What is Miso Cod?

Black Cod with Miso or simply Miso Cod (銀だらの西京焼き) is a beloved and classic dish served at many formal Japanese restaurants. It became world-famous more recently thanks to the acclaimed Japanese fine restaurant chain Nobu.

The preparation for this dish requires marination with a specific sweet white miso that originates from the Kyoto (formerly Saikyo) area. The marinade is called Saikyozuke (西京漬け) and includes just three ingredients: Saikyo miso (西京味噌), mirin, and sake. Once the fish is grilled, it’s called Saikyoyaki (西京焼き).

Why I Love This Recipe

  • It requires only a few simple ingredients. The traditional marinade uses only 3 ingredients! I’ll show you how to substitute regular white miso if you can’t find Saikyo miso.
  • Super easy prep for an elegant dish. With only 10 minutes of active prep time, you can sit back and relax while the fish marinates for 2 days. Then cook it for 20 minutes and serve. All in all, a fuss-free recipe!
  • Meal prep-friendly! After marination, you can individually wrap the uncooked fish and store it in a freezer bag for up to 2–3 weeks. When ready to cook, just defrost it in the fridge. I love pre-marinating this fish during the busy holiday season.

Substitutions

  • Saikyo miso – You can use regular white miso if you can’t find Saikyo miso. Simply add 1 Tbsp sugar for every 6 Tbsp white miso.
  • Sablefish (black cod) – I buy fresh black cod from my local Japanese supermarket. You can also find sustainably caught Alaskan black cod from online seafood companies in the US. If you can’t get sablefish, I recommend using sea bass and salmon.
  • Sake and mirin – For this recipe, do not replace the sake and mirin with water. If you use water instead, it can spoil during the lengthy marination and ruin the fish.

How to Make Miso Cod

Preparation

Step 1 – Salt the fish. Sprinkle kosher salt over the sablefish fillets and set it aside for 30 minutes to draw out the excess moisture and reduce the fish‘s odor.

Step 2 – Make the marinade. Meanwhile, mix the Saikyo miso, sake, and mirin for the marinade. Mix to dissolve the miso completely and pour the marinade into a container.

Step 3 – Marinate the fish. Pour sake over the fish to rinse off the salt and pat dry with a paper towel. Place the fish in the container and coat both sides with the marinade. Cover and marinate in the refrigerator for 2–3 days.

Cooking

Step 4 – Wipe off the marinade completely. With your fingers, remove all the marinade from the fish. Place the fish skin side up on a baking sheet lined with parchment paper or a silicone mat.

Step 5 – Bake the fish. Preheat the oven to 400°F (200ºC) and bake until the surface is blistered and a bit charred and browned, about 20 minutes. You do not need to flip the fish.

Step 6 – Serve. Carefully remove the fish with a spatula and discard any burnt miso from the fish. Serve immediately on individual plates. We always eat this dish with rice.

Nami’s Recipe Tips

  • Use Saikyo miso for the best flavor – This Kyoto-style white miso has a wonderfully sweet, mild flavor. Along with the mirin, it makes a sharp and sweet marinade that works wonderfully to cut the fish’s richness. You can purchase it on Amazon or at your local Japanese/Asian grocery stores.
  • Marinate for at least 2 days. To develop a succulent texture in the fish, I marinate it for at least 2–3 days until the sweet and salty flavor gets completely absorbed. The fillets are sometimes marinated for up to 4–5 days in Japan, but it can get quite salty and dry, so it’s usually best as an accompaniment to plain steamed rice.
  • Bake it to avoid burning. Although I often broil different types of fish, I recommend baking this miso cod especially if you have never tried the broiling method before. Miso burns really easily; while you can’t avoid burning miso completely, you can minimize it by baking this fish.
  • Wipe off the marinade completely. With your fingers, do your best to remove as much of the marinade from the fish as possible. Do not leave any excess marinade on the fish; otherwise, it will burn easily while baking.

Variations and Customizations

  • Try it with sea bass or salmon. Black cod (sablefish) is known for its silky and tender rich texture and flavor, and is the preferred fish choice. If you can’t find it, sea bass and salmon also work well with this miso marinade. I alternate these three fish in my Saikyozuke and my family enjoys them equally. I don’t recommend fatty fish like tuna or mackerel due to the strong taste.
  • Use other types of miso. You can try this recipe using another type of miso besides Saikyo miso or regular white miso. Since other miso types are saltier than white miso, please adjust the flavor by adding more mirin and/or sugar. You should also reduce the marination time to several hours or overnight.

What to Serve with Miso Cod

Miso cod makes an impressive main dish as part of a classic Japanese ichiju sansai dinner. Prep it ahead, bake in the oven, and dinner is ready. I would serve it with steamed rice, a side of greens, and a simple soup. Here are some recipes that pair well with this beautiful dish:

Storage Tips

To store: You can keep the cooked leftovers in an airtight container and store it in the refrigerator for 3 days and in the freezer for up to a month.

To freeze uncooked: If you want to pre-marinate your fish to cook later, wipe off the marinade completely and individually wrap the fish with plastic wrap. Store it in a freezer bag for up to 2–3 weeks. Defrost in the refrigerator before cooking.

