This elegant baked halibut features tender, flaky fish fillets infused with aromatic fresh herbs including parsley, dill, and chives, combined with melted butter and garlic. The fillets are seasoned simply with sea salt, pepper, and optional paprika, then topped with fresh lemon slices before baking. The entire dish comes together in just 30 minutes, making it perfect for weeknight dinners or entertaining guests. The herb-butter mixture keeps the fish moist while imparting rich, natural flavors. Serve immediately with the pan juices spooned over for maximum flavor and presentation.

The day my neighbor gifted me fresh-caught halibut changed everything about how I approach seafood. Standing in my kitchen, I remember feeling intimidated by these perfect white fillets that deserved more than my usual lemon-pepper treatment. The solution came when I glanced at my overflowing herb garden outside the kitchen window – those vibrant greens paired with melted butter would let the delicate fish truly shine.

Last summer, I served this halibut at an impromptu dinner when friends stopped by unexpectedly. The kitchen windows were open, and as the herb-infused butter aroma filled the air, conversations paused momentarily. My normally seafood-hesitant friend Mark asked for seconds, then quietly requested the recipe before leaving that evening.

Ingredients

  • Halibut fillets: Look for firm, translucent fillets without any fishy smell – I've learned fresh truly matters for a dish this simple.
  • Fresh herbs: The combination of parsley, dill and chives creates this beautiful layered flavor that dried herbs simply cannot replicate.
  • Unsalted butter: Using unsalted lets you control the seasoning perfectly, though I once used salted in a pinch and just reduced the added salt.
  • Lemon slices: They not only flavor the fish but create a natural steaming effect that keeps everything incredibly tender.

Instructions

Prep your fish:
Start by patting those beautiful fillets completely dry with paper towels. This might seem fussy, but it ensures the butter mixture adheres properly and helps develop that lovely golden exterior.
Make your herb butter:
In a small bowl, stir together melted butter, olive oil, and all those fragrant chopped herbs until well combined. The aroma alone will make your kitchen smell incredible.
Season generously:
Brush the herb butter mixture over each fillet, making sure to coat all sides. Then sprinkle with salt, pepper and that optional paprika which adds both color and a subtle warmth.
Arrange your lemons:
Place thin lemon slices on and around the fish – they'll infuse everything with bright citrus notes while cooking. The oils from the rinds work magic here.
Bake to perfection:
Slide the baking dish into your preheated oven and let it work its magic for 15-20 minutes. You'll know its done when the fish flakes easily with a fork but still looks moist.
Serve immediately:
Don't forget to spoon those aromatic pan juices over each serving. Those buttery drippings contain concentrated flavors that would be a shame to leave behind.

My daughter, who declared herself a vegetarian at fourteen, made an exception for this halibut dish during her senior year of high school. We sat at the kitchen island, both surprised by her change of heart, and she admitted between bites that sometimes good food transcends rigid rules. That night, this simple recipe became our bridge back to shared meals.

Suitable Substitutions

Through several iterations of this recipe, I've discovered that cod and haddock work beautifully as alternatives when halibut prices soar or availability is limited. The texture differs slightly – cod being a bit flakier and haddock somewhat firmer – but the herb butter treatment elevates whatever fish you choose.

Perfect Pairings

After countless servings, I've found that sides with contrasting textures really complement this dish best. Crisp-tender asparagus spears roasted alongside the fish absorb some of those wonderful butter drippings, while fluffy roasted potatoes provide the heartiness that turns this into a complete meal.

Make-Ahead Options

While the fish itself is best prepared just before serving, you can absolutely mix the herb butter up to three days ahead and store it in the refrigerator. Just bring it back to room temperature before using.

  • Prep all herbs and garlic the morning of cooking to save time in the evening rush.
  • Set out your baking dish and measuring tools earlier in the day to streamline the cooking process.
  • If serving company, slice lemons and arrange them decoratively on a plate in the refrigerator until needed.
