How do you deepen the flavor of French onion soup? ›

A few sprigs of thyme and a bay leaf elevate the soup even more, but I take it a step further, adding a splash of fish sauce for complexity and depth—don't worry, it won't taste fishy—and a hit of cider vinegar to balance some of that oniony sweetness.

What Is French Onion Soup? French onion soup, or soupe à l'oignon gratinée, is a classic French dish made with caramelized onions and beef stock or broth. The soup is topped with bread and cheese, then gratinéed to rich, gooey perfection. It's traditionally served in a ramekin or a ceramic crock with a handle.

Although onions were plentiful and affordable by the poor, a medieval recipe in Le Ménagier de Paris, published in 1393, includes among its ingredients ginger and saffron – rare and expensive spices – making this version of the dish one for wealthy households.

What is the Difference Between Onion Soup and French Onion Soup? French onion soup is always made with beef stock. Other onion soups can be made with chicken, vegetable, or beef stock. Additionally, French onion soup typically contains wine or sherry, which isn't typical or necessary in other onion soups.

The caramelized onions for this soup cook more quickly due to a pinch of baking soda but still have that deep, slow-cooked flavor. Topping the soup with hot, cheesy toasts prepared while the soup simmers, eliminates the need to bake the soup in specialty French onion soup bowls.

Soaking the onions in cold water for 10 minutes before cooking can help to reduce the unpleasant taste and smell. Additionally, adding a pinch of sugar to the cooking onions can also help to reduce their pungent flavor.

Bread: I use toasted slices of French baguette rubbed with a bit of fresh garlic to make them extra delicious before adding them to my soup. It's the best! Cheese: The best cheese for French onion soup is Gruyère. It melts beautifully and tastes earthy and nutty, which works nicely with the savory soup base.

THE ICONIC FRENCH ONION SOUP!

And yet, the soup itself is made with very few core ingredients: butter, onions, flour and stock/broth. The magic is in the caramelisation of the onions, cooked slowly for at least 40 minutes.

French onion soup is the ultimate comfort food. Onions get slowly cooked until sweet and caramelized, then simmered in rich broth until they're practically falling apart. To finish it off, toasted bread is added to give it that lovable crisp-gone-soggy texture and a generous amount of Gruyère cheese is melted on top.

The Onion Soup, a traditional and warming dish

It has even become a trendy dish that tourists are eager to try to experience French gastronomy. However, onion soup is in fact not part of French people's daily meals. It was originally meant to be eaten after a family reunion in the middle of the night to cure hangovers…

What is a fun fact about French onion soup? ›

Its history

A legend has helped to restore the image of this soup: it is said that while King Louis XV slept in his hunting lodge, he woke up because of a nocturnal craving. He would then have made a soup from what he had on hand: onions, butter and champagne.

Onions are a great source of soluble fibre and therefore a good prebiotic; food for the good gut bacteria. Optimal gut health is crucial for weight loss and this delicious soup provides great nutrients to help boost weight loss as part of a weight management programme.

First, French onion soup calls for a ton of onions. While onions aren't expensive, there's a lot of labor involved in halving, peeling, and slicing 10, 12, 50, or one billion onions (I don't know how much soup you make).

The easiest way to thicken your French onion soup is with flour. You can also use cornstarch if you don't have any flour. Remember to never add the flour or cornstarch directly to the soup – otherwise you run the risk of it clumping.

The classic French onion soup gets its name from its country of origin: France. After making its debut in the 18th century, it has become a national treasure. During ancient times (and still today), onions were cheap and easy to grow, and hence, readily available.

Most likely it could be from not caramelizing the onions long enough, as this is crucial for flavor development. Also, be sure to use a good quality broth and season the soup properly with salt and pepper. You can try adding a splash of balsamic vinegar or Worcestershire sauce for a boost of flavor.

If you don't add enough salt, pepper, or other herbs and spices, the soup may taste bland.

Some fresh rosemary or thyme brings a woody, peppery taste to the soup, complementing the umami flavor of the beef stock. With a splash of balsamic vinegar and green onions or fresh basil as a garnish, the canned soup is transformed from a grocery store original into a gourmet dish.

"If your broth is lacking in savory richness, try adding roasted onion, tomato paste, mushrooms, seaweed, soy sauce, or miso. These ingredients add umami flavor and depth to broth," she says.
