Why You’ll Love this Miso Black Cod Recipe

The miso-based marinade gives the black cod a rich, sweet, and complex flavor that caramelizes beautifully under the broiler. The finished fish is tender and flaky with a glossy, caramelized exterior. While marinating takes time, a full day in the fridge yields the best depth of flavor — it’s worth the wait.

Prep Like a Pro

Choose the right fish — Ask your fishmonger for black cod (sablefish) with pin bones removed for the best texture and eating experience.

Use a non-reactive container — Marinate in glass or ceramic. Avoid metal, which can react with the miso and change the flavor.

Wrap tightly — Seal the fish well before refrigerating to prevent oxidation and maintain freshness.

Marinate — For best results, marinate for 24 hours; if short on time, marinate at least 4 hours.

Broiler — Preheat the broiler to high (around 550°F) and watch closely, as the sugars in the marinade caramelize quickly.

Internal temperature — Broil on the middle rack for about 7 minutes, depending on your oven. The cod should be opaque and flake easily. For accuracy, use an instant-read thermometer at the thickest part: 135°F for medium-rare (recommended) or 145°F if you prefer well done.

Substitutions

  • Swap black cod for salmon or Chilean sea bass if desired.
  • To make this vegetarian, use thick slices of eggplant or meaty mushrooms instead of fish.

Chef Nadia’s Tip

Marinating longer develops a deeper flavor. Aim for 24 hours when possible; if not, allow at least 4 hours.

The Perfect Pairings

Begin with a bright cucumber-based cocktail. For sides, serve the cod over a bed of fragrant rice and a crisp cucumber-fennel salad. Finish with warm caramelized peaches for dessert. These combinations balance the sweet, savory, and fresh elements of the miso cod.

Miso Black Cod Recipe: Questions Answered

What miso do you use?

I use mellow white miso, which is sweet and ideal for glazing fish.

Can I use a different fish?

Yes. Salmon, Chilean sea bass, or other firm, fatty fish work well with this marinade.

What mirin do you use?

Use a sweet cooking mirin for balance in the glaze.

How can I make this vegetarian?

Substitute thick slices of eggplant or large, meaty mushrooms and treat them the same way in the marinade.
