What is Hijiki Seaweed Salad?

Hijiki seaweed is a brown seaweed commonly used in Japanese cuisine. It has a chewy texture and a mildly sweet, briny flavor. 

It’s a classic Japanese side dish made with hijiki seaweed simmered in sweet soy sauce, known for its unique texture and flavor. The salad is served cold or at room temperature and is known for its slightly sweet and savory taste. 

This hijiki seaweed salad is not only delicious but also rich in fiber, calcium, iron, and other minerals. You’ll often find this seaweed salad served on the side with meals to add flavor.

What Makes This Recipe Great?

Traditional recipes for this salad contain hijiki seaweed, edamame, carrots, and dried tofu (aburaage). Then these ingredients are simmered in a sweet sauce made with soy sauce, mirin, and sugar.

Because most dashi stock contains fish, this hijiki seaweed salad is not naturally vegan. So, to make our version vegan-friendly, we’re using vegan kombu dashi made with mushrooms instead of fish! And finally, to make it gluten-free, simply use gluten-free soy sauce (like Tamari).

This truly unique Japanese dish is the perfect complement to your favorite Asian entrees! 

Ingredients Notes

  • Dried Hijiki Seaweed: You can find all of the ingredients for this recipe at Asian grocery stores. Or, check the ethnic/Asian section of your grocery store. Hijiki comes dried.
  • Aburaage: This is dried, deep-fried tofu (you can also use Yuba). 
  • Neutral oil
  • Carrot 
  • Shelled edamame: You can also use frozen shelled edamame beans to save yourself time.
  • Vegan Dashi: For tons of umami flavour.
  • Mirin, which is Japanese seasoned rice vinegar and adds a nice sweetness to the sauce
  • Coconut sugar, though you can use organic cane sugar if you prefer. 
  • Soy sauce. Use gluten-free soy sauce or tamari. 

Step-by-Step Instructions

  1. Soak your dried hijiki seaweed in warm water in a bowl for about an hour until fully hydrated. Rinse and strain to remove excess water.
  2. Repeat with the aburaage, soaking in warm water until hydrated (about 5 minutes), then removing excess water.
  3. Heat oil in a pan over medium heat, and once hot, add the julienned carrots to the pan and sauté until bright and nicely cooked, about 2-3 minutes. Next, add aburaage and rehydrated hijiki and cook for another minute.
  4. Add dashi to the pan and bring to a boil. Lower heat to a simmer and add the remaining seasoning ingredients. Let cook, covered, for 15-20 minutes.
  5. Finally, add edamame, and then cook uncovered until the sauce reduces and thickens. Let cool completely before transferring to a jar to store.

Storage Suggestions
