1 Pot French Onion Soup Vegan

So we got to work creating a 1-pot, plant-based version that doesn’t skimp on flavor. Spoiler alert? Major success! Let us show you how it’s done!

Origin of French Onion Soup

As the name suggests, French onion soup originated in France. Specifically, it’s believed that King Louis XV created it for a party when he was running low on ingredients (thank goodness for onions). Traditionally, this soup is made with a beef and onion base and topped with cheese and bread. The following is our plant-based take on the concept that doesn’t skimp on flavor or heartiness!

Vegan French Onion Soup

The flavorful base for this soup starts with caramelizing the onions in either oil, vegan butter, or water (if oil-free). This method of cooking onions low and slow maximizes their natural sweetness and creates tender texture. And adding a pinch of salt and pepper while cooking helps infuse them with even more flavor. Next, we added garlic and mushrooms to deepen the flavors and add an umami component. Optionally, arrowroot starch or cornstarch can be added at this time to help the soup become a thicker consistency (but it’s not necessary). For earthiness and some herbal notes, we added bay leaves and fresh thyme. Instead of the traditional beef broth, we used vegetable broth to keep this vegan. It’s equally as good (if not better), but it’s important to choose a rich and flavorful broth, such as our DIY vegetable broth or Pacific Foods for a store-bought option. Coconut aminos and miso paste are the final layers of flavor that add even more umami and take this soup to the next level. Swoon! The final (optional) step is to top the soup with croutons. Homemade croutons are incredibly easy to make (see recipe notes for instructions) and pair perfectly with this soup. We go for a nice sourdough for maximum flavor and texture. Want in on a secret? We like saving the best bites for last: A little onion soup and the last few croutons that remain crisp in parts but are slightly soft in others from soaking in the broth. SO satisfying! We hope you LOVE this vegan French onion soup! It’s:SavoryInfused with caramelized onionsComfortingQuick & easy& So delicious! It makes a satisfying entrée when topped with homemade croutons. And it’s also perfect as an appetizer or side, especially paired with other French-inspired recipes such as our Vegan Nicoise Salad (30 minutes!) or Vegan Zucchini Gratin.
