Miso Sea Bass • Succulent Miso Glazed Chilean Sea Bass • Two Purple Figs

Miso Sea Bass, and particularly Miso glazed chilean sea bass is one of those iconic dishes you’ll often see on high-end restaurant menus. Buttery, flaky white fish with a rich sweet savory glaze that caramelizes beautifully under heat. This recipe feels luxurious yet is surprisingly simple to recreate at home. Follow the step by step below and try it!

This miso fish recipe uses one of our absolute favorites, the Chilean Sea Bass. Combine that with the phenomenal Nobu style  Miso Black Cod using a marinade of miso paste, sake, soy sauce, and sugar. You get a genius miso sea bass that tastes heavenly!

The marinade penetrates through the super delicate fish, infusing it with layers of umami. Once cooked, the Chilean sea bass practically melts in your mouth, balanced by the crisp glaze on top.

We have made this Miso Salmon as well and LOVED it, so we had to explore more fish options!

While this is particularly a fancy seafood dish, one that’s perfect for a romantic dinner, it’s SO EASY so you’ll make it more often! You’ll find yourself making it for entertaining guests, or just to elevate a weeknight meal.

What Is Miso Glazed Chilean Sea Bass?

Miso glazed sea bass is a Japanese inspired dish made by marinating Chilean sea bass in a mixture of miso paste, soy sauce, sake or mirin, and sugar. Then the fish is  cooked in the oven. It can be broiled or roasted until caramelized. The rich, fatty texture of sea bass pairs perfectly with miso’s salty-sweet umami profile, creating a dish that’s both delicate and indulgent.

While Nobu famously popularized this preparation worldwide, the technique is rooted in Japanese cooking. Miso marinades are traditionally used for fish. Today, it’s a global favorite that symbolizes elegance and flavor harmony. It became popular on social media even for those who haven’t visited his restaurants.

• Soy sauce. For extra richness and umami

How to Make Miso Glazed Chilean Sea Bass

1. Make the marinade. Start by mixing the miso paste, sugar, soy sauce and sake or mirin or rice viengar in a bowl. Whisk that together until it looks like a smooth paste.
   
2. Marinate the fish. Take the chilean sea bass and slather it with the miso mixture marinade. Make sure to coat the fillets on both sides and edges, and everywhere.
3. Now let the fish marinate in the refrigerator for at least 30 minutes or up to overnight.
4. Prepare the baking pan. You can use a baking sheet pan with a rack, or use a regular baking sheet lined with foil. Avoid using parchment paper with the broil.
   
5. Cook the fish. Preheat the oven’s broiler to the highest setting. Place the sheet pan about 8 inch from the heat source, so basically on the first rack.
6. Broil the fish until golden brown with the top caramelized, and the fish flakes easily.
   
7. Garnish & serve right away with a sprinkle with chilli, sesame seeds, green onions, or a squeeze of citrus for brightness.
8. You can use our popular Chili Oil Recipe for another level of flavor. You’ll notice more notes of garlic and ginger with that.

Miso Sea Bass Recipe Tips

1. Black Cod and Chilean Sea Bass are both expensive fish, so make sure you get them from a good source.
2. If you want a more affordable option, make this Miso Salmon.
3. Use white miso for a mild, sweet flavor. Red miso paste will give a stronger, saltier glaze. If you’re only using the red, then increase the sugar to double.
4. You don’t need salt for this recipe, as the miso and soy sauce provide eough.
5. Avoid over marinating. 30 minutes is enough, and up to 12 hours. More than that,  the miso can overpower the delicate fish.
6. Broiling gives the best caramelization, but roasting at high heat works too.
7. Don’t over cook the fish! If you’re broiling it, as soon as the color turns golden and the fish flakes easily, it’s ready.
8. For a citrusy twist, add a touch of yuzu juice or lime juice before serving.
9. To make it spicy, add chilli flakes to garnish the fish.
