French Onion Soup is a classic, comforting dish made with deeply caramelized onions, a savory broth, and a rich, cheesy topping. Perfect for cozy nights or special occasions, this soup is both satisfying and impressive.

Ingredients

  1. For the soup:
  2. 4 large yellow onions, thinly sliced
  3. 2 tablespoons unsalted butter
  4. 1 tablespoon olive oil
  5. 2 cloves garlic, minced
  6. 4 cups beef broth (low-sodium if preferred)
  7. 1 cup dry white wine (or more broth for a non-alcoholic version)
  8. 1 teaspoon dried thyme (or 2 teaspoons fresh thyme)
  9. 1 bay leaf
  10. Salt and pepper, to taste
  11. 1 tablespoon balsamic vinegar (optional)
  12. For the topping:
  13. 4 slices French baguette or crusty bread
  14. 1 1/2 cups grated Gruyère cheese (or Swiss cheese)

Instructions

In a large pot or Dutch oven, heat butter and olive oil over medium heat. Add sliced onions and cook for 35-40 minutes, stirring occasionally, until golden brown.

  1. Add minced garlic and cook for another 1-2 minutes. Add wine (if using) and scrape the pot to loosen browned bits. Let the wine reduce for 2-3 minutes.
  2. Add beef broth, thyme, bay leaf, salt, and pepper. Bring to a simmer and cook for 20-30 minutes, adjusting seasoning. Add balsamic vinegar for extra flavor if desired.
  3. While the soup simmers, preheat the oven to 350°F (175°C). Toast bread slices in the oven for 8-10 minutes, until golden and crispy.
  4. Ladle soup into oven-safe bowls, place toasted bread on top, and sprinkle with grated Gruyère cheese.
  5. Preheat the broiler, then place the bowls under the broiler for 2-3 minutes until the cheese is melted and bubbly. Keep an eye on it to avoid burning.
  6. Carefully remove the bowls from the oven and serve immediately, garnished with fresh thyme if desired.

Notes

  1. For a vegetarian version, use vegetable broth instead of beef broth.
  2. Try adding rosemary or sage for a different herbal note.
  3. If Gruyère is unavailable, substitute with Swiss cheese or mozzarella.
  4. Use any sturdy bread for the topping, such as sourdough or whole grain.
