Whole Snapper

This elegant whole roasted red snapper is a bright and aromatic dish that makes a stunning centrepiece for any dinner table. Roasted with zesty lime juice, dry white wine, and fragrant coriander, the fish remains beautifully moist while absorbing the savoury flavours of softened Spanish onions and garlic. Using whole fish not only preserves the delicate texture of the meat but also creates a sophisticated dining experience that feels special yet remains remarkably simple to prepare.

As a diabetes-friendly main course, this recipe focuses on high-quality protein and heart-healthy fats from olive oil. The light, citrus-based sauce provides a punchy depth of flavour without the need for heavy starches or sugars. Served with a side of steamed seasonal greens or a crisp salad, it offers a nutritious and balanced meal that is as wholesome as it is delicious.

  • 60ml olive oil

  • 2 large cloves garlic, peeled and chopped, plus 4 cloves whole garlic, peeled

  • 1 cup dry white wine

  • 2 bay leaves

  • 6 tablespoons unsalted butter

  • Juice of 2 lemons

  • 2 (4-pound) whole red snappers, cleaned, with head and tail intact

  • 1 small tomato, sliced

  • 2 ribs celery, halved crosswise

  • Juice of 10 Key limes or small thin-skinned limes, plus 4 limes cut into quarters for serving

  • 1/2 cup coarsely chopped fresh coriander

  • 1 (12- by 18-inch or larger) roasting pan

How to make Whole Snapper

Preheat the oven to 204°C.

In a large sauté pan over moderate heat, warm the oil. Add the onions and sauté, stirring occasionally, until softened, about 5 minutes. Add the chopped garlic and sauté, stirring occasionally, for 1 minute. Add 3/4 cup wine and the bay leaves and bring to a simmer. Continue simmering until the onions are tender and the wine is slightly reduced, about 3 minutes. Whisk in the butter then remove the pan from the heat and whisk in the lemon juice.

Arrange the snappers, side by side, in a 12- by 18-inch or larger roasting pan. Stuff the cavity of each fish with about 40g the onion mixture, along with the whole garlic, tomato slices, and celery. Season to taste with salt and pepper. Spoon the remaining onion mixture over the fish then pour half the lime juice on and around the fish and add 475ml water to the pan. Wrap the pan snugly with foil and roast for 25 minutes. Remove the foil and continue roasting until the fish is cooked through, 20 to 25 minutes longer. Remove any onion from the top of the fish then carefully transfer the fish to a large serving platter (do not discard the onion or juices remaining in the pan). Drizzle the remaining lime juice over the fish and cover loosely with foil to keep warm.

Scrape the onion and juices from the roasting pan into a medium saucepan. Add the remaining 60ml white wine and 60ml water, and bring to a simmer. Continue simmering until slightly reduced, then pour through a fine-mesh strainer.

Garnish the fish with coriander and serve with the reduced pan sauce and lime wedges.
