Description

This classic French Onion Soup recipe features deeply caramelized onions simmered in rich beef broth with red wine and herbs, topped with toasted baguette slices and a generous layer of melted Gruyere and Parmesan cheese.

Ingredients

Scale
  • 2 tablespoons olive oil
  • 2 tablespoons unsalted butter
  • 1½ pounds yellow onions, peeled, halved, and thinly sliced
  • ½ teaspoon sugar
  • 1 teaspoon salt
  • 3 tablespoons all-purpose flour
  • 1 tablespoon unsalted butter
  • 6 cups beef broth, low sodium or no sodium added
  • 1 cup dry red wine (Pinot Noir, Côtes du Rhône, or Merlot)
  • 2 bay leaves
  • 3 sprigs thyme
  • 3 tablespoons cognac
  • 8 slices French baguette
  • 2 cups Gruyere cheese, shredded
  • ½ cup Parmesan cheese, grated

Instructions

  1. In a large heavy pot such as a Dutch oven, heat olive oil and 2 tablespoons of butter over medium heat until the butter melts. Add the sliced onions and stir to coat them evenly in the oil. Cover the pot with a lid and cook for 20 minutes, stirring every few minutes. The onions should turn transparent after this initial cooking.
  2. Remove the lid, then stir in the sugar and salt. Continue cooking uncovered for another 40 minutes, stirring occasionally. The onions should turn a deep golden brown and develop a sweet, rich flavor.
  3. Add the flour and remaining 1 tablespoon butter to the pot. Stir well and cook for 2 to 3 minutes to eliminate the raw flour taste and slightly thicken the mixture.
  4. Pour 1 cup of beef broth into the pot and stir thoroughly, scraping the bottom to release any browned bits. Cook for about 1 minute until the liquid begins to evaporate.
  5. Add the remaining broth, red wine, bay leaves, and thyme sprigs to the pot. Stir to combine.
  6. Bring the soup to a boil, then reduce heat to a simmer. Let it cook uncovered for 30 minutes to meld the flavors. Remove and discard the bay leaves and thyme sprigs afterward.
  7. Taste the soup and adjust seasoning with salt and pepper as needed. Stir in the cognac to finish the base.
  8. Preheat your broiler. Lightly brush the baguette slices with olive oil and toast them under the broiler for 30 seconds to 1 minute per side until golden. Ladle soup into ovenproof bowls, sprinkle about 1 cup of Gruyere cheese over the top, then place the toasted bread slices onto the cheese. Top the bread with remaining Gruyere and Parmesan cheese.
  9. Preheat your oven to 350°F (177°C). Transfer the bowls to the oven and bake for 20 to 25 minutes, or until the cheese melts and starts to brown lightly. Serve hot and enjoy.
