Vegetarian French Onion Soup


Vegetarian French Onion Soup

I love French onion soup, but it's almost always made with beef broth, and I'm a vegetarian. I have my own French onion soup recipe that is easy, vegetarian, and really yummy. Read on and learn how to make it yourself!

French Onion Soup Ingredients - Using vegetarian vegetable broth


This onion soup recipe is very simple, with no fancy ingredients and little prep work required. None of these measurements needs to be perfect. A little more or a little less of anything is no big deal with this soup. For best results, use a homemade vegetable broth.

  • 2 quarts vegetable broth, homemade or from the store
  • 2 pounds yellow onions, peeled and thinly sliced (about 6-7 medium size, no need to be too precise)
  • 2 cloves garlic, minced
  • 2 tablespoons vegetable or olive oil
  • 3 teaspoons sugar
  • Salt & pepper
  • Loaf of French bread, cut in one-inch slices
  • ½ pound Gruyere cheese, shredded or sliced

About the cheese - Use Gruyere for traditional French onion soup

I'm kidding. Mostly. Gruyere cheese is really stinky, but it's the traditional cheese for French onion soup, and I think it works best for this recipe. I don't even like Swiss cheese (and this is a particularly foul Swiss cheese), but I like it with the soup and encourage you to try it.

In the end, you can use whichever type of cheese you like, and I promise I won't judge. Unless you use Velveeta, because that's just wrong.

This soup is easy to make, and there is not much you can do to mess it up. Just watch the onions when you're browning them to be sure they don't burn.

  1. Heat the oil in the pot over medium heat.
  2. Add the onions to the hot pot and cook for about 10 minutes, stirring frequently. The onions should become soft but not yet browned.
  3. Add the sugar, salt, and pepper, and continue cooking for about 20 minutes. Stir frequently and lower the heat if necessary to avoid burning the onions. They should be golden brown and soft. Taste and adjust seasoning if necessary. (The onions should be fairly sweet at this point.)
  4. Add the garlic and broth and bring to a boil.
  5. Reduce heat and simmer for at least 15 minutes. You can keep the soup warm on the stove until ready to broil and serve, or allow it to cool and keep it in the refrigerator for 2-3 days.
  6. When ready to serve, heat the broiler and ladle the soup into individual oven-safe bowls.
  7. Top each bowl with a layer of bread, trimming slices if necessary to cover the entire surface.
  8. Cover the bread with the cheese. (Use sliced cheese and let it hang over the edges if you want the traditional messy French onion soup look and you don't mind scraping melted cheese off your bowls for hours later.)
  9. Heat under the broiler until the cheese is melted and beginning to brown.

Onion cutting tips - How to cut an onion without tears

Check out this video clip of the always-entertaining Alton Brown advising on cutting an onion without tears. (Goggles optional.)

Stockpots - Use a Large Pot for Making Soup

Prep Tools - A good knife and large cutting board makes it easier

Any knife and cutting board will work, but it's nice to have a large cutting surface and one really good knife to work with. My favorite all-purpose knife is a Santoku, which has dimples on the sides of the blade that help to release the food, so you don't have to push each slice off the blade.

Sounds good. We've been looking for a good veg french onion soup recipe. This sounds like it's worth a try... I love gruyere cheese!

I just love onion soup!

Onion soup is so yummy

Rose Jones on February 26, 2013:

I think I would prefer the beef broth, but I am willing to give yours a try. Pinned to my soup board and blessed. I am going to try Justin's suggestions.

anonymous on October 02, 2012:

I love "regular" French Onion soup but my girlfriend and roommate don't eat beef. I wanted to share the joy of this dish with them, so this recipe was a really great launchpad!

I recommend adding 1 cup of burgundy wine to the sauteed onions and letting that boil a bit until thick before adding the broth. Also, some spices: rosemary, sage and thyme to really make the flavors pop. Optional but awesome.

Thanks Freaknoodles!

Fantastic lens.

Barbara Walton from France on October 01, 2012:

What a chic looking lens - perfect for this classic French soup. Blessed!

@anonymous: A vegetarian doesn't eat meat. Cheese is dairy. There is a big difference between a Vegetarian and a Vegan.

anonymous on June 12, 2012:

@anonymous: cheese is an animal by product, not an animal product. beef broth, on the other hand, is made with the bones of the animal.

anonymous on May 31, 2012:

@anonymous: Vegans don't eat animal produced products such as cheese or eggs, however Vegetarians do. :)

anonymous on April 30, 2012:

you're a vegetarian and won't eat beef broth...but cheese is just fine? whatever.

waldenthreenet on April 17, 2012:

Valuable topic . Thanks. Gotta look for a "package" to make thing easier at "Trader Joes" or another grocery store in my neighborhood. Love French Cooking. COngrads on your Squidoo level 61. Conversations helps with new ideas. Thanks.

