This Vegan Onion Soup recipe produces a delicious, healthy, comforting, soup with a rich broth. Yum! Dairy-free and low-fat, we  know you’ll love it!


Units Scale

45 medium onions, thinly sliced

1 Tbs vegan butter or oil (optional)

pinch of salt

2 tsp mustard seeds

1/2 tsp celery seeds

67 grinds of black pepper

2 cups vegetable broth

1/4 cup tamari (I use low sodium)

1/4 cup white wine

Toasted french bread slices, or croutons, and vegan cheese (optional)


1. Melt butter or heat oil or water in a soup pot on medium heat with enough bottom surface area to be able to move the onions around in a fairly thin layer.

2. Add the onions and stir to coat.

3. Sprinkle with pinch of salt.

4. Stir the onions frequently and gently, maintaining a medium heat.

5. Add the mustard and celery seeds and black pepper and continue to stir.

6. And stir.

7. When the onions are a golden to caramel color, add the broth, tamari and wine and bring to a gentle boil.

8. Adjust salt and pepper to taste with care, as tamari can be high in sodium.

9. Remove from heat and serve into bowls, placing toasted bread and a generous sprinkle of cheese on top, if desired.


Yield: 2 main course or 4 appetizer servings.

There are lots of vegan cheeses available, and more appear all the time. Follow Your Heart* brand has been reliable and generally easy to find. We love their shreds, and their Parmesan Style works particularly well with this recipe.
