Classic risotto needs constant stirring but this baked version needs hardly any attention as it cooks gently in the oven. To jazz it up a bit: When you add the remaining butter and cheese, stir in some shredded roast chicken. Heat through for 1-2min. Fry 2oz cubed pancetta or smoked streaky bacon with the onion and garlic. Stir in some fresh, chopped basil, thyme or baby spinach before serving.
