Instant Pot French Onion Soup is a restaurant-quality soup, easily and comfortingly made at home. It is loaded with caramelized onions, beef broth, and topped with Gruyere cheese, for the perfect finish!

We love making dishes in the Instant Pot because it’s convenient and usually done at a fraction of time. Like the Taco Soup and Baked Potato Soup, this French Onion Soup will quickly become your go-to soup.

Easy Instant Pot French Onion Soup

This Instant Pot French Onion Soup recipe is absolutely delicious. Unlike many other soups done in the pressure cooker, this one requires some extra time and attention in caramelizing the onions. After making this soup multiple times, we have come to the conclusion that for a perfect version of it, you will basically need to follow two important steps.

Step 1: Caramelizing the onions

This step takes some additional time to do in the Instant Pot. On average, it takes about 15-20 minutes to fully caramelize the onions. Hence, make sure to set time aside for the caramelizing part. Caramelizing is a process that occurs when sugar is added to the onions, and when they become brownish in color.

Step 2: Using high-quality beef broth

Since broth is the main ingredient here, make sure to use organic and high-quality broth. Your soup will only be as good as the stock you are using. The traditional French Onion Soup is made with beef broth, and this is what we have used here. So if you use boxed beef broth, taste it first!

How to make the perfect Instant Pot French Onion Soup:

Watch the recipe video tutorial attached. But the general steps are as follows:

  1. Add butter, sliced onions, and brown sugar to the pressure cooker. Saute for about 15-20 minutes or until onions are golden brown and caramelized.
  2. Next, add garlic, red wine, Worcestershire sauce, and the seasonings. Stir for 1-2 minutes.
  3. Then, add the beef broth. Seal pressure cooker and set to cook on high pressure for 20 minutes.
  4. After the time is done, release pressure naturally for 15 minutes, then release the remaining pressure by opening the vent.
  5. Before serving, top the serving bowl with a slice of baguette and plenty of Gruyere cheese. Place in the oven for a few minutes to broil. Broil until cheese is melted, and has a golden brown color.

Recipe Tips and Tricks:

  • For deeper flavor, you can even use Bone Beef Broth. Alternatively, you can substitute the beef broth with chicken broth.
  • For a vegetarian version, use vegetable stock.
  • Top the soup with your favorite cheeses. We have used Gruyere cheese, but a combination of provolone, Swiss or Parmesan will work just as well.

How to best serve Instant Pot French Onion Soup?

This delicious homemade soup is best to be served right away. Add some cheese on top, and use a fresh baguette for dipping. Also, it’s best to use cheeses that have some sharpness to them such as Gruyere or aged Beemster.

How to store Instant Pot French Onion Soup:

The soup can be stored in the fridge for up to 5 days. When ready to serve, heat the soup in a pot, and pour the soup into ceramic bowls. To create the cheesy bread topping, arrange baguette slices on top of each bowl, with some shredded or sliced cheese.

Then, put under the broiler for a few minutes until cheese is bubbly and golden brown.

One of my all-time favorites, love the sound of this IP version!



Looks heavenly! Nothing beats an Instant Pot soup this time of the year!


thank you!


Katerina @ diethood .com

Such a gorgeous soup!! I love that you made it in the Instant Pot!


So much quicker than the slow cooker!


Carrie R

Usually making homemade French onion soup is an all day thing! I love how quickly you can make this in the instant pot. :)


Allyson Zea

I've had instant pot French onion soup on my must make a list for a while, I cannot wait to try your recipe, it looks amazing!


Brandy O'Neill

Oh my goodness, this looks so good!


jessica | novice chef

the easiest way to my my all time favorite soup! i'm positively giddy over this!


:) its so good



Really tasty! I had to saute low to caramelize, it was burning too quick for me even though I was standing right there. I personally would add more onions for the second cook, the ratio of broth to onion “strings” was off for me. Delicious recipe, but all your recipes are delicious.



The soup is amazing the only thing we find is that the onions taste sweet in the soup. Is there anything we can do to make it more savory now that has been cooked.


