The Iconic French Onion Soup

Bonjour, dear readers! Today, I am excited to take you on a little culinary journey right to the heart of French tradition with one of our most beloved comfort dishes: the Soupe Ă  l’oignon, or French onion soup. It’s a joy to share this classic recipe with you. So, grab your apron and get ready to warm your soul with this exquisite soup!

A Love Affair with French Onion Soup

First, a tale of tradition: The French onion soup traces its history back to ancient times but became particularly popular in France in the 18th century. It’s said that King Louis XV accidentally invented it during a hunting trip when he combined onions, butter, and champagne out of sheer desperation when nothing else was available. Whether this is fact or myth, one thing is clear—this soup has a cozy legacy in French cafĂ©s and kitchens.

Ingredients: A Dance of Simple Elegance

To prepare approximately four servings of this delightful soup, you’ll need the following ingredients:

  • đź§… 4 large yellow onions, thinly sliced
  • 2 tablespoons of unsalted butter
  • 1 tablespoon of olive oil
  • 4 cups of beef stock or broth
  • 1 cup of dry white wine (or more stock for a non-alcoholic version)
  • 2 tablespoons of all-purpose flour
  • Salt and freshly ground black pepper, to taste
  • 🥖1 baguette, sliced into rounds
  • 2 cups of grated Gruyère cheese (or Emmental, as an alternative)
  • 1 teaspoon of sugar (optional, to enhance the natural sweetness of the onions)
  • A splash of Cognac or Brandy (optional, for extra depth)

Step-by-Step Preparation: Unfolding the Flavor

  1. Sweating the Onions: In a large heavy-bottomed pot, melt the butter with olive oil over medium heat. Add the sliced onions and a pinch of salt, stirring often until they turn soft and translucent.
  2. Caramelizing Perfection: Lower the heat slightly and continue cooking the onions—this is where patience is your best ally. Stir frequently until the onions are richly caramelized and golden brown (this could take up to 40 minutes). Sprinkle in the sugar halfway, if desired, to speed up caramelization.
  3. Deglazing the Symphony: Sprinkle the flour over the onions and cook for another minute, stirring constantly. Gradually add the wine to deglaze the pot, scraping up all the caramelized bits of flavor stuck at the bottom. Let the alcohol evaporate slightly.
  1. Simmering to Richness: Stir in the beef stock and bring the mixture to a gentle boil. Reduce the heat and let it simmer for about 20-30 minutes. At this stage, you can add a splash of Cognac for extra complexity, seasoning with salt and pepper to taste.
  2. Cheesy Crust of Dreams: Preheat your oven’s broiler. Place the baguette slices on a baking sheet and toast them until golden brown. Meanwhile, ladle the hot soup into ovenproof bowls, placing the toasted bread on top of each serving. Generously sprinkle the grated cheese over the bread.
  3. The Grand Finale: Place the bowls on the baking sheet under the broiler until the cheese is bubbly and golden. VoilĂ , your French onion soup is ready to serve!
