Buttery Miso Glazed Black Cod Ingredients

For the Marinade

• Miso Paste – Delivers the signature savory umami flavor.

• Mirin – Adds subtle sweetness and enhances the overall balance.

• Sake – Provides depth and complexity to the marinade.

• Brown Sugar – Helps balance the salty ingredients while encouraging caramelization.

• Soy Sauce – Adds an extra layer of savory flavor and richness.

For the Fish

• Black Cod Fillets – Choose fresh, high-quality fillets for the best texture and flavor.

• Cooking Oil (Optional) – Useful for lightly greasing the baking tray and preventing sticking.

Step-by-Step Instructions for Buttery Miso Glazed Black Cod

Step 1: Make the Marinade

In a medium mixing bowl, combine 3 tablespoons miso paste, 2 tablespoons mirin, 2 tablespoons sake, 2 tablespoons brown sugar, and 1 tablespoon soy sauce. Whisk thoroughly until the mixture becomes smooth and the sugar is completely dissolved. This flavorful marinade forms the foundation of the dish and infuses the fish with its signature taste.

Step 2: Marinate the Fish

Pat the black cod fillets dry using paper towels. Place the fillets in a shallow container or resealable bag and pour the marinade over them. Make sure every piece is evenly coated. Cover or seal the container and refrigerate for 12 to 24 hours. Turn the fillets halfway through the marinating time to ensure even flavor distribution.

Step 3: Preheat the Oven

Set your oven to 400°F (200°C). Line a baking sheet with parchment paper while the oven heats. This prevents sticking, simplifies cleanup, and helps the glaze caramelize evenly during baking.

Step 4: Prepare the Cod

Remove the marinated cod from the refrigerator. Gently scrape away excess marinade using a spoon or spatula, leaving behind a thin coating on the surface. This prevents the glaze from burning while still providing plenty of flavor.

Step 5: Bake the Fish

Arrange the fillets on the prepared baking sheet, leaving a little space between each piece. Bake for 10 to 12 minutes. The fish is ready when it turns opaque and flakes easily with a fork while remaining moist and tender inside.

Step 6: Broil for a Golden Finish

Transfer the baking sheet to the upper oven rack and switch the oven to broil. Broil for 1 to 2 minutes, keeping a close eye on the fish. The glaze should become bubbly and develop a beautiful golden-brown color.

Step 7: Rest and Serve

Remove the fish from the oven and allow it to rest for approximately 2 minutes. This helps the juices settle throughout the fillets. Garnish with sliced green onions before serving for a fresh and vibrant finishing touch.
