Ramen, somen, udon… Japan is known for noodles. But one of the most classically Japanese noodle dishes is soba, which is typically made of a mix of buckwheat flour and white wheat flour, but can also be made with 100% buckwheat flour for gluten-free noodles. Soba noodles can be enjoyed either cold or hot, making it the perfect dish for any season. Served chilled, soba comes with a side of mentsuyu as a dipping sauce. It can also be served as a hot soba noodle soup, topped with tempura or kamaboko fish cake slices. With a characteristically nutty flavor and pleasant rustic texture, soba noodles taste delicious and also happen to be healthy.

Brief History of Soba Noodles

Soba is said to have originated from Central Asia as far back as and was brought to Japan from China sometime during the Jomon Period. The first records of soba noodles are from the Nara Period (710-794), a time when buckwheat was the food of commoners and was eaten to stave off famine. Soba noodles became rooted in the traditions of Japan; in particular, a Japanese New Year’s custom is to eat soba noodles on the evening of December 31st. Called “toshikoshi soba,” this annual tradition symbolizes a long and healthy life, as the noodles are kept long and slurped up. To try this custom for yourself, among other holiday traditions, join the Japanese New Year Food Tour in Shibuya.

Make Your Own Soba Noodles

Although it may look complicated, making your homemade soba noodles is not that hard at all, if you have the right tecnique. The ingredients are simple, just buckwheat flour, white wheat flour, and water. Combine the two types of flour and mix in the water until rough and crumbly, then knead it. The hardest part is rolling it out to an even thickness and cutting into even noodles.

Name That Soba

There are several different dishes where soba is the main star.

Here are a few variations of the most popular soba noodle dishes. 

  1. Zaru Soba
  2. Kake Soba
  3. Tempura Soba or Tensoba
  4. Kitsune Soba

1. Zaru Soba

Zaru soba, a type of cold soba noodles on a bamboo basket, with nori flakes

This is one of the simplest soba noodle dishes. It consists of cooked, rinsed, and chilled soba noodles that are served in a traditional bamboo basket, is known as zaru. Alongside the noodles, you have a small bowl of dipping sauce that’s made of soy sauce, mirin, and dashi. There are also other condiments and side dishes to spice up the meal, like fresh green onions, spicy wasabi, or thin slices of nori.

2. Kake Soba

Another popular way to enjoy soba noodles is as a hot dish. For kake soba, the soba noodles are boiled then drained. The hot broth (made with soy sauce, mirin, and dashi) is then poured over the noodles. Kake soba has a very mild flavor but is usually seasoned with spring onions for freshness, and at times fish cake may be included as well.

3. Tempura Soba or Tensoba

If you’re a fan of golden, deep-fried tempura, you’ll love tempura soba. This dish can be served either hot or cold. The hot version features the soba topped with tempura, such as seafood or vegetable tempura, whereas the cold version comes with a separate bowl of dipping sauce, where both the tempura and soba should be dipped as you eat them.

4. Kitsune Soba

Another popular soba noodle dish, kitsune soba also comes in two versions: hot and cold, where the soba is topped with aburaage, a thin and slightly sweet piece of fried tofu. 

Health Benefits of Soba Noodles and Buckwheat

1. Low in Calories

Compared to noodles made solely from white wheat, buckwheat is lower in calories, so it is a healthy substitute for other types of pasta. 

2. Gluten-Free

Contrary to its name, buckwheat is not actually a type of wheat, but it is actually composed of grain-like seeds. So, people with celiac disease or gluten intolerance can still enjoy soba noodles, as long as the soba is made with 100% buckwheat flour (some soba noodles are made of a mix of flours).

3. Good for Your Gut

The main ingredient in soba noodles, buckwheat flour is high in fiber. Dietary fiber keeps food moving through the digestive tract and contributes to a fuller, more satisfied feeling, reducing overeating. 

4. Plant Protein 

There are 6-8 grams of protein in a 2-ounce (dry) serving of soba. Protein is an essential component for building muscles and bones, and increases feelings of satiety, so you feel fuller for longer. And it is a plant protein, so vegetarians and vegans alike can enjoy soba noodles. Looking for more plant-based Japanese foods?
