It is the vivid green tangle that turns up on appetiser lists at almost every sushi restaurant, and it looks like nothing else on the menu. Most people either order it every time or have never ordered it at all.
What is seaweed salad?
Seaweed salad is an edible seaweed – usually wakame – rehydrated and dressed with sesame oil, vinegar and sesame seeds. It is served cold, in a small portion, as a starter or a side.
The texture is the thing that surprises people. It is not soft or slippery in the way the appearance suggests. It has a definite spring to it, closer to a firm noodle than to a leaf.

What the seaweed actually is
Wakame is a brown seaweed, despite what ends up on the plate. It grows in cool coastal waters, has been farmed in East Asia for centuries, and is one of the most widely cultivated seaweeds in the world – NOAA covers the scale of seaweed aquaculture and how it is grown.
It arrives at a restaurant dried, in dark compressed pieces, and is rehydrated in water before use. It expands considerably when it does – a small handful of dry seaweed becomes a bowlful.

Why it is so green
The colour is the most-asked question and it has a straightforward answer. Wakame shifts from brown to bright green when it hits hot water, because heat breaks down the brown pigment and reveals the green underneath.
Some prepared versions are also coloured to make that green more uniform, which is why restaurant seaweed salad tends to be a more emphatic colour than a home-made version. Both start from the same seaweed.

What goes into the dressing
The dressing is where restaurants differ, but the components are consistent.
- Sesame oil – the dominant flavour, toasted and nutty.
- Rice vinegar – the sharpness that keeps it from being heavy.
- A little sweetness – usually sugar or mirin, balancing the vinegar.
- Sesame seeds – scattered through, adding texture as much as flavour.
- Sometimes chilli – a small amount of heat in some house versions.
Occasionally you will find slivers of cucumber or carrot mixed through it. That is a house variation rather than a different dish.

How it is prepared
There is more to it than mixing, and the steps explain why restaurant versions are consistent while home attempts often are not.
- The dried seaweed is soaked in cool water until it opens out, which takes only a few minutes and expands it several times over.
- It is drained and then squeezed firmly, because water left in the strands dilutes the dressing and makes the whole thing limp.
- It is cut into even lengths, so it can be picked up cleanly rather than arriving as one tangle.
- It is dressed and then left to sit, which lets the sesame and vinegar work into the strands rather than coating them.
The squeezing step is the one most often skipped and the one that matters most. It is the difference between springy and soggy.
How it differs from the seaweed elsewhere on the menu
| Seaweed salad | Nori | Seaweed in miso soup | |
|---|---|---|---|
| Type | Wakame, usually | Pressed sheets | Wakame, usually |
| Form | Long shredded strands | Flat dried sheet | Small soft pieces |
| Served | Cold, dressed | Wrapped around rice | Floating in hot broth |
| Texture | Springy and firm | Crisp, then soft | Soft |
| Flavour | Sesame and vinegar | Toasted and savoury | Mild, takes on the broth |
It is worth knowing that the seaweed in a miso soup and the seaweed in the salad are frequently the same thing, prepared completely differently. If you like one and not the other, it is the preparation you are responding to.

One practical note on colour: a duller, browner green is not a sign that anything is wrong. It usually means the seaweed has not been dyed, and the flavour is unaffected either way.
What it tastes like
Sesame first, then vinegar, then a clean mineral flavour underneath that is the seaweed itself. It is savoury and slightly sweet, and the sea note is much milder than the appearance suggests.
If you have avoided it on the assumption that it tastes strongly of the sea, that assumption is worth testing. The dressing does most of the talking.
Why the portion is small
Seaweed salad almost always arrives in a small mound rather than a bowlful, and that is deliberate rather than mean. The dressing is concentrated, the texture is assertive, and the flavour does not fade as you eat it.
A large portion of it would dominate a table in a way a leaf salad would not. It is built to be a counterpoint – a few forkfuls between other things – rather than something to work through.
When to order it
It works best in the same slot as a palate cleanser – early, or alongside something rich. The vinegar and the cold temperature both cut through fried food, which is why it sits comfortably next to an order of anything crisp.
Portions are small, which makes it easy to add to a table without committing much. It is also one of the few appetisers that holds up well if it sits for a few minutes, because it is already cold and already dressed.
Other seaweed dishes you may come across
Wakame dressed with sesame is by far the most common version, but seaweed is a broad category and a few other preparations turn up in Japanese and wider East Asian cooking.
- Kombu – a thick kelp used mainly to build broth rather than eaten as a salad, though it is sometimes sliced and served.
- Hijiki – fine dark strands, usually simmered rather than dressed cold, with a much softer texture.
- Cucumber and wakame – the same salad with thin cucumber slices through it, sharper and lighter than the plain version.
If you enjoy the standard version, these are the natural next steps, and all of them start from the same idea of treating seaweed as a vegetable rather than a garnish.
It also sits well next to almost anything. Because the dressing is sesame and vinegar rather than anything creamy or heavy, it does not compete with a soup, a grilled plate or a tray of rolls, which is part of why it turns up on so many tables as an extra rather than a decision.
Does it travel?
Better than most things. It is served cold, it does not depend on a crisp texture, and the dressing is already on it, so nothing is lost between the kitchen and home.
The only thing worth doing is keeping it separate from anything hot in the bag. It is at its best cool, and it will sit happily in the fridge for a short while if the rest of the meal arrives first.

Frequently Asked Questions
What is seaweed salad made of?
Rehydrated seaweed, usually wakame, dressed with sesame oil, rice vinegar, a little sweetness and sesame seeds. It is served cold.
Why is seaweed salad so green?
Wakame is brown when dried and turns bright green when it meets hot water, as heat breaks down the brown pigment. Some prepared versions are also coloured for consistency.
What does seaweed salad taste like?
Sesame and vinegar lead, with a clean mineral flavour underneath. It is much milder than most people expect, and the texture is springy rather than soft.
Is it the same seaweed as in miso soup?
Often yes – wakame is used in both. The difference is preparation: shredded and dressed cold for the salad, in small soft pieces in hot broth for the soup.
Is seaweed salad the same as nori?
No. Nori is pressed into flat sheets and used to wrap rolls. Seaweed salad is a different form entirely, served loose and dressed.
