Everyone Loves Japanese Noodles!

Forever iconic, there’s been a long love affair with noodles not only in Japan but across the world. While everyone loves ramen, here, we are taking a closer look at two of Japan’s other notorious noodles – Soba and Udon. From beautiful hot broth to chilled noodles with dipping sauce, poached eggs, and creamy sauces – there are so many intricate Japanese dishes that cement our adoration of the humble noodle.

It’s believed that Udon first showed up on the Japanese foodie scene back in the 700’s when it made its way over from China. It didn’t gain mouthwatering momentum until the 1600s though. Sobs started spiraling in popularity around the 1700s. Now, practically any Japanese restaurant you go to will probably have Udon or Soba on the list. Whether chowing down on Soba Maki or going crazy for Kake Udon, here’s all you need to know about these two types of noodles - Soba vs Udon.


The Difference Between Soba & Udon

Flour – Udon uses wheat flour for that dense and dreamy thick finish and chewy texture whereas Soba celebrates buckwheat flour with its slightly grainier texture.

Color – Udon rocks that glossy white coloring whereas Soba is darker (often a brown color or grey).

Taste – Udon is the milder noodle which makes it pretty versatile when it comes to adding it to your favorite Japanese dish. Soba has its own taste which is a little nutty. This is why Soba is often best served in simple light dishes that don’t go wild on rich flavors.

Thickness – Udon noodles come in different varieties but they tend to be thicker and wider than Soba.


Which is Healthier, Udon or Soba?

With its wholegrain like appearance and buckwheat heavy base, Soba is the healthier choice when it comes to your Asian noodle game. This is because buckwheat is lower in carbohydrates and lower in calories so it’s a good choice for those trying to cut back. Buckwheat also has plenty of health benefit boosting properties and is chock full of nutrients and good grains to keep your energy levels riding high. For those who are looking for gluten-free solutions, there are lots of Soba varieties lining the grocery stores without gluten. That’s not to say that Udon is unhealthy. In fact, this noodle is super easy on the stomach and an awesome ingredient for those who adore clean and easy eating.


Soba Noodles
