Description

A classic French onion soup featuring deeply caramelized onions simmered in rich broth, topped with toasted baguette slices and melted Gruyère cheese, delivering a warm and comforting culinary experience perfect for any season.

Ingredients

Soup Base

  • 4 large onions, thinly sliced
  • 3 tbsp butter
  • 1 tbsp olive oil
  • 1 tsp sugar
  • 4 cups beef broth
  • 1/2 cup dry white wine (optional)
  • Salt and pepper to taste

Topping

  • 1 baguette, sliced
  • 1 cup Gruyère cheese, shredded

Instructions

  1. Caramelize Onions: Melt the butter with olive oil in a large pot over low heat. Add the thinly sliced onions and cook slowly, stirring often, until the onions are deeply caramelized, which brings out their natural sweetness and rich flavor.
  2. Add Sugar and Continue Cooking: Sprinkle the sugar over the onions and continue cooking until they turn a golden brown color, enhancing the caramelization process and deepening the soup’s flavor.
  3. Deglaze and Add Broth: Pour in the dry white wine if using, scraping the pot’s bottom to release any browned bits. Then add the beef broth, stirring to combine all ingredients.
  4. Simmer the Soup: Allow the soup to simmer gently for about 20 minutes to meld the flavors together. Season with salt and pepper to taste.
  5. Prepare the Toppings: While the soup simmers, toast the baguette slices until they are crisp. Then, generously top each slice with shredded Gruyère cheese.
  6. Assemble and Broil: Ladle the hot soup into oven-safe bowls, place a cheese-topped baguette slice on top of each, and place the bowls under a broiler until the cheese melts and becomes bubbly and golden, creating a delicious crust.

Notes

  • Patience is key for caramelizing onions properly; slow cooking ensures deep flavor without burning.
  • Gruyère cheese provides authentic taste and excellent melting quality, but Swiss cheese may be used as a substitute.
  • This soup can be prepared in advance and reheated gently before serving to save time.
