Ingredients
For the Classic Miso Black Cod
-
4 black cod fillets (6 oz each), skin-on, deboned
-
1/4 cup white miso paste
-
3 tbsp mirin
-
3 tbsp sake
-
2 tbsp sugar
-
1 tbsp soy sauce (low-sodium)
Optional Garnish
-
Toasted sesame seeds
-
Thinly sliced green onions
-
Pickled ginger or radish slices
Substitutions
-
Black cod → Chilean sea bass or salmon (if unavailable)
-
White miso → Yellow miso (slightly stronger taste)
-
Mirin → Mix of rice vinegar and sugar
-
Gluten-free → Use tamari instead of soy sauce
Step-by-Step Cooking Instructions
1. Prepare the Marinade
In a small saucepan, combine miso paste, mirin, sake, sugar, and soy sauce. Heat gently over low heat until smooth and sugar is dissolved. Let it cool.
2. Marinate the Fish
Place the black cod fillets in a resealable bag or shallow dish. Coat thoroughly with the cooled marinade. Cover and refrigerate for at least 24 hours, up to 3 days for a deeper flavor.
3. Preheat and Prep
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil. Lightly oil the surface to prevent sticking.
4. Bake the Black Cod
Remove excess marinade (do not rinse). Place fillets skin-side down on the tray. Bake for 10–12 minutes, or until the fish is opaque and flakes easily with a fork. For caramelization, broil the last 2 minutes.
5. Optional: Sear for Finish
For a restaurant-style crust, quickly sear the fish in a nonstick skillet for 30–60 seconds on high heat before serving.
Pro Tips and Cooking Techniques
-
Use skin-on fillets for extra flavor and to help hold the fish together.
-
Don’t over-marinate fish longer than 3 days to avoid overly salty flavors.
-
Use a fish spatula for delicate handling to avoid breaking the fillets.
-
To get a beautiful glaze, lightly dab excess marinade off before baking.
-
Always cook fish just until it flakes—overcooking dries out the buttery texture.

Frequently Asked Questions (FAQs)
1. Can I freeze black cod before or after marinating?
Yes! Freeze raw black cod before marinating. For best flavor, do not freeze it after it’s been marinated or cooked.
2. How do I know if black cod is done cooking?
The fish should be opaque and flake easily with a fork. It should reach an internal temperature of 145°F (63°C).
3. Can I grill instead of bake?
Absolutely. Grill skin-side down over medium heat for about 4–5 minutes per side. Watch for flare-ups due to the marinade’s sugar.
4. How long can I store leftovers?
Refrigerate cooked black cod in an airtight container for up to 3 days. Reheat gently in a microwave or skillet.
5. What if I can’t find miso?
Use a simple soy-honey-ginger marinade as an alternative.
