How To Make Vegan French Onion Soup

Making French onion soup is easier than you'd initially think! In a saucepot, melt the butter over medium heat. Toss in onions and cane sugar, stirring occasionally for about 45 minutes. Let the onions cook until they are caramelized to perfection. Slowly stir in dried thyme with the caramelized onions and sauté for 30 seconds before deglazing the pot with red wine. Sprinkle in the flour and cook for approximately a minute. Carefully pour in the veggie stock and allow it to simmer, still on medium heat, for 15 minutes. After preheating the broiler, fill individual ramakins with warm soup about halfway. Place a piece of baguette bread in the middle and pour more soup over the bread until completely covered. Top off your creation with vegan cheese before placing each ramekin under the broiler until the cheese is melted and has turned deep golden brown. Serve this delightful vegan French onion soup as desired, and enjoy!
