Easy French Onion Soup Recipe (Seriously, The Only Recipe You Need!) (2024)

FAQs

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 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.

Lack of seasoning: Seasoning is crucial in any dish, and French onion soup is no exception. If you don't add enough salt, pepper, or other herbs and spices, the soup may taste bland. Weak broth: The quality and intensity of the beef broth used in the soup can greatly impact its flavor.

Wine is optional to deglaze the pan and add flavour to the soup. I recommend a dry white or red wine, such as a good quality Pinot Grigio/Gris, Sauv Blanc, Sémillon, Chardonnay, Merlot or Pinot Noir. Generally, if you can't drink it, don't cook with it.

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.

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.

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 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…

Get the oven to 400 degrees while you prepare the onions: Cut down through the poles of each onion, down through the root end into and through the stem end. Peel each half, keeping the flesh tethered at the root end. Slice 1/4-inch thick longways, pole-to-pole, using a mandolin if you have one.

What is the etiquette for eating French onion soup? ›

Yes, a knife! While many people assume that knives should be kept away from soups, French onion soup is the exception. A knife is invaluable for cutting through the layer of cheese and bread that crowns the bowl.

Broth: You can use chicken broth or beef broth to make French onion soup. We've tried all combinations (including using half chicken and half beef broth) and have loved them all.

"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.

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.

The sweetness can be balanced by adding some dry wine or vinegar. Taste as you go and don't overdo it. A little salt will balance it too, but don't forget that the grated cheese you will top it with is salty.

Submerge Them in Cold Water

Soak them for at least 15 minutes (longer is even more beneficial), properly drain, and eat away! Submerging them in cold water takes away that intense, sharp bite from the raw onion. The cold water helps the enzyme that causes onions to have their pungent flavor to leach out.
