PREPARATION METHOD AND PROCEDURE

PREPARING THE ONIONS

  • Slice the onions thinly and evenly to ensure consistent caramelization.

CARAMELIZING THE ONIONS

  • In a large heavy-bottomed pot, heat the butter and olive oil over medium heat.

  • Add the sliced onions and cook slowly, stirring regularly until deeply golden and sweet.

  • Reserve a small portion of the caramelized onions for the final garnish.

BUILDING THE SOUP BASE

  • Add the minced garlic and cook for 1 minute until fragrant.

  • Sprinkle in the flour and stir well.

  • Cook for 2 minutes to remove the raw flour taste.

  • Stir in the demi-glace and mix thoroughly until fully incorporated into the onion mixture

  • Deglaze with vegetable stock and reduce slightly.

SIMMERING THE BROTH

  • Bring to a gentle boil, then reduce the heat and simmer for 30 minutes.

  • Season with salt and black pepper.

  • Remove the thyme sprigs and bay leaves.

PLATING

  • Ladle the hot soup into ovenproof matte black bowls.

  • Place toasted baguette slices on top.

  • Cover generously with grated Gruyère cheese.

    BAKING

  • Broil or bake at 220°C until the cheese is melted, golden, and bubbling

FINAL PLATING

NOTE

  • Caramelize the onions slowly over medium to low heat until they develop a deep amber color and natural sweetness, which forms the soul of this classic French soup.

  • Incorporating demi-glace into the onion base enriches the broth with exceptional depth, body, and a luxurious restaurant-quality finish.
