What Is Miso?

Does miso seem mysterious to you? It was seriously strange to me for a long time because I didn’t know what it was and how to handle it. Now, I love it, and I want you to love it, too!

Miso is a mixture of mold (the good kind!), water, a little bit of salt, and cooked soybeans (sometimes with a grain, like rice or barley) that is fermented in crocks from a week up to an entire year. The mold, Aspergillus Oryzea, is called Koji in Japanese. Think of it as being similar to the way blue cheese is created.

This inscrutable ingredient gives a powerful punch to any soup, stew, or even salad dressing. Add a small teaspoon of miso to any liquid or broth and you’ll be blown away by its bold new flavor. Keep a container of miso in the fridge to have on hand for any situations that need a salty spark!

How To Use Soba Noodles

Soba noodles, a staple of Japanese cuisine, are thin, light brown to grayish-brown noodles made from buckwheat flour. Combined with a little water, an accomplished Japanese artisan traditionally rolls the dough out very thin and cuts it into long, thin strips, forming the characteristic soba noodles. Sometimes whole wheat flour is added to keep the noodles from noticeably breaking down.

It’s super important to stir your soba noodles when cooking. The noodles have a tendency to become a mushy mass if left unattended. Stay near the stove and do your best to prevent the noodles from pressing together.

Any soggy, overcooked soba can also be revived if you quickly rinse them in cold water and submerge them for a moment in a little ice water. These noodles have a wonderful texture when cooked well and they have the most satisfying slippery sensation when enjoying your soup. Well worth the time and effort.

What Is Nori?

If nori is unknown to you, here’s what it is: the Japanese name for an edible seaweed used in cooking, especially in the making of sushi. This type of seaweed comes from the red algae genus, Pyropia. It’s pronounced, “naw-ree.”

This glorious, dark green ingredient is made in almost the same way that paper is made, by shredding the seaweed, pressing out the excess water, and dehydrating on a special screen. The texture is super thin, light, and smooth. Nori usually comes in a packet of 10 sheets (sometimes toasted) and can be found in the Asian section of the grocery store.

Nori adds a lovely umami flavor which is slightly sweet and salty but not at all strong or fishy. It offers a host of vitamins and minerals such as iodine, vitamins A & C, potassium, magnesium, calcium, iron, and zinc. Sometimes labeled as “laver” seaweed, it is a staple in this miso noodle soup.

Top Tips

  • Don’t be too quick to add miso. To preserve the full flavor and nutritional value of miso, add it towards the end of cooking. Avoid boiling the miso paste, as high heat can diminish its taste and beneficial enzymes.
  • Stir the soba noodles. Soba noodles cook quickly and have a tendency to stick together if left unattended. Make sure to stir them while they cook to keep them from clumping together.

Vary Your Vegetables

Feel free to use a variety of vegetables in this soup. If you have some kale that’s looking pretty sad, chop it up and add that! If you don’t have any brilliant green broccoli on hand, you can always substitute a cup of crunchy cauliflower.

Other super tasty options include:

  • Bok choy
  • Snow peas or sugar snap peas
  • Edamame
  • Mung bean sprouts
  • Water chestnuts
  • Purple cabbage

To keep this soup light and easily slurpable, it’s best to keep all of the vegetables thinly sliced and as delicate as possible. Cutting your vegetables on a mandolin might help or using a sharp knife. Prepping your vegetables the night before will make cooking even easier the next day.

Storing Your Savory Vegan Miso Noodle Soup

Any extra vegan miso soup with noodles can be simply stored in a container in the fridge for up to 5 days. If your soup has lost some of its liquid and is more like a stew, you can easily add a little extra water or vegetable broth before heating.

If you don’t want to lose any of the savory, salty flavors, mix up another small batch of the miso mixture and add to a saucepan with the remainder of the soup. For the miso mixture, add 2 tbsp of miso to ½ cup water or vegetable broth and whisk well. Heat on medium-low for 2-5 minutes, making sure the soup does not come to a boil.

Leftovers can also be kept frozen for up to 6 months in a freezer-safe, covered container. Alternately, you can spoon the soup into empty ice cube trays and store the “soup cubes” in a freezer bag until ready to use.

Ten-minute Miso Noodle Soup

Miso is a traditional food that’s been consumed in Japan and China for thousands of years. Made from fermented soybeans, the salty paste can be used in a variety of recipes, but it’s most commonly used in soup, which is widely consumed for breakfast in Japan to get one’s day off to a healthy start. No matter what time of the day you choose to eat it, miso soup is delicious and nourishing. Be mindful though—many restaurants add bonito—dried fish flakes—to their miso soup. This ten-minute Miso Soup offers a slightly different twist on the traditional miso soup and you can customize it with your favorite vegetables.
