Miso-Butter Broiled Black Cod with Sesame Spinach & Pickled Ginger

SeasonedPasta4927

This elegant Japanese-inspired dish spotlights black cod, renowned for its buttery texture, luxuriating in a sweet-savory miso-butter marinade. Broiling caramelizes the miso and butter, creating a glossy, umami-rich crust while keeping the fish velvety inside. Sautéed spinach tossed with toasted sesame oil and seeds delivers a nutty, earthy counterpoint, while pickled ginger and a wedge of lime or yuzu add brightness and zip. Finished with fresh scallion, the plate is visually vibrant and packed with layered flavor—perfect for a refined solo dinner or special occasion. Every bite is rich, balanced, and deeply satisfying.

Ingredients

Instructions

In a small bowl, whisk together white miso paste, softened butter, mirin, sake, and sugar until smooth.
Pat black cod fillet dry. Place fillet in a shallow dish or resealable bag. Slather with miso-butter marinade, coating all sides. Marinate at room temperature for 20 minutes (or refrigerate up to 24 hours; bring to room temp before cooking).
Preheat broiler to high. Line a small baking sheet with foil and lightly oil it. Remove excess marinade from cod, leaving a light coating. Place cod skin-side down on the sheet.
Broil cod on top rack, 4–6 inches from heat, until deeply caramelized and just cooked through, 7–8 minutes. (If edges brown too quickly, tent with foil.) Fish should flake easily but remain velvety within.
Meanwhile, heat toasted sesame oil in a medium nonstick skillet over medium-high heat. Add spinach and a pinch of salt; sauté just until wilted, 60–90 seconds. Transfer to plate, sprinkle with toasted sesame seeds.
To serve, nestle cod atop or beside sautéed spinach. Garnish with scallion, pickled ginger, and a squeeze of lime or yuzu. Serve immediately.
