Roasted Garlic and Parmesan Baked Halibut

This roasted garlic and Parmesan baked halibut is a sophisticated yet simple way to enjoy white fish. By roasting the garlic first, you create a mellow, sweet base that perfectly complements the salty tang of the Parmesan crust. The halibut remains beautifully moist under its golden topping, offering a refined balance of textures and flavours that feels far more indulgent than its healthy profile suggests.

As a high-protein dish, this recipe is ideal for those seeking a nutritious but flavourful evening meal. The halibut provides a lean source of protein, while the rich crust ensures every bite is deeply satisfying. Serve these fillets alongside steamed seasonal greens or a crisp garden salad for a light, elegant dinner that is quick enough for a weeknight but impressive enough for guests.

Ingredients for Roasted Garlic and Parmesan Baked Halibut

  • 1 garlic head

  • 1/2 tablespoons olive oil

  • 1 tablespoon unsalted butter

  • 450g halibut, skin removed, in 4 even fillets

  • Kosher salt, as needed

  • Freshly ground black pepper, as needed

  • 80g mayonnaise

  • 80g grated Parmesan

Preheat the oven to 375˚F.

Cut off the top of the head of garlic and brush off some of the outer paper skin, leaving just the individually wrapped cloves. On a piece of foil, pour the olive oil over the garlic, then wrap the foil around it and place it in the oven for 45 minutes, until it’s completely soft. For the recipe, you’ll only need six cloves from the head, but it’s worth making a whole head to keep the rest for spreading on crusty bread or adding to salads.

Raise the oven temperature to 425˚F.

Heat the butter in an oven-proof pan over low heat. Sprinkle both sides of the fish with salt and pepper. When the butter is melted, add the halibut and put it into the oven for 10 minutes. The fish should be just cooked and opaque throughout.

While the halibut cooks, blend or food process together six cloves of garlic, the mayonnaise, and parmesan. When the halibut is done, pull it out and generously smear the mayonnaise mixture on the top. Switch the oven to a high grill and return the pan to the still-hot oven for 4 minutes under the grill, until the top is almost entirely golden brown.

Remove and serve immediately.
