Preheat the oven to 200°C fan (220°C conventional, gas 7). Cut the cauliflower into quarters, leaving the leaves and core on (less waste, more texture and flavour). Simmer in boiling water for 5 minutes, then drain really well.
Meanwhile, soak the 50g cashews in hot water for 5 minutes. Drain, then add to a blender cup with the 200ml almond milk, 4 tbsp nutritional yeast, 1 tbsp olive oil, 1 tsp Dijon mustard, salt and pepper and blend until smooth.
Put the drained cauliflower in a baking dish and pour over the cheesy sauce.
Bake for 15 to 20 minutes, until golden and bubbling.

Notes
What goes well with cauliflower cheese?It is a classic side for a roast. Serve it with my Roast Parsnips, Rosemary Roast Potatoes or my Christmas Nut Roast.What is the cheese sauce made of? Cashews, nutritional yeast and unsweetened almond milk, plus a little olive oil, Dijon mustard, salt and pepper.Why does it go watery? Usually the cauliflower is overcooked or not drained well. Simmer for just 5 minutes (less for a small cauliflower) and drain really well.What if I don't have any nutritional yeast?Scatter grated vegan cheese over the top before baking.To Store: Keep in an airtight container in the fridge for up to 2 days. Reheat once until piping hot.To Freeze: Assemble, then freeze before baking for up to 3 months. Defrost in the fridge overnight and bake for 25 to 30 minutes, until golden and piping hot.
