Creamy garlic & sprout spaghetti

Bring a large saucepan of salted water to the boil. Add the pasta and cook for 1 minute less than pack instructions. Just before draining, scoop out a mugful of the cooking water.

Meanwhile, heat the oil in a large frying pan over a medium-high heat. Add the shallots and fry with a pinch of salt for 2 minutes, then add the sprouts and fry for another 3-4 minutes until softened but still vibrant green.

Add the spaghetti and 100ml pasta water to the pan and spoon in the Boursin. Toss together until you have a smooth, silky sauce. Add the lemon zest and a squeeze of lemon juice, then season, sprinkle over the walnuts and serve immediately
