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.

Fix a bland onion soup by using supermarket broth and mild white onions, tasteless oil for sauteeing, stale plain white bread instead of croutons, and mild white cheese. Start by reducing the broth. Simmering out some water will intensify the flavor of the broth. Once you get it to the right point, add some salt.

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.

If the onions are not cooked long enough or over low heat, they won't develop the sweet and rich flavor that is characteristic of this soup. Lack of seasoning: Seasoning is crucial in any dish, and French onion soup is no exception.

Herbs and sources add flavor, aroma, and intensity to the soup broth. You can pick fresh or dried herbs like basil for tomato-based soups or fresh parsley for clear broths. You may also add more spices like turmeric, ground ginger, ground paprika, or nutmeg for a touch of spice and color to your soup broth.

Caramelizing the onions brings out sugars, and makes a more luxurious silky and sweet soup, adding flour gently thickens and provides body.

You float a piece of toasted bread on top of the soup … lots of onions will keep it afloat … then the cheese goes on top of that.

A few reasons could be that you sliced them too thick or too thin. You haven't cooked them long enough. Your heat isn't at the right temp, use between medium and medium-low.

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).

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.

Why do you put lemon juice in soup? ›

But as the publication explains, lemon juice adds more than just tartness. For chicken soup in particular, lemon juice balances out the more rich and savory flavors, adding an overall brightness to the taste.

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.

For the onion soup, Julia Child says the onions should cook for 25-30 minutes and be “a dark walnut color”. So I'm stirring my onions, watching as they go from off-white to light brown and then to walnut, a process that does end up taking 30 minutes. Here's the recipe for 4 servings: 1/2 stick unsalted butter.

If you don't have any bay leaves on hand, there are a couple of other seasonings that could still provide a similar, herby taste to upgrade the flavor of your French onion soup. Oregano and thyme can both make for suitable swaps for bay leaves. Both are boldly flavored and a little bitter, similar to bay leaves.

The truth is French Onion soup is usually better the next day. So if you can make it ahead of time, that's to your advantage. It will still be delicious either way. To store any leftovers, place the soup in an airtight container and refrigerate for up to a week.

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.

Use fresh vegetables, high-quality meats or broth, and fresh herbs to add depth of flavor. Add acidity: A squeeze of lemon or lime juice, a dash of vinegar, or a splash of wine can brighten the flavors of a soup and make it taste more complex.

A squeeze of citrus, a dollop of yogurt or a drizzle of cream, a dusting of cheese or a good chile powder, a sprinkling of some herbs or croutons — all can take a perfectly fine soup into the realm of the delectable. Even a spiral of good olive oil to finish and some coarse sea salt can do wonders.
