I love this one-tray dinner; it feels elegant but easy, and worthy of both a midweek meal and if you are entertaining. The punchy anchovy and garlic butter does all the hard work, and gives the impression of more effort than was actually exerted. But what to serve it with, I hear you ask? Well, it wouldn’t be out of place with creamy mashed potato, buttery polenta or a salad. Just make sure to baste the fish halfway through cooking, to get all the flavour and juices back into it.
