Halibut Confit With Leeks, Coriander, and Lemon

This elegant halibut confit with leeks, coriander and lemon is a wonderfully light way to enjoy white fish. By slowly poaching the halibut in a coriander-infused olive oil, the flesh remains remarkably moist and tender, absorbing the bright notes of citrus and the earthy warmth of the toasted spice. It is a sophisticated yet simple one-pan dish that celebrates clean flavours and gentle cooking techniques.

As a diabetes-friendly main course, this recipe prioritises healthy fats and high-quality protein without sacrificing depth of flavour. The softened leeks provide a subtle sweetness that pairs perfectly with the flaky fish, making it a nutritious choice for a midweek dinner or a relaxed weekend lunch. Serve it just as it is, or with a side of steamed seasonal greens for a complete, heart-healthy meal.

How to make Halibut Confit With Leeks, Coriander, and Lemon

Preheat oven to 191°C. Coarsely grind 1 tablespoon coriander seeds in a spice mill or with a mortar and pestle. (Alternatively, you can coarsely chop with a knife.)

Toss leeks, coriander sprigs, oil, half of lemon slices, and 2 teaspoons ground coriander in a large roasting pan; season with salt. Roast, tossing occasionally, until leeks are tender and starting to brown, 15-20 minutes. Remove roasting pan from oven and carefully pour infused oil into a large heatproof measuring cup.

Reduce oven temperature to 135°C. Season halibut with salt and arrange over leeks in roasting pan. Top with remaining lemon slices and ground coriander and pour infused oil over fish. Roast until halibut is just cooked through and starting to flake, 30-35 minutes.

Cut halibut into large pieces and serve with leeks and lemon topped with chopped coriander seeds and coriander leaves.

Do ahead: Halibut can be roasted 1 hour ahead. Let cool and cover.
