White miso and butter create an unexpectedly rich glaze that builds flavor in layers as it bakes. The sauce caramelizes on top while keeping the cod flaky and moist underneath.

Ingredients
2 piececod fillets, 150-200g each
½ cupwhite miso
30 mlsake
30 mlmirin
30 mllight soy sauce
1 tbspunsalted butter
Optional Pre-Salting
1 tspsalt per fillet(optional)
Instructions
For firmer texture, cover both fillets with a generous coating of salt and let them sit at room temperature for 10 minutes. Rinse thoroughly under cold water and pat completely dry with paper towels.
⏱ 10 min
Add the miso, sake, mirin, soy sauce, and butter to a small saucepan over low-medium heat. Whisk continuously until the butter melts and the miso dissolves into a smooth mixture, then bring to a rolling boil.
Heat your oven to 390°F and arrange the cod fillets on a baking sheet. Pour the hot miso mixture directly over each fillet, making sure they're completely coated.
Bake for 3 minutes, then remove and spoon any pooled sauce back over the fish. Return to the oven for another 3 minutes, checking that the internal temperature hits 130°F. If needed, give it 1-2 more minutes.
⏱ 8 min
Let the cod rest for 1-2 minutes before plating — this helps the glaze set slightly and prevents it from sliding off.
