Jamie Oliver’s Oven Roasted Halibut is a quick and healthy recipe that showcases the meaty, flaky texture of halibut. Roasting the fish in the oven ensures even cooking and helps lock in moisture, resulting in tender, flavorful fillets. The use of fresh herbs, lemon, and a drizzle of olive oil adds brightness and complements the natural flavor of the halibut without overpowering it.
Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper or lightly grease it with olive oil to prevent the fish from sticking.
Season the halibut fillets generously with salt and pepper on both sides. Place the fillets on the prepared baking tray. Drizzle each fillet with olive oil, ensuring they are lightly coated.
Scatter the sliced garlic and fresh herbs (thyme or rosemary) around the fish. Lay a few lemon slices on top of each halibut fillet to infuse them with a fresh, zesty flavor as they cook. If using butter, add a small knob on top of each fillet for extra richness.
Place the tray in the preheated oven and roast the halibut for 10-12 minutes, depending on the thickness of the fillets. The fish should be opaque and flaky when tested with a fork, but still moist. If desired, turn on the grill for the last 2 minutes to give the fish a golden, crispy finish.
Once roasted, remove the halibut from the oven and let it rest for a minute or two. Serve the fish with the roasted lemon slices and garlic, garnished with some fresh herbs for added flavor and presentation. A light drizzle of olive oil or a squeeze of fresh lemon juice can also elevate the dish.
