Method

  1. Preheat the oven to gas 4, 180°C, fan 160°C. In a saucepan, whisk the cornflour and mustard together until smooth. Gradually whisk in the milk and cream, then stir through the garlic, rosemary, sea salt and black pepper. Bring to a simmer for 5 mins, whisking continuously, until you have glossy sauce.
  2. Pour a small amount of the sauce into an ovenproof baking dish. Layer up the celeriac and butternut squash, pouring some of the sauce on top of each layer.
  3. Pour over the remaining sauce and finish with a layer of cheese and thyme leaves.
  4. Cover with foil and roast for 1 hr, then uncover and roast for a further 15 mins, or until a knife easily passes through. Leave to rest for 10 mins before serving.
