Ingredients
  

  • 4 large onions thinly sliced
  • 2 tablespoons butter
  • 2 tablespoons olive oil
  • 1 teaspoon sugar
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 4 cloves garlic minced
  • 1/2 cup dry white wine optional
  • 8 cups beef broth
  • 2 bay leaves
  • 4-6 slices of French bread or baguette
  • 2 cups Gruyère or Swiss cheese grated
  • Fresh thyme sprigs for garnish (optional)

Instructions
 

  • In your Dutch oven, melt the butter and olive oil over medium-low heat. Add the thinly sliced onions, sugar, salt, and pepper. Stir well to coat the onions in the butter and oil mixture.
  • Cook the onions, stirring occasionally, for about 30-40 minutes, or until they become caramelized and turn a deep golden brown color.
  • Add the minced garlic to the caramelized onions and cook for an additional 1-2 minutes until fragrant.
  • If using, pour in the dry white wine to deglaze the pot, scraping up any browned bits from the bottom. Allow the wine to simmer for a few minutes to reduce slightly.
  • Add the beef broth and bay leaves to the pot. Bring the soup to a simmer, then reduce the heat to low, cover, and let it simmer for about 30 minutes to allow the flavors to meld. Remove and discard the bay leaves.
  • While the soup simmers, preheat your oven's broiler.
  • Place the slices of French bread on a baking sheet and toast them under the broiler until they turn golden brown. Keep a close eye on them to prevent burning. Remove the toasted bread from the oven.
  • To serve, ladle the hot soup into oven-safe soup bowls. Place a slice of toasted French bread on top of each bowl, covering the soup. Sprinkle a generous amount of grated Gruyère or Swiss cheese on top of the bread.
  • Place the soup bowls under the broiler until the cheese melts and turns bubbly and golden brown, about 2-3 minutes.
  • Carefully remove the soup bowls from the oven (they will be hot) and garnish with fresh thyme sprigs if desired.
  • Serve the French Onion Soup hot and enjoy!
