Miso-Glazed Black Cod

Method

1. Make the miso marinade. Whisk together miso paste, mirin, sake, sugar, and soy sauce until smooth. The marinade should be thick like paste, not runny.

2. Marinate the cod. Coat each fillet generously with the miso paste, place in a container, cover, and refrigerate for 24–72 hours. The miso enzymes slowly break down the surface proteins while infusing the fish with umami.

3. Preheat the broiler to high. Line a sheet pan with parchment paper or foil.

4. Wipe excess marinade off each fillet with your fingers or a paper towel. Leave a thin layer — you want flavor, not a thick crust of burned miso. Place the fillets on the prepared pan.

5. Broil for 8–10 minutes about 6 inches from the element. The miso glaze should caramelize and char in spots — dark brown with some blackened edges is correct. The fish is done when it flakes easily and the internal temperature reaches 130°F. Black cod is so fatty that it's almost impossible to overcook.

6. Serve immediately. The fish should be silky, rich, and deeply savory with a sweet-salty caramelized crust. Pair with steamed rice and pickled ginger.

• Container for marinating

Chef Notes

• The most important thing: Marinate the cod for at least 24 hours, ideally 48–72 hours. The miso needs time to penetrate the dense, fatty flesh. A quick marinade barely flavors the surface. The longer the marinade, the more deeply the sweet-savory miso flavor permeates.
• Black cod (sablefish) is the traditional fish — it's extremely fatty and rich, which stands up to the intense miso glaze. If you can't find it, salmon or Chilean sea bass work but have different textures.
• Wipe off excess marinade before cooking. The sugar in the miso burns quickly under high heat. A thin residual layer is fine — thick globs will char black.
• Broil, don't bake. The intense top-down heat caramelizes the miso glaze into a lacquered, slightly charred crust in 8–10 minutes. Baking takes longer and doesn't produce the same caramelization.
• This is Nobu Matsuhisa's signature dish — it put miso-glazed fish on the global map. The recipe is deceptively simple.

Common Substitutions

Ingredient	Substitution	Notes
Black cod (sablefish)	Salmon or Chilean sea bass	Salmon is leaner; sea bass is firmer. Both work well
White miso	Red miso (use 2 tbsp)	Stronger and saltier — reduce the amount
Mirin	1 tbsp rice vinegar + 1 tbsp sugar	Approximates mirin's sweet-tangy flavor
Sake	Dry white wine	Similar alcohol content for the marinade
Broiler	Oven at 400°F, 12–15 min	Less caramelization but still good

What You're Practicing

Miso-glazed black cod teaches you enzyme marination — using miso's natural enzymes to tenderize and flavor protein over days, not hours. This is a different approach from acid-based marinades (lime, vinegar) that work in hours. Enzyme marinades (miso, koji, yogurt) work slowly and deeply. Visit Brines, Cures & Marinades for more on marination science.
