Caramelized onions simmered with herbs and red wine go into this savory vegan French onion soup.
Begin by prepping onion, celery and garlic.
Heat a large pot over medium heat, add olive oil and veggies. Stir well and allow to cook until they become soft and caramelized; about 1 hour. Stir occasionally.
Stir in wine if using, thyme, bay leaves and chili pepper flakes while soup is simmering. If using red wine, lower heat and continue to cook until wine is reduced by half, about 3 minutes. Otherwise, on low heat add broth and bring heat to medium and allow to simmer to an additional 20 minutes. Stir frequently.
Taste and season with salt and pepper. Serve immediately with your favourite vegan cheese, crusty bread or green salad.
