Serves: 6
  • 6 Large Yellow Onions, peeled & thinly sliced
  • 4 tbsp. Butter
  • ½ cup Dry White Wine
  • 3 Garlic Cloves, minced
  • 3 tbsp All-Purpose Flour
  • 6 cups Beef Bone Broth
  • ½ tsp. Dried Thyme
  • 2 Bay Leaves
  • 1 tsp. Worcestershire
  • 1 tbsp. Sherry Vinegar
  • 1 tsp. Sugar, to taste
  • Salt + Pepper, to taste
  • 6 Slices Toasted Sourdough
  • 2 cups Shredded Cheese
  • Chopped Parsley, for garnish
  1. Thinly slice 6 large yellow onions and set aside. Melt a half stick of butter in a large Dutch oven and then add the sliced onions. Sauté over medium heat, stirring occasionally, until caramelized. Add a splash of white wine here and there to deglaze the bottom of the pot.
  2. Add the minced garlic and stir. Continue to sauté for a minute or so and then add the flour. Stir until well combined. Pour in the beef stock and then add the thyme, bay leaves, Worcestershire and sherry vinegar. Season with salt + pepper, taste, and add sugar if needed. Bring the pot to a simmer and continue to cook for 20 minutes.
  3. While the soup is simmering, toast the bread and shred the cheese.
  4. Ladle your desired amount of soup into an oven-safe bowl. Top each bowl with toasted bread and a big handful of cheese. Place them on a baking sheet and broil for 3 - 5 minutes, or until the cheese is melted, brown and bubbly.
  5. Serve immediately with a sprinkle of fresh parsley.
