Somen Noodle Soup: the Regional Food of Nara

Somen noodle soup is called Nyumen (にゅうめん, also written as 煮麺, which literary means “boiled noodles” in kanji characters) in Japan, and it’s a regional dish of Nara prefecture. The Yamato region in Nara prefecture is said to be the birthplace of the famous Tenobe somen (手延素麺). Their somen noodles are known for their finest strands and superior springy texture.

What Are Somen Noodles?

In case you have never heard of somen noodles, they are made of wheat flour, salt, and water. Simple yet delicious, the noodles are super thin and take almost no time to cook. On their own, somen noodles are mild, but they have the ability to absorb flavor from whatever they’re served with. While cold somen is common throughout Japan, hot somen noodle soup or nyumen is enjoyed especially in the fall and winter months in the Nara region. Nyumen consists of a light dashi-based soup and separately-boiled somen noodles. It’s often served with shiitake mushrooms, eggplants, dried shrimp, yuba (tofu skin), and green vegetables. I love that they are light so they don’t weigh me down, while still bringing plenty of flavor and character to the table.

How to Cook Somen Noodle Soup

Cooking Tips

Broth

I included two ways to make the broth in the recipe. The first method involves making the broth from scratch, using dashi and seasonings. The second one is a short-cut method by using mentsuyu (tsuyu)—noodle soup base. Double up the broth if you plan to eat it again in the same week. Wish to make vegan broth? Use Vegan Dashi!

Somen Noodles

Always use a big pot of water to cook the noodles. Remove all the wrapping of the noodles. Somen noodles cook fast, only 1.5 to 2 minutes! Therefore, you need to act fast. All the noodles should be added to the boiling water at the same time. After draining the water, wash the noodles as if you are washing clothes by kneading or gently massaging. This is the proper way! Somen noodles use oil to achieve their thinness, so we need to make sure to remove the oil.

Toppings

Always start cooking from hard vegetables or dense parts of the vegetable(s)—like the bottom part of bok choy or napa cabbage. If you like to add meat or seafood, don’t forget to skim the broth with a fine-mesh skimmer so the broth will stay clean and clear. When you add beaten eggs, make sure the broth is simmering so the eggs will become fluffy.

Toppings and Seasoning Ideas

This recipe makes an excellent base soup that can be spruced up with any combination of protein, vegetables, or seasonings! Protein Toppings

As you can see, the options are endless when comes to making somen noodle soup. This is exactly why I love using this soup as a comforting, healthy meal to keep my family nourished. Feel free to make a big batch of the broth so you can enjoy it throughout the week!
