Preheat the oven to gas 6 / 200C / 400F and line a roasting tin with foil

Spread out the squash, drizzle with the oil and roast for 30 minutes until tender

Before the squash finishes roasting, cook the pasta as per the packet instructions

Fry the bacon and garlic until crispy

Put the squash in a blender with the grated cheese (keep a handful back for topping) and the cream cheese

Puree with enough of the reserved pasta water to make a smooth sauce

Season to taste with black pepper

Drain the pasta then pour the squash sauce over it and gently mix to coat

Pour into an ovenproof dish and top with the remaining cheese

Bake in the oven (same temperature) until the cheese melts on top, then serve with salad or green vegetables.
