Impress your vegetarian guests at Christmas with this elevation of the classic cauliflower cheese side – adding earthy, meaty truffle oil gives an even richer and more delicious flavour. A Christmas side dish that's really hard to beat!
- Preheat the oven to gas 4, 180°C, fan 160°C.
- Bring a large pan of water to the boil, then add the whole cauliflower. Simmer for 8-10 minutes before transferring the cauliflower to ovenproof baking dish with a slotted spoon. Drizzle with the truffle oil and set aside.
- Make the cheese sauce. Melt the butter in a small pan over a medium heat. Stir in the flour, mustard powder and cayenne. Mix to a paste. Remove the pan from the heat and slowly whisk in the milk. Return to the hob and cook, stirring constantly, over a medium heat until the sauce begins to thicken. Remove the sauce from the heat and stir in three-quarters of the grated cheese. Season to taste.
- Pour the cheese sauce over the cauliflower and top with the remaining cheese. Bake in the oven for 25-30 minutes until bubbly and golden brown. Serve immediately.
