Wakame Salad (Japanese Seaweed and Cucumber Salad)

The Japanese Seaweed Salad You Will Actually Crave

If you have ever sat down at a Japanese restaurant, spotted that glistening little bowl of seaweed salad, and thought I wish I could make this at home, you are in exactly the right place. This wakame salad is fresh, deeply savory, and tangy in the most satisfying way. It comes together in about 15 minutes and requires zero cooking. Honestly, it might become one of the most-requested things you make.

This version takes the classic Japanese seaweed and cucumber combination, sometimes called sunomono, and builds it into a complete, flavor-forward salad with a sesame-soy dressing brightened by fresh ginger and rice vinegar. It is vegan, gluten-friendly with a simple swap, and packed with nutrients that actually make you feel good.

What Is Wakame, Exactly?

Wakame is a type of edible seaweed used widely across Japanese and Korean cuisines. You have probably encountered it floating in miso soup or served as a side dish at a sushi restaurant. It has a silky, slightly chewy texture and a mild oceanic flavor that pairs beautifully with sesame and vinegar.

For this recipe, you will use dried wakame, which is easy to find at Asian grocery stores or online. It rehydrates in minutes and expands to a remarkable volume, so a small bag goes a long way.

Chef's Tip: Do not over-soak your wakame. Five to ten minutes in cold water is all it needs. Over-soaking makes it slimy rather than silky.

Why This Dressing Makes All the Difference

The soul of any great healthy Japanese seaweed salad is its dressing. This one is a simple ratio of soy sauce, unseasoned rice vinegar, and toasted sesame oil, balanced with just a touch of sugar and amplified by fresh ginger and garlic. Every ingredient earns its place here.

Using toasted sesame oil rather than plain is non-negotiable for depth of flavor. Similarly, fresh ginger grated on a microplane gives a brightness you simply cannot replicate from a jar.

Having the right kitchen tools and quality pantry staples truly elevates this salad from good to restaurant-worthy. A fine microplane, good-quality toasted sesame oil, and authentic Japanese rice vinegar are the small investments that pay off in every bite.

The Cucumber Trick You Cannot Skip

If you have ever made a cucumber seaweed salad that turned into a watery mess by the time you served it, the culprit was the cucumber. Cucumbers hold a lot of moisture, and once they hit the dressing, they release it all.

The fix is simple. Toss your thinly sliced cucumber with a little salt, let it sit for five minutes, then rinse and pat it completely dry. This draws out excess liquid before it ever touches your beautiful dressing, keeping your spicy cucumber and seaweed salad crisp from the first bite to the last.

Chef's Tip: Use a mandoline if you have one for paper-thin, even cucumber slices. They will absorb the dressing more evenly and give the salad a polished, restaurant-style look.

Building Your Bowl

Once your wakame is rehydrated and your cucumber is prepped, assembly is quick and deeply satisfying. Toss everything with the dressing, taste and adjust the balance, and finish with a generous shower of toasted sesame seeds and sliced green onions.

For a spicy cucumber and seaweed salad, a pinch of red pepper flakes stirred into the dressing adds a gentle, lingering heat that works beautifully against the cool cucumber. It is completely optional but highly recommended if you enjoy a little kick.

USM

Scale

1x2x3x

• 1/2 oz dried wakame seaweed, about 2 tablespoons dry; will expand significantly once rehydrated
• 1 English cucumber, thinly sliced into rounds
• 1/2 tsp kosher salt, for drawing moisture out of the cucumber
• 2 tbsp soy sauce, low-sodium preferred
• 2 tbsp rice vinegar, unseasoned
• 1 tbsp sesame oil, toasted, for best flavor
• 1 tsp granulated sugar, or substitute with honey
• 1 tsp fresh ginger, finely grated
• 1 garlic clove, minced or grated
• 1 tbsp toasted sesame seeds, white or a mix of white and black
• 2 green onions, thinly sliced, for garnish
• 1/4 tsp red pepper flakes, optional, for a spicy kick

Instruction

1

Place the dried wakame in a medium bowl and cover with cold water. Let it soak for 5 to 10 minutes until fully rehydrated and tender. Drain well, gently squeeze out excess water with your hands, and if the pieces are large, roughly chop them into bite-sized lengths. Set aside.

2

While the wakame soaks, place the thinly sliced cucumber in a colander set over a bowl. Sprinkle with the kosher salt, toss to coat, and let sit for 5 minutes. This draws out excess moisture so your salad stays crisp and not watery. Rinse the cucumber briefly under cold water, then pat very dry with paper towels.

3

In a small bowl, whisk together the soy sauce, rice vinegar, sesame oil, sugar, grated ginger, and minced garlic until the sugar is fully dissolved.

4

Combine the drained wakame and prepared cucumber in a large mixing bowl. Pour the dressing over the top and toss gently until everything is evenly coated.

5

Taste and adjust seasoning. Add a pinch more sugar for sweetness, a splash more rice vinegar for tang, or red pepper flakes for heat.

6

Transfer to a serving bowl and garnish generously with toasted sesame seeds and sliced green onions. Serve immediately or refrigerate for up to 30 minutes before serving for a slightly deeper flavor.

Equipment

• Large mixing bowl
• Medium bowl (for soaking wakame)
• Colander
• Small whisk
• Mandoline or sharp chef's knife
• Fine grater or microplane (for ginger and garlic)

Notes

This salad is best served the day it is made. If prepping ahead, store the dressing, cucumber, and wakame separately and toss together just before serving to prevent sogginess. Leftover dressed salad keeps in an airtight container in the refrigerator for up to 1 day. Dried wakame can be found in Asian grocery stores, health food stores, or online. A little goes a long way since it expands to roughly 6 to 8 times its dry volume once rehydrated.

Serving and Storing

Wakame salad shines as a starter, a side dish alongside grilled salmon or teriyaki chicken, or even as a light lunch on its own. It also fits naturally into a larger spread of Japanese-inspired dishes.

Serve it:

• Alongside steamed rice and miso soup for a classic Japanese meal
• As a refreshing side to grilled proteins
• Paired with sushi or onigiri for a complete spread
• As a standalone light lunch with a sprinkle of extra sesame seeds

This salad is best enjoyed fresh, ideally within a couple of hours of tossing. If you are meal prepping, keep the components separate and combine them just before serving. The wakame and cucumber both hold well individually in the refrigerator for up to a day.
