Kyoto Miso-Lacquered Cod

Kyoto Miso-Lacquered Cod-

Silken flakes of cod meet the deep, savoury warmth of Japanese miso in this beautifully simple dish that feels both refined and comforting. The fish is gently marinated in a glossy blend of white miso, mirin, and a touch of sweetness, then roasted until the glaze turns caramelised and fragrant.

The result is wonderfully tender cod with a delicate balance of sweet, salty, and umami — the kind of dish that feels quietly luxurious without asking much of the cook. Served with steamed rice, wilted greens, or a scatter of sesame and spring onion, it’s the sort of elegant supper Flora loves: simple ingredients, treated with care, letting flavour do all the talking. 🍶✨

A little corner of Japan, brought softly to the Hartwell Kitchen table.

Prepare

10 mins

Cook

15 mins

Serving

4 people

Ingredients

4 fresh cod fillets (about 170 g / 6 oz each)
3 tablespoons white miso paste
2 tablespoons mirin
1 tablespoon soy sauce
1 tablespoon honey
1 teaspoon rice vinegar
1 teaspoon sesame oil
1 garlic clove, finely minced

To serve
2 cups fresh greens
2 cups warm cooked white rice

A small collection of simple ingredients, brought together for a beautifully balanced dish — savoury miso, gentle sweetness, and delicate cod that flakes apart with the lightest touch.

Method

  1. Prepare the oven
    Preheat the oven to 200°C (400°F), or place a non-stick skillet over gentle medium heat if cooking on the stovetop.

  2. Create the miso glaze
    In a small bowl, whisk together the white miso paste, mirin, soy sauce, honey, rice vinegar, sesame oil, and minced garlic until the mixture becomes smooth and glossy.

  3. Prepare the cod
    Lightly oil a baking dish or skillet and arrange the cod fillets inside. Brush each fillet generously with the miso glaze, coating the surface evenly.

  4. Allow the flavours to mingle
    Let the cod marinate for at least 30 minutes, allowing the savoury sweetness of the glaze to gently infuse the fish. Meanwhile, prepare the fresh greens and warm the rice.

  5. Cook the cod
    Bake for 12–15 minutes, until the glaze begins to caramelise and the cod flakes easily with a fork.
    Alternatively, pan-sear the fillets for about 4 minutes per side until beautifully golden.

  6. Finish with a final glaze
    During the final moments of cooking, brush the cod with a little extra glaze to create a rich, lacquered finish.

  7. Serve
    Spoon steamed rice onto warm plates, nestle the miso-glazed cod on top, and add a handful of fresh greens. Drizzle any remaining glaze over the dish and serve immediately.

A simple, elegant dish where delicate cod meets the deep savoury sweetness of miso — the sort of quietly luxurious supper I love to bring to the Hartwell Kitchen table. 

Helpful Tips

Flora’s Kitchen Notes

For deeper flavour, allow the cod to marinate overnight in the refrigerator. The miso glaze gently infuses the fish, creating an even more luxurious taste.

For a gluten-free table, simply swap the soy sauce for tamari — it offers the same rich, savoury depth without the wheat.

For a lightly crisp finish, place the cod under the grill (broiler) for the final 2 minutes of cooking, allowing the glaze to caramelise into a beautiful golden lacquer.

To finish, scatter over toasted sesame seeds or finely sliced spring onions, adding a delicate crunch and a fresh lift of flavour.

A few small touches that turn a simple dish into something quietly special — the Hartwell Kitchen way.
