Ingredients

  • 400 g Broccoli
  • 400 g Cauliflower
  • 200 g Onions
  • 2 Cloves garlic
  • Salt and freshly ground black pepper To taste
  • 750 ml Stock Good quality
  • 300 ml Milk
  • 120 g Cheddar cheese

To serve (optional):

  • 50 g Cheddar cheese
  • Croutons Homemade or shop bought

Instructions

  • Wash and chop the broccoli and cauliflower into large chunks. Finely slice your onion and crush the garlic.  
  • Put the broccoli, cauliflower, onions, garlic, stock and plenty of salt and pepper into a large saucepan. 
  • Bring to the boil and simmer for 15 minutes or until the vegetables are just cooked through.
  • Remove from the heat. Add the milk and cheese and blend until smooth.
  • Heat through again before serving if needed.
  • Top with the remaining grated cheese and croutons if using.

Notes

Vegetables: Either fresh or frozen is fine to use.
Stock: You can use vegetable or chicken stock in this recipe, depending on your preference. If you like a thinner soup, add slightly more, or less for a thicker heartier version. I like Marigold Boullion Powder.
To make in the slow cooker: Add the same ingredients and cook on HIGH for 3-4 hours or LOW for 5-6 hours. 
Optional toppings: You can put any cheese you like into this soup. It would be delicious with Parmesan, Stilton or Gruyere, or a combination. It is a great way of using up leftover bits of cheese in your fridge. Croutons would also be good.
Vegan: Simply omit the cheese in this recipe and swap the milk for a dairy-free version.