Skip the brown sugar if you don't like the sweetness, and next time use regular yellow onions, not sweet. Also, you can add a bit more Worcestershire sauce.



What is the herb sprig in the photo?  I don’t see it listed in ingredients. 


thyme :)


D Fuller

EXCELLENT!! I did mix sweet with yellow onions and turned out so good. This is a forever recipe!



Any danger to cooking with wine in the IP? I see many warnings not to use alcohol even in a stovetop pressure cooker. Also, I assume that the alcohol does not cook off like it would in a traditional recipe, so  this recipe would not be particularly safe for children, correct?


The alcohol doesn't fully evaporate as it does on the stove or in the slow cooker. If you want to serve this to kids, all you have to do, after Pressure Cooking, open the IP, click on Saute and simmer the soup for 5-10 minutes, to make sure the alcohol evaporates.


I would also imagine that a cup of wine cooked for 2 minutes and then diluted into 64 ounces of broth would be pretty low in alcohol conent.

Delicious soup! My broiler isn’t working so I just cut the slices of Provolone cheese in small strips and place it on top of the soup. The cheese quickly melted into stretchy strings of yumminess and topped it off with a slice of French bread. By the way, I didn’t use salt; the broth and cheese have  plenty of sodium. I also replaced the wine by broth.


happy that you loved it!



Can you can this soup? Without the cheese until you reheat for serving. I somehow ended up with a bunch of onions and would love to make for winter


I don't see why not.


Susan Brous

We enjoyed this soup for dinner. Liked the fact that I didn’t have to smell the onions for quite as long. I needed to add salt and I rarely do that - should have tasted it more before I served it! I buttered pieces of a bagette and warmed it, then added slices of Gruyere and put it under the broiler. After I put the soup into the bowl, I added 3 pieces of bagette, then grated Gruyere cheese onto the bowl. (Afraid to put my china under the broiler). Thanks for the recipe.

Could you add beef to this soup? What do you think would change in the cook time?


you can brown some beef chunks and add it to the soup, I would increase the cooking time by 10 minutes.



I never leave comments on recipes but I had to with this one. I did the red wine (cooking wine) and substituted 2 cups bone broth and did only 6 cups of beef broth and it was AMAZING. Best french onion soup i've ever made. I would say that I'd prefer a swiss or parmesan cheese but wow.


Thanks for the comment, I am glad you liked it!)



I had a hard time getting the onions to brown. I got lots of water in the pot from the onions. Am I doing something wrong?


Make sure you Saute the onions on HIGH, and don't stir a lot. Also, add the onions when the oil is shimmering hot.


Darla T

First of all I love the soup! But like the previous comment I too had a hard time browning the onions I almost thought I used to many. My butter was melted but perhaps not hot enough. I did set the IP to high and maybe stirred too much. I see that you suggested not to stir too much. I think it would taste richer if I had browned the onions longer. But I will definitely try it again using your tips provided.


Hi Darla. Thanks for your feedback. I like browning it longer as well, it gives this soup a richer flavor. Try it the next time, and let us know how you liked it.



Fantastic- everything you want a French onion soup to be- salty and sweet. Very yummy



The soup was good but tasted too sweet instead of savory. Other recipes don't include brown sugar so definitely leave that out.


sara misener

I did a half portion for my little family but forgot to half the garlic (I added about 2 tables spoons) how do I fix this? Do it right next time? I’ll let yah know if it was overpowering but how could I counter balance it in the future.


Well, its a bit hard to mask the garlic, what you can do is add more of the other flavors, I hope it still tasted good.



Five onions were a lot, especially if you've got a smaller family. I cut everything in half and it was really good.


Glad that you liked it!


Kevin Hoover

Excellent Recipe, simple and delicious, thank you for sharing!


Kelly R

I’ve made this twice and it’s the best French Onion soup I’ve ever had


Hi Kelly! Glad you loved it! Thanks for the review!



Not going to lie, one of the best onion soups I’ve had. The only thing I changed was adding a spoonful of Better That Bouillon beef base dissolved in a cup of water for an extra kick.



This is wonderful! 💕 Thank you!
