French onion soup

That is a big ask. French Onion Soup is more a thing in the US than France. When it does appear in France, it is a Winter dish, and by very definition, it is a soup with a beef base.

I would maybe start by searching for a vegetarian restaurant in the towns you plan on visiting, Paris would be more of a possibility than most, then look at menus.

I agree with Paul. French onion soup is not something I see on French menus. If you are wanting it to be truly vegetarian, go to a vegetarian restaurant. Paris is your best bet because of all the options. If you look at Julia Child's recipe, it includes a beef stock.

Okay, thanks! I didn’t realize it was more of a thing in the US. I will look for some vegetarian restaurants and see what they have.

My husband loved the onion soup in Obernai at l’Agneau d’Or. I have no idea if it was vegetarian.

French onion soup is all over brasserie menus.

I don't know anything about finding a vegetarian version though.

It's definitely a brasserie dish and traditionally the recipe calls for a beef stock base. I think it might be a bit difficult to find a brasserie that will make a vegetarian one, the French don't like to mess around with the classics.

I just returned from a week in Paris, onion soup gratin was on lots of menus I passed. Sorry, I have no idea of vegetarian menus.

It comes and goes into and out of fashion. Since COVID old fashion dishes are in favor.

hey hey mistimetotravel
can't help you with vegetarian french onion soup since it's beef based broth.

Thanks everyone for these suggestions. I will check the websites mentioned to look for restaurant ideas!
We are really excited to be going to and eating in Paris! : )

Le Potager du Marais does a vegan French onion soup. My niece who is a vegan thinks that it is quite good.

My daughter is vegetarian. She resigned herself to "loosening up a bit" in Europe. She did have French Onion Soup a few times. What she can't tolerate is bits of meat in anything, and I get that.

At home, I make vegetarian onion soup for her. I use more onions and let them caramelize with a bit of sugar for a long time being careful not to burn them. I then use a good vegetable stock, and do some nice slices of toasted baguette with Gruyere cheese and then it goes under a broiler.

The best onion soup I ever tasted was smack in the middle of summer in Lyon, France. I do agree that a vegetarian version may be a tough find.

Spent a week in Paris in February and ate French onion soup 3 times for lunch, was delicious each time.

Thanks again for the replies!
JHK, the restaurant you mentioned sounds great, Le Potager du Marias. We will give it a try and if they have french onion soup at the time that will be great and if not it sounds like a great place to eat anyway.
