Ingredients
For the Halibut
Halibut fillets: 4 portions (about 1⅓ lbs total)
Olive oil: 1 tablespoon
Salt: ½ teaspoon
Black pepper: ¼ teaspoon
For the Lemon Garlic Mayo Crust
Mayonnaise: ⅓ cup
Garlic: 2 cloves, finely minced
Fresh lemon juice: 1 tablespoon
Lemon zest: 1 teaspoon
Grated Parmesan cheese: ¼ cup
Panko breadcrumbs: 2 tablespoons
Fresh parsley: 1 tablespoon, chopped
Paprika: A pinch (for color)
Instructions
Preheat the oven
Preheat your oven to 400°F (200°C). Lightly grease a baking dish or line it with parchment paper to prevent sticking.
Prepare the halibut fillets
Pat the halibut fillets dry with paper towels. This helps the seasoning stick and ensures better browning.
Season the fish
Place the fillets in the baking dish and drizzle them with olive oil. Sprinkle evenly with salt and black pepper.
Make the lemon garlic mayo mixture
In a small bowl, combine mayonnaise, minced garlic, lemon juice, lemon zest, Parmesan cheese, panko breadcrumbs, parsley, and paprika.
Mix thoroughly
Stir until all ingredients are well combined and the mixture forms a thick, creamy topping.
Top the halibut
Spoon the lemon garlic mayo mixture evenly over each halibut fillet, spreading it gently to cover the top.
Bake the fish
Place the baking dish in the preheated oven and bake for 12–15 minutes, depending on the thickness of the fillets.
Check doneness
The fish should be opaque and flake easily with a fork, and the crust should be lightly golden.
Optional broil for crispiness
For a crispier crust, broil the fish for 1–2 minutes at the end of cooking.
Serve immediately
Remove from the oven, garnish with extra parsley or lemon wedges if desired, and serve warm.
Tips
Choose fresh halibut for the best flavor and texture.
Pat the fish dry before seasoning to help the crust adhere better.
Use fresh lemon zest instead of bottled juice for brighter flavor.
Don’t overbake the fish; halibut cooks quickly and can become dry.
Use high-quality mayonnaise for a richer taste.
Grate Parmesan finely so it melts smoothly into the topping.
Broil briefly at the end to achieve a golden crust.
Let fish rest 2 minutes after baking for better texture.
Use a thermometer; fish is done at 145°F (63°C).
Serve with a squeeze of fresh lemon to brighten the flavors.
