Courgette and Smoked Mackerel Carbonara

Another recipe from Save with Jamie. I actually really love this book, it has so many interesting recipes in it, ideal to use up leftovers and gluts of produce. This was a very tasty variation on carbonara and one I would definitely make again.

Courgette and Smoked Mackerel Carbonara (from Save with Jamie - Jamie Oliver)
(Serves 4)

320g dried penne
1 onion, finely slice
1 large courgette, cut into quarters and then sliced
2 sprigs fresh rosemary, leaves chopped
130g smoked boneless mackerel fillets, flaked
olive oil
2 large eggs
100ml semi-skinned milk
40g Parmesan cheese
1 lemon

Bring a pan of water to the boil, add the pasta and cook according to packet instructions.

Heat a tbsp oil in a frying pan over a medium heat and add the onions and courgette, season and cook, stirring occasionally, for 5 mins. After 5 mins add the rosemary and mackerel and cook, tossing occasionally, for another 5 mins or until golden.

Meanwhile, whisk the eggs and milk together, then grate in the Parmesan. Reserving a cupful of cooking water, drain the pasta and toss into the mackerel pan. Take the pan off the heat for a few secs and stir in a good splash of cooking water to cool it down. Quickly pour in the egg mixture and shake and stir together until thickened, silky and evenly coated. Divide between 4 plates grate over a little extra parmesan, a sprinkle of pepper and a squeeze of lemon juice, serve.
