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

If you don't have homemade beef stock, the recipe's suggested homemade or store-bought chicken stock substitutions are better than most store-bought beef stock. Asian fish sauce, cider vinegar, and sherry add depth and complexity to the broth.

Instant Pot SOUP Setting (SOUP/BROTH BUTTON) The default Instant Pot soup setting is pre-programmed to set the pot to cook at HIGH pressure for 30 minutes. The soup program brings the contents of the pot to a slow simmer and results in a clear broth due to lack of boiling motion.

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.

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.

The underlying flavor of this soup is the deep umami flavor of the caramelized onions. If you rush this process, the result will be a bitter charred flavor, and if you underestimate and skip this process the flavor will be nowhere near as deep or complex.

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.

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.

I usually make the soup a day ahead; it seems to taste even better that way! If you don't have French onion soup bowls (see photo below), check your local thrift shop or keep an eye out at garage sales. Arrange bread cubes on a baking sheet and lightly toast in a 250F oven until just starting to get crunchy.

Got a soup that tastes a little bland and unexciting? Add a splash of vinegar (any kind!), or a squeeze of citrus. Chances are, you could use a little more salt.

If the soup is too sweet, add some vinegar. If you would like a little more depth, add a splash of red wine. I like the onion-to-liquid ratio with 6 cups of water. But if you'd prefer a slightly more delicate soup, add an additional 1 cup/240 milliliters water or to taste.

Caramelized onions are generally the star of the dish's flavor profile, but there's no shame in adding a little extra seasoning to help your soup taste extra indulgent. Seasonings can complement the flavors of the soup's other ingredients, adding some subtle flavoring without overpowering the dish.

Brown or Sear the Meat

If you are adding meat to a soup, sear or brown it in a sauté pan before you add it to the soup. This adds a deeper savory flavor to the whole soup. This trick is especially useful for things like chicken and sausage, which can sometimes get bland and rubbery while floating in a brothy soup.
