Wash the herbs and remove the needles or leaves. Wash sea bream and dab dry. Rub inside and outside with salt and pepper. Sprinkle with lime juice. Spread half of the herbs and laurel into the belly opening of the giltheads. Cover with wooden skewers.
Carve the giltheads diagonally on both sides with a sharp knife and place them on an oiled baking tray. Clean and halve the garlic bulb. Place on the baking tray with the onion. Drizzle fish with oil. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 25 minutes. Sprinkle the remaining herbs over the fish approx. 5 minutes before the end of the baking time
Remove the giltheads and sprinkle with coarse salt. Garnish with rosemary, thyme and lime if desired. Serve with a fresh mixed salad and white bread
