gratinated cheese topping will be consistently understood.
Does the term “French Onion Soup” exist in the French language?
The term “French Onion Soup” as a direct translation is not commonly used by French speakers when referring to the dish in France. While they would understand what you mean if you used this phrase, it’s not the natural way they would refer to it amongst themselves. It sounds more like a foreign translation than a native French term.
Instead, they would typically use “Soupe à l’oignon gratinée” or simply “Soupe à l’oignon,” as these are the standard and accepted terms within French culinary culture. Using the English translation in France might be perceived as slightly odd, even though the meaning would be clear.
What does “gratinée” refer to in “Soupe à l’oignon gratinée”?
The term “gratinée” in “Soupe à l’oignon gratinée” refers to the layer of melted cheese that is browned and crusty, creating a golden, flavorful topping. This is a crucial element of the soup, distinguishing it from a simple onion soup. The cheese is typically Gruyère, known for its excellent melting properties and nutty flavor.
The “gratinée” process involves placing the soup under a broiler or using a salamander (a specialized kitchen broiler) to melt and brown the cheese. This creates a textural contrast between the rich, savory broth and the crispy, cheesy topping, which is a key characteristic of the dish and contributes significantly to its overall appeal.
Is there a difference between “Soupe à l’oignon” and “Soupe à l’oignon gratinée”?
While both terms refer to onion soup, there is a subtle but important difference. “Soupe à l’oignon” simply means “onion soup,” while “Soupe à l’oignon gratinée” specifically denotes onion soup that has been gratinated with cheese, typically Gruyère.
Therefore, “Soupe à l’oignon gratinée” is a more specific and descriptive term. While you might be served “Soupe à l’oignon gratinée” if you order “Soupe à l’oignon,” it’s always best to use the full term if you want to ensure you receive the classic version with the cheesy topping.
What are the key ingredients that differentiate French onion soup in France?
The key ingredients that define French onion soup in France are onions (typically yellow or white), beef broth (or sometimes vegetable broth), bread (usually a baguette or crusty bread), and Gruyère cheese. The slow caramelization of the onions is absolutely essential for developing the soup’s rich, sweet, and savory flavor profile.
Furthermore, the bread is used as a base to soak up the broth and provide a contrasting texture, while the Gruyère cheese is melted on top to create the signature “gratinée” crust. These ingredients, combined with the specific cooking techniques, are what truly characterize and distinguish French onion soup in France from other variations.
How would I correctly order French onion soup in a French restaurant?
To order French onion soup correctly in a French restaurant, the most straightforward and polite approach is to say “Je voudrais une Soupe à l’oignon gratinée, s’il vous plaît.” This translates to “I would like a gratinated onion soup, please.” This ensures clarity and specifies the traditional version with the melted cheese topping.
Alternatively, you could say “Je prendrai une Soupe à l’oignon gratinée, s’il vous plaît” (“I will have a gratinated onion soup, please”). Both phrases are grammatically correct and commonly used in French restaurants. Using “s’il vous plaît” (please) is essential for politeness in any interaction.
