What You’ll Need
Gathering your ingredients is the first step to culinary success. This recipe calls for fresh, simple items that come together to create a symphony of flavors.
- ✦ 2 (6-ounce) halibut fillets, skin off
- ✦ 2 tablespoons unsalted butter, melted
- ✦ 1 tablespoon fresh lemon juice
- ✦ 1 clove garlic, minced
- ✦ 1 teaspoon fresh parsley, chopped
- ✦ ½ teaspoon dried dill
- ✦ ¼ teaspoon sea salt
- ✦ ⅛ teaspoon black pepper
- ✦ Lemon wedges for serving

Preparation Instructions
Achieving perfectly cooked Baked Halibut is surprisingly simple with these step-by-step instructions. This easy white fish recipe is designed for quick success and maximum flavor.
1. Preheat Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. Prepare Halibut: Pat the halibut fillets dry thoroughly with paper towels. This helps ensure a better texture and allows the seasoning to adhere well. Place them on the prepared baking sheet, leaving some space between each fillet.
3. Make Butter Sauce: In a small bowl, whisk together the melted unsalted butter, fresh lemon juice, minced garlic, chopped fresh parsley, dried dill, sea salt, and black pepper until well combined.
4. Season Fish: Generously brush the butter mixture over the top and sides of each halibut fillet. Ensure an even coating for maximum flavor.
5. Bake: Bake for 10-15 minutes, or until the fish is opaque throughout and flakes easily with a fork. Cooking time will vary based on the thickness of your fillets. Avoid overcooking, as halibut can dry out quickly.
6. Serve: Remove from the oven and serve immediately with extra lemon wedges for a bright finish and your favorite side dishes.

Fun Twists & Serving Ideas
- ✦ Spicy Kick: Add a pinch of red pepper flakes to the butter mixture for a subtle heat.
- ✦ Herb Garden: Experiment with other fresh herbs like chives, tarragon, or thyme instead of dill and parsley.
- ✦ Parmesan Crust: Mix 2 tablespoons of grated Parmesan cheese into the butter mixture before brushing for a savory crust.
- ✦ Sheet Pan Dinner: Add quick-cooking vegetables like asparagus spears or cherry tomatoes to the baking sheet alongside the halibut during the last 10 minutes of cooking. Toss them lightly with olive oil, salt, and pepper.
- ✦ Serving Suggestions: Pair with roasted asparagus, a fresh green salad, quinoa, or a simple rice pilaf.

FAQ
Q: Can I use frozen halibut fillets?
A: Yes, absolutely! Just be sure to thaw them completely in the refrigerator overnight or under cold running water, then pat them very dry before proceeding with the recipe.
Q: How do I know when the halibut is cooked through?
A: Halibut is cooked when it becomes opaque throughout and flakes easily with a fork. The internal temperature should reach 145°F (63°C).
Q: Can I prepare the butter mixture ahead of time?
A: Yes, you can mix the butter, lemon juice, garlic, and herbs a few hours in advance and store it in the refrigerator. Gently rewarm it if needed before brushing onto the fish.
Q: What if I don’t have fresh herbs?
A: You can use dried herbs, but reduce the quantity as dried herbs are more potent. For this recipe, use about ½ teaspoon of dried parsley and ¼ teaspoon of dried dill.
Q: What other white fish can I use for this recipe?
A: This recipe works wonderfully with other firm white fish like cod, haddock, or snapper. Adjust baking time slightly based on thickness.

Recipe Note
For the most tender and flavorful halibut, ensure you don’t overcook it. Fish continues to cook slightly after being removed from the oven, so it’s better to undercook it by a minute than to overcook it.
