Flaky halibut fillets are topped with a golden California walnut panko crust that adds richness, texture, and subtle nuttiness, then baked until just tender. The fish sits over a peppery walnut arugula pesto that provides freshness, color, and savory depth to the plate. A spoonful of lightly dressed herbed tomatoes adds brightness and acidity, balancing the richness of the walnuts and butter. Together, the walnut crust, vibrant pesto, and fresh tomatoes create a refined yet approachable seafood dish suitable for foodservice, retail, or home kitchens.
