Ingredients
  

Base Ingredients

  • 100 g unsalted butter
  • 1.25 kg brown / yellow onions peeled, halved, thinly sliced
  • 185 ml dry white wine optional
  • 2 tablespoon flour plain / all purpose
  • 1.5 litres beef broth or chicken, low sodium
  • 2 dried bay leaves optional
  • 3 sprigs fresh thyme optional
  • Salt
  • Pepper

Cheesy Toast

  • 6 - 8 slices French baguette or other softish bread
  • 100 g gruyere cheese or mozzarella, or other melting cheese
  • Fresh parsley or thyme leaves for garnish, optional

Instructions
 

Caramelise Onions

  • Melt butter in a heavy based casserole pot over medium heat. When it starts to foam, add onions and stir to coat in butter.
  • Turn heat down to medium low. Cook for 30 minutes stirring every few minutes, until the onions have softened and are semi-transparent.
  • 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.

Make Soup

  • Add wine, then simmer rapidly for 2 minutes until mostly evaporated, stirring to scrape the bottom of the pot.
  • Sprinkle flour over the onion and cook for 1 minute.
  • Add broth, thyme and bay leaves.
  • Cover, lower heat so it’s simmering gently then simmer for 30 minutes.
  • Season to taste with salt and pepper. Ladle into bowls. Top with 1 or 2 slices of cheesy toast.

Cheese Toast

  • Preheat grill / broiler to high. Toast each side of bread until light golden.
  • Top bread with cheese, then grill until melted and some brown spots appear.

Notes

For slow cooker caramelized onions, see recipe video for details on technique. Use quality broth for best flavor.
