Hijiki Seaweed Salad is a traditional Japanese side dish that brings together the earthy taste of seaweed, tender vegetables, and a savory-sweet broth in one delicious preparation.
Made with dried hijiki seaweed, this flavorful dish is simmered with fried tofu pouches, carrots, and Japanese seasonings until the ingredients absorb the rich, balanced sauce.
Edamame adds a pop of green color and a pleasant, tender texture, making every serving look as inviting as it tastes.
The combination of soy sauce, mirin, and sugar creates a distinctive Japanese flavor profile that balances saltiness with gentle sweetness.
As the ingredients simmer in dashi, the seaweed softens and absorbs the seasoning, while the carrots contribute a subtle sweetness.
Fried tofu provides a satisfying texture and soaks up the flavorful cooking liquid. Optional konnyaku and lotus root introduce additional textural variety, making the salad even more interesting.
One of the best things about Hijiki Seaweed Salad is its versatility. It works beautifully as a side dish alongside rice, grilled fish, tofu, or other Japanese-inspired meals.
It is also a practical choice for bento lunch boxes because it can be prepared ahead of time and portioned for convenient serving throughout the week.
The flavors remain enjoyable even when the salad is served at room temperature.
Whether you are exploring Japanese home cooking or looking for a flavorful make-ahead side dish, this hijiki salad offers a delicious combination of savory seasoning, tender vegetables, and satisfying textures.
You can also adapt it to a vegan diet by choosing a suitable plant-based dashi.

Ingredients
Equipment
Method
- Soak the Hijiki Seaweed: Place the dried hijiki in a bowl and cover it with 4 cups of water. Soak mehijiki for 10 minutes or nagahijiki for 30 minutes, depending on the variety, while preparing the other ingredients.
- Drain and Rinse the Seaweed: Transfer the rehydrated hijiki to a large fine-mesh sieve. Drain thoroughly and rinse under running water.
- Blanch the Fried Tofu: Bring water to a boil in a small saucepan and pour it over the aburaage to remove excess oil. Squeeze out the liquid, cut each tofu pouch in half lengthwise, then slice it thinly crosswise.
- Boil the Konnyaku: Place the konnyaku in a small pot with water and bring it to a boil. Cook for 3 minutes to help remove its odor and improve its ability to absorb the seasoning. Drain, then cut it into small strips similar in size to the tofu slices.
- Prepare the Carrot: Peel the carrot if needed, then cut it into thin julienne strips.
- Slice the Lotus Root: If using pre-boiled lotus root, cut it into thin quarter-round pieces.
- Heat the Oil: Pour 1 Tbsp neutral oil into a medium pot and warm it over medium heat.
- Cook the Vegetables: Add the carrot and lotus root to the pot. Stir until the vegetables are evenly coated with oil.
- Add the Hijiki and Tofu: Add the drained hijiki, prepared konnyaku, and sliced aburaage to the pot. Stir gently to distribute the ingredients evenly.
- Pour in the Dashi: Add 2 cups of dashi to the pot and bring the liquid to a boil.
- Season the Salad: Stir in ¼ cup mirin, 2 Tbsp sugar, and ¼ cup soy sauce until the sugar is incorporated into the broth.
- Simmer Until Tender: Cover the pot and reduce the heat to medium-low. Simmer for 20–30 minutes, allowing the hijiki, tofu, and vegetables to absorb the savory-sweet seasoning.
- Add the Edamame: Stir in ⅓ cup cooked, shelled edamame and mix until evenly distributed throughout the salad.
- Reduce the Remaining Sauce: Remove the lid and continue cooking until the liquid has reduced and you can see the bottom of the pot when the ingredients are moved aside.
- Serve the Salad: Serve the hijiki salad as a side dish with a Japanese meal or portion it into a bento lunch box.For meal prep, divide it into individual servings in freezer-safe silicone cups if desired.
- Store the Leftovers: Allow the salad to cool, then transfer it to an airtight container and refrigerate for 3–4 days.Alternatively, freeze individual portions for up to 1 month.
Notes
-
Choose the right hijiki: Mehijiki consists of small, soft buds and needs about 10 minutes of soaking, while nagahijiki has longer, chewier stems and requires about 30 minutes.
-
Rinse thoroughly: Drain the rehydrated seaweed and rinse it under running water before cooking.
-
Prepare the tofu properly: Pour boiling water over the aburaage and squeeze out the excess liquid to remove excess oil before slicing.
-
Customize the vegetables: Konnyaku, lotus root, and edamame are optional, so you can adjust the combination according to your preference and availability.
-
Adjust the sweetness: The salad traditionally has a sweet-savory flavor. Reduce the sugar from 2 tablespoons to 1 tablespoon if you prefer a less-sweet result.
-
Choose your dashi carefully: For a vegan version, use shiitake-kombu dashi instead of a stock containing fish.
-
Reduce the broth sufficiently: Uncover the pot near the end of cooking and continue simmering until most of the liquid has evaporated and the bottom of the pot becomes visible when you move the ingredients.
-
Make ahead: Refrigerate the finished salad in an airtight container for 3–4 days or freeze it in individual portions for up to one month.
Chef’s Secret
The secret to a flavorful Hijiki Seaweed Salad is allowing the ingredients enough time to absorb the seasoning before reducing the broth completely.
After adding the dashi, mirin, sugar, and soy sauce, keep the pot covered and maintain a gentle simmer over medium-low heat for the full 20–30 minutes specified in the recipe.
This gives the hijiki, tofu, and vegetables time to take on the savory-sweet flavors without rushing the cooking process.
Once you add the edamame, uncover the pot and continue cooking until the remaining liquid reduces and the bottom becomes visible when you move the ingredients aside.
Avoid stopping while a large amount of broth remains, as the finished salad should be well seasoned rather than watery.
Serving Suggestions
Serve Hijiki Seaweed Salad alongside steamed Japanese rice, miso soup, grilled fish, or teriyaki tofu for a balanced Japanese-inspired meal.
It also pairs well with grilled chicken, baked salmon, or vegetable tempura when you want a variety of textures and flavors on the table.
For a traditional bento lunch, portion the salad into a small compartment alongside rice, pickled vegetables, and your choice of protein.
You can serve it warm or at room temperature, making it convenient for meal preparation.
If desired, add a light garnish of toasted sesame seeds just before serving for extra texture.
For a vegan meal, combine it with rice, marinated tofu, and sautéed vegetables, using vegan dashi in the salad.
