Creating the incredible Black Cod Miso Glazed is straightforward when you follow these steps:

1. Prepare the Marinade: In a bowl, combine the miso paste, mirin, sake, brown sugar, soy sauce, sesame oil, and grated ginger (if using). Mix until smooth.
2. Marinate the Fish: Place the black cod fillets in a resealable plastic bag or a shallow dish. Pour the marinade over the fish, ensuring it’s fully coated. Seal the bag or cover the dish and refrigerate for 24 hours.
3. Preheat the Oven: When ready to cook, preheat your oven to 400°F (200°C).
4. Remove Excess Marinade: Take the fish out of the marinade and gently wipe off any excess with a paper towel, leaving a thin layer of the glaze.
5. Bake the Fish: Place the black cod on a lined baking sheet. Bake in the preheated oven for 15-20 minutes or until the fish is opaque and flakes easily with a fork.
6. Broil for Extra Glaze: For a caramelized finish, switch the oven to broil and broil the fish for an additional 2-3 minutes. Watch closely to prevent burning.
7. Garnish: Once cooked, remove from the oven and transfer to a serving platter. Garnish with chopped green onions and sesame seeds.
