Pan-frying is a great option for cod fillet or loin as there is time to produce a lovely crispy skin without overcooking the delicate, flaky flesh. This is the way cod and similar white fish are often cooked in restaurant kitchens and is very simple to do at home.
To ensure crispy skin on your pan fried cod, dry the fillets with kitchen roll before seasoning them with salt. Don't put too much oil into the frying pan and make sure it has a chance to get hot before adding the fillets.
If you are cooking a very thick loin or fillet, cook skin-side down in the pan until the skin is golden, then turn over and finish cooking in an oven preheated to 180°C/gas mark 4 for 6 minutes.
If desired, add a squeeze of lemon juice to the pan before serving to ‘brighten’ the final flavour of the cod.
Once you have turned the fish over, James Sommerin suggests adding a knob of butter to the pan and basting the fish for the final 2–3 minutes to add extra flavour and keep the fish moist.
