Ever had that first bite of Miso Glazed Black Cod where the fish just melts in your mouth like butter? That sweet-savory glaze caramelizing on the edges while the fish remains perfectly tender inside is nothing short of magical. This iconic Japanese dish might seem like restaurant-exclusive territory, but I’m here to let you in on a secret: it’s surprisingly simple to create this luxurious experience right in your own kitchen.
Why This Recipe is Awesome
What makes Miso Glazed Black Cod truly special is its perfect balance of flavors and textures.
The buttery texture of black cod (also called sablefish) pairs beautifully with the complex umami of miso paste, sweetened with mirin and sugar. This is the same dish that Chef Nobu Matsuhisa made famous worldwide, but our home version requires minimal ingredients and surprisingly little active cooking time. The magic happens in the marinade – a few minutes of prep work rewards you with an elegant dish that will genuinely impress anyone lucky enough to share your table.
The technique you’ll learn here – marinating fish in a miso mixture – can be applied to other seafood and even chicken, expanding your culinary repertoire with just one recipe.
Equipment needed: Mixing bowl, whisk, baking sheet, parchment paper, shallow dish for marinating
Miso Glazed Black Cod
Ingredients
- 4 black cod fillets about 6 ounces each – skin on
- 1/2 cup white miso paste shiro miso
- 1/4 cup mirin Japanese sweet rice wine
- 1/4 cup sake substitute: dry white wine
- 3 tablespoons granulated sugar
- 1 tablespoon soy sauce
- 1 tablespoon grated fresh ginger optional
- Sliced scallions and sesame seeds for garnish
Instructions
- Make the miso marinade: In a mixing bowl, whisk together the miso paste, mirin, sake, sugar, soy sauce, and grated ginger (if using) until smooth and the sugar has dissolved completely.
- Prepare the fish: Pat the black cod fillets dry with paper towels. Check for any pin bones and remove them with fish tweezers or pliers if necessary.
- Marinate the fish: Place the cod fillets in a shallow dish and pour the miso mixture over them, making sure each piece is thoroughly coated. Cover with plastic wrap and refrigerate for 24-48 hours (minimum 12 hours, but longer is better).
- Preheat your oven: When ready to cook, set your oven to broil and position a rack about 6 inches from the heat source. Line a baking sheet with parchment paper.
- Remove excess marinade: Gently wipe off the excess marinade from the fish fillets with your fingers, leaving just a thin coating. Too much marinade will burn under the broiler.
- Broil the fish: Place the fillets skin-side down on the prepared baking sheet and broil for 8-10 minutes until the top is caramelized and the fish is opaque and flakes easily with a fork. The internal temperature should reach 135°F.
- Rest briefly: Allow the fish to rest for 1-2 minutes before serving to let the juices redistribute.
- Serve immediately: Garnish with sliced scallions and a sprinkle of sesame seeds. Serve with steamed rice and a simple vegetable side like steamed bok choy or a cucumber salad.
Notes
- The long marination time is crucial for the flavors to penetrate and for the enzymes in the miso to tenderize the fish.
- Black cod (sablefish) is the traditional choice for this dish due to its high fat content and buttery texture, but you can substitute with sea bass, salmon, or even cod in a pinch.
- Watch the fish carefully during broiling—the high sugar content in the marinade can cause it to burn quickly.
- This dish can be prepared up to the marination step 2-3 days in advance, making it perfect for entertaining.
- For a lighter version, reduce the sugar to 1-2 tablespoons.

Common Mistakes to Avoid
- Skipping the marination time: The extended marination is essential for developing the signature flavor and texture. Don’t rush this step.
- Using too much marinade when cooking: Excess marinade will burn under the broiler, creating bitter flavors. Gently wipe most of it off before cooking.
- Overcooking the fish: Black cod is forgiving due to its high fat content, but it can still become dry if cooked too long. Look for caramelization on top and an internal temperature of 135°F.
- Using low-quality miso: The miso is the star ingredient here. Invest in good-quality white miso paste for the best flavor profile.
- Forgetting to check for pin bones: Nothing ruins a luxurious fish experience like unexpected bones. Take the time to check and remove them before marinating.
Alternatives & Substitutions
- Fish options: Sea bass, salmon, or Chilean sea bass work well as substitutes for black cod.
- Miso varieties: White miso is traditional, but you can experiment with yellow or red miso for a stronger flavor (though the color will be darker).
- Sake substitutes: Dry white wine or dry sherry can replace sake in the marinade.
- Mirin alternatives: Mix 1 tablespoon rice vinegar with 3 tablespoons white wine and 1 teaspoon honey or sugar.
- Sweetener options: Brown sugar, honey, or maple syrup can replace granulated sugar for different flavor profiles.
- Dairy-free/gluten-free: This recipe is naturally dairy-free; just ensure your soy sauce is gluten-free if needed.
FAQs
Can I marinate the fish for less than 24 hours?
While the recipe works best with a 24-48 hour marination, you can get away with as little as 12 hours. The flavor won’t penetrate as deeply, but you’ll still get delicious results. If really pressed for time, even 4-6 hours will impart some flavor.
Why is black cod so expensive and is it worth it?
Black cod (sablefish) is expensive due to its limited availability and high oil content that creates its signature buttery texture. For this dish, it’s worth the splurge if possible, as its natural fat content perfectly complements the miso glaze. However, good substitutes include Chilean sea bass or salmon.
Can I freeze the marinated fish before cooking?
Yes! You can marinate the fish and then freeze it for up to one month. Thaw overnight in the refrigerator before cooking. This makes for excellent meal prep or planning ahead for special occasions.
How do I know when the fish is perfectly cooked?
The fish is done when it’s opaque throughout and flakes easily with a fork. For precision, use an instant-read thermometer to check for an internal temperature of 135°F. The top should be caramelized to a beautiful golden-brown, but watch carefully to prevent burning.
What side dishes pair well with Miso Glazed Black Cod?
Traditional Japanese accompaniments include steamed white rice, miso soup, and simple vegetables like steamed bok choy or a cucumber salad. The richness of the fish pairs beautifully with clean, simple flavors. A side of pickled ginger can also help cleanse the palate between bites.
