Step 1

Heat oven to 200C/180C fan/gas Toss the cauliflower with the oil, thyme and seasoning, and spread out on a large baking tray. Roast for 15-20 mins until starting to soften and caramelise. Sprinkle the hazelnuts over the cauliflower and cook for another 5 mins until the nuts are lightly toasted and the cauliflower cooked through. Meanwhile, cook the pasta following pack instructions.

Step 2

Drain the pasta, reserving the cooking water, then return to the pan. Take the baking tray out of the oven and add the cauliflower and hazelnuts to the pasta, then stir in the Parmesan, egg, cream, parsley and 1 tbsp of cooking water. The heat from the pasta should be enough to just cook the egg without scrambling it. If the sauce is too thick, add a splash more cooking water. Check the seasoning and serve.
