Flaky & Tender: The Perfect Grilled Halibut with Lemon-Dill Butter
I have a deep love affair with the grill. There’s just something magical about that smoky char and the way food transforms over an open flame. But let me be honest: for years, fish was my nemesis. I’d start with a beautiful, thick fillet, full of promise, only to end up with a disaster—half stuck to the grates, half crumbled into a sad mess when I tried to flip it. It was heartbreaking.
Then came the halibut.
The very first time I successfully grilled halibut was on a bright summer evening, and it was a revelation. I used a simple lemon-dill butter that melted slowly into the flakey grilled fish, creating a gorgeous aroma that brought everyone rushing to the deck. That fish, perfectly cooked and glistening, was the moment I conquered my fear of grilling seafood. Now, I’m convinced that grilled halibut with lemon-dill butter isn’t just a recipe; it’s the ultimate summer dish. It’s elegant enough for a special occasion yet easy enough for a weeknight dinner. And I’m going to share every single trick I learned to help you achieve that elusive, flaky-tender perfection. Trust me, it’s easier than you think.

The Secret Weapon: Lemon-Dill Compound Butter 🍋🌿
Before we even touch the fish, we must make the butter. This isn’t just a sauce you drizzle; it’s a compound butter recipe that melts into the halibut as it cooks and rests, seasoning it from the inside out. This easy lemon dill sauce for fish is the difference between a good grilled fish and the perfect grilled halibut with lemon-dill butter.
✅ Ingredients for Lemon-Dill Butter
- 1/2 cup (1 stick) of unsalted butter, softened to room temperature
- 1/4 cup of fresh dill, finely chopped1
- 2 tablespoons of fresh parsley, finely chopped
- 1 lemon, zested and juiced (about 1 tablespoon of juice)
- 1 clove of garlic, minced (optional, but lovely)
- 1/2 teaspoon of sea salt
- 1/4 teaspoon of freshly cracked black pepper
🥄 Creating the Compound Butter
- Combine: In a medium bowl, combine the softened unsalted butter with the chopped dill, parsley, lemon zest, lemon juice, minced garlic, salt, and pepper.
- Mix Well: Use a rubber spatula or a fork to thoroughly mix until all the ingredients are evenly distributed. Give it a good taste here—it should be bright and fresh.
- Shape and Chill: Place the butter mixture onto a piece of plastic wrap or parchment paper. Roll it tightly into a log shape, twisting the ends to seal.
- Harden: Pop the log into the refrigerator for at least 30 minutes or until it’s firm. This makes it easy to slice and place on the fish right before serving.
Grilling Masterclass: Achieving Flaky Perfection 🎣
Halibut is a firm, lean white fish, making it one of the best choices for the grill.2 Its thickness holds up well, but you still need a few key techniques to prevent sticking and ensure the interior is tender. This is how to grill halibut without sticking—the non-negotiable steps.
✅ Ingredients for the Halibut
- 4 halibut fillets, cut into thick portions (about 6 oz each, 1-inch thick)
- 1 tablespoon of olive oil
- 1/2 teaspoon of sea salt
- 1/4 teaspoon of freshly cracked black pepper
- 8 thin slices of the chilled lemon-dill butter
🔪 Step-by-Step Grilling Instructions
- Pat the Fish Dry: This is the most crucial step! Use paper towels to thoroughly pat the halibut fillets dry. Moisture is the enemy of a good sear and is a major cause of sticking.3
- Season Simply: Brush the fillets lightly with olive oil and season generously on all sides with sea salt and black pepper. The oil helps prevent sticking, and the simple seasoning complements the rich butter we’ll add later.
- Preheat the Grill: Heat your gas or charcoal grill to a medium-high grilling temperature for fish (around 400°F or 200°C).4 Crucially, let it heat for 10 minutes minimum. A hot grill prevents sticking.
- Oil the Grates (The Real Trick): Clean your grates with a wire brush. Now, dip a wadded-up paper towel in a little oil (vegetable or canola) and, using long-handled tongs, oil the hot grates just before placing the fish down. This creates a non-stick barrier.
