A Recipe of a Slow Cooker French Onion Soup

Needed Ingredients:

  • 3 lbs yellow onions, julienned
  • 2 tablespoons of unsalted organic, grass-fed butter
  • 8 cups of beef broth or vegan broth
  • 2 tablespoons of an extra virgin olive oil
  • 2 sprigs of fresh thyme
  • A quarter cup of balsamic vinegar
  • 2 ½ teaspoons of kosher salt
  • Freshly ground black pepper
  • 1 ⅓ to 2 cups grated Gruyere cheese or nutritional yeast ( the right measure is ⅓ cup per bowl)
  • 4 to 6 whole grain or gluten-free baguette slices, toasted (you should use 1 slice per bowl)


For the preparation of this delicious onion soup you will need to use a slow cooker. Set it on low, and cook the onions, olive oil, butter, black pepper, and salt for 10 to 12 hours. It is best to cook during the night, and in the morning add the broth (either beef or vegetable), thyme, and balsamic vinegar. Cover it and continue to cook for 6 to 8 hours more.

When the cooking part has finished, it starts the baking part. For that purpose, you need to preheat the oven at 350 degrees Fahrenheit, and with a spoon place the soup into oven-safe bowls.

Place the bowls on a baking sheet, cover each bowl with a baguette slice and on top put either the cheese or nutritional yeast, and like that bake for 30 minutes.

When the cheese turns brown, remove the bowls from the oven, and after 5 minutes serve them to your guests.
