Baked Halibut Garlic Butter

The first time I made this halibut, my kitchen filled with such an incredible garlic butter aroma that my neighbor actually knocked on the door to ask what I was cooking.

I served this at a small dinner party last spring, and everyone went quiet for that first bite except for these little appreciative murmurs.

Ingredients

• Halibut fillets: This fish is worth every penny because its firm meaty texture holds up beautifully to baking without falling apart
• Unsalted butter: Melting this with olive oil creates a rich base that carries all the garlic flavor perfectly
• Extra virgin olive oil: The oil prevents the butter from burning while adding its own fruity complexity
• Fresh garlic: Four cloves might seem like a lot but trust me, the roasting mellows it into something sweet and aromatic
• Lemon juice and zest: The acid cuts through the rich butter while the zest adds this bright floral note
• Fresh parsley: It adds freshness and color that makes the whole dish pop visually

Instructions

Get your oven ready:

Preheat to 400F and line your baking dish with parchment paper for effortless cleanup later

Arrange the fish:

Lay the halibut fillets in a single layer so they cook evenly and get nicely coated with that garlic butter

Make the magic sauce:

Whisk together the melted butter, olive oil, minced garlic, lemon juice, zest, parsley, salt, and pepper until fragrant

Coat the fish:

Spoon that gorgeous garlic butter mixture evenly over each fillet, making sure none of that flavor goes to waste

Bake to perfection:

Let it cook for 15 to 20 minutes until the fish turns opaque and flakes easily with a fork

Finish with flourish:

Garnish with fresh lemon wedges and extra parsley if you want it to look as good as it tastes

Save

This recipe has become my go to when I want to serve something that feels special but does not require me to stress in the kitchen.

Making It Your Own

I have learned that adding a pinch of red pepper flakes to the butter sauce gives this gentle warmth that balances the richness beautifully.

Perfect Pairings

Roasted asparagus with a squeeze of fresh lemon or some crusty gluten free bread to soak up that extra sauce never fails to complete the meal.

Timing Everything Right

Getting the fish into the oven at exactly the right moment so it finishes when your sides are ready is worth planning ahead.

• Prep your vegetables before starting the fish
• Have everything measured out before you turn on the oven
• Set the table while the halibut bakes so you can serve it immediately

Save

There is something deeply satisfying about serving a dish this elegant that required such minimal effort to pull together.
