Ingredients

Instructions

Prepare the Miso Glaze (24-48 hours ahead):

1. In a small saucepan over medium-low heat, combine the miso paste, mirin, sake, brown sugar, soy sauce, and grated ginger.
2. Whisk constantly until the sugar dissolves and the mixture is smooth, about 3-4 minutes. Do not let it boil.
3. Remove from heat and allow to cool completely.
4. Place the black cod fillets in a glass baking dish or resealable plastic bag. Pour the cooled miso mixture over the fish, making sure each piece is well coated.
5. Cover the dish or seal the bag and refrigerate for 24-48 hours. The longer marinating time yields more flavor and better caramelization.

Cook the Fish:

1. Remove the fish from the refrigerator 30 minutes before cooking to bring it closer to room temperature.
2. Preheat your oven to 400°F (200°C).
3. Gently wipe excess marinade from the fish with your fingers, leaving a thin coating. (The marinade is quite sweet and can burn if too thick.)
4. Heat an oven-proof skillet over medium-high heat. Add a tablespoon of neutral oil.
5. Place the fish skin-side up in the hot pan and sear for 2-3 minutes until the marinade begins to caramelize.
6. Carefully flip the fish skin-side down and transfer the skillet to the preheated oven.
7. Bake for 5-7 minutes, depending on thickness, until the fish is opaque and flakes easily with a fork. The internal temperature should reach 137°F (58°C).

Prepare the Bok Choy:

1. While the fish is in the oven, heat 2 tablespoons of neutral oil in a large skillet over medium-high heat.
2. Place the bok choy cut-side down in the hot oil and sear until golden brown, about 2-3 minutes.
3. Flip the bok choy, add the sliced garlic, and cook for 30 seconds until fragrant.
4. Add 1 tablespoon of water to the pan and cover immediately. Let steam for 2 minutes.
5. Remove the lid, drizzle with sesame oil, and season with a pinch of salt. Toss gently to coat.

To Serve:

1. Arrange the bok choy on plates or a serving platter.
2. Place the miso-glazed cod fillets on top or alongside.
3. Garnish with sliced scallions and sesame seeds.
4. Serve immediately with lemon wedges on the side.

Chef’s Tips for Perfect Miso Black Cod

Black cod has a high oil content that makes it particularly forgiving for home cooks. Unlike leaner fish that can quickly go from perfect to overcooked, black cod remains moist and tender even with a minute or two of extra cooking. That said, precision still yields the best results. Look for the moment when the flesh transforms from translucent to opaque but still maintains a subtle silkiness at the center.

If black cod (sablefish) proves difficult to find, substitute with Chilean sea bass, salmon, or even butterfish. While each alternative brings a different texture and flavor profile, the luscious miso glaze works beautifully with any rich, fatty fish. Just adjust cooking times accordingly—thinner fillets will cook more quickly than the substantial black cod portions.

The miso marinade does double duty in this recipe. Beyond infusing the fish with profound umami depth, it creates that signature caramelized exterior that makes this dish instantly recognizable. For an extra layer of flavor complexity, try using a combination of white and yellow miso, or experiment with the more robust red miso if you prefer stronger flavors. Remember that the darker the miso, the more intense the fermented flavor will be.

For the bok choy component, don’t rush the searing stage. That golden caramelization on the cut surface adds crucial flavor dimension to this relatively mild vegetable. If baby bok choy isn’t available, standard bok choy works well—simply quarter it lengthwise instead of halving. Alternatively, Chinese broccoli (gai lan) or even regular broccoli makes an excellent substitute, though you may need to adjust cooking times to ensure tenderness.

Wine Pairing Suggestion

The sweet-savory profile of miso black cod calls for a wine with enough body to stand up to its richness, yet sufficient acidity to cut through that butteriness. An off-dry Riesling from Germany or Alsace offers the perfect counterpoint, with its subtle sweetness complementing the miso’s complex flavors. If you prefer reds, opt for a light-bodied Pinot Noir from Oregon or New Zealand, whose bright fruit notes and silky tannins won’t overwhelm the delicate fish.

Make It a Complete Meal

To transform this stunning main course into a complete Japanese-inspired dinner, consider starting with a simple miso soup or a sunomono cucumber salad. For the main event, serve the miso black cod and bok choy atop a small mound of steamed short-grain rice to soak up the delectable juices. A side of quick-pickled vegetables adds a welcome brightness that balances the rich, umami-forward flavors of the fish. Finish with a light dessert like mochi ice cream or fresh fruit with a ginger-infused syrup for a meal that feels like a culinary journey through the finest restaurants in Tokyo—all from the comfort of your own dining room.
