This miso-marinated black cod features a crispy, caramelized glaze and melt-in-your-mouth texture, perfect for an elegant yet easy dinner. The marinade infuses the fish deeply, creating a sweet and savory umami flavor.

Ingredients

Scale
  • 3 tablespoons white miso paste (smooth, mild like Hikari)
  • 3 tablespoons mirin (good-quality brand like Takara)
  • 2 tablespoons sake (or dry white wine as substitute)
  • 1 tablespoon granulated sugar
  • 4 black cod fillets (about 6 ounces each, skin on)
  • 1 tablespoon neutral oil (grapeseed or vegetable oil)
  • Optional garnishes: thinly sliced scallions or chives, toasted sesame seeds, lemon wedges

Instructions

  1. Prepare the miso marinade by whisking together white miso paste, mirin, sake, and granulated sugar until smooth and slightly thick but pourable.
  2. Pat the black cod fillets dry with paper towels. Place them skin-side down in a shallow glass dish. Pour the marinade evenly over the fillets, coating all surfaces. Cover tightly with plastic wrap and refrigerate for at least 24 hours (up to 48 hours for deeper flavor).
  3. Remove the cod from the fridge 20 minutes before cooking to come closer to room temperature. Gently wipe off excess marinade with paper towels to prevent burning.
  4. Heat a non-stick or well-seasoned cast-iron skillet over medium heat and add neutral oil. Wait until the oil shimmers but does not smoke.
  5. Place the fillets skin-side down in the skillet. Press gently with a fish spatula for about 10 seconds to keep the skin flat. Cook without moving until the skin is golden brown and crispy, about 5-6 minutes.
  6. Flip the fillets carefully and cook the other side for 2-3 minutes until the fish flakes easily but remains moist inside.
  7. Transfer the cooked cod to plates. Garnish with scallions or sesame seeds if desired and serve immediately with lemon wedges.

Notes

Marinate the fish skin-side down for even flavor absorption and moisture retention. Wipe off excess marinade before cooking to avoid burning. Cook over medium heat and preheat the pan well. Flip gently using a fish spatula. Avoid overcrowding the pan; cook in batches if needed. Leftovers can be stored in an airtight container in the fridge for up to 2 days and reheated gently in a pan to preserve crispiness.
