Since traveling to France recently and having French Onion soup, I was seriously craving some. This recipe is the closest thing to being to France 🙂

French Onion Soup Ingredients

The ingredients for the savory soup are simple. Lots of onions, garlic, butter, oil, beef broth and chicken broth.

I used White wine vinegar, cooking sherry and some dried herbs. The original recipe calls for Vermouth or Dry White wine.

That is it!

6 medium yellow onions (sliced thinly) I used 5 large and one medium

4 Tbsp Olive oil

2 Tbsp butter

1 tsp sugar

Kosher salt

2 cloves garlic, finely chopped

4 Cups beef broth

4 Cups Chicken broth

1/4 Cup White wine vinegar

1/4 Cup Cooking sherry

Bay leaf

1 1/2 tsp herbs de Provence (but you could use Thyme)

1 tsp Webers Beer Can chicken seasoning

Slices of French baguette

1 Cup grated gruyere cheese

1/2 Cup grated parmesan cheese

Cooking the French Onion Soup

Once your olive oil is hot, add your sliced onions to soup pot and mix well with the oil.

Cook for about 15 minutes. Stirring frequently until onions begin to be transparent.

The longest part of this recipe is waiting for your onions to get to a golden color but worth the wait!

Once they are softened you can add the butter. Cook for another 10 – 15 minutes and then sprinkle with sugar.

This will help the onions to get golden faster. Add in the garlic and cook one minute longer.

Deglaze the onions

Now that the onions are golden in color it is time to deglaze the pot. Add the white wine vinegar and cooking sherry all at once. Stir the pot and get any tid bits from the sides and bottom of the pot.

This adds in more flavor.

Beef and chicken broth

It is time to add both broths to the soup pot. You can use only beef broth as most French onion soup is only made with beef broth. I used half beef and half chicken.

Add in the bay leaf. Simmer for about 30 minutes.

Season with salt and pepper and remove the bay leaf. You can add another little glug of cooking sherry if you think it needs a little more flavor.

Toast the baguettes

Slice your French baguettes into 1″ slices and brush with olive oil. Toast on a cookie sheet with parchment paper at 450 degrees.

French Onion Soup Ingredients

  • 6 medium yellow onions sliced thinly I used 4 large and one medium
  • 4 Tbsp Olive oil
  • 2 Tbsp butter
  • 1 tsp sugar
  • Kosher salt
  • 2 cloves garlic finely chopped
  • 4 Cups beef broth
  • 4 Cups Chicken broth
  • 1/4 Cup White wine vinegar

  • 1 Cup grated gruyere cheese

Sliced baguettes

    Instructions

    Caramelize onions

    • In a 5 to 6 quart 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 15 more minutes.

    • Sprinkle with sugar (this will help to brown the onions better) plus 1 teaspoon of salt. Cook until the onions are well browned, about 10 to 15 more minutes.

      Add the seasonings at this point.

      Tip- I used a small burner at first and switched to a larger burner and the onions finally started to turn golden in color.

    • Add the minced garlic and cook for a minute more.

      Tip- Don't overcook the garlic as it will turn bitter.

    Deglaze the onions

    • Add the white wine vinegar and cooking sherry to the pot and scrape up the browned bits on the bottom and sides of the pot, deglazing the pot as you go.

    • Add the stock, bay leaves.

      Bring to a simmer, cover the pot and lower the heat to maintain a low simmer. Cook for about 30 minutes

    • Season to taste with more salt and add freshly ground black pepper. Discard the bay leaves.

    Toast the French baguette slices

    • While the soup is simmering, line a sheet pan with parchment paper preheat the oven to 450°F

      Brush both sides of the French bread or baguette slices lightly with olive oil

      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.

      Ladle soup into bowls and add one piece of the cheesy toast.

    FAQs

    How can I increase 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.

    What is the difference between onion soup and French onion soup? ›

    What is the Difference Between Onion Soup and French Onion Soup? French onion soup is always made with beef stock. Other onion soups can be made with chicken, vegetable, or beef stock. Additionally, French onion soup typically contains wine or sherry, which isn't typical or necessary in other onion soups.

    Why do you put baking soda in French onion soup? ›

    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.

    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.

    Why is my French onion soup so bland? ›

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

    How can I deepen my soup flavor? ›

    Why do French people eat French onion soup? ›

    The Onion Soup, a traditional and warming dish

    It has even become a trendy dish that tourists are eager to try to experience French gastronomy. However, onion soup is in fact not part of French people's daily meals. It was originally meant to be eaten after a family reunion in the middle of the night to cure hangovers

    Why is French onion soup so expensive? ›

    First, French onion soup calls for a ton of onions. While onions aren't expensive, there's a lot of labor involved in halving, peeling, and slicing 10, 12, 50, or one billion onions (I don't know how much soup you make).

    Why does French onion soup taste so good? ›

    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.

    How do you make French onion soup less bland? ›

    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. A shot of brandy at the end helps too.

    What is the best wine for French onion soup? ›

    Use Dry White Wine

    I have tried several different wines for this recipe and I find dry white wine to be the best.

    How do you thicken French onion soup? ›

    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.

    What is impolite to do in France when eating? ›

    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.

    Is French onion soup good for your gut? ›

    Onions are a great source of soluble fibre and therefore a good prebiotic; food for the good gut bacteria. Optimal gut health is crucial for weight loss and this delicious soup provides great nutrients to help boost weight loss as part of a weight management programme.

    Why did Vikings eat onion soup? ›

    Wounded Viking warriors ate strong onion soup.

    How to doctor up canned French onion soup? ›

    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.

    What can I add to my soup to make it more flavorful? ›

    Go Bold. A punch of flavor at the end of cooking can make your soup a standout. Mix herbs like parsley, thyme, and oregano, or spices such as cumin, coriander, and cardamom, into some olive oil, and let it infuse for at least an hour or two. Pour it over soup just before serving.
