🛒 Ingredients

5 servings

5
  • 1 whole bluefish (about 3.3 lbs / 1.5 kg), butterflied by your fishmonger
  • 1 garlic clove, finely minced
  • 1 small onion, finely chopped
  • 1 ripe tomato, finely diced
  • Fresh flat-leaf parsley, to taste, chopped
  • Fresh cilantro, to taste, chopped
  • Juice of 1 lemon
  • Fine sea salt, to taste
  • Extra virgin olive oil, for the pan and finishing

Directions

  1. 1

    Ask your fishmonger to butterfly the fish: remove the backbone and open it flat like a book, skin side facing out.

  2. 2

    Generously brush a baking dish with olive oil and place the fish skin-side down.

  3. 3

    In a bowl, combine garlic, onion, tomato, parsley, cilantro, lemon juice and salt. Mix well and spread evenly over the entire flesh of the fish.

  4. 4

    Let the fish marinate at room temperature for 30 minutes so the flavors fully penetrate the flesh.

  5. 5

    Drizzle with olive oil, cover tightly with aluminum foil, and bake in a preheated oven at 356°F (180°C) for 30 minutes.

  6. 6

    Remove the foil and continue baking for a further 10–15 minutes, until the cooking juices have evaporated and the surface is lightly golden.

  7. 7

    Serve immediately alongside white rice, roasted vegetables, or a crisp green salad.

💡 Chef's Tip

For an indulgent finish, spoon a homemade shrimp sauce over the fish just before serving. Laying thin lemon slices directly on the flesh before baking delivers an even brighter citrus aroma.
