How To Make the Best French Onion Soup

There are two essential components of a good French onion soup.

The first is the stock. Your soup will only be as good as the stock you are using. This soup traditionally is made with beef stock, though sometimes a good beef stock can be hard to come by and expensive to make.

If you use boxed stock, taste it first! If you don't like the taste, don't use it. (If you cook a lot of beef or beef roasts, save the scraps and freeze them to make a stock with later.)

The Secret Ingredient Is Time

The second most important element is to properly caramelize the onions. Caramelizing the amount of onions needed in this recipe will take at least 40 minutes. Caramelizing is a chemical process that occurs when the sugars in the onions reach a certain temperature.

This only happens after a long cooking time (the addition of a little extra sugar will help). The more caramelized, the deeper the color of the onions and the more flavor you'll get from them.

Alternatives To Wine

The recipe calls for dry vermouth or white wine as well as brandy, which is optional. If you prefer not to use any alcohol, many readers who made the recipe mentioned in the comments that they omit it altogether and it's still delicious.

Others mentioned adding some Worcestershire sauce at the end to give it an additional depth of flavor. If you omit the alcohol, you may want to add a tablespoon or so of Worcestershire, but it's not necessary.

If you do choose to omit the alcohol, use a half cup of the beef broth to deglaze the pan as instructed in Step 2 before adding the remaining stock in Step 3.

The Best Cheese To Use for French Onion Soup

Gruyere and Parmesan are the classics for French onion soup. However, if you don't have them, try these alternatives.

  • Gouda
  • Swiss
  • Fontina
  • Mozzarella

How To Store and Reheat This Dish

Store the soup—without the croutons—in an airtight container in the refrigerator for 3 to 4 days. To reheat, bring to a boil on the stovetop. The croutons are best when made fresh.

How To Freeze French Onion Soup

This soup—without the croutons—freezes well. Freeze the cooled soup up to 3 months. Defrost in the refrigerator and reheat by boiling on the stovetop. Make the croutons fresh.

French Onion Soup

Prep Time20 mins

Cook Time60 mins

Total Time80 mins

Servings4to 6 servings

Much of the success of this soup depends on the stock that you are using, and stock varies tremendously in its taste. Depending on your stock, you may need to bump up the flavor with some beef bouillon (we recommend Better Than Bouillon brand).

Ingredients

  • 6 large red or yellow onions (about 3 pounds)

  • 4 tablespoons extra virgin olive oil

  • 2 tablespoons butter

  • 1 teaspoon sugar

  • Kosher salt

  • 2 cloves garlic, minced

  • 8 cups beef stock, chicken stock, or a combination of the two

  • 1/2 cup dry vermouth or dry white wine

  • 2 bay leaves

  • 1 tablespoon fresh thyme leaves, a few sprigs of fresh thyme, OR 1/2 teaspoon dried thyme

  • 1/2 teaspoon freshly ground black pepper

  • 2 tablespoons brandy (optional)

  • 8 slices (1 inch thick) French bread or baguette

  • 1 1/2 cups grated Gruyere cheese

  • Sprinkling grated Parmesan cheese

Method

  1. Peel and slice the onions:

    Peel and thinly slice the onions from root to stem. There should be about 10 cups of sliced onions in total.

  2. Begin caramelizing the onions with olive oil and butter:

    In a 5 to 6 quart thick-bottomed pot, heat 3 tablespoons of olive oil on medium heat. Add the onions and toss to coat with the olive oil.

    Cook the onions, stirring often, until they have softened, about 15 to 20 minutes.

    Increase the heat to medium high. Add the remaining tablespoon of olive oil and the butter and cook, stirring often, until the onions start to brown, about 20 to 40 minutes. The amount of time will vary depending on your pot, stove, and onions.

  3. Sprinkle with the sugar, finish caramelizing, and add garlic:

    Sprinkle with sugar (to help with the caramelization) and 1 teaspoon of salt. Continue to cook until the onions are well browned, about 10 to 15 more minutes.

    Add the minced garlic and cook for a minute more.

  6. Season and add the brandy:

    Season to taste with more salt and add freshly ground black pepper. Discard the bay leaves. Add brandy if using.

  7. Toast the French bread slices:

    While the soup is simmering, line a sheet pan with parchment paper or foil and preheat the oven to 450°F with a rack in the upper third of the oven.

    Brush both sides of the French bread or baguette slices lightly with olive oil (you'll end up using about a tablespoon and a half of olive oil for this).

    Put in the oven and toast until lightly browned, about 5 to 7 minutes. Remove from oven.

    Turn the toasts over and sprinkle with the grated Gruyere cheese and Parmesan. Return to oven when it's close to serving time and bake until the cheese is bubbly and lightly browned.

  8. Serve:

    To serve, ladle soup into a bowl and transfer one cheesy toast onto the top of each bowl of soup.

    Alternatively, you can use individual oven-proof bowls or one large casserole dish. Ladle the soup into the bowls or casserole dish. Cover with the toast and sprinkle with cheese. Put into the broiler for 10 minutes at 350° F, or until the cheese bubbles and is slightly browned.
