- ¼ cup unsalted butter (1 stick)
- 6 yellow onions thinly sliced
- 6 garlic cloves minced
- 1 teaspoon dried thyme or 3 sprigs of fresh thyme
- 6 cups beef broth
- 1 tablespoons balsamic vinegar
- 1 teaspoon Dijon mustard
- 4 slices baguette or 12 slices if using a skinny baguette
- 1 cup grated Gruyere cheese or Emmenthal cheese
Melt the butter in a large saucepan over medium heat. Add the onions, garlic, and thyme and cook for about 45 minutes, stirring occasionally, until the onion are very soft and brown.
Add the wine and balsamic vinegar and stir until syrupy, about 3 minutes. Add the beef broth and Dijon mustard and simmer about 20 minutes.
Place the baguette slices on a cookie sheet and toast in a 350 degree oven for about 5 minutes.
Preheat the broiler. Ladle the soup into ovenproof bowls and top each with 3 baguette slices and ¼ cup cheese. Broil until the cheese is bubbling and slightly brown. Serve.
