Ingredients
  • ½ cup blanched hazelnuts
  • 1 large bunch fresh tarragon
  • 1 3-3½-pound skinless halibut fillet (halved lengthwise if very wide)
  • 4 tablespoons olive oil, divided
  • Kosher salt, freshly ground pepper
  • ½ cup (1 stick) unsalted butter
  • ¼ cup fresh lemon juice
  • Lemon halves
Instructions
  1. Preheat oven to 350°. Spread hazelnuts in a single layer on a rimmed baking sheet and toast, stirring occasionally, until golden, 8-10 minutes. Note: If using skin-on hazelnuts, rub them inside a clean kitchen towel after they've been toasted—the skins will slip right off.
  2. Coarsely chop; set aside.
  3. Reduce oven temperature to 300°. Scatter tarragon sprigs on a large rimmed baking sheet. Place halibut on top, drizzle with 2 tablespoons oil, and season with salt and pepper.
  4. Roast until halibut is just opaque in the center, 20-30 minutes, depending on thickness of fish.
  5. Meanwhile, melt butter in a small saucepan over medium-high heat. Cook, stirring often, until butter foams, then browns (don't let it burn), about 5 minutes.
  6. Remove from heat; let brown butter cool slightly.
  7. Stir in lemon juice, hazelnuts, and remaining 2 tablespoons oil; season with salt and pepper.
  8. Serve fish with hazelnut brown butter sauce and lemon halves.
