I’ve always loved French Onion Soup. It was one of my very favorite foods as a kid.
And it was one of the first things that I really missed when moving to a more plant-based diet.
Traditional French Onion Soup is made with beef broth and topped with cheese.
So I set out to make this Vegan French Onion Soup. My version uses a vegetable stock, infused with savory flavor from balsamic vinegar.
It gives that rich, deep flavor that French Onion soup is known for, but it’s completely plant-based.
And of course, we can’t miss out on the ooey, gooey, melted cheese topping!
I used a slice of fresh baguette and topped it off with dairy-free cheese. Be sure to choose a brand that melts well for the best result.
And the best part about this easy vegan soup – it cooks up in a single pot! So it’s easy to cook, and easy to clean up too. What’s not to love about that?

Tips for Perfect Vegan French Onion Soup
- Slicing all those onions can wreak havoc on your eyes! A little trick? Chew a stick of peppermint gum while you slice. I swear it works.
- Be sure to use a vegan cheese that melts well for the best cheesy topping. I really like Daiya, Follow Your Heart, and So Delicious brands for good melting!
- Make some extra cheesy toasts on a baking sheet to serve alongside the soup. I’ve found that I always want extra for more dipping in my soup.

Vegan French Onion Soup
Ingredients
- 2 tbsp olive oil

Instructions
- Preheat the oven to 350°F (175°C, or gas mark 4).
- Heat the olive oil in a large stockpot over medium-low heat. Add the onions and cook slowly for 15 to 20 minutes, stirring often, until they are lightly caramelized. Add the garlic, bay leaves and thyme. Cook for 1 minute. Add the white wine and cook for 5 to 7 minutes, until slightly reduced. Add the vegetable broth and bring to a boil. Reduce the heat and simmer for 20 minutes.
