Whisk together olive oil, freshly squeezed lemon juice, minced garlic, and season with salt and pepper. Set a small amount aside for serving.
2 tablespoons olive oil, 1 clove garlic, 1 lemon, sea salt, freshly ground black pepper
Preheat the oven to 200°C (400°F). Place the cleaned fish on a board. Pour a bit of the marinade inside the cavity, rubbing it gently along the flesh (as shown in your photos). This helps the flavour soak in as it cooks. Brush more marinade over the outside of the fish, making sure it gets into the shallow cuts on the skin.
1 whole Sea Bream
Tuck a lemon slice, a sprig of thyme or rosemary, and a sprinkle a bit of parsley inside the cavity. These herbs release their aroma slowly in the oven.
1 lemon, 1 sprig rosemary, 1 sprig thyme, Handful of fresh parsley
Line a baking dish or baking tray with baking sheet or aluminum foil. Place the sea bream on top and drizzle a little extra marinade around it. Scatter a few thin slices of garlic or lemon around the fish if you like.
Once the preheated oven is ready, bake the fish for 15–20 minutes, depending on size. Avoid overcooking — the fish is ready when the flesh flakes gently and looks opaque. If you prefer the skin a little crispy, broil for the last 30–60 seconds.
Once the fish is cooked, transfer it to a plate and serve immediately with a spoonful of the reserved marinade on top.
