Vegan French Onion Soup Recipe - The Herbeevore (1)

I have made a lot of recipes on this blog, and I don’t think anything has earned the title of EPIC yet… until this amazing vegan French Onion Soup. My husband and I LOVE French food – we took a trip to Lyon a few years back and it was definitely a food-based vacation. The food in Lyon really just ruined any other dining experience for me, nothing has compared to the little bistros, 3 course meals, and bottles of French wine.

Luckily, we have found some great French restaurants in our area which are perfect when we are feeling like indulging. Pot Au Feu in Providence, RI is outstanding (definitely our favorite ‘splurge’ restaurant… which also has a vegan menu!), and La Voile in Boston is also a favorite.

Make French Onion Soup Vegan for a Plant-Based Version

This vegan French onion soup is a simple way to get extra veggies in your diet. I’m all about making recipes plant-based when I can. Vegan cooking does NOT have to be bland, boring, or flavorless… It’s quite the opposite when done right. By building meals around vegan pantry staples and swapping in a few plant-based ingredients you can make better meals for you and your family.

What’s In Vegan French Onion Soup?

See the recipe card below for full ingredient amounts and recipe instructions!

  • Onions, Thyme
  • Extra Virgin Olive Oil
  • Low Sodium Vegetable Stock – I like to use this low sodium vegetable stock for my recipes because it has great flavor… without all the salt. I always use low sodium or no-salt-added broth or stock to start, and then I can add salt or other spices later if needed.
  • Vegan/Gluten Free Bread – use a gluten free bread if you can’t eat wheat. I like to make my own bread, and they have some great artisan bread gluten free mixes out there too!
  • Parmesan Substitute for a vegan version! – gives that extra bit of flavor and richness to this dish. A vegan version adds a little extra into the soup (and for garnish) makes this dish delicious.

Onions absolutely shine in this recipe, and with the few other simple ingredients transform into an amazing, flavorful, and rich soup.

It’s a little time consuming cook down the onions, but let me tell you it is WORTH IT. This is a great recipe for when you want something fancy and have a few extra hours to spare in the kitchen (doesn’t happen too often, but I’ll take them when I can get them)!

Rave reviews for this recipe, I cannot wait to make this again! It was just as good as the restaurant and almost as good as being in actual France 🙂
