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.

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.

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.

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.

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

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.

Burned onions – result in bitter soup. Be careful to not burn the onions/cook them until they are too dark in color – you don't really need to cook them until they are dark brown – golden brown/light brown is enough.

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.

While salt can be added to balance out this richness, using lemon instead will actually be more effective. This is because the acid from the lemon cuts through the fat and balances out the spices. Using lemon zest on top of each bowl is also a great garnish that provides a zesty punch in every bite.

French onion soup is traditionally served in lionhead bowls, which are deep but not very wide porcelain bowls. Here are four reasons why these bowls are perfect: Plenty of soup. Even as the bread on top starts to soak up some of the soup, there's still plenty left underneath.

Can I use chicken broth instead of beef broth in French onion soup? ›

It is better to use chicken or vegetable broth rather than sub-standard beef broth. Best to use low salt and add salt if required. 4. Bread - The idea with the recipe is that you can use a spoon to cut through the bread into the soup to eat it (see video).

Onions: You can use white, yellow or red onions for French onion soup. But to make it the classic way, you will need 5-6 large yellow onions, peeled and thinly sliced. Butter: The tastiest (French) way to caramelize those onions.

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.

Eating with your hands is considered impolite, so make sure to tuck into that steak frites with your knife and fork. Notable exceptions include bread and certain dishes including asparagus. One thing you may have noticed in France is people do not cut their salads. Do so, and you might receive a few funny looks.

The food writer Waverley Root comments that the origins of French onion soup may lie in Alsace, although the dish is popular throughout France and "apparently no region lays particular claim to it". Onion soups from other regions include the tourain from Quercy-Périgord and the ouliat from the Béarn.

"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.

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.

You can extract a clean, strong broth from a combination of water and several pantry ingredients. It's all about layering powerful flavor-enhancers that you probably already have on hand—bacon, tomato paste, herbs, peppercorns, a Parmesan rind, and, of course, kosher salt.
