 Classic French Onion Soup Recipe

 Ingredients:

  • 4 large yellow onions, thinly sliced 
  • 3 tablespoons unsalted butter 
  • 1 tablespoon olive oil 
  • 2 cloves garlic, minced 
  • 1 teaspoon sugar (to help caramelize the onions) 
  • 1/4 cup dry white wine 
  • 6 cups high-quality beef broth (preferably homemade or organic) 
  • 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme) 
  • 1 bay leaf 
  • Salt and pepper to taste 
  • 1 baguette, sliced into 1-inch rounds 
  • 2 cups grated Gruyère cheese 

‍ Instructions:

  1. Caramelize the Onions: In a large pot or Dutch oven, melt the butter and olive oil over medium heat. Add the thinly sliced onions and cook, stirring occasionally, until they become soft and translucent (about 15 minutes). Then, stir in the sugar and garlic. Continue cooking on low heat for 40-50 minutes, stirring occasionally, until the onions are golden brown and caramelized. ✨
  2. Deglaze with Wine: Once the onions are beautifully caramelized, increase the heat to medium-high and add the white wine. Stir well, scraping up any browned bits from the bottom of the pot. Let the wine simmer for 5-7 minutes, reducing slightly. 
  3. Add the Broth: Pour in the beef broth, thyme, and bay leaf. Bring the soup to a simmer, then reduce the heat to low and let it cook for 30 minutes, allowing the flavors to meld together. Season with salt and pepper to taste. 
  4. Prepare the Baguette: While the soup simmers, preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet and toast them in the oven until crisp and golden brown, about 10 minutes. 
  5. Assemble and Broil: Ladle the soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl and generously sprinkle with grated Gruyère cheese. Place the bowls under the broiler for 2-3 minutes, or until the cheese is melted, bubbly, and golden brown. 
  6. Serve and Enjoy: Carefully remove the bowls from the oven, garnish with a sprig of thyme if desired, and serve your delicious Classic French Onion Soup piping hot. Enjoy the rich flavors with each spoonful! ✨

 Frequently Asked Questions

1. Can I use chicken broth instead of beef broth?
Yes, although beef broth is traditional for its deep flavor, chicken broth can be used if you prefer a lighter taste. However, the richness of beef broth really complements the caramelized onions.

2. What can I substitute for Gruyère cheese?
If Gruyère isn’t available, you can substitute it with Swiss cheese, Emmental, or even mozzarella for a gooey, melty topping. However, Gruyère gives the soup its authentic nutty flavor.

3. How do I store leftovers?
Store any leftover French Onion Soup in an airtight container in the refrigerator for up to 3 days. Reheat on the stovetop and prepare fresh toasted baguettes when serving.

4. Can I make this soup ahead of time?
Absolutely! In fact, the flavors deepen as the soup sits. You can make the soup a day ahead, then toast the baguettes and broil the cheese just before serving.

5. Is this soup freezer-friendly?
Yes! You can freeze the soup (without the baguette and cheese) in an airtight container for up to 3 months. When ready to eat, defrost, reheat, and add the freshly toasted baguette with melted cheese.