Frequently Asked Questions

Can I use water instead of sake?

We use sake to clean the fish and remove the odor. You can’t replace it with water, even though sometimes water is used as a replacement in other recipes. Since the marination time is long for this dish, the water can go bad and ruin the marinade and fish.

Can I use water instead of mirin?

For this recipe, please do not use water. If you want to omit the mirin, use sugar only. For 1 Tbsp mirin, use 1 tsp sugar instead.

To Remove the Marinade from the Fish

  • With your fingers, wipe off the marinade from fish completely. Do not leave any excess marinade on the fish; otherwise, it will burn easily.

To Bake (Recommended)

  • Preheat the oven to 400°F (200ºC) with a rack placed in the center of the oven. For a convection oven, reduce the cooking temperature by 25ºF (15ºC). Place the fish skin side up on a baking sheet lined with parchment paper or a silicone mat. Bake the fish until the surface is blistered and browned a bit, about 20 minutes. You do not need to flip the fish. Please remember the cooking time varies depending on the thickness of the fish.

To Broil (Optional)

  • Preheat the broiler* with a rack placed about 8 inches (20 cm) away from the top heating element (in the center of the oven) for 5 minutes. Tip: When broiling, you don‘t control the temperature in the oven; instead, you control the distance between the broiler and the surface of the food. It‘s similar to using hotter and cooler zones on your grill. *There are usually three broiler settings: Low (450ºF/232ºC), Medium (500ºF/260ºC), and High (550ºF/288ºC). I usually use the Medium (6 inches away) or High (8 inches away) setting.
  • Place the fish skin side up on the foil-lined baking sheet and broil on High (550ºF/288ºC) for 8–10 minutes until the surface is blistered and browned a bit. Please remember the cooking time varies depending on the thickness of the fish and the distance between the broiler and the food. You do not need to flip the fish.

To Serve

  • Carefully transfer the fish with a spatula and remove any burnt miso from the fish. Serve immediately. I serve the fish with thinly sliced red radishes and garnish it with a small green leaf from my backyard for additional color. We always eat this dish with rice.

To Store

  • You can keep the cooked leftovers in an airtight container and store it in the refrigerator for 3 days and in the freezer for up to a month.

Notes

  • Sake: Sake is used to clean and remove the odor of the fish. You can’t replace it with water even though sometimes water is used as a replacement in some recipes. We will marinate the fish for a longer time, and water can go bad and ruin the marinade and fish.
  • Mirin: Typically, mirin can be replaced with water and sugar, but for this recipe, please do not use water. If you want to omit the mirin, use sugar only. For 1 Tbsp mirin, use 1 tsp sugar.

Hi Nami,

I really enjoy your recipes and videos! I am looking forward to making the miso black cod soon. I had a question – I noticed you mentioned using an air tight container, would I be able to use my Corningware tightly covered with a couple layers of plastic wrap or what alternatives do you suggest if I do not have an air tight container?

Thank you for help!

Hi Abri, Yes. That should work well as an alternative. Thank you very much for your sweet feedback!

Thank you and you are welcome!

Hi Nami-san, thank you for the recipe. I tried cooking with the recipe today, but with a few variations – I used cod instead of black cod (bought the wrong kind of fish), and I cooked it in a toaster oven (425F, 15min) instead of a conventional oven. I did get a little bit of the miso flavour on the surface of the fish, although it was overpowered by the alcohol flavour from the mirin and/or the sake. I am going to try again next time with the right kind of fish and using a conventional oven (and perhaps coating in more salt at the beginning), but I was wondering if you have any tips as to how I can get a stronger miso flavour throughout and how I can eliminate the alcohol flavour entirely. Thank you!

Hi Hiro, Thank you very much for trying this recipe. To get a stronger miso flavor, we recommend marinating longer. How many days did you marinate the fish? You can marinate it for up to 3 days with this recipe. To eliminate the alcoholic flavor, baking a little longer than this time until the surface is blistered and brown a bit may help. We hope this helps!

I have commented on this recipe before as I absolutely love it (especially with salmon). I will now goes as far as to say that this was my favourite recipe discovery of 2020. And not only mine: I cooked this for several friends and one even said she dreamt of it afterwards. Thank you so much for this wonderful recipe – I already know that this is going to be a keeper for life. Wishing you a wonderful New Year!

Hi Afra!
Thank you very much for your love and support!
We are so happy to hear this recipe is going to be your keeper for life!☺️
We wish you a Happy New Year!

Hello, has anyone ever used Shio Koji to marinate the Black Cod? If so, would you still use white miso in the recipe and if so would you use the same amount or less?

Hi Suzanne,
Yes. You may use Shio Koji as well.
You may mix it with Miso or use Shio Koji only as you like. As for the amount, we recommend the same amount. But of course, you can add more or less for your liking.
We hope this helps!

How many ounces or pounds for this recipe?
Also, how wide should I cut the pieces into?

I bought 2.85lb (2 very long fish strips) of Alaskan/Pacific Cod at Costco.

