Cooking instructions

Oven Roast

HOW TO OVEN ROAST A WHOLE FISH: Fish likes heat. Preheat your oven to 220˚C/200˚C Fan/425˚F/Gas Mark 7. Rub your fish with olive oil, then salt, and make a few slashes in the flesh, right down to the bone – diagonal slashes look good.  Add some rosemary or thyme to the slashes if you have some to hand or stuff the herbs into the cavity of the fish.

Put the fish on a roasting tray and place in the oven.  As a guide, (all ovens are different, you know yours better than me) a 450g whole fish will feed 1 person and take around 12-15 mins to cook.  A 1 – 1.2kg fish, serving 4, will take around 30 minutes. 

To make an instant sauce add the following to the baking tray:  chopped fresh tomatoes, a pinch of dried chilli flakes, a good splash of white wine, a few slivers of sliced garlic, and herbs such as thyme, bay, parsley or chives. Serve the cooked fish with lemon wedges.

 

HOW TO OVEN ROAST A CHOP/CHUNK OF FISH: Fish likes heat. Preheat your oven to 220˚C/200˚C Fan/425˚F/Gas Mark 7. Rub your fish with olive oil, season with salt and place in a roasting dish. Place in the preheated oven for 10 minutes, then remove from the oven and spoon 2tbsp of Rockfish flavoured butter over the fish. Put back in the oven for 5 minutes and then remove. Put your fish on a plate and pour over the warm butter from the roasting dish.  

Panfried

HOW TO: To pan fry a piece of fish, use a non-stick pan or one that you know is non-sticky! Heat the pan and add a few tablespoons of a neutral oil (vegetable oil will do).  When the oil is hot, lay the fish in the pan. For hake, bass and salmon put it in the pan skin-side down. For cod, thick white fish, flat fish fillets and gurnard lay them flesh-side down. 

Allow the fish to sizzle and don’t be tempted to turn them, let the pan do the work, you will see the heat rise and the fish will firm up. If it’s a thin piece of fish turn it and cook for just a minute or so and it's done. If the fish is thicker, after you've turned it place in a pre-heated oven set to 200˚C/180˚C Fan/400˚F/Gas Mark 6 for about 3-4 minutes to finish the cooking.

Why is Rockfish fish so fresh?

At Rockfish, we pride ourselves on delivering the freshest fish you can find. Our location right on the quayside means we’re just steps away from the day’s catch. This proximity allows us to inspect and select only the finest quality fish, ensuring that what reaches your plate is nothing short of exceptional. From the moment the fish is landed, it takes just a short 17-meter journey to our dedicated fishmonger unit, where it’s expertly prepared within hours.

How is the fish prepared?

To maintain peak freshness, we portion and vacuum-pack every piece of seafood on the same day it’s landed. This keeps the fish in pristine condition, clean, and easy to handle for cooking. Whether it’s destined for our restaurants or your home, you can trust that Rockfish fish is as fresh as it gets—straight from the sea to your table in record time.
