Description

French Onion Soup with Cheesy Bread is a rich and savory soup made with caramelized onions, beef broth, and a touch of wine, topped with a hearty slice of toasted bread and melted cheese. A classic comfort food perfect for chilly days.


Ingredients

  • 4 large onions, thinly sliced
  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 cup dry white wine (optional)
  • 4 cups beef broth
  • 1 bay leaf
  • 1 tablespoon balsamic vinegar (optional)
  • 4 slices of crusty French bread
  • 1 1/2 cups shredded Gruyère cheese (or Swiss cheese)
  • Fresh parsley, chopped, for garnish

Instructions

  1. In a large pot, heat butter and olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, for 25–30 minutes until onions are caramelized and browned.
  2. Add garlic, thyme, salt, and pepper, and cook for another 2 minutes until fragrant.
  3. Pour in the white wine (if using) and scrape up any brown bits from the bottom of the pot. Let it simmer for 3–4 minutes to reduce.
  4. Add beef broth and bay leaf, bring to a boil, then reduce heat and let simmer for 20–25 minutes. If using, stir in balsamic vinegar for added depth of flavor.
  5. While the soup simmers, toast the French bread slices in the oven or on a skillet until golden brown.
  6. Preheat the broiler in your oven. Ladle the soup into oven-safe bowls, place a slice of toasted bread on top of each bowl, and sprinkle generously with shredded Gruyère cheese.
  7. Place the bowls under the broiler for 2–3 minutes, or until the cheese is melted and bubbly, being careful not to burn the bread.
  8. Garnish with fresh parsley and serve hot.

Notes

  • For a more traditional flavor, use a mixture of beef and chicken broth.
  • Gruyère cheese is ideal for melting, but Swiss or mozzarella can be used as alternatives.
  • If you don’t have oven-safe bowls, you can toast the cheesy bread separately and place it on the soup just before serving.
