French Onion Soup

French Onion Soup

French Onion Soup is a classic and comforting dish that combines caramelized onions with a rich beef broth and melted cheese. Here’s a step-by-step guide on how to prepare it:


For the soup:

  • 4 large yellow onions, thinly sliced
  • 3 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon sugar
  • 2 cloves garlic, minced
  • 8 cups beef broth (homemade or store-bought)
  • 1/2 cup dry white wine (optional)
  • 1 bay leaf
  • 2-3 sprigs of fresh thyme (or 1 teaspoon dried thyme)
  • Salt and pepper to taste

For the topping:

  • Baguette or French bread, sliced
  • 2 cups Gruyère or Swiss cheese, grated


  1. Caramelize the Onions:
    • Heat a large, heavy-bottomed pot or Dutch oven over medium-low heat.
    • Add the butter and olive oil, allowing the butter to melt.
    • Add the sliced onions and cook, stirring occasionally, until they become soft and golden brown. This process can take 30-45 minutes. Be patient; caramelizing the onions is essential for the soup’s flavor.
  2. Deglaze the Pot (optional):
    • If using wine, pour it into the pot and stir, scraping up any browned bits from the bottom of the pot.
  3. Add Sugar and Garlic:
    • Sprinkle sugar over the caramelized onions and add the minced garlic. Cook for an additional 1-2 minutes, stirring constantly.
  4. Add Broth and Seasonings:
    • Pour in the beef broth and add the bay leaf and thyme.
    • Season with salt and pepper to taste. Be cautious with the salt, as the cheese topping will also add some saltiness.
    • Bring the soup to a simmer, then reduce the heat to low and let it cook for about 20-30 minutes to allow the flavors to meld together.

  1. Prepare the Bread and Cheese Topping:
    • Preheat your oven’s broiler.
    • Slice the baguette into 1-inch thick rounds and toast them lightly.
    • Ladle the hot soup into oven-safe bowls.
    • Place a slice of toasted bread on top of each bowl of soup.
    • Sprinkle a generous amount of grated Gruyère or Swiss cheese over the bread.
  2. Broil and Serve:
    • Place the bowls under the broiler until the cheese is melted and bubbly and has a golden brown crust (usually 1-2 minutes, but keep a close eye on it to prevent burning).
    • Use oven mitts to carefully remove the bowls from the oven.
    • Let the soup cool for a minute or two before serving. Be cautious; the bowls will be hot!
  3. Enjoy!
    • Serve your French Onion Soup hot and enjoy the rich, savory flavors.

French Onion Soup is a delightful dish, perfect for a chilly day. The combination of sweet, caramelized onions, savory broth, and gooey cheese is sure to please your taste buds.
