Roasted Halibut with Walnut Crust

This elegant roasted halibut with walnut crust is a wonderful way to enjoy fresh white fish. It features a bright, herbaceous topping made from toasted walnuts, fresh parsley and basil, providing a satisfying crunch that contrasts beautifully with the delicate, flaky halibut. By roasting the fish at a high temperature, the natural juices are locked in, ensuring a moist and succulent result every time.

As a heart-healthy main course, this dish is rich in omega-3 fatty acids and relies on fresh herbs for maximum depth of flavour. It is an ideal choice for a sophisticated mid-week supper or a light weekend lunch when served alongside steamed seasonal greens or a crisp garden salad. The addition of zesty lemon wedges cuts through the richness of the nuts for a perfectly balanced finish.

Ingredients for Roasted Halibut with Walnut Crust

  • Nonstick vegetable oil spray

  • 180ml finely chopped toasted walnuts

  • 60g panko (Japanese breadcrumbs)*

  • 1/4 cup (packed) chopped fresh Italian parsley

  • 2 tablespoons finely chopped fresh basil

  • 2 tablespoons finely chopped fresh chives

  • 170g halibut fillets (each about 1 inch thick)

  • Lemon wedges

How to make Roasted Halibut with Walnut Crust

Preheat oven to 232°C. Spray rimmed baking sheet with nonstick spray. Mix walnuts, panko, and all herbs in small bowl; sprinkle with salt and pepper. Brush each fish fillet with 1 tablespoon melted butter; sprinkle with salt and pepper. Place fish on prepared baking sheet. Sprinkle panko-herb mixture atop fish, dividing equally and pressing to adhere. Roast fish until just opaque in centre, about 8 minutes. If crisper topping desired, preheat grill and grill fish about 1 minute, watching carefully to prevent burning. Transfer fish to plates; garnish with lemon wedges.
