Fresh and simple ingredients are all you need for this delicious baked halibut.
  • Halibut Fillets: Look for fresh or frozen-thawed halibut fillets that are about 1 to 1.5 inches thick. This thickness is key to a juicy final product. If using frozen, make sure they are fully thawed.
  • Unsalted Butter: Melted butter adds richness and is essential for keeping the fish moist. You can substitute with a good quality olive oil.
  • Garlic: Freshly minced garlic provides the best flavor. Avoid the jarred kind if you can.
  • Lemon: We use both the zest and the juice for a bright, fresh citrus flavor that cuts through the richness of the butter.
  • Fresh Parsley: Chopped fresh parsley adds a pop of color and freshness at the end. Dill is also a wonderful substitute.
  • Salt & Pepper: To season the fish and enhance all the flavors.

How to Make The Best Baked Halibut Recipe

Making delicious oven-baked halibut is as easy as 1-2-3. Follow these simple steps for a perfect result.

1. Preparation

First, preheat your oven to 400°F (200°C). Pat the halibut fillets completely dry with a paper towel. This step is crucial! A dry surface allows the fish to brown slightly and helps the seasoning adhere properly. Arrange the fillets in a single layer in a baking dish lined with parchment paper for easy cleanup.

2. Make the Lemon Garlic Butter Sauce

In a small bowl, whisk together the melted butter, minced garlic, lemon zest, and lemon juice. This simple sauce is the secret to flavor and moisture.

3. Season and Bake

Brush the lemon garlic butter sauce generously over all sides of the halibut fillets. Season them well with salt and freshly ground black pepper. Place the baking dish in the preheated oven and bake for 12-15 minutes. The exact time will depend on the thickness of your fillets.

Pro Tips for Perfectly Moist & Flaky Halibut

  • Don’t Overcook: This is the most important rule. Halibut is a lean fish and will dry out quickly if overcooked. The fish is done when it reaches an internal temperature of 130-135°F (54-57°C) and flakes easily with a fork. It will continue to cook slightly from residual heat after you remove it from the oven.
  • Thickness Matters: The “10-minute rule” is a great guideline for cooking fish: bake for 10 minutes per inch of thickness. For this recipe at 400°F, we find a slightly faster cook time works best.
  • Use Enough Fat: The butter or olive oil is not just for flavor; it creates a protective barrier that locks in moisture. Be generous!
