Step 1

Melt the butter and 1 tbsp of the oil in a large pan with a well-fitting lid over a gentle heat. Add the onion, garlic and butternut squash. Season well and toss to coat before covering and leaving to cook for 25-35 mins, occasionally stirring or shaking the pan to mix, until the squash is very soft.

Step 2

Meanwhile, heat the remaining oil in a small frying pan and cook the rosemary for 1-2 mins, then set aside. When the squash is almost done, cook the linguine following the pack instructions. Drain the pasta, reserving 2-3 ladles of the pasta cooking water.

Step 3

Add the cream to the butternut squash mix and blitz using a hand blender to a smooth consistency. Stir in the parmesan, then the pasta and pasta water. Drizzle over a little of the rosemary oil, add a good grinding of black pepper to taste, and serve.
