Step 1

If the fish hasn't been gutted and scaled, do so.

Step 2

Heat the oven to 400°F (200°C). Prepare a roasting tin.

Step 3

Mix the butter, 2 minced garlic cloves, chopped rosemary and chopped thyme very well. Season well with salt and pepper.

Step 4

Spoon the compound butter into the fish cavities. Stuff the inside of the fish with lemon triangles (you will probably not be able to fit all of them into your fishes) and rosemary sprigs. Drizzle the fish with olive oil and sprinkle with salt. You can slash the fish two to three times if you like.

Step 5

Place the fish in the prepared tin, along with the extra thyme, garlic and remaining lemon slices. Bake for 20-25 minutes (a large sea bream takes about 25 minutes, branzino is probably ready after 20).

Step 6

In the meantime, mix the chopped tomatoes, capers, olives and parsley. Add enough olive oil to create a nicely dispersed condiment. Serve with the hot fish.
