Description

French Onion Soup is a classic French dish known for its rich, caramelized onion flavor and comforting warmth. This recipe combines sweet onions, savory beef broth, and a topping of toasted bread with melted cheese.


Ingredients

Scale
  • 6 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 8 cups thinly sliced yellow onions (about 3 pounds)
  • 1 teaspoon sugar
  • 2 cloves garlic, minced
  • 1/2 cup dry white wine
  • 8 cups beef broth
  • 2 bay leaves
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
  • Salt and freshly ground black pepper, to taste
  • 1 baguette, sliced into 1/2-inch thick rounds
  • 2 cups grated Gruyรจre cheese

Instructions

  1. Caramelize the Onions:
    • In a large pot or Dutch oven, melt the butter with the olive oil over medium heat.
    • Add the sliced onions and stir to coat them with the butter and oil.
    • Cook the onions, stirring occasionally, until they become soft and golden brown, about 45 minutes.
    • Sprinkle the sugar over the onions to enhance caramelization and continue cooking for an additional 5 minutes.
  2. Add Garlic and Wine:
    • Stir in the minced garlic and cook for about 1 minute until fragrant.
    • Pour in the white wine to deglaze the pot, scraping up any browned bits from the bottom.
    • Allow the wine to simmer until it reduces by half, approximately 5 minutes.
  3. Add Broth and Herbs:
    • Add the beef broth, bay leaves, and thyme to the pot.
    • Bring the soup to a boil, then reduce the heat and let it simmer uncovered for 30 minutes.
    • Season with salt and freshly ground black pepper to taste.
  4. Prepare the Bread:
    • While the soup is simmering, preheat your ovenโ€™s broiler.
    • Arrange the baguette slices on a baking sheet and toast them under the broiler until golden brown on both sides.
    • Remove from the oven and set aside.
  5. Assemble and Serve:
    • Remove the bay leaves from the soup.
    • Ladle the hot soup into oven-safe bowls or crocks.
    • Place one or two toasted baguette slices on top of the soup in each bowl.
    • Sprinkle a generous amount of grated Gruyรจre cheese over the bread and soup.
    • Place the bowls on a baking sheet and transfer them to the oven under the broiler.
    • Broil until the cheese melts and becomes bubbly and lightly browned, 3 to 5 minutes.
    • Carefully remove from the oven and serve hot.

Notes

  • For a deeper flavor, consider using a combination of beef and chicken broth.
  • If you prefer a milder cheese, Swiss or Emmental can be used in place of Gruyรจre.
  • To save time, the onions can be caramelized in advance and stored in the refrigerator for up to 3 days.
