Pan-Roasted Halibut with Beurre Blanc & Asparagus

Pan-roasted halibut with beurre blanc is the seafood main course that belongs on every elegant group dinner menu — pristine white flesh, perfectly seared to a golden crust, served on a classic French butter sauce that is bright with white wine and shallots, alongside roasted asparagus spears. It is sophisticated, seasonal, and genuinely spectacular.

Halibut is the most elegant flatfish — its dense, sweet, snow-white flesh holds up beautifully to high-heat searing in a way that more delicate fish cannot. Beurre blanc — "white butter" — is one of the great classic French butter sauces, and while its reputation for difficulty is somewhat deserved, the technique is learnable and the result is incomparable.

Ingredients (serves 10–12): - 10–12 halibut fillets (about 6 oz each), skin removed or on - 2 tablespoons neutral oil - 2 tablespoons unsalted butter - Salt and white pepper - 1¾ lbs asparagus, trimmed and roasted (see our Roasted Asparagus with Lemon Zest recipe)

Beurre Blanc: - 4 shallots, very finely minced - ⅞ cup dry white wine (Sancerre or Chablis ideal) - ½ cup white wine vinegar - 3 tablespoons heavy cream (helps stabilize) - 10.6 oz cold unsalted butter, cut into small cubes - Salt and white pepper - Fresh chervil or chives for garnish - Lemon juice to finish

Beurre Blanc Instructions: Combine shallots, white wine, and vinegar in a small saucepan. Reduce over medium heat until approximately 3 tablespoons of liquid remain — the shallots should be very soft and the liquid syrupy. Add cream, reduce briefly. Over the lowest possible heat, whisk in cold butter cubes one or two at a time, whisking constantly and adding each piece only when the previous has been fully incorporated. The sauce should be smooth, creamy, and opaque. Season with salt, pepper, and a few drops of lemon juice. Keep warm in a bain-marie — do not let it boil or it will break.

Halibut Instructions: Pat fillets completely dry. Season generously. Heat oil in a large, heavy pan until just smoking. Place halibut presentation-side down. Cook undisturbed 3–4 minutes until a golden crust forms. Flip gently, add butter, and baste for 1–2 minutes until the fish is just cooked through (it should be opaque throughout but still slightly translucent in the very center when you check with the tip of a knife — it will finish cooking from residual heat).

Plating: Rest halibut briefly. Place 3–4 asparagus spears on a warm plate. Set halibut beside or on top. Spoon beurre blanc generously over and around the fish. Garnish with chervil or chives and a twist of lemon zest.

Pro Tips: The single greatest risk with halibut is overcooking — it goes from silky to dry quickly. Remove from heat when it still looks very slightly underdone. The beurre blanc is the most technically demanding element; prepare it up to 45 minutes ahead and hold it warm in a bain-marie, whisking occasionally.