Just wondering how wide should I cut/slice the pieces into, for marination and freezing/storing later.
2″, 3″, 4″ wide, etc.?

Thanks!

Hi Edgar,
Thank you very much for trying this recipe!
Nami’s slices are about 2.5″ wide.
We hope this helps!🙂

Thanks for the info!

I actually just sliced and marinated them an hour ago, and did 2-3″ wide slices… so I got lucky it is close to 2.5″.

I first did your recipe measurements (6tbs saikyo miso, 3tbs mirin, 3tbs sake) and it was enough to dip/cover a lot of fish! It did about 2lbs of my 2.85lb fish.
So, I made a smaller amount for the last pound (2tbs saikyo miso, 1tbs mirin, 1tbs sake), and that was perfect amount!

Hi Edgar,
Great! Thank you for trying this recipe!
We hope you enjoy this dish with warm steamed rice. Let us know how it goes.😉

Made this and it came out great, thank you! I baked it because I’m not good at broiling. Used a silicone mat (Silpat). I could not believe the fish survived just fine in the fridge after 3 ½ days. I guess the miso protected it. Ate it with sliced daikon.5 stars

Hi Dave!
Thank you very much for trying this recipe and for your kind feedback!🤩
We are so happy to hear it turned out great, and you enjoyed this dish.
Thank you for writing to us! 💕

Hello,
Thank you for this recipe! I love doing it but was wondering how you could use the rest of the marinade since you have to swipe any excess on the fish.
Thank you!

Hi Elodie,
We normally do not reuse the marinade sauce from this recipe.
However, you may use it for stir-frying or baking vegetables, etc. Please make sure to use heat and used up on the same day.
We hope this helps!

Hi there! Will this work with Dashi Miso?
Unfortunately that’s all I could find locally

Hi David!
We are sorry to hear that they only carry Dashi Miso. 😔
You may try this recipe with Dashi Miso, but the flavor will be different because it has other ingredients in the miso.
In your case, we recommend marinating for only 1~2 days, so the other ingredients would not overwhelm the flavor.
We hope this helps!

i accidentally got the black cod cut as steaks instead of cut as a fillet. Should i do anything differently due to the different cut?

Hi Ann,
How thick is your steak cut? If you can cut the steak in half and place the skin side up, we recommend doing that. Otherwise, please try marinating for a shorter time and make sure to remove the miso completely before you cook. Then adjust the cooking time because it will be no skin/barrier on top.
We hope this helps!☺️

Hi Nami!
This will be my first time making miso fish and I have 2 beautiful Chilean sea bass filets from a local farmers market, and got the Saikyo miso at 99 Ranch (woo Bay Area!). They are roughly an inch thick and have already had the skin removed. Should I make any cooking alterations because the skin won’t be there to provide a good barrier? I don’t want to burn these babies. Thanks!

Hi Kristen!
This time, we recommend not move around too much.
Chilean sea bass filets are flaky, so please be careful handling. Once it’s cooked, pieces can disintegrate and break apart because there is no skin that’s holding. Another note is, please try marinating for a shorter time and make sure to remove the miso completely before you cook. It’s seasoned enough, and you don’t need to leave any miso.
American fillet prefers non-skin, but please try one with the skin next time. It provides natural oil and tastes better with it.
Good luck!😊

In your miso salmon recipe you stated: “Cover and keep in the refrigerator for 30 minutes to 1 hour. I don’t recommend longer than that as miso is quite salty.” But in this miso black cod recipe you state to marinate at least 2-3 days and that I could substitute salmon for this recipe. Which one is correct or better? Thank you.

Hi Gary! Consider these two recipes are served differently. The longer-marinated fish is to enjoy with steamed rice (We consider it’s the accompaniment for rice ご飯のおかず – the main dish for rice) while Miso Salmon can be served even without rice. It’s just a different type of cooking/dishes. I hope this answers your question.

Great recipe and easy to follow for beginner cooks.

If you’re in Berkeley, CA go to Tokyo Fish Market to source some of the ingredients. I got the cod from there along with the mirin, sake, and miso paste.

Salting the fish definitely helped milden the fish flavor and aroma but the fish was really fresh so that wasn’t an issue. I charred the skin a bit too much and it left an intense flavor but sooooo good! I have a few more cut of fish marinating and can’t wait to see the difference in taste.

This would go well in a traditional Japanese breakfast spread or with rice and sunomono salad.5 stars

Hi! This recipe looks amazing! I doubled it as I’m using 2.5 pounds of fish for dinner tomorrow night. I have kind of big fillets, about 8 oz each. I was wondering if the baking time will need to be longer or should I cut them in half or is 8 oz ok?

I worked so hard for this and was so disappointed. Got all the right ingredients, followed the directions, and it looked nice but very little flavor at all!!!!! I’m not giving up but what do I do?????

I sometimes see fresh black cod/sable fish filets at Costco (fresh fish section). I’m not sure if they are seasonal but as with typical Costco items, each package is quite a lot. Thanks for this yummy recipe. Love the make-ahead idea (and freezable too)- oishii desu 😀
