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.

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.

The key to good French onion soup is to cook the onions so long that they threaten to melt into a viscous, dark brown paste, à la Marmite. As has already been extensively reported in Slate, there are no shortcuts when you're caramelizing onions; it always takes at least an hour, usually longer.

Most French onion soup is topped with a Gruyère cheese crostini, while Oliver's recipe calls for cheddar. In summary, general onion soup recipes are seemingly more complicated, and the simpler French recipe sticks to classic flavors and doesn't allow much wiggle room for creativity.

Foods that have a great deal of acidity, like lemon juice, vinegar, white wine, and tomato puree, can help liven up the flavor of bland-tasting bone and other broths. "The acidity of these ingredients works to complement and enhance the broth's flavors, not mask it.

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

You can use a white wine, brandy or dry vermouth (or, depending on the recipe, red wine, Port, Madeira or Marsala, knowing they will leave some residual flavor). You can also try vinegars—apple cider, wine vinegar or even rice wine vinegar.

I also used a good whiskey instead of cognac as I didn't have cognac. I used a good Cabernet for the wine. I didn't add the raw onion as my husband can't eat raw onions. It is so worth the time to make it and more...

restaurants serve French onion soup in a Lion Head soup bowl made of porcelain, because of the style and also, because it is an oven-safe bowl.

What is the etiquette for eating French onion soup? ›

With such a soup, a knife is your friend, not your enemy. Using both the soup spoon and the knife, push the baked cheese against the rim of the cup or bowl and cut it gently with the knife. Once you've broken the cheese barrier, you can use the knife again to nudge bits of cheese onto the spoon.

While certain vegetables can work just fine added directly to simmering soups and stews (say, carrots and celery), other vegetables (onions, garlic, and the like) will almost always need at least a brief sweat in a fat-based liquid before adding the remaining ingredients.

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.

When you are sauteing onions to build flavor as a base for your dish (soup, tomato sauce, you name it), the yellow onion is your friend. That being said, white onions are a totally acceptable substitute for yellow, especially if you're cooking them.

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.

Infusing the soup with a richer taste is as easy as quickly sauteing crushed garlic before pouring the soup in. Some soft, buttery garlic sauteed in earthy olive oil is the perfect addition to enrich canned French onion soup.

Perk up a Bland Soup With Simple Pantry Staples

Add a splash of vinegar (any kind!), or a squeeze of citrus. Chances are, you could use a little more salt. Go ahead—it's ok. Salt perks up flat flavors and helps balance out bitter-tasting ingredients.

Onion soup, at its very essence, is nothing more than onions and water boiled together. Period, done, finished, everything added from that point on is pure opinion. Caramelizing the onions brings out sugars, and makes a more luxurious silky and sweet soup, adding flour gently thickens and provides body.
