Recipe For French Onion Soup l Vegetarian Version

french onion soup with garlic bread

French onion soup is really delicious and flavorful. It is prepared in beef stock but today, we will look at the vegetarian version of this dish. In this recipe we will use vegetable stock instead of beef stock and for deglazing we will use apple cider vinegar instead of dry white wine. It’s not easy to find Gruyere cheese in my region, so I have added Parmesan cheese. This is an easy homemade recipe and you won’t regret making it.

  1. I don't see where you add the 2 cups of veggie stock. I'm assuming some time after Steps 5 or 6. And you instruct to sauté onions -again- in step 4 after having caramelized them in Step 3. A little confusing.
