About French Onion Soup

French Onion Soup is a classic and comforting dish that originates from France. It is a savory soup made from caramelized onions, beef broth, and typically topped with melted cheese and toasted bread. It is known for its rich and deep flavors, making it a favorite among soup enthusiasts.

Traditionally, French Onion Soup was a peasant dish as onions were widely available and affordable. It dates back to the 18th century in France and has since gained popularity worldwide. The key to its delicious taste lies in the slow cooking process of the onions, which brings out their natural sweetness and deepens their flavors. The soup is often garnished with a thick slice of toasted bread, like baguette, topped with melted Gruyere or Swiss cheese, which creates a luscious, gooey texture and adds a wonderful cheesy taste to the dish.


Cooking Steps for French Onion Soup:

Step 1:

  • Melt butter in a large pot over medium heat.
  • Add thinly sliced onions and cook until caramelized, stirring occasionally.

Step 2:

  • Sprinkle flour over the caramelized onions and stir well to coat.
  • Cook for a few minutes to cook off the raw flour taste.

Step 3:

  • Pour in beef broth and stir to combine.
  • Add fresh thyme, bay leaves, and season with salt and pepper.
  • Simmer the soup for about 30-40 minutes to allow flavors to meld together.

Step 4:

  • While the soup is simmering, slice a baguette into thick rounds.
  • Toast the bread slices until crispy.

Step 5:

  • Once the soup is ready, discard the bay leaves and thyme sprigs.
  • Ladle the soup into oven-safe bowls.
  • Place a slice or two of toasted bread on top of each bowl.
  • Sprinkle generous amounts of grated Gruyere cheese over the bread.

Step 6:

  • Broil the soup bowls in the oven until the cheese is melted and bubbly.

Step 7:

  • Remove from the oven and let the soup cool for a few minutes before serving.
