📋 Ingredients

Here are the ingredients (amounts are in the recipe card below).

Vegan soba noodle soup ingredients list.
  • Soba noodles – Soba noodles are chewy buckwheat noodles made by kneading buckwheat flour with water, stretching it out thinly, and cutting it into thin strips. 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.
