This recipe brings Nobu’s legendary miso-glazed black cod to your home kitchen with professional precision. The dish balances sweet, salty, and umami flavors in a way that feels restaurant-worthy yet achievable.
The key lies in marinating the Chilean sea bass in white miso, mirin, and sake for 48 hours. This transforms the fish into a buttery, tender masterpiece with a caramelized glaze. Noble simplicity meets bold flavor.
When baked at 400°F, the miso crust forms a perfect golden finish while keeping the interior moist and flaky. The result is a dish that’s as visually stunning as it is delicious.
Serve with steamed rice and garnish with fresh cilantro for an authentic touch. The wait is worth it.
Ingredients for Miso Chilean Sea Bass Recipe Nobu
A few quality ingredients transform this fish into a restaurant masterpiece. Nothing complicated here.
| Ingredient | Amount | Notes |
|---|---|---|
| Chilean Sea Bass Fillets 🐟 | 1 ½ lb | Skin-on, about 1-inch thick |
| White Miso Paste 🥣 | ½ cup | Fermented, smooth variety |
| Mirin 🍶 | ⅓ cup | Sweet rice cooking wine |
| Sake 🍶 | ⅓ cup | Dry Japanese rice wine |
| Sugar 🍚 | 2 tbsp | Granulated white sugar |
| Soy Sauce 🫕 | 2 tbsp | Low-sodium preferred |
| Fresh Ginger 🌿 | 1 tbsp | Peeled and grated |
| Steamed Rice 🍚 | 2 cups | Jasmine or short-grain |
| Fresh Cilantro 🌿 | ¼ cup | Chopped for garnish |
| Vegetable Oil 🫒 | 1 tbsp | For greasing baking dish |
The Chilean sea bass is non-negotiable here—look for wild-caught at Whole Foods or a reputable fishmonger. The fillets should be thick (about 1-inch) so they hold up to the long marinade. Miso paste can be found in the refrigerated section at Trader Joe’s or Asian markets. White miso is sweeter and milder, perfect for this glaze.
No mirin? Substitute dry sherry plus 1 tsp sugar per tbsp. Sake can be swapped for dry white wine in a pinch. The sugar helps caramelization, but honey works too (though it’s slightly more assertive). If you’re short on time, you can marinate for 24 hours, but 48 is ideal for that signature texture.
Marinated fish keeps in the fridge for up to 3 days before cooking. Leftovers taste amazing cold the next day—great in salads. The miso marinade freezes well for 1 month if you want to prep ahead.

Step-by-Step Instructions for Miso Chilean Sea Bass
Here’s the method that transforms simple ingredients into Nobu’s legendary dish.
Step 1: Marinade the Chilean Sea Bass Fillets
In a bowl, whisk together the 0.5 cup White Miso Paste, 0.33 cup Mirin, 0.33 cup Sake, 2 tbsp Sugar, 2 tbsp Soy Sauce, and 1 tbsp Fresh Ginger until smooth. The sugar should fully dissolve into the liquid, creating a glossy paste.
Pat the 1.5 lb Chilean Sea Bass Fillets completely dry with paper towels. Place them in a shallow dish and pour the marinade over, ensuring all surfaces are coated. Cover and refrigerate for 24-48 hours—this is non-negotiable for achieving that signature buttery texture.
Step 2: Prep for Baking
Preheat your oven to 400°F. Remove the fillets from the marinade and gently wipe off excess with your fingers—don’t rinse or you’ll wash away flavor. The surface should look slightly tacky but not dripping.
Lightly grease a baking dish with the 1 tbsp Vegetable Oil. Place the fillets skin-side down in the dish. The skin should be in full contact with the oil to prevent sticking during baking.
Step 3: Bake Until Caramelized
Bake on the middle rack for 10-12 minutes until the tops develop a glossy, caramelized crust. You’ll see the marinade bubble and darken slightly—this is the miso sugars caramelizing, which creates that iconic Nobu glaze.
Then increase heat to 450°F and bake for another 2-4 minutes until the edges turn deep golden brown and the fillets flake easily when tested with a fork. Watch closely during this final phase to prevent burning.
Step 4: Rest and Serve
Remove from oven and let rest for 3-5 minutes in the baking dish. This allows the juices to redistribute through the fish, ensuring that buttery texture Nobu is famous for.
Serve immediately over 2 cups Steamed Rice, spooning any pan juices over the top. Garnish with 0.25 cup Fresh Cilantro for a bright finish. The fish should be tender enough to cut with a butter knife, with a perfect balance of sweet, salty, and umami flavors.
Pro Tips For Making Miso Chilean Sea Bass Recipe Nobu
- Marinate Overnight: I learned this the hard way—give the sea bass at least 12 hours in the miso-mirin-sake marinade, or the flavors won’t penetrate the dense flesh.
- Pat Fish Dry: After marinating, blot the fillets thoroughly with paper towels to guarantee a good sear instead of a steamed exterior.
- Skip Boiling Marinade: Resist the urge to boil the leftover marinade for sauce—miso burns easily and turns bitter; reduce gently on low heat instead.
- Use Skin-Side Down First: Start searing the sea bass skin-side down in a screaming hot pan for 3-4 minutes to crisp it perfectly before flipping.
Flavor Customization for This Dish
Spicy Miso Glaze
Add 1 tsp gochujang or ½ tsp cayenne pepper to the marinade for a subtle heat that complements the sweetness. I love how the spice cuts through the richness without overpowering the dish. 🌶️
Citrus Brightness
Stir 1 tbsp yuzu juice or zest of 1 lime into the finished glaze for a vibrant, tangy lift. The citrus brightens the umami flavors beautifully, making each bite more dynamic.
Sweet and Nutty
Mix 1 tbsp toasted sesame seeds into the marinade for a nutty depth, or sprinkle them on top before baking. This adds a delightful crunch and visual contrast to the caramelized glaze.
Herb Variation
Swap the cilantro garnish for thin-sliced scallions or microgreens for a different fresh note. Scallions add a mild onion flavor that pairs wonderfully with the miso’s savory profile.
Extra Umami Boost
Add 1 tsp white truffle oil to the marinade for a luxurious twist. This elevates the dish with earthy complexity, perfect for special occasions.
Smoky Depth
Use smoked paprika or a dash of liquid smoke in the marinade for a subtle smoky undertone. It mimics the char from a wood-fired oven, adding another layer of flavor. 🔥

Frequently Asked Questions
Can I use black cod instead of Chilean sea bass?
Yes! Black cod is actually the traditional choice at Nobu. The texture and flavor are nearly identical. Just ensure the fillets are 1-inch thick for best results.
Why does the fish need to marinate for 48 hours?
The long marinade breaks down proteins in the fish, creating that signature buttery texture. 24 hours works in a pinch, but 48 hours delivers the full Nobu experience.
What if my marinade isn’t smooth?
Strain it through a fine-mesh sieve to remove ginger fibers. A smooth marinade ensures even coating and better caramelization during baking.
Can I make this without sake or mirin?
Substitute dry white wine for sake and dry sherry plus 1 tsp sugar for mirin. The flavor won’t be identical, but it’ll still be delicious.
