Step‑by‑Step Instructions for Miso Glazed Black Cod
Step 1: Prepare Marinade
In a medium saucepan, combine white miso, sake, mirin, and brown sugar. Heat over medium heat for about 5 minutes, stirring occasionally until the sugar completely dissolves and the mixture is smooth. Remove from heat and allow the marinade to cool to room temperature. This savory sauce will be the heart of your Miso Glazed Black Cod.
Step 2: Marinate Fish
In a spacious, sealed container, place the black cod fillets and pour in two-thirds of the cooled marinade. Ensure each fillet is well coated. Seal the container and refrigerate for at least 30 minutes or up to 3 days for maximum flavor infusion. The longer the cod sits, the more rich and complex the flavor of the Miso Glazed Black Cod will become.
Step 3: Bake Fish
Preheat your oven to 400°F (200°C) while the fish marinates. Once preheated, line a baking sheet with parchment paper and lightly grease it. Remove the cod from the marinade, allowing excess to drip off, and place the fillets on the prepared baking sheet. Bake for 8-10 minutes, until the fish is opaque and begins to flake easily with a fork.
Step 4: Broil Fish
After baking, turn your oven to broil for a finishing touch. Broil the cod for an additional 2-3 minutes, watching closely for a golden brown color to develop on top. This step adds a delightful caramelization to the Miso Glazed Black Cod, enhancing both its appearance and flavor profile.
Step 5: Prepare Vegetables
While the cod bakes, heat a tablespoon of oil in a large skillet over medium-high heat. Add chopped bok choy stems and sliced shiitake mushrooms to the pan, cooking for about 2-3 minutes until they soften. Stir in minced garlic and sauté for another 30 seconds, letting the aroma fill your kitchen.
Step 6: Finish Vegetables
Add the bok choy leaves, dashi or broth, and soy sauce to the skillet with the sautéed stems and mushrooms. Stir well and simmer for another minute or two until the leaves wilt and become tender. Remove the pan from heat, adding a drizzle of toasted sesame oil for an enriched flavor that perfectly complements your Miso Glazed Black Cod.
Step 7: Serve
To plate, spoon the sautéed vegetable mixture onto each serving plate, creating a bed for the Miso Glazed Black Cod. Gently place the fish on top of the bed of bok choy and mushrooms. Finish with a drizzle of the reserved marinade over the fish. Optionally, you can garnish with sliced green onions or sesame seeds for an extra touch of elegance.

Make Ahead Options
These Miso Glazed Black Cod fillets are ideal for meal prep aficionados! You can prepare the marinade and store it in the refrigerator for up to 1 week, allowing the delightful flavors to develop. Additionally, marinate the black cod in two-thirds of the mixture for 30 minutes to 3 days prior to cooking; the longer the fish sits, the richer the flavor will be. If short on time, simply marinate for at least 30 minutes before baking. When you’re ready to serve, just bake and broil as directed, ensuring that your Miso Glazed Black Cod is just as delicious and succulent as if it were made fresh that day. This approach not only saves you time but allows you to enjoy scrumptious, hassle-free meals even on busy weeknights!
