Ingredients

  • 2 tbsp vegan butter
  • 3 onions thinly sliced
  • ½ tsp organic cane sugar
  • 1 tsp dried thyme
  • 2 cloves garlic sliced
  • ¼ cup vegan red wine
  • 2 tbsp all-purpose flour
  • 4 cups vegetable stock
  • 2-3 small bay leaves
  • French baguette toasted, if desired
  • vegan mozzarella such as Miyoko's Creamery Fresh VeganMozz or Field Roast's Chao Vegan Slices
  • minced fresh chives for garnish, if desired

Instructions

  • Melt the butter in a large soup pot over medium heat. Add the onions and sugar and stir well. Cook, stirring occasionally, until soft and caramel-colored, about 30-45 minutes.
  • Add the thyme and garlic to the caramelized onions, stir and then cook just until fragrant, about 30 seconds.
  • Pour in the red wine and using a spoon or spatula, scrape the bottom of the pot to bring up any browned bits. Stir in the flour and cook for 1 minute.
  • Add the vegetable stock and bay leaves, stir well, and let the soup simmer until the flavors meld, about 15 minutes.
  • Preheat the broiler. Ladle your vegan French onion soup into oven-proof ramekins or bowls, filling each only halfway. Add 1 slice of baguette bread to each dish and ladle the remaining onion soup over the bread, then top with a layer of vegan cheese. Broil until the cheese is melted.
  • Serve your soup piping hot with minced fresh chives for garnish, if you like.

Notes

Ingredients

  • Sweet vidalia onions are my top choice for this soup, or yellow onions work well too. 
  • Choosing a vegan cheese that melts readily is key for this recipe! I like using either shredded or sliced mozzarella style vegan cheeses. Brands like Miyoko’s Creamery or Field Roast’s Chao have good options. 

Tips

  • Patience is a virtue when it comes to caramelizing onions. Keep the heat low to medium, stir often, and add a splash of water if you see too much brown accumulation on the bottom of the pot. 

Storage

  • Refrigerate leftovers in an airtight container for up to 3 days. 
  • Freeze your French onion soup for up to 3 months–as long as it does not already have sliced baguette and cheese in it.
  • Reheat leftovers in a pot over low-medium heat, portion into bowls, top with sliced baguette and cheese, then broil until melted.
