Ingredients

The following ingredients have 4 Servings
  • 1 tablespoon unsalted butter
  • 3 large yellow onions, thinly sliced
  • 1 teaspoon kosher salt
  • 1 clove garlic, minced
  • 1/4 teaspoon sugar
  • 1/4 teaspoon dried thyme
  • 1 bay leaf
  • 4 cups (or 1 32 oz box) low sodium beef broth
  • 2 teaspoons worcestershire sauce
  • 1 cup bread cubes, french or ciabatta
  • 1 cup grated swiss cheese

Instruction

  • In a saucepan over medium heat, melt the butter.
  • Add the onions and salt and cook until onions start to turn golden brown, stirring occasionally, about 30 minutes.
  • Add the garlic, sugar, thyme and bay leaf and cook an additional 10 minutes.
  • Add the stock and worcestershire sauce and bring to a boil. Reduce heat to low and simmer until the onions are very tender, about 10 minutes.
  • Heat the oven to broil. Place the bread cubes on a baking sheet and broil for 3-5 minutes, or until crisp and golden.
  • Ladle the soup into oven-proof bowls. Top each bowl of soup with a handful of croutons and a handful of cheese.
  • Place under the broiler until the cheese is melted, about 2 minutes.
