Roasted Halibut with Garlic Sauce

This elegant roasted halibut with garlic sauce is a wonderful choice for a light yet satisfying main course. Halibut is a prized white fish known for its firm texture and delicate, sweet flavour, which stands up perfectly to roasting. By topping the fillet with a simple, punchy garlic and olive oil infusion, the fish remains beautifully moist and flaky while developing a rich, savoury crust in the oven.

As a diabetes-friendly dish, this recipe focuses on high-quality protein and healthy fats without the need for heavy carbohydrates. It is incredibly quick to prepare, making it an ideal mid-week meal that feels special enough for a weekend dinner party. Serve it alongside a crisp green salad or some steamed seasonal greens and a squeeze of fresh lemon to balance the creamy garlic topping.
