    Easy whole sea bass recipe for entertaining or just a quick, elegant dish. Whole fish is oven baked in a roasting tin with Mediterranean flavours to create a one-sheet healthy dinner.

    So simple and yet so yummy: thank you for a lovely recipe Jill - Ben

    Baked Sea Bass - the 'Bar' is High!

    What we love about this recipe is its simplicity. In my humble opinion, baking the fish whole is the best way to cook sea bass, since it preserves its delicate flavours and keeps it tender. Don't forget the lemons, as they concentrate in flavour and become crispy.

    Known as 'Bar' in French, Alexandre Dumas had something to say about this fish in his famous Dictionnaire de Cuisine.

    Any sea bass over 2-3 kilos is no longer delicate in flavour. I caught one in Trouville weighing 23 kilos; it had lost all of its flavour.

    Sea Bream vs Sea Bass

    Sea bream and sea bass fish are similar, but their appearances differ. Sea bass is longer and thicker, while sea bream is slimmer.

    I score the skin and stuff baked sea bass before roasting to add extra flavour. On the other fin, Sea bream's skin is better suited for a different preparation, like Bream baked Provençal style in tomato sauce.

    Mediterranean Fish Recipes

    Both sea bass and sea bream pair well with flavours of garlic, tomato and herbs.

    If you love Mediterranean food, try these roasted fresh sardines, stuffed with lemon and breadcrumbs. They're absolutely delicious served with a Provençal rosé from Bandol (post coming!) Likewise, in a one-pot dish, try this monkfish stew, known as lotte à l'américaine.

    For more Mediterranean-style tomato recipes,
    see the guide to tomatoes.

    Whole Sea Bass Recipe

    To prepare the whole fish, wash and pat it dry. It goes without saying, ensure the fish is as fresh as can be. Eyes should be clear and shiny (if they're dull, avoid it, as it probably doesn't smell fresh, either.)

    sea bass fish laid whole on a baking dish with potatoes, cherry tomatoes and herbs

    Lay it on a large roasting tin on baking parchment.
    Rub the sea bass with 2 tablespoons of the olive oil.

    Avoid using aluminium foil for baking, as it can contaminate food when combined with lemon (see the National Library of Medicine).

    removing parsley leaves from the stalks before stuffing a whole sea bass fish

    Score the skin 3-4 times on top of the fish and stuff each cavity with thyme, garlic and a lemon slice.
    Stuff the fish with 3 lemon slices, the remaining garlic, and parsley stalks.
    Reserve the parsley leaves for decoration, to preserve their vitamin C content.

    For more, see the guide to aromatic fresh herbs
    and potatoes for best varieties.

    Surround the fish with roughly chopped potatoes, cherry tomatoes, the rest of the thyme and season with salt and pepper.
    Dribble over the remaining olive oil and bake for 20-25 minutes.

    When serving from the oven, use a sharp pie slice and knife to gently cut through to the bone and lift the fish off for each person.

    Another Delicious Way to Cook Sea Bass

    If you prefer without the bones, head and tail (like my daughter!), then get your fishmonger to prepare the sea bass as 2 large fillets. It's another delicious way to cook it - no bones about it, and even easier!

    Simply follow the recipe and place the stuffing in the middle. in the winter, without the tomatoes, I often place a few spinach leaves with the lemon and cook in the same way, surrounded with chopped potato. The result is extra crispy potatoes and still with the fish skin.

    How to Serve

    This delicate sea bass recipe can be served as is with its Mediterranean flavours. Alternatively, it pairs well with sautéed green beans with garlic or a simple green salad.

    Wine Pairing: it pairs well with a full-bodied chilled French white Burgundy Chardonnay, such as Chablis or Mersault. From the Rhône, Crozes-Hermitage or Saint-Joseph also pair with the delicate fish. New World younger Chilean Chardonnays, as well as those from California and South Africa, are good options.

    Equipment

    • 38x28 (15x11 inch) roasting tin large enough to hold the whole fish

    Ingredients
     

    • 1 whole 1.5-1.8kg (3-4lb) sea bass scaled and gutted
    • 2 cloves garlic sliced
    • 2 lemons unwaxed/organic, sliced with skins
    • 2 sprigs fresh lemon thyme
    • 2 sprigs fresh parsley stalks and leaves separated

    Prevent your screen from going dark

    Instructions
     

    • Preheat the oven to 200°C/400°F (180°C fan/Gas6). Wash the fish and pat it dry with kitchen paper.
    • Lay the fish on a large roasting tin on baking parchment. Rub with 2 tablespoons of the olive oil. Score the skin 3-4 times on the top of the fish and stuff each cavity with thyme, garlic and a lemon slice. Stuff the fish with 3 lemon slices, the rest of the garlic and parsley stalks (keep the leaves aside for decor, to keep their vitamins).
    • Surround the fish with roughly chopped potatoes, tomatoes, rest of the thyme and season with salt and pepper. Dribble over the rest of the olive oil and bake for 20-25 minutes.
    • Sprinkle over the finely chopped parsley leaves and serve.

    Notes

    Serving suggestions with Baked Sea Bass

    With a delicate fish and Mediterranean flavours of tomato, herbs and garlic:
    • Vegetable sides: serve with sautéed green beans with garlic or a simple green salad.
    • Wine: pairs well with a full-bodied chilled Chardonnay: Burgundy, Rhône or New World younger Chilean Chardonnays work well, as does from California and South Africa.
    Another Way of Serving: if you prefer without the head, tail and middle bone, then ask your fishmonger to prepare two large fillets from the sea bass and follow the same recipe. Add more whole garlic cloves and diced potatoes around the fish and the whole lot roasts beautifully.

        Agreed - it’s so simple, Dave. When fish is so good it doesn’t need that much. Of course you can freeze it - sealed well up to a month. Thanks for asking - I’ll add it to the post.
