Ingredients
  

  • 4 large yellow onions thinly sliced
  • 4 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 1 teaspoon sugar
  • 2 cloves garlic minced
  • 8 cups beef broth or vegetable broth
  • ½ cup dry white wine optional
  • 1 teaspoon fresh thyme leaves or ½ teaspoon dried thyme
  • Salt and pepper to taste
  • 1 baguette sliced and toasted
  • cups grated Gruyère or Swiss cheese

Instructions
 

Caramelize the Onions:

  • In a large pot, heat butter and olive oil over medium heat. Add onions and sugar. Cook slowly, stirring frequently, until onions are deep golden brown and caramelized, about 35–40 minutes.

Add Garlic & Deglaze:

  • Add garlic and cook for 1 minute. Pour in white wine (if using) and scrape up browned bits from the bottom.

Add Broth & Simmer:

  • Add beef broth and thyme. Season with salt and pepper. Simmer uncovered for 15 minutes.

Prepare Bread & Cheese:

  • Preheat the oven broiler. Place toasted baguette slices on a baking sheet, top with grated cheese. Broil until cheese melts and bubbles.

Serve:

  • Ladle soup into oven-safe bowls, top each with a cheese toast slice. Serve immediately.
