How to Make the Recipe

Step 1: Prepare the Marinade

In a bowl, whisk together white miso, sake, mirin, and brown sugar until smooth and well combined.

Step 2: Marinate the Fish

Place black cod fillets in a shallow dish or resealable bag and coat evenly with the marinade. Cover and refrigerate for at least 30 minutes, up to 3 days.

Step 3: Cook the Vegetables

Heat oil in a skillet over medium heat. Add garlic, baby bok choy, and shiitake mushrooms. Sauté until tender, about 5 minutes.

Step 4: Add Flavor to Vegetables

Pour in dashi or broth, soy sauce, and toasted sesame oil. Cook for another 2 minutes until vegetables are glazed and flavorful.

Step 5: Cook the Black Cod

Preheat oven to 400°F (200°C). Place marinated cod on a baking sheet lined with parchment paper. Bake for 10 minutes or until fish flakes easily with a fork.

Step 6: Serve

Plate the cooked black cod over the sautéed baby bok choy and shiitake mushrooms. Drizzle with any reserved marinade for extra flavor.

Tips for Making the Recipe

• Use fresh, high-quality black cod for the best buttery texture.
• Do not over-marinate fish beyond 3 days to avoid overpowering the delicate texture.
• When baking, watch carefully to avoid drying out the fish—black cod cooks quickly.
• For added caramelization, broil the fish for the last 1-2 minutes.
• Reserve some marinade before adding the fish for use in cooking vegetables or drizzling on the dish.

How to Serve

• Serve immediately after baking over warm, sautéed greens and mushrooms.
• Pair with steamed jasmine rice or sticky rice to soak up the glaze.
• Add a side of pickled ginger or a light cucumber salad for freshness.
• Complement with a crisp, chilled white wine like Sauvignon Blanc or Chardonnay.
• Garnish with sliced scallions or toasted sesame seeds for a beautiful finish.

Make Ahead and Storage

Storing Leftovers

Keep cooked fish and vegetables refrigerated in airtight containers for up to 2 days. Best enjoyed fresh.

Freezing

Freezing cooked black cod is not recommended as the texture can become mushy.

Reheating

Gently reheat leftovers in a low oven or microwave, covered to retain moisture, but be careful not to overcook.
