Make the miso marinade.
1.Combine white miso paste, sake, mirin, and sugar in a small saucepan over medium heat.2.Whisk continuously until sugar dissolves and mixture is smooth, about 2 minutes.3.Remove from heat and stir in grated ginger. Let cool completely.TIPDon't let the marinade boil — you just want to dissolve the sugar and meld the flavors gently. - prep · ~2 min
Marinate the black cod.
1.Pat the black cod fillets dry with paper towels and sprinkle both sides with a pinch of salt.2.Place fillets in a shallow dish and pour the cooled miso marinade over them, turning to coat evenly.3.Cover and refrigerate for at least 30 minutes, preferably 2 to 4 hours.TIPFor best results, marinate overnight. The longer soak deepens the umami without overpowering the delicate fish. - prep · ~5 min
Preheat the broiler.
Position an oven rack about 6 inches from the broiler element. Preheat broiler on high for 5 minutes. Lightly grease a foil-lined baking sheet with vegetable oil.
TIPLine your baking sheet with foil for easy cleanup — caramelized miso can be sticky. - grill · ~8 min
Broil the black cod until caramelized.
1.Remove fillets from marinade and gently wipe off excess — a thin glaze should remain. Place skin-side down on the prepared baking sheet.2.Broil for 6 to 8 minutes without turning, until the top is deeply golden with bubbly, caramelized edges.3.Fish is done when it flakes easily with a fork and reaches an internal temperature of 130°F to 135°F.TIPWatch closely after the 5-minute mark — the sugar in the miso glaze can go from beautifully charred to burnt in seconds. - garnish
Garnish and serve immediately.
Transfer fillets to warmed plates. Scatter sliced green onions and toasted sesame seeds over the top. Serve with steamed rice and a simple cucumber salad on the side.
What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the black cod fillets dry before salting to ensure the marinade adheres evenly.
- 2Marinate for at least 2 hours, but overnight yields the deepest, most balanced umami.
- 3Wipe off excess marinade before broiling to prevent burning and ensure an even caramelized crust.
- 4Position the oven rack 6 inches from the broiler — too close and the sugar will char before the fish cooks through.
- 5Use a fish spatula to transfer fillets; they become delicate as they flake and can break apart.
- 6Line the baking sheet with foil for easy cleanup of the sticky, caramelized miso residue.
- 7Check internal temperature at the thickest part: 130-135°F is the sweet spot for silky, buttery texture.
Adapt it for your goals.
Gluten-free
Replace sake with dry sherry or a gluten-free sake, and ensure the mirin is labeled gluten-free (some brands contain wheat). Great for those with celiac or gluten sensitivity.
lower sugarLower sugar
Reduce sugar to 1 teaspoon and add a splash more mirin, or substitute with a low-calorie sweetener like monk fruit to cut the sugar while maintaining some caramelization.
salmon or troutSalmon or trout
Replace black cod with king salmon or arctic char — both have high fat content that responds well to the miso glaze, though you may need to reduce broiling time by 1-2 minutes.
air fryerAir fryer
Cook marinated fillets in an air fryer at 380°F for 8-10 minutes (no flipping) for a crispier exterior and faster cooking with less heat in the kitchen.

Frequently asked questions
Regular cod is leaner and drier, so it won't achieve the same buttery texture. If substituting, reduce broiling time and baste with extra marinade to prevent drying out.
