If you adore dishes with deep savory flavor and silky texture, this Japanese-style miso black cod is bound to become your next go-to recipe. The miso marinade melts into the tender fish, creating a beautiful balance of sweet, salty, and umami. Serve it with a bowl of steamed rice for an easy yet elegant meal.
My first go at this recipe was to impress guests for a holiday meal and it was such a hit I now make it for cozy dinners at home. Every time I cook it the aroma brings back those first memories of laughter and good food.
Ingredients
- White miso paste: Adds deep savory flavor and creaminess Choose fresh miso from an Asian market if possible for best taste
- Mirin: Brings a gentle sweetness and touch of glossiness Good quality mirin makes a difference and can be found in most grocery stores
- Rice vinegar: Balances richness with brightness Try to use unseasoned rice vinegar for a clean tang
- Sugar: Boosts caramelization and balances the salt
- Soy sauce: Layers in extra umami and a hint of color Use a naturally brewed soy sauce for the smoothest flavor
- Sake: Makes the fish extra tender and fragrant Choose a basic drinking sake or simply use water if unavailable
- Black cod fillets: This fish is prized for its buttery silky flesh and rich taste Always buy from a trusted fishmonger and check for firm shine to the skin
- Lemon wedges: Adds a fresh contrast to the rich fish Use bright yellow fruit with thin skin for best flavor
- Green onions: A sprinkle provides color and a little crunch Opt for snappy fresh onions and slice thinly
Step-by-Step Instructions
- Marinate the Fish:
- Whisk together miso mirin rice vinegar sugar soy sauce and sake in a bowl until the mixture is smooth and blended with no lumps. Taste the marinade for balance and adjust as you like. Place the black cod fillets in a shallow dish and coat evenly with the marinade making sure all sides are covered. Cover and refrigerate for at least 24 hours and up to 2 days. The long marinade deeply infuses flavor and tenderizes the fish.
- Prepare for Cooking:
- Gently wipe excess marinade from the cod fillets with your fingers or a paper towel. Leaving a thin layer adds flavor but too much can burn. Let the fish rest at room temperature for 30 minutes before cooking so it cooks evenly.
- Cook the Fish:
- Heat your oven broiler for five minutes. Line a baking tray with parchment or foil and lightly oil the surface. Place cod fillets skin side down on the tray. Place under the broiler on the middle rack and broil for about seven to ten minutes. The surface should be caramelized and gently blistered and the fish should flake at the edges.
- Garnish and Serve:
- Transfer fillets to plates using a spatula. Top with sliced green onions and a squeeze of fresh lemon if you like. Serve immediately with steamed rice and simple vegetables for a complete meal.

White miso is my favorite because it gives a gentle sweetness without overwhelming the fish. I remember the first time my mom tasted this dish with me at home her eyes lit up and she asked for seconds.
Storage Tips
Leftover miso cod can be kept in an airtight container in the refrigerator for up to two days. Gently reheat in a low oven or steam for best results. Avoid microwaving so you keep the flaky texture and glossy glaze.
Ingredient Substitutions
If black cod is not available you can use salmon or sea bass for similarly rich results. Try a two to one mix of white and yellow miso for more complexity. Use maple syrup or honey in place of sugar for a subtler sweetness.
Serving Suggestions
Serve on a mound of sushi rice or next to quick sautéed bok choy and edamame. A sprinkle of sesame seeds adds more flavor and a pretty finish. I love pairing this dish with miso soup for a cozy Japanese style dinner.
