  • 1.5 tbsp olive oil or avocado oil
  • 1 cauliflower ~ 4 cups
  • ½ cup unsweetened almond milk
  • ½ cup cashews
  • 1 red onion
  • 4 garlic cloves
  • 1 tsp mixed dried herbs
  • 3 cups vegetable stock
  • ¼ cup nutritional yeast
  • Toppings optional
  • Finely chopped chives
  • Toasted seeds


  1. Preheat oven to 350F.
  2. Cut cauliflower into bite sized florets and place on a baking tray. Coat in 1 tbsp olive oil and salt and pepper.
  3. Place in the oven for 30-40 minutes until they are starting to go brown and crispy on the edges. Give them a toss half way through.
  4. Make the cashew cream by mixing the cashews and almond milk in a high speed blender until smooth. (If you don’t have a high speed blender you will need to soak the cashews in hot water for half an hour, then drain).
  5. Finely chop the red onion. Heat ½ tbsp oil in a skillet/pan on medium heat then add the onion, let cook for a few minutes.
  6. Add finely chopped garlic and dried herbs, stir and cook for a further couple of minutes.
  7. Add the vegetable stock and roasted cauliflower. Bring to a gentle simmer for 5 minutes.
  8. Add the cashew cream and nutritional yeast and stir.
  9. Blend until smooth, add more water if it needs thinning. Taste and season with salt and pepper.
  10. Optional - top with some chopped chives and toasted seeds.

Recipe Notes

You can sub nutritional yeast for vegan parmesan or 1 heaped tbsp vegan cream cheese.
Best eaten straight away but will keep in the fridge for 2-3 days in an airtight container.
