Soba Noodles Tofu Soup with Limes, Carrots and Kale

Light and flavorsome vegan soba noodle soup to keep you warm on a rainy day. An easy lunch that leaves you satisfied and full of energy for the rest of the day. And ready to serve in less than 30 minutes!

I’ve been making this little soup with tofu and vegetables for years now. Every few months or so. Actually every time I manage to buy soba noodles somewhere… It has become a habit: soba noodles = this soup.

Why? It’s quick and easy, it’s super healthy and light and it just makes me happy… 🙂

Soba Noodles Tofu Soup with Limes, Carrots and Kale

What do you need?

  • Soba noodles
  • Tofu – firm tofu. You can use plain or something more interesting like smoked, peanut, basil, or tomato tofu. There are so many options, and I’ve been through many of them.
  • Miso – white miso, which is actually quite orange in color.
  • Vegetables: onion, green onions, garlic, carrots, and kale. You can change the veggies according to taste or what you have in the fridge. I often use spinach instead of kale because it is easier to get. If using spinach only add it to the soup during the last minute of the cooking time, it should only wilt.
  • Frozen spinach or kale can be used instead.

How to make?

This vegan noodles soup was one of the first recipes I’ve posted on the blog, many years ago. This is the third or fourth update and each time I’ve changed the recipe a little. Not because it was not good. As mentioned above, I am quite passionate about this recipe, but because each change actually made the soup even better.

  • Fry the cubed and spiced tofu in a little oil.
  • Cook the onions and the carrots.
  • Add broth and kale. Cook shortly.
  • Cook the soba noodles separately.
  • Mix miso with some of the hot liquid. Pour into the pot. Season.
  • Assemble the bowls: grated garlic + green onion rings + noodles + tofu cubes + broth with veggies + lime wedges.

Good for your kids Adina, shows they are making progress. And what a delicious soup. I like using kale when I can. I have only cooked with tofu a few times, so glad to be learning here. Wishing you a beautiful 2018 my friend. xo
