Recipe Ingredients

You’ll need the following ingredients to make this Vegan Udon Soup:

vegan udon soup ingredients.
  • Udon noodles: You can find udon noodles in different forms – dried, fresh, or frozen – at your local Asian grocery stores. In this recipe, I opt for frozen udon noodles for their quick preparation, requiring just a few minutes of boiling.
  • Atsuage (deep-fried tofu), wakame seaweed, and scallions for the toppings. You can substitute atsuage with firm tofu. Also, I’ll introduce more topping variations in the later section.
  • Kombu dashi powder, salt, mirin, and soy sauce for vegan soup. Dashi, a type of soup stock, is the key ingredient in infusing your soup with savory flavors. To simplify the process, I recommend using store-bought kombu dashi powder. However, if it’s unavailable, you can prepare homemade kombu dashi as an alternative.
