Batmans mackerel with melted onions and black olives

In Dorset, mackerel usually arrive in May or June, as they chase the sand eels and whitebait inshore, sometimes chasing them right up on to the beach. They may disappear for a few weeks in August, before returning with a vengeance to gorge on the sprats. Many skippers have a rod or two and there a spot of fishing is a good way of whiling away your surface interval and Mackerel are dead easy to catch.

This is one of my favourite Mackerel recipe’s.


To serve 4 as a starter, 2 as a main course.

Cut the fillets from either side of 2 whole, ungutted mackerel, and season them with a little salt and pepper.

Slice 2ミ3 large onions ミ enough almost to fill a large frying pan (they will reduce to about a quarter of their volume as they cook).

Heat a film of olive oil in the pan and add the onions with 3 or 4 bay leaves and a sprig or two of thyme.

Sweat the onions gently, tossing and stirring frequently, for at least 10 minutes, until they are

softened and golden, very tender and sweet. Don’t let them burn. Add a handful of black olives, stoned and roughly chopped, and a splash of white wine.

Cook for a few minutes until the wine has evaporated, then season with a little salt and pepper.

Push the onions to the edges of the pan, making space for the mackerel fillets to cook in the middle.

Lay the fillets in the pan, flesh-side down. Turn them after a few minutes to cook the skin side, spreading the onions over the fish to help the transfer of heat. They should be cooked through in 7ミ8 minutes.

This dish can be served hot, straight from the pan, but is arguably even better at room temperature.

Serve with a good chilled rosテゥ ミ which will taste particularly fine with the rich, oily fish, sweet onions and salty olives.
