Ingredients You’ll Need
Tip: You’ll find the full list of ingredients and measurements in the recipe card below.
- ⅓ cup mayonnaise
- 1 shallot, finely diced
- 2 tablespoons lemon juice
- 1 tablespoon parsley, finely chopped
- 2 tablespoons chives, finely chopped
- 1 teaspoon Dijon mustard
- Salt, to taste
- Black pepper, to taste
- 4 halibut fillets
Let’s Get Started
-
Preheat your oven to 400°F (200°C). Lightly grease a baking dish or line it with parchment paper to prevent sticking and make cleanup easier.
-
Pat the halibut fillets dry with paper towels. Removing excess moisture helps the topping adhere better and ensures the fish bakes evenly.
-
Arrange the halibut fillets in the prepared baking dish in a single layer, leaving a little space between each piece.
-
In a small bowl, combine the mayonnaise, finely diced shallot, lemon juice, chopped parsley, chopped chives, and Dijon mustard. Stir until the mixture becomes smooth and evenly blended.
-
Season the mixture with salt and freshly ground black pepper to taste. The lemon and herbs should create a bright, balanced flavor.
-
Spoon the herb mayonnaise mixture evenly over each halibut fillet, spreading it gently to cover the tops.
-
Place the baking dish in the oven and bake for 12–15 minutes. The fish should turn opaque and flake easily with a fork when it’s fully cooked. Cooking time may vary depending on the thickness of the fillets.
-
Remove from the oven and allow the fish to rest for 2 minutes before serving. This helps the juices settle and keeps the fillets tender.
Servings and Pairing
This recipe serves four people. Serve the halibut with roasted vegetables, steamed asparagus, lemon rice, or a light green salad. For a heartier meal, pair it with roasted potatoes or couscous.
Variations
-
Add lemon zest to the topping for extra citrus brightness.
-
Sprinkle a little grated Parmesan on top before baking for a golden finish.
-
Swap parsley for fresh dill for a more classic seafood flavor.
-
Add a pinch of paprika or smoked paprika for subtle warmth.
-
Use Greek yogurt in place of half the mayonnaise for a lighter option.
Storage Tips
Store leftover halibut in an airtight container in the refrigerator for up to 2 days.
Reheat gently in a 300°F oven for about 8–10 minutes until just warmed through. Avoid microwaving if possible, as fish can dry out quickly.
This dish is best enjoyed fresh, but leftovers can be flaked and added to salads or wraps.
FAQs
Can I use frozen halibut?
Yes. Thaw the fish completely in the refrigerator and pat it dry before baking.
How do I know when halibut is cooked?
The fish should turn opaque and flake easily with a fork. An internal temperature of 145°F indicates it’s fully cooked.
Can I substitute another fish?
Yes. Cod, haddock, or sea bass work well with the same cooking method.
Can I prepare the topping ahead of time?
Absolutely. The herb mayonnaise mixture can be prepared up to one day ahead and stored in the refrigerator.
Final Thoughts
Easy Baked Halibut is a perfect reminder that simple ingredients can create an elegant meal. The creamy lemon herb topping keeps the fish moist while adding bright, fresh flavor in every bite.
It’s the kind of recipe that’s easy enough for a weeknight yet special enough to serve when guests come over.
