Step 1

Cook the pasta following pack instructions and reserve a mugful of the cooking water. Heat the leftover chicken fat in a large frying pan over a medium-high heat. Stir in the onion and cook for 8-10 mins until softened. Mix in the chilli, garlic and tomato purée, then cook for a further 5 mins until the purée has caramelised. Pour in the wine and simmer for 2-3 mins until almost completely reduced.

Step 2

Mix in the spinach and leftover chicken along with a splash of the reserved cooking water. Cook for 3-4 mins until the chicken is heated through, then squeeze in some lemon juice, and add most of the basil, the crème fraîche and cooked pasta. Mix in a splash of cooking liquid to bring it all together, then season to taste, adding more lemon juice if needed. Scatter over the remaining basil to serve.
