Miso Chilean Sea Bass Recipe Nobu: Signature Black Cod With Sweet-Savory Glaze

This recipe brings Nobu’s legendary miso-glazed black cod to your home kitchen with professional precision. The signature dish combines tender Chilean sea bass with a sweet-savory white miso marinade that caramelizes beautifully under the broiler.

I’ve adapted the restaurant technique for home cooks, maintaining the 48-hour marinating process that’s essential for developing those complex flavors. The key is patience—rushing this step would compromise the dish’s iconic taste.

The result is buttery fish with a glossy, slightly charred glaze that balances salty, sweet, and umami notes perfectly. Each bite delivers the melt-in-your-mouth texture that made Nobu’s version world-famous.

Serve this as a centerpiece for special occasions, paired simply with steamed rice and seasonal vegetables to let the fish shine.

Ingredients for Miso Chilean Sea Bass Recipe Nobu

Pantry staples meet premium fish. Simple ingredients, restaurant-level results.

The sea bass is non-negotiable here. Chilean sea bass (also called Patagonian toothfish) has the buttery texture this dish demands. Look for skin-on, center-cut fillets at high-end grocery stores like Whole Foods or Specialty seafood markets—avoid anything that smells fishy or has dull flesh. The miso paste should be white, not red or awase. Miso Master or South River brands are solid choices.

No mirin? Substitute with 2 tbsp rice vinegar plus 1 tsp sugar. Out of sake? Dry sherry works in a pinch. The sugar can be swapped for honey (but don’t overdo it). For the soy sauce, tamari is a gluten-free alternative. If you can’t find fresh ginger, ground ginger at one-third the amount works, but fresh is better. The garnishes are flexible—skip the sesame if you don’t have it.

Marinate the fish in the fridge for the full 48 hours—this isn’t negotiable. Cooked sea bass keeps for about 2 days in the fridge, but it’s best fresh. The marinade can be made ahead and stored in the fridge for up to 1 week. Leftovers? Reheat gently in a low oven to avoid drying out the fish.

Step-by-Step Instructions for Miso Chilean Sea Bass

This is the method that delivers Nobu’s legendary sweet-savory glaze with tender, flaky fish.

Step 1: Marinate the Chilean Sea Bass Fillets

In a bowl, combine the 0.5 cup White Miso Paste, 0.25 cup Mirin, 0.25 cup Sake, 2 tbsp Sugar, and 2 tbsp Soy Sauce. Whisk until the sugar dissolves completely and the mixture becomes smooth and glossy.

Add the 1.5 lb Chilean Sea Bass Fillets to the marinade, ensuring they’re fully coated. I like to massage the marinade into the flesh for maximum flavor penetration. Cover and refrigerate for 24-48 hours—this extended marinating time is crucial for achieving that deep umami flavor.

Step 2: Prepare the Aromatics and Garnishes

Just before cooking, finely grate the 1 tbsp Fresh Ginger and mince the 2 cloves Garlic Cloves to a paste-like consistency. These will add a bright, sharp contrast to the rich miso glaze.

Thinly slice the 3 whole Green Onions and toast the 1 tsp Sesame Seeds in a dry pan until golden and fragrant. Set both aside for garnishing. This prep work ensures everything is ready when the fish comes out of the oven.

Step 3: Sear and Finish the Fillets

Preheat your oven to 400°F. Remove the fillets from the marinade, wiping off excess (reserve the marinade for the glaze). Heat the 1 tbsp Vegetable Oil in an oven-safe skillet over medium-high heat until shimmering.

Sear the fillets skin-side down for 2-3 minutes until the skin is crisp and golden. Flip carefully and transfer the skillet to the oven. Roast for 8-10 minutes until the fish flakes easily with a fork and reaches an internal temperature of 140°F.

Step 4: Create the Glaze and Serve

While the fish roasts, pour the reserved marinade into a small saucepan. Simmer over medium heat for 5-7 minutes, stirring constantly, until it thickens into a glossy glaze. Be careful not to let it burn—the sugars in the marinade can caramelize quickly.

Spoon the glaze over the cooked fillets and garnish with the sliced green onions and toasted sesame seeds. Serve immediately over 2 cups Steamed Rice to soak up the incredible sauce. The contrast of the crispy skin, tender fish, and sweet-savory glaze is what makes this dish unforgettable.
