Miso Marinated Black Cod

This Miso Marinated Black Cod is incredibly easy to make, and is perfect over steamed rice with stir-fried vegetables! If you can’t find Black Cod in your area, any firm white fish would work for this recipe.

Miso Marinated Black Cod Recipe

Black cod is such a treat, but this fish is relatively rare to find in markets. Contrary to popular belief (and the actual name of the fish) Black Cod isn’t actual cod at all. This fish is commonly known as Sablefish, Butterfish, Alaska cod, and Coalfish. It has a buttery, rich flavor, and it is highly prized.

We do a lot of fishing around here, and occasionally are fortunate enough to pull one of these up from the depths of the Pacific Ocean off the coast of Washington State. If you want to order yours, they have it available via Crowd Cow, and it is well worth it!

How to make Miso Black Cod

This is just the overview so you can see what you’re actually getting into here. When you are cooking, you’ll want to use the full recipe at the bottom of the page.


Mix the marinade

The miso, sake, mirin, shoyu, and sugar all go into a large sealable baggie.


Marinate the fish

Around 4 hours in the fridge is minimum. You can leave it overnight as well.


Rinse and dry

Your mileage may vary here, but we prefer to give the fish a quick rinse and dry before cooking. You can skip if you’d like a bolder flavor.


Preheat your cast iron pan or Blackstone griddle

Hot pan is a must! You want it around 350° on the surface of your pan. I love my Thermapen IR for measuring surface temps!


Cook the fish

It doesn’t take long for fish filets. About 3 minutes per side should be about right.

What can you serve with miso cod?

We served this with a big scoop of steamed basmati rice. Jasmine rice would also be a great option. One of our great fried rice recipes would also work really well here!

If you’re already cooking outside, some of our Traeger Asparagus would be perfect alongside.

Miso-Marinated Cod FAQ

What’s the best way to store leftover black cod?

There isn’t really an ideal way to store this. Leftover fish shouldn’t really be a thing, so do your best to only cook as much as you want to eat. If you do overshoot it, make sure to store it in the fridge for more than a day or two. I’d suggest gently reheating it in a hot water bath for any leftovers. Stay away from the microwave ;).

Can you use other types of fish?

Sure! Any firm white fish should work for this recipe. Experiment and let me know how it goes!

Miso Marinated Black Cod is easy to prepare, and such a treat! If you can't get your hands on the relatively hard-to-find Sablefish, any firm whitefish will work!

Prep Time 5 minutes
Cook Time 8 minutes
Marinate Time 4 hours
Total Time 4 hours 13 minutes


  • 4 8-ounce Black Cod filets
  • 1/3 cup white miso
  • 1/4 cup sake
  • 3 tablespoons Mirin
  • 2 tablespoons sugar in the raw
  • 2 tablespoons shoyu soy sauce
  • 1 tablespoon oil


  1. Wash and pat dry your fish filets. Mix together the white miso, sake, mirin, sugar, and soy sauce. Place the marinade and the fish into a sealable baggie and refrigerate for at least 4 hours.
  2. Remove the fish from the marinade and rinse off the excess marinade and pat dry with paper towels.
  3. Preheat your cast iron pan or Blackstone griddle over medium heat. You want the surface temperature to be around 350°.
  4. Put a thin layer of oil into the pan or onto the griddle, and cook the fish for about 3 minutes per side. 145° is the official USDA safe temp for fish. We like ours more around 135°.
  5. Serve over rice with a drizzle of soy glaze or soy sauce and sriracha.
