Pan-Seared Halibut with Lemon Beurre Blanc: Elegant, Flaky Perfection in Minutes

If you’re looking for a restaurant-quality seafood dish that feels luxurious yet is surprisingly simple to prepare at home, pan-seared halibut with lemon beurre blanc is the ultimate choice. This tender, flaky white fish gets a golden, crispy sear, then is drizzled with a silky, tangy lemon beurre blanc sauce that’s rich in buttery flavor with bright citrus notes. Perfect for date nights, special occasions, or elevating your weeknight dinner, this recipe delivers impressive results without complicated techniques.

Halibut is prized for its mild, sweet flavor and firm texture that holds up beautifully to pan-searing. Paired with the classic French beurre blanc (literally “white butter” sauce), made from reduced white wine, shallots, lemon, and cold butter emulsified into a velvety emulsion, it creates a harmonious balance of richness and acidity. This dish is naturally gluten-free, high in protein, and ready in under 30 minutes once prepped.

In this comprehensive guide, we’ll walk you through every step to achieve that perfect golden crust on the halibut while mastering a foolproof lemon beurre blanc that won’t break. From ingredient tips to common pitfalls, you’ll have all the tools to make this elegant fish dinner a standout.

The Appeal of Pan-Seared Halibut with Lemon Beurre Blanc

What makes this dish so special? The contrast: crispy exterior from high-heat searing meets buttery, melt-in-your-mouth halibut interior. The sauce adds a gourmet touch—creamy yet light, with lemon cutting through the richness for brightness. It’s versatile too—serve with asparagus, wild rice, or roasted vegetables for a complete meal.

Halibut is a premium fish, often featured in fine dining for its large flakes and subtle sweetness. Beurre blanc, a staple in French cuisine, originated as a simple reduction sauce in the Loire Valley and has become a go-to for seafood. Adding lemon makes it even more refreshing, ideal for spring and summer menus or year-round elegance.

This recipe serves 4, but scales easily for two. It’s beginner-friendly if you follow the temperature tips—halibut is done at 145°F internally for safe, moist results.

Why This Recipe Works

Unlike baked or poached halibut, pan-searing creates a flavorful crust while keeping the fish juicy. The lemon beurre blanc is stable thanks to gradual butter incorporation and optional cream for extra security. Fresh ingredients shine here: use high-quality butter and fresh lemons for the best flavor.

This method avoids overcooking—halibut can dry out quickly—so precise timing is key. The result? Restaurant-level presentation with minimal effort.

Nutritionally, halibut is lean, packed with omega-3s, protein (about 25g per serving), and low in calories (around 200-300 per fillet before sauce). The sauce adds indulgence but in moderation.

Ingredients

Gather premium, fresh items for the best outcome. Halibut should be firm and translucent.

• 4 halibut fillets (6-8 oz each, skin-on preferred for crispiness)
• 2 tbsp olive oil or high-smoke-point oil (like avocado)
• Salt and freshly ground black pepper (to taste)
• 2 tbsp unsalted butter (for basting, optional)

For the Lemon Beurre Blanc Sauce:

• 1/4 cup dry white wine (Sauvignon Blanc or Chardonnay)
• 2 tbsp fresh lemon juice
• 1 small shallot, finely minced
• 1 tbsp heavy cream (optional, for stability)
• 8 tbsp (1 stick) cold unsalted butter, cut into cubes
• 1 tsp lemon zest
• Salt and white pepper (to taste)

Optional Garnishes:

• Fresh chopped parsley or dill
• Lemon wedges

Instructions

Follow these steps for flawless results. Prep time is quick, and cooking is fast.

1. Pat the halibut fillets dry with paper towels. Season both sides generously with salt and pepper. Let sit at room temperature for 10-15 minutes.
2. Make the sauce reduction: In a small saucepan over medium heat, combine white wine, lemon juice, and minced shallot. Bring to a simmer and reduce until only 2-3 tablespoons of liquid remain (about 8-10 minutes).
3. Add cream (if using) and reduce slightly. Lower heat to very low. Begin whisking in cold butter cubes, one or two at a time, until fully emulsified and sauce thickens. Remove from heat if it gets too hot to prevent breaking.
4. Stir in lemon zest, taste, and season with salt and white pepper. Strain if desired for smoothness. Keep warm (off heat or over a double boiler).
5. Heat oil in a large, heavy skillet (cast iron or non-stick) over medium-high until shimmering hot. Place fillets skin-side down (if skin-on) and press gently to ensure contact.
6. Sear undisturbed for 3-4 minutes until skin is crispy and golden. Flip carefully, add butter if desired, and cook 2-3 minutes more, basting occasionally, until internal temperature reaches 145°F and fish flakes easily.
7. Remove from heat and let rest 2 minutes.
8. Plate the halibut, spoon warm lemon beurre blanc over the top, garnish with herbs and lemon wedges, and serve immediately.

Tips for Perfect Pan-Seared Halibut

• Dry the fish thoroughly for crispiness—moisture causes steaming instead of searing.
• Use a hot pan; test with a drop of water—it should sizzle and evaporate.
• For skin-on, start skin-down and don’t move until ready to flip.
• Avoid overcrowding; cook in batches if needed.
• If sauce breaks (looks separated), whisk in a splash of cold water or more butter off heat.
• Use fresh, cold butter for best emulsion.

Variations to Try

Add fresh herbs like dill or tarragon to the sauce for a twist. Swap lemon for Meyer lemon or add capers for briny notes. For a lighter version, reduce butter and increase zest. Serve over a bed of sautéed spinach or with roasted potatoes.

Serving Suggestions

Pair with steamed asparagus, garlic mashed potatoes, or a crisp green salad. A chilled white wine like Sauvignon Blanc complements the citrus perfectly.
