Ingredients Method Notes

Ingredients
  

  • 100 g / 3.5oz unsalted butter
  • 1.25 kg / 2.5 lb brown / yellow onions (, peeled, halved, thinly sliced top to bottom)
  • 3/4 cup (185ml) dry white wine
  • 2 tbsp flour (, plain / all purpose)
  • 1.5 litres / 6 cups / 1.5 quarts good quality beef broth./stock OR chicken (, low sodium/salt reduced)
  • 2 dried bay leaves (or 3 fresh)
  • 3 sprigs fresh thyme
  • Salt and pepper
  • 6-8 slices French baguette (or other softish bread)
  • 100 g / 3.5 oz gruyere (or mozzarella cheese, or other melting cheese of choice)

Method
 

  1. Melt butter in a heavy based casserole pot over medium heat. Add sliced onions and stir to coat in butter.
  2. Cook for 30 minutes on medium-low, stirring every few minutes, until the onions have softened and are semi-transparent.
  3. Turn heat up to medium or medium-high. Add salt, and cook for a further 20-30 minutes, stirring more regularly, until onions are deep golden and sweet.
  4. Add white wine (if using) and simmer rapidly for 2 minutes until mostly evaporated, scraping the bottom of the pot.
  5. Sprinkle flour over the onions and cook for 1 minute, stirring constantly.
  6. Pour in the beef broth, and add thyme and bay leaves. Bring to a simmer.
  7. Ladle soup into oven-safe bowls. Top each with baguette slices and a generous amount of Gruyere cheese.
  8. Broil until cheese is melted, bubbly, and golden brown. Serve immediately.

Notes

- For deeper flavor, use homemade beef stock if possible.
- Ensure onions are sliced thinly and evenly for consistent caramelization.
- Broil carefully to avoid burning the cheese; watch closely!
- Serve immediately while the cheese is perfectly melted and bubbly.
