The magic is time in the marinade. Two to three full days let the salt and sugar work deep into the fatty flesh, changing its texture the whole way through, so a quick broil at the end just caramelizes what the marinade already built.

The Ingredients — and where to get them
Cook for2servings
Black cod fillets
Sablefish; its high fat handles the sugar without drying. Wild-caught has the best texture.
Can you make Miso Black Cod in an air fryer? — Yes
Yes — this is exactly what an air fryer does well. Work in a single layer so the air can move, and shake or flip halfway for even crisping. It runs a touch faster than the oven, so check early.
Can you freeze Miso Black Cod? — Not ideal
You can, but the crisp coating softens. Freeze the cooked pieces, then re-crisp them in a hot oven or air fryer — never the microwave.
Can you make Miso Black Cod ahead of time? — Yes
Yes — it holds well and often tastes better the next day. Make it ahead and reheat gently before serving.
Is Miso Black Cod gluten-free? — Yes
Yes — nothing in this recipe as written contains gluten. As always, glance at the labels on any packaged items (broth, sauces, chocolate), since brands vary.
Is Miso Black Cod vegan? — No
No — it contains seafood, so it isn’t vegetarian or vegan.
