Heat 1 tablespoon Olive oil in a large soup pan and once hot, add 1 Onion and 2 Garlic cloves. Cook on a gentle heat for 3-4 minutes.
Add 1 head Cauliflower, 1 head Broccoli and season with 1 pinch Sea salt and ground black pepper.
Add 700 ml Vegetable stock and bring to the boil. Simmer for 15 minutes.
Blend until smooth and then stir in 300 ml Skimmed milk, 100 ml Single cream and 100 g Mature cheddar.
Notes
You can add Cheddar, Stilton or Parmesan on top of this soup.
Use a really good quality stock cube, as you will taste the difference. If you are making this for kids, then use a low sodium stock cube.
To blend, try to use an immersion blender. If you are going to use a jug blender, then allow the cauli broccoli soup to cool completely before blending. You may need to do it in batches.
Taste the soup before serving and then add more salt if needed.
