French Onion Soup

French Onion Soup is a classic, hearty soup featuring caramelized onions simmered in rich beef broth, topped with toasted bread and melted cheese for a comforting and flavorful experience.

Ingredients

Scale
  • 4 large yellow onions, thinly sliced
  • 4 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 1 teaspoon sugar
  • 4 cloves garlic, minced
  • 8 cups beef broth
  • 1/2 cup dry white wine
  • 2 bay leaves
  • 1 teaspoon fresh thyme leaves or 1/2 teaspoon dried thyme
  • Salt and freshly ground black pepper, to taste
  • Baguette slices, toasted
  • 2 cups grated Gruyère cheese

Instructions

  1. In a large pot, melt butter with olive oil over medium heat.
  2. Add sliced onions and sugar; cook slowly, stirring frequently, until onions are golden brown and caramelized, about 30-40 minutes.
  3. Add minced garlic and cook for another 2 minutes until fragrant.
  4. Pour in white wine to deglaze the pot, scraping up any browned bits from the bottom.
  5. Add beef broth, bay leaves, and thyme; bring to a simmer.
  6. Reduce heat and let soup simmer gently for 20-25 minutes. Season with salt and pepper to taste.
  7. Preheat the broiler. Ladle soup into oven-safe bowls.
  8. Place toasted baguette slices on top of soup and generously cover with grated Gruyère cheese.
  9. Place bowls under the broiler until cheese is melted, bubbly, and golden brown, about 3-5 minutes.
  10. Remove carefully and serve hot.

Notes

For a vegetarian version, substitute vegetable broth for beef broth. Serve with a crisp green salad for a complete meal.
