Step 1

Heat the oil and butter in a large deep frying pan. Add the onion and cook gently for 5 minutes until softened. Stir in the mushrooms and garlic and cook gently for 2-3 minutes.

Step 2

Stir in the rice to coat with the onion and mushroom mixture. Pour in the wine and cook over a moderate heat for about 3 minutes, stirring from time to time, until the wine is absorbed.

Step 3

Reduce to a gentle heat. Add the tomatoes and 125ml/ 4fl oz of the stock and cook for about 5 minutes until the liquid is absorbed. Pour in a further 125ml/4fl oz stock and continue cooking until absorbed. Repeat with the remaining stock, until it is all absorbed and the rice is creamy and tender.

Step 4

Stir in the parsley and half the parmesan. Season to taste. Scatter the spinach over the risotto. Cover and cook gently for 4-5 minutes until the spinach has just wilted. Serve immediately sprinkled with the remaining parmesan.
