The halibut quality is non-negotiable here. Wild-caught from a reputable fishmonger ensures the flaky texture and sweet flavor this dish demands. Look for fillets that are firm, translucent, and smell like the ocean—not fishy. Whole Foods and specialty seafood markets typically carry fresh halibut, but frozen works if thawed properly overnight in the fridge.

No fresh dill? Dried dill at one-third the amount works in a pinch, though the flavor is more muted. Short on white wine? Chicken or vegetable broth with a splash of vinegar mimics the acidity. The Dijon mustard adds depth—whole grain mustard creates a rustic texture. For the lemon, both zest and juice are essential for that bright finish Ina Garten is known for.

This dish is best served immediately—halibut overcooks quickly. Leftovers? Rare, but they’ll keep for 1-2 days in the fridge. Store the uncooked fillets in the coldest part of your fridge and use within 24 hours for optimal freshness. The dill can be wrapped in damp paper towels and refrigerated for up to 1 week.

Step-by-Step Instructions for Baked Halibut

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare the Lemon-Dill Marinade

In a small bowl, whisk together 0.25 cup extra-virgin olive oil, 3 tbsp fresh lemon juice, 1 tbsp lemon zest, 0.25 cup fresh dill, 3 cloves minced garlic cloves, 1 tbsp Dijon mustard, 1 tsp kosher salt, and 0.5 tsp freshly ground black pepper. This aromatic blend infuses the fish with bright, herbaceous notes.

I always let this mixture sit for 5 minutes to allow the flavors to meld. The acidity from the lemon juice and wine will help tenderize the halibut fillets while the dill adds that signature freshness Ina Garten is known for.

Step 2: Marinate and Arrange the Halibut

Place the 1.5 lb halibut fillets in a shallow dish and pour the marinade over them, ensuring all surfaces are coated. Let it marinate for 15-20 minutes at room temperature—this is the sweet spot for flavor penetration without the acid starting to “cook” the fish.

Transfer the halibut fillets to a baking dish, arranging them in a single layer. Pour 0.25 cup dry white wine around the fish, not over it, to create a flavorful steam that will keep the fillets moist during baking. The liquid should come about halfway up the sides of the fish.

Step 3: Bake to Flaky Perfection

Preheat your oven to 400°F. Bake the halibut uncovered for 12-15 minutes, or until the fish flakes easily with a fork and reaches an internal temperature of 145°F. You’ll know it’s done when the flesh turns opaque and separates cleanly along the natural segments.

Resist the urge to overbake—halibut continues cooking slightly after removal from the oven. The key to that promised flaky texture is pulling it out just as it reaches the perfect doneness. The top should be lightly golden where the marinade has caramelized slightly.

Step 4: Finish and Serve

Drizzle the halibut with 2 tbsp melted unsalted butter immediately after removing from the oven. This adds a rich, glossy finish that complements the bright lemon-dill flavors. Garnish with the 4 slices lemon slices arranged attractively over the fillets.

Let it rest for 2-3 minutes before serving to allow the juices to redistribute. The butter will meld with the cooking liquids to create a light, flavorful sauce that pools beautifully on the plate. Serve immediately while hot for the best texture and flavor.