Great Lense, we make veggie french onion soup in our home.

anonymous on November 03, 2011:

If you eat Gruyere then I got news for you - you ain't vegetarian, as there are no versions of this cheese which use vegetarian rennet. It is thickened with lining of calf stomach, so you might as well have the traditional beef stock in your soup as you are eating one of the worst things there is. Sorry.

food monkey on October 24, 2011:

looks great! nice lens!

JodiFromFlorida on October 17, 2011:

Yum! Great lens.

anonymous on October 08, 2011:

Thank you! I have always loved French Onion Soup and have always been more of a vegetarian than anything else! Now I have many good things to experiment with! Thank you, again!

anonymous on September 15, 2011:

I have never tried it either. Great lens.

verkeerd on September 11, 2011:

Never tried the vegetarian version, I will very soon do it. Thanks!

anonymous on September 03, 2011:

@anonymous: Some vegetarians consume dairy, and some even consume eggs. It all depends on their choices. One can argue the egg consumption with the living versus not yet living debate.

anonymous on August 27, 2011:

@anonymous: Its very possible to call this vegetarian: Its easy to find vegitarian cheese. If you want it vegan just skip the cheese.

anonymous on August 27, 2011:

@GrinningFool: Easy: Dont put cheese on the bread and chose a bread without milk in it.

Jules Corriere from Jonesborough TN on August 25, 2011:

I just had to click on and see how to make a beef broth soup into a vegetarian soup! The recipe looks terrific! Thanks for sharing!

anonymous on June 14, 2011:

If a soup has cheese in it, how can it possibly be called vegetarian? Where does the cheese come from?

CherylsArt on June 10, 2011:

Sounds tasty. Blessed by your neighborhood Squid angel.

great lens i love soup and making it for my kids they love to eat it with crusty bread, my nickname at school was soup as i hate that much of it, and i could eat it everyday, how crazy is that ?, well done i love this lens ha ha

anonymous on March 03, 2011:

Please do not confuse Swiss cheese with Gruyere. And Gruyere does not stink. Try the true cave aged variety of Gruyere from Switzerland - you will never use another cheese where you need real cheese flavor.

greenkat lm on February 25, 2011:

Loved It! Thanks!

Krafick on February 22, 2011:

Onion soup is delicious. Thank you.

Diana Grant from United Kingdom on February 14, 2011:

It certainly looks good. I didn't know it needed sugar - I will try that, as I always think my onion soup is a missing a little je-ne-sai-quoit (I can't spell it either!).

@anonymous: You are aware that there are vegetable based, microbial, and genetically engineered rennets as well right? Or is your self-righteous attitude getting in the way of rational thought?

John Dyhouse from UK on October 19, 2010:

Did not realise that onion soup used beef stock, I make soups regularly and have never used anything other than a vegetable stock (low salt, of course)

gia combs-ramirez from Montana on October 16, 2010:

Yum! Didn't think vegetarian onion soup was possible!

piedromolinero on September 13, 2010:

@anonymous: nothing like a judgmental attitude to help educate or inspire someone to learn more being vegetarian!

WindyWintersHubs from Vancouver Island, BC on April 30, 2010:

Congratulations on your Purple Star! I usually make the beef broth version but always looking to try something new. Trying to eat less meat and more veggies. Thanks for our recipe. :)

anonymous on March 31, 2010:

strange, you claim to be vegetarian yet you eat cheese which contains rennet(stomach lining of a calf)!?! Hmm double standard. There are lots of veggie cheeses out there however... At least there are here in Holland. I too am a veggie and enjoyed your recipe. cheers

I love french onion soup. I always make it at home as usually the recipes in restaurants have a beef stock base and I am vegetarian!

MargoPArrowsmith on September 11, 2008:

Yum. Little better than a great bowl of French Onion Soup and the lens is just as delicious.

anonymous on August 20, 2008:

You can also use - McKay's beef broth - all veggie & no msg awesome tasing & they also carry chicken flavor for all your chicken receipts

freaknoodles1 (author) on August 19, 2008:

Hi Richard! You could definitely use vegetable stock cubes and water or cans or cartons of veggie broth from the soup aisle at the grocery store. If you have more time, you'll get the best flavor and the healthiest soup from homemade broth. I have instructions for homemade veggie broth at

anonymous on August 17, 2008:

What do you recommend the broth part to be made of: would vegetable stock cubes and water suffice?
