Make this simple French-style soup in your slow cooker. With only 15 minutes prep you can make this tasty soup with minimal effort


  • 4 tbsp olive oil
  • 6 medium onions, finely sliced
  • 1 tbsp castor sugar
  • 3 cloves garlic, crushed
  • 200mls dry white wine
  • 600mls beef or chicken stock, boiling
  • 2 tbsp Worcester sauce
  • 4 large slices baguette
  • 100g grated Gruyere or Edam cheese
  • 2 tbsp Brandy, optional
  • salt
  • freshly milled black pepper

For a healthier version serve the soup without the cheese-topped toast


  1. Place the onions, oil, sugar, garlic into the stoneware and heat gently on the hob. Once sizzling, stir well and cook for 10 minutes to soften slightly, then add the wine and warm through.
  2. Place into the heating base, setting on low. Pour in the boiling stock, Worcester sauce, salt and pepper and mix well. Place the lid on and cook for 4-5 hours.
  3. Meanwhile, toast the bread on both sides, then pile on grated cheese, grill until melted and golden.
  4. To serve, stir the Brandy into the soup, then ladle the soup into hot bowls and top with the cheese crouton. Sprinkle with chopped parsley.
