Brown Butter Miso Cod

Overnight miso cure caramelises under the grill into something impossibly savoury. One of those recipes that looks far more impressive than the effort deserves.

Method

  1. Whisk together the miso, mirin, sake and sugar. Coat the cod fillets all over, cover and refrigerate overnight — or at minimum 4 hours.

  2. When ready to cook, scrape off the excess marinade (it will burn). Heat your grill/broiler to maximum.

  3. Brown the butter in a small pan until nutty and amber. Keep warm.

  4. Place the cod on a lined tray and grill 6–8 minutes — no need to flip — until the surface is deeply caramelised and the fish flakes at the thickest point.

  5. Rest 2 minutes. Spoon the brown butter over the top, finish with spring onion.

Notes

White siso (shiro) is milder and sweeter than red. Don’t substitute — red miso will overwhelm the fish. The overnight cure is what makes this dish; don’t skip it.

Progressions

JUN 20, 2026 ★★★★★

Pushed the char much further than felt comfortable — that bitterness against the salty butter is the whole dish.

JUN 3, 2026 ★★★★☆

Lovely but timid. Needs more colour, more marinade time. 24 hours is the minimum.

The caramelisation is the point — don't be afraid to let it go dark. The miso sugars need real heat to develop properly.
