Saba no Misoni (Mackerel Simmered in Miso)
Why this recipe works
- Layered savoury depth: Miso, soy sauce, sake and mirin create a rounded simmering sauce with saltiness, sweetness and umami in balance.
- Gentle simmering: Cooking the mackerel slowly in the sauce keeps the fish tender while allowing the glaze to coat the surface.
- Richness in check: Fresh ginger and sake help balance the natural oiliness of mackerel, keeping the finished dish clean rather than heavy.

Authenticity notes
- Home-style Japanese cooking: Saba no misoni is commonly treated as a simple rice accompaniment, with the sauce spooned over the fish rather than served as a separate broth.
- Serve with rice: Plain steamed rice is the natural pairing, as it absorbs the salty-sweet miso glaze and balances the richness of the mackerel.
Ingredient notes
- Choose skin-on mackerel: Skin-on fillets hold together better during simmering and give the dish its recognisable presentation.
- Use fresh ginger: Fresh ginger gives a cleaner, brighter flavour than dried ginger and helps soften the assertive taste of oily fish.
- Adjust red miso carefully: Red miso is usually saltier and deeper than white miso, so add it gradually and balance the seasoning to taste.
Texture tips
- Keep the simmer gentle: A low, steady simmer helps the mackerel stay moist and flaky rather than tightening or breaking apart.
- Avoid boiling the miso: Once the miso is whisked in, keep the heat controlled so the sauce stays smooth and glossy.
Make-ahead tips
- Reheat gently: Warm leftovers over low heat until piping hot, adding a little water if the miso glaze has thickened too much.
- Best eaten fresh: The fish is at its most delicate just after cooking, though leftovers can be refrigerated with the sauce for a short time.

Ingredients
Instructions
- Peel the ginger and slice it thinly. Trim the spring onions and slice them finely.
- In a saucepan, combine the sake, mirin, soy sauce and caster sugar, then bring to a gentle simmer over medium heat. Simmer for 2 minutes to dissolve the sugar.
- Lower the heat and whisk in the white miso until smooth. Add the ginger and return to a gentle simmer; the sauce should look glossy and lightly thickened.
- Slide in the mackerel, skin-side up, so it sits in a single layer. Simmer gently for 10 to 12 minutes, spooning the sauce over the fish a few times, until the flesh is opaque and flakes easily.
- Lift the fish out briefly, then simmer the sauce for 2 to 4 minutes until it coats the back of a spoon. Return the fish to the pan and turn it in the glaze to coat.
- Serve the mackerel with the sauce spooned over, and scatter with the spring onion. Let it stand for 2 minutes so the glaze settles on the fish.
Recipe notes
Tips
- Keep the simmer gentle once the miso is added; a hard boil can make the sauce taste harsh and may cause it to split.
- If your mackerel fillets are thick, add 2 to 3 minutes to the simmer and use the flake test to judge doneness.
- If serving to pregnant people, young children, older adults, or anyone immunocompromised, use alcohol-free sake and ensure the sauce is simmered well so the fish is piping hot throughout.
Substitutions
- Replace White miso with Red miso for a deeper, saltier flavour; start with a little less and adjust to taste.
- Replace Sake with dry white wine for a similar acidity and aroma.
- Replace Caster sugar with Honey for a rounder sweetness; whisk it in with the miso so it dissolves smoothly.
Storage
- Refrigerate up to 2 days
- Cool, then refrigerate in a sealed container with the sauce. Reheat gently in a saucepan over low heat until piping hot, adding a splash of water if the glaze has tightened too much.
