Ingredients
  

Main Ingredients
  • 4 large onions
  • 2 tbsp butter
  • 6 cups beef broth
  • 0.5 cup dry white wine
  • 1 loaf baguette sliced
  • 1 cup Gruyere cheese shredded
  • salt and pepper to taste

Equipment

  • Large pot or Dutch oven
  • Oven-safe bowls

Method
 

Preparation
  1. Slice the onions thinly and set aside.
  2. In a large pot or Dutch oven, melt the butter over medium heat.
Cooking the Soup
  1. Add the sliced onions to the pot and cook slowly, stirring occasionally, until they are deeply caramelized and tender, about 30-40 minutes.
  2. Pour in the dry white wine and deglaze the pot, scraping up any browned bits from the bottom.
  3. Add the beef broth, bring to a simmer, then reduce heat and let it gently simmer for at least 20 minutes to allow the flavors to meld.
  4. Season the soup with salt and pepper to taste.
Serving
  1. Preheat your broiler.
  2. Ladle the hot soup into oven-safe bowls.
  3. Float a slice or two of baguette on top of each bowl of soup, then sprinkle generously with Gruyere cheese.
  4. Place the bowls under the broiler for 2-4 minutes, or until the cheese is bubbly and golden brown.

Notes

For an extra rich flavor, you can add a splash of brandy or sherry with the wine. Take your time caramelizing the onions, as this step is crucial for flavor development.
