French Onion Soup is a creamy bowl of comfort food. It may be a labor of love to make, but it is worth every delicious bite!
Hello Reader! I try my hardest to research recipes as best as I can before posting to ensure I am representing each culture correctly. If this recipe is from your country and I have made a mistake or you have suggestions for how to make it more authentic, I would love to hear! Please leave a comment below letting me know what should be different, and I will rework the recipe. It is always my intention to pay homage and respect to each cultural dish that I cook. Thanks for reading!
It takes just the right combination of high-quality ingredients and patience to make the most perfect bowl of French Onion Soup.
This classic French soup starts with butter and delicious, slowly cooked caramelized onions. The onions are then covered with a delicious, rich beef stock, seasoned with a splash of white wine.
Of course, the soup would not be as popular as it is without that perfect single layer of crusty toasted bread covered in gooey melted cheese on top.
Each bite of French Onion Soup is truly something special!
While all of these ingredients are simple enough to find, putting them together in just the right way can be tricky. Move too fast and you will easily burn your onions. Use the wrong bread and it may end up soggy. The wrong cheese could end up rubbery.
This classic French onion soup recipe is designed for when you have a little time to slow down, enjoy being in the kitchen, and make yourself a dish that is truly worth the effort.

Recipe Origins
There are a couple of different stories about how the rich flavor of French Onion soup was developed. A simple onion soup may have been enjoyed for centuries in Rome, but the French onion soup as we know it today is thought to have come from King Louis XV’s family.
One story is that King Louis XV himself was the inventor of the dish. After returning to his home after a long day of hunting, he discovered there was nothing to eat in the home but butter, onions, and champagne.
These simple ingredients were combined and French onion soup was born!
Another story goes that a chef named Nicolas Appert was working at a hotel called La Pomme d’Or in Châlons-en-Champagne when King Louis’s father-in-law, the Duke of Lorraine, stopped in.
After trying just a few bites of Appert’s creation, the Duke of Lorraine rushed to the kitchen to learn how to make it. He shared the dish with his daughter and son-in-law when he arrived in Versailles.
When Appert eventually wrote down his recipe in a cookbook, he dedicated it to the Duke of Lorraine.

How To Make This Recipe
Step One: Caramelize the Onions
Add a large pot or Dutch oven to your stove over medium heat. Add the butter to the pot and allow it to melt. Then, add the onions.
Stir the onions in the pot until they start to really whither and brown. You can add extra butter if you think it’s necessary. This step could take anywhere from 30-60 minutes depending on the size of your onions, the type of pot you use, and the heat level you are using.
Once the onions have started to brown, add 1 tbsp granulated sugar and stir for another 20-30 minutes until the onions caramelize.
Step Two: Make the Broth
Once the sweet caramelized onions are ready, add the all-purpose flour and stir for 30 seconds until the onions are coated.
Add ¼ cup of dry white wine to deglaze the pan. Stir for a few seconds to scrape up any browned bits on the bottom of the pan. Continue sauteeing until the wine cooks down.
Once the wine is gone from the pot, add the beef stock, minced garlic, bay leaf, thyme, salt, and black pepper.
Add the lid to the pot and bring it to a boil. Reduce the heat to a simmer and simmer for 20 minutes.
Step Three: Add the Bread and Cheese
Set out 6 oven-proof bowls. Put about 2 tablespoons of gruyere cheese in the bottom of the oven-proof soup bowls, then ladle soup evenly amongst the bowls. Place enough baguette slices to cover the top of the soup, then sprinkle more gruyere cheese on top. Some people will add the bread to the bottom of the bowl instead. You can do this if you’d like.
Place the soup crocks on a cookie sheet and turn the oven to a High Broil. Place in the oven under the broiler and broil until the cheese starts to bubble and toast.
Enjoy!
Expert Tips
- Stir the onions periodically when caramelizing, but do not stir too much. You want the onions to have a chance to caramelize with the browned bits on the bottom of the pot. Just make sure to not wait too long for your onions to start to burn instead of caramelize!
- You can also use comte cheese and add parmesan cheese to the top if you wish, though this is not traditional.
- This recipe calls for fresh herbs. If you decide to use dried you may want to use slightly less as dried herbs are a little bit concentrated.
- To deepen the flavor even further you could add a bit of sherry or red wine vinegar in with the broth.
FAQs
There are a few differences between onion soup and French onion soup. Onion soup isn’t very specific. It may use a few different types of onions and any type of beef or chicken stock.
French onion soup is specific about the type of onions and broth used. It also has the signature cheesy toast on top of each individual dish.
French onion soup is one soup that may require more than a spoon to enjoy.
The goal is to serve the soup while the gooey cheese is still freshly melted and hot, so that your guests can scoop fresh cheese, soft bread, and broth at the same time, but that might not always happen.
If you have French onion soup served to you and the cheese has had some time to settle, you may use a knife to push the melty cheese and bread to the edge of the dish to cut it and then push a bite-sized piece of cheesy bread onto your spoon with some broth.
It’s also a good idea, when you lift your spoon, to scoop away from your body. This allows any drips to drip back into the bowl, which is especially important with melted cheese.
If your soup tastes a bit bitter, you may have rushed your onions. You want to make sure the onions are cooked at a low temperature, nice and slow. Give it time!
Cooking the onions too fast may burn them or prevent them from picking up the sweetness of the sugar and butter.
You could also try using a different stock next time.
If you have never caramelized onions before you may be surprised by how long it takes. The cooking times for the caramelization process can take anywhere from 30 to 60 minutes.
Take your time and don’t try to rush things. Eventually, the onions will turn a deep golden brown and achieve that perfect depth of flavor, but it takes time!
Alcohol-Free Options
If you prefer to keep your French Onion Soup alcohol-free, you certainly can! In that case, I would recommend adding some balsamic vinegar or Worcestershire sauce to the pot of soup at the end to give it more depth of flavor. In the meantime, when the instructions call for using white wine to deglaze the pot, you can simply substitute with more beef broth.
How to Melt the Cheese if You Don’t Have Soup Crocks
This dish requires using oven-safe soup crocks in order to melt your cheese on top of the soup. If you do not have soup crocks, here are a few suggestions
- Place your bread on a cookie sheet and top with cheese, then broil this in the oven until the cheese is melted. Then scoop this up with a spatula and place on top of your soup bowl.
- Use a kitchen torch!

I can’t WAIT to try this. It sounds like heaven. Just being in an autumn kitchen with something wonderful streaming up the room and forcing you to take a step back to anticipate the holidays is one of my very favorite things.
