Step‑by‑Step Instructions for Buttery Miso Glazed Black Cod
Step 1: Prepare Marinade
In a mixing bowl, whisk together ¼ cup miso paste, 3 tablespoons mirin, 2 tablespoons sake, 2 tablespoons brown sugar, and 1 tablespoon soy sauce until the mixture is smooth and well-combined. This luscious marinade will bring rich umami flavors to your Buttery Miso Glazed Black Cod.
Step 2: Marinate Fish
Pat the black cod fillets dry with paper towels to ensure the marinade clings well. Place the fillets in a shallow dish or a resealable bag, then pour the marinade over the fish, ensuring they are fully submerged. Seal tightly and refrigerate for 12 to 24 hours, flipping the fillets halfway through for maximum flavor infusion.
Step 3: Preheat Oven
When ready to cook, preheat your oven to 400°F (200°C). While the oven warms, line a baking sheet with parchment paper to prevent sticking and make cleanup easier. The parchment also helps achieve a beautifully caramelized finish on your Buttery Miso Glazed Black Cod.
Step 4: Prepare Fillets
After marinating, remove the black cod fillets from the marinade and gently shake off any excess. This step is crucial for even caramelization during baking. Arrange the fillets skin-side down on the prepared baking sheet for even cooking and to enhance the dish’s presentation.
Step 5: Bake Fish
Place the baking sheet in the preheated oven and bake the black cod for about 10 to 12 minutes. Keep an eye on the fish; it should appear opaque and flake easily with a fork when done. This gentle baking allows the buttery miso glaze to infuse into the fish without drying it out.
Step 6: Broil
Once the cod is baked, switch the oven settings to broil and move the baking sheet to the top rack. Broil the fish for 1 to 2 minutes, watching closely to avoid burning, until the glaze is bubbly and beautifully golden brown. This step enhances the flavor profile of the Buttery Miso Glazed Black Cod.
Step 7: Rest and Serve
After broiling, remove the black cod from the oven and let it rest for about 2 minutes. This brief rest allows juices to redistribute for a more tender bite. Serve your Buttery Miso Glazed Black Cod garnished with sliced green onions for a pop of color and added freshness on the plate.

Make Ahead Options
These Buttery Miso Glazed Black Cod fillets are perfect for meal prep enthusiasts! You can prepare the marinade up to 24 hours in advance, whisking together the miso paste, mirin, sake, brown sugar, and soy sauce. Simply pat the black cod fillets dry and submerge them in the marinade in a resealable bag or shallow dish, refrigerating them overnight will help deepen the flavor. When you’re ready to serve, preheat your oven and bake the marinated fish for 10-12 minutes, followed by a quick broil for 1-2 minutes until bubbly and golden. This approach makes weeknight dinners a breeze, allowing you to enjoy a restaurant-quality meal with minimal effort!
