Equipment

  • 1 large pot or Dutch oven
  • 1 wooden spoon
  • 1 ladle
  • 4 oven-safe bowls
  • 1 baking sheet
  • 1 knife
  • 1 cutting board

Ingredients
  

  • 4 large onions Thinly sliced (about 1.5 kg).
  • 4 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon salt
  • 1 teaspoon sugar
  • 4 cloves garlic Minced.
  • 8 cups beef broth (2 liters).
  • 1 cup dry white wine (240 ml).
  • 1 teaspoon dried thyme
  • 1 bay leaf
  • 8 slices French baguette
  • 1.5 cups shredded Gruyère cheese (about 150 g).
  • to taste freshly ground black pepper

Instructions
 

  • In a large pot or Dutch oven, melt the butter and olive oil over medium heat.
  • Add the sliced onions, salt, and sugar. Stir well to coat the onions.
  • Cook the onions, stirring occasionally, for about 30-35 minutes, until they are caramelized and golden brown.
  • Add the minced garlic and cook for another 1-2 minutes until fragrant.
  • Pour in the white wine and stir, allowing it to simmer for about 5 minutes to cook off some of the alcohol.
  • Add the beef broth, dried thyme, and bay leaf. Bring the mixture to a simmer and let it cook for 20 minutes to allow the flavors to meld. Season with freshly ground black pepper to taste.
  • While the soup simmers, preheat your oven to 350°F (175°C) and arrange the slices of baguette on a baking sheet. Toast them in the oven for about 10 minutes, turning halfway through.
  • Ladle the hot soup into oven-safe bowls, place one or two toasted baguette slices on top of each bowl, and generously sprinkle with Gruyère cheese.
  • Place the bowls on the baking sheet and broil in the oven for about 5 minutes, or until the cheese is bubbly and browned. Watch closely to prevent burning.
  • Carefully remove from the oven and let cool slightly before serving. Enjoy your delicious French Onion Soup!

Notes

You can substitute vegetable broth for beef broth for a vegetarian version.
If you prefer, add a splash of balsamic vinegar for extra depth of flavor before serving.
Feel free to garnish with fresh thyme or parsley for an added touch.
