1 tbsp freshly grated parmesan or pecorino, to serve
salt and freshly ground black pepper
pasta (eg elicoidali, a medium-sized, ridged pasta tube)
Gently fry the onions in olive oil for about 15 minutes until soft and beginning to caramelise. Add the garlic and continue to cook for 2 minutes. Add a splash of water (or stock) if it looks as if the onions are "catching".
Cook the pasta according to the packet instructions. Drain, reserving a little of the cooking water.
Add the sliced sausage to the onions and fry for 2-3 minutes until the cut surfaces have coloured a little.
Pour over the stock and cook for another 2 minutes before adding the lemon juice and cream. Stir well to combine. If the sauce looks too thick, then add a splash of the pasta cooking water.
Check the seasoning. Add the pasta and stir well to combine, ensuring the pasta is warmed through. Serve with grated cheese.
