Vegan soba noodle soup ingredients list.
  • Soba noodles – Dried, fresh, or frozen soba noodles are available at grocery stores. I use fresh soba noodles in this recipe. Learn more Japanese noodles in 3 Popular Japanese Noodles Explained.
  • Choose from a variety of toppings, including scallions (green onions), spinach, aburaage (deep-fried thin tofu), wakame seaweed, tororo kombu (seasoned seaweed), and tenkasu (crunchy tempura bits). Opt for simplicity with one or two toppings, or explore the following list for additional variations!
  • Dashi, salt, mirin, and soy sauce for dashi-based broth. Dashi stock is the key ingredient bringing rich umami to Japanese cooking (learn more in What is dashi). It’s typically made from bonito flakes, but I use store-bought kombu dashi powder, which is vegan dashi, in this recipe.
