Delicious Bowl of Classic French Onion Soup

Indulge in the rich and comforting flavors of classic French onion soup. This deeply flavorful soup features caramelized onions in a savory broth, topped with a crusty bread and melted Gruyère cheese.

Ingredients

Scale
  • 6 large yellow onions, thinly sliced
  • 4 tablespoons butter
  • 2 tablespoons olive oil
  • 1 teaspoon sugar
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 8 cups beef broth
  • 1 cup dry red wine (optional)
  • 1 bay leaf
  • 1 teaspoon dried thyme
  • 1 baguette, sliced into 1-inch thick rounds
  • 4 ounces Gruyère cheese, shredded

Instructions

  1. Melt butter and olive oil in a large pot or Dutch oven over medium heat. Add onions, sugar, salt, and pepper.
  2. Cook, stirring occasionally, for 30-45 minutes, or until onions are deeply caramelized and golden brown. Reduce heat if necessary to prevent burning.
  3. Add beef broth, red wine (if using), bay leaf, and thyme to the pot. Bring to a simmer and cook for 20 minutes.
  4. Preheat broiler. Place baguette slices on a baking sheet and broil for 1-2 minutes per side, or until lightly toasted.
  5. Ladle soup into oven-safe bowls. Top each bowl with 1-2 baguette slices and a generous amount of shredded Gruyère cheese.
  6. Broil for 2-3 minutes, or until cheese is melted and bubbly.
  7. Let cool slightly before serving.

Notes

For an extra layer of flavor, add a splash of Cognac or Sherry to the soup during the last few minutes of cooking. Serve hot and enjoy!
