Instructions

Roasted Fish

  • Rinse and clean the fish as described in the post.
  • Mix the olive oil, salt, pepper, oregano, chilli pepper and half a lemon's juice in a bowl.
  • Spread the mixture all around the fish, including the cavity with an egg brush.
  • Stuff each fish cavity with a parsley spring and a garlic clove and several slices of onion.
  • Place the fish in a single layer in an oven-proof tray.
  • Roast in a preheated oven at 230°Celsius (440° F) for about 20 minutes, depending on the size of the fish.

  • Then mix and coat with the seasonings, except for salt.

  • Start baking in a sheeted oven tray 10 minutes before placing the fish in the oven in a separate tray.
  • Season with salt to taste and serve.

Notes

Mackerel, sea bass, bonito, sea bream and red mullet are good choices for roasting whole fish in the oven. Pictures show sea bass. 
Do not cover the fish when in the oven. The time required will depend on the size and the weight of the fish plus the performance of the oven. Roughly the rule is to bake for 10 minutes if the fish is 2.5 cm (1 inch)  thick and 20 minutes if 5 cm (2 inches) thick. 
When eating make sure to watch out for fish bones, some fish might have more than others. Generally they are on the sides, the one in the middle easy to locate. Also consider munching the tail and the neck and cheeks on the head.
