A rich and savory halibut dish topped with roasted garlic, creamy parmesan mayo, and broiled until golden — perfect for an elegant weeknight dinner or impressive seafood centerpiece.

Ingredients

Scale
  • 1 head of garlic
  • ½ tablespoon olive oil
  • 1 tablespoon unsalted butter
  • 1 pound halibut fillets, skinless, divided into 4 portions
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste
  • ½ cup mayonnaise
  • ½ cup parmesan cheese, grated

Instructions

  1. Preheat the oven to 375°F (190°C). Cut the top off a head of garlic, brush off the outer paper skin, and leave the cloves intact. Place on foil, drizzle with olive oil, wrap tightly, and roast for 45 minutes until soft. Set aside 6 cloves for the recipe and save the rest for later use.
  2. Increase oven temperature to 425°F (220°C). Heat butter in an oven-safe pan over low heat. Season halibut fillets with salt and pepper. Once butter is melted, place fillets in the pan and transfer to oven. Roast for 10 minutes until opaque and just cooked through.
  3. Blend 6 roasted garlic cloves with mayonnaise and grated parmesan until smooth and creamy.
  4. Remove the fish from the oven and generously spread the garlic-parmesan mixture on top. Set oven to high broil and return the pan for about 4 minutes, until the topping is golden brown.
  5. Carefully remove the pan and let the halibut sit for a minute. Serve hot with your favorite vegetable or salad sides.

Notes

  • Use freshly grated parmesan for best flavor and texture.
  • Leftover roasted garlic can be stored in the fridge for up to a week.
  • Be careful not to overcook the halibut to maintain its tender texture.
  • This topping works well on other white fish like cod or haddock.
