📋 Ingredients
Here are the ingredients (amounts are in the recipe card below).
- Soba Noodles: Dried, fresh, or boiled soba noodles are available at grocery stores. I use dried soba noodles in this recipe. See more details below.
- Mentsuyu: It's a multipurpose noodle soup base with a savory flavor from dashi broth (Japanese soup stock), mirin, and soy sauce. I use store-bought one in this recipe. See more details below.
- Condiments: Green onions (or scallions, spring onions, and chives) and wasabi which is a pungent, spicy green-colored paste that is often served as a condiment with sushi.
- Shredded Nori seaweed (Kizami nori)
Soba Noodles
Soba noodles are popular Japanese noodles made by kneading buckwheat flour with water, stretching it thinly, and cutting it into thin strips. The light gray color is from buckwheat flour.
With their chewy texture and subtle taste, these noodles enhance any soup it's paired with.
You might be able to find dried, fresh, or frozen soba noodles at Asian grocery stores. Dried noodles are handy; I usually buy them and keep the stock in my pantry.
Mentsuyu (Noodle Soup Base)
Mentsuyu is a concentrated soup base used in Japanese cuisine to make various noodle soups, including udon and soba. It is made from a mixture of dashi (soup broth), soy sauce, and mirin (sweet rice wine).
For those short on time, using bottled mentsuyu is easiest. I always keep one in my fridge as this versatile sauce is perfect for cooking Japanese dishes. I use store-bought one in this recipe.
The instructions on the bottle will usually specify how much water to add, as the ratio can vary depending on the product.

Helpful tips
- Mentsuyu - The instructions on the bottle will usually specify how much water to add, as the ratio can vary depending on the product.
- Soba noodle boiling time - Dried noodles take 4-7 minutes, fresh noodles take 2-3 minutes, and boiled noodles take 30 seconds-1 minute. The cooking time can vary depending on the type and brand of soba noodles.
Vegan Adaptable
Mentsuyu is typically made from katsuobushi (dried bonito flakes), which is unsuitable for a vegan diet.
However, you can substitute it with dried shiitake mushrooms and kombu seaweed to make a vegan-friendly sauce, which can be a good alternative for those following a vegan diet or who prefer plant-based options.

How to Serve Zaru Soba
When eating at a Japanese restaurant, zaru soba is typically served on a bamboo strainer (zaru) or bamboo basket, with dipping sauce and condiments on the side.
The bamboo strainer drains any excess water from the noodles and prevents them from becoming soggy. It helps to keep the soba noodles firm and chewy, allowing you to enjoy their texture and flavor to the fullest.
Additionally, the strainer adds a traditional touch to the dish's presentation, making it an attractive and appealing option for serving. (The strainer in the photo is made of plastic, not bamboo.)
How to eat Zaru Soba
To start, try the zaru soba with just the noodles and dipping sauce. You can then experiment with adding condiments to the sauce to adjust the flavor to your liking. Whether to add them little by little or all at once is a matter of personal preference.
To eat zaru soba, use chopsticks (see how to hold chopsticks) to pick up a few noodles and dip them into the sauce halfway, making sure not to fully submerge them as the sauce overpowers the soba noodles' flavor.
Next, lift the noodles out of the sauce and slurp them up to savor their chewy texture, be careful as the sauce might splatter (if you are comfortable slurping, though).
About slurping noodles
If you come from a culture where slurping food is uncommon, slurping noodles may feel strange. However, if you want to experience zaru soba's deliciousness fully, come to Japan and slurp noodles with us! It's a fun and authentic way to enjoy this popular Japanese dish and immerse yourself in the local culture!
Sobayu
When dining at soba restaurants in Japan, it is common to be served sobayu after finishing the dish. Sobayu is the water used to cook soba noodles, similar to pasta water. You can drink sobayu like tea or add it to the remaining dipping sauce and drink.
Sobayu is rich in nutrients such as vitamin B1 and rutin, also found in soba noodles. Consuming sobayu allows you to enjoy the nutritional benefits of soba noodles and their unique flavor. Thus, sobayu is a great way to experience the full benefits of soba noodles.
Variations of Condiments
Experimenting with different condiments is a great way to add extra flavor to your liking. Some popular condiments for zaru soba include:
- Green onion, spring onion - adds a fresh taste.
- Grated ginger - adds a zesty and aromatic flavor.
- Daikon oroshi (Grated Japanese radish) - adds a fresh and slightly tangy flavor.
- Wasabi - adds a spicy kick to the sauce.
- Shichimi togarashi (Japanese seven-spice blend) - adds a spicy and slightly smoky flavor.
- Ponzu (citrus-based sauce) - adds a tart and tangy flavor.
- Sesame seeds - add a nutty flavor and added texture.
Feel free to experiment and find the combination that you enjoy the most!
