- 4 halibut steaks, approx. 6 oz (170 g) each - 2 tbsp (30 ml) olive oil - 1 tsp (5 g) kosher salt - 1/2 tsp (1 g) freshly ground black pepper - 2 tbsp (28 g) unsalted butter - 1 small shallot, finely minced - 2 tbsp (30 ml) dry white wine - 1 lemon, zested and juiced - 4 tbsp (56 g) cold unsalted butter, cubed - 2 tbsp (30 ml) chopped fresh parsley - Lemon wedges, for serving
1. Pat the halibut steaks dry and season both sides with kosher salt and black pepper. 2. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. 3. Add the halibut steaks and sear without moving 3–4 minutes until golden; flip and sear 3–4 minutes more until opaque and cooked through (internal temp ~130–135°F / 55–57°C). 4. Transfer fish to a warm plate and tent loosely with foil. 5. Reduce heat to medium, add 2 tbsp butter to the skillet and melt; add minced shallot and sauté 1–2 minutes until softened. 6. Deglaze with 2 tbsp white wine and simmer 1 minute to reduce slightly. 7. Stir in lemon juice and zest, then remove pan from heat and whisk in the 4 tbsp cold butter cubes a few pieces at a time to emulsify into a glossy sauce. 8. Spoon sauce over halibut, sprinkle with chopped parsley, and serve with lemon wedges.