- Grill the First Side: Place the halibut fillets skin-side down (if present) or presentation-side down onto the well-oiled grates.5 Do NOT touch or move the fish for 4 to 5 minutes. The fish needs to develop a crust to naturally release from the grill.
- Flip Carefully: When the fish releases easily and you see nice grill marks, use a wide, thin metal spatula to gently flip the fish.
- Finish Cooking: Grill for another 4 to 5 minutes, depending on the thickness. The flakey grilled fish is done when its internal temperature reaches 145°F (63°C) and it flakes easily with a fork.6 The flesh should be opaque all the way through.
- Rest and Butter: Transfer the halibut to a plate. Immediately place two thin slices of the chilled lemon-dill butter on top of each hot fillet. Cover loosely with foil and let it rest for 3–5 minutes. This resting period allows the butter to melt perfectly into the fish and the juices to redistribute.
🌟 Pro Tips and Troubleshooting
Why did my halibut stick to the grill?
Nine times out of ten, sticking happens because:
- The grill wasn’t hot enough. The colder the grill, the more it sticks.
- The grates weren’t clean or oiled. A quick cleaning and oiling are essential every time.
- You tried to flip it too soon. Give the fish time to develop a crust—it will release on its own when ready. If you try to lift it and it resists, wait another minute.
Can I use frozen halibut?
Yes! Thaw the frozen halibut slowly overnight in the refrigerator. Before cooking, be sure to pat it extra dry with paper towels, as frozen fish tends to release more moisture when thawed.
What’s the best way to check doneness?
The best way is a meat thermometer inserted into the thickest part of the fillet. You are looking for 145°F (63°C). Visually, the flesh should be opaque and separate easily into flakes with a fork.
🍽️ Adding Value: Pairings, Sides, and Variations
🥗 Best Side Dishes for Halibut
Because halibut is such a clean, mild-flavored fish, it pairs beautifully with light, bright, and slightly crisp sides.7 The dill and lemon in the butter make these pairings absolute winners:
- Roasted Asparagus with Parmesan: The earthy bitterness of the asparagus is a lovely counterpoint to the rich butter.
- Lemon Herb Quinoa: A simple, high-protein grain that picks up the lemon-dill flavors perfectly.
- Grilled Corn and Tomato Salad: The sweetness of summer corn and the acidity of fresh tomatoes provide a refreshing balance.
- Creamy Risotto: If you want something richer, a simple, saffron-infused risotto provides an Italian luxury that complements the firmness of the fish.
🥂 Perfect Wine Pairing
The richness of the butter and the delicate texture of the flakey grilled fish call for a crisp, dry white wine that won’t overpower the fish.
- Sauvignon Blanc: This is a classic choice. Its high acidity and notes of grass and citrus perfectly echo the lemon and dill in the butter.
- Pinot Grigio: A lighter, more mineral-driven option that offers a clean, palate-cleansing finish.8
- Unoaked Chardonnay: Choose one from a cooler climate. It has slightly more body than Pinot Grigio without the heavy, buttery feel that would clash with the compound butter.
💡 Variations on Healthy Halibut Recipes
Want to switch up the flavor profile? Halibut is wonderfully versatile!
- Spicy Caribbean Rub: Instead of the lemon-dill butter, coat the fish in a dry rub made from smoked paprika, a little brown sugar, thyme, and a pinch of cayenne. Finish with a squeeze of fresh lime juice after grilling.
- Mediterranean Style: Grill the halibut and then serve it topped with a warm relish of diced Kalamata olives, sun-dried tomatoes, capers, and a drizzle of good quality extra virgin olive oil.
- Asian Glaze: Brush the fish with a glaze made from soy sauce, ginger, garlic, and a touch of honey during the last few minutes of grilling. This transforms the dish into an umami-rich experience, still fitting the criteria for healthy halibut recipes.

Reheating
To gently reheat, place the fish on a baking sheet, cover it tightly with foil, and warm it in a preheated oven at 275°F (135°C) for about 10–15 minutes until just warm. Avoid the microwave, which can make the fish rubbery.
