What is Zaru Soba?

Zaru Soba is easily one of my favorite meals to have in the summertime as they are simple to prepare, healthy, and best of all, loaded with incredible umami flavors to complement the ice-cold noodles.

This soba recipe is third on the cold noodle series I am sharing with you to enjoy on a hot summer day and one that I make the most often due to its alluring flavors and easy prep.

Soba noodles are known to be healthier than other alternatives as it is made with a base of buckwheat flour, resulting in fewer calories and more nutrients such as Vitamin B, various minerals, and fiber.

It’s also gluten-free and tastes incredible with a nutty flavor and a wholesome texture.

If you’ve been following my blog awhile you’d know that my obsession with noodles is indisputable, and this is a great way to satisfy that noodle craving without taking on the extra calories.

Although there are many different ways to prepare cold soba noodles, the dish that I am sharing with you today is known as Zaru Soba (ざるそば) in Japan.

This is the most classic way to serve soba noodles in dipping them in a rich and flavorful Mentsuyu sauce, which can be put together in minutes using this easy recipe.

Although Mentusyu is traditionally made with homemade dashi stock and a long list of ingredients, we will be simplifying the process today as usual but without any compromise to the taste.

Best of all, the soba dipping sauce is good for up to 2 weeks in the fridge, making it the ultimate make-ahead meal to enjoy during the summertime.

What do I need to make Zaru Soba?

This easy soba recipe calls for a seamless two-step preparation of cooking the noodles and making the dipping sauce. Here is everything you’ll need to make this delicious summer meal:

• Soba noodles: to be cooked, chilled and served alongside your Tsuyu sauce. These noodles are sold pre-portioned and only take 3-4 minutes to cook in boiling water, to be strained and rinsed under ice-cold water prior to serving.
• Dashi: for the base stock. This is the backbone of many Japanese dishes, and can be prepared easily with instant soup stock, which works in a similar fashion as chicken bouillon powder.
  • To prepare your dashi, simply mix the powder into water and it’s ready to go! For 1 cup of water, you will need to mix in about 1/2 tsp of dashi powder.
  • Please feel free to use homemade stock as well if you prefer, but this method is a true life-saver for the busy days, without compromising the flavor.
  • Another alternative is to use low-sodium chicken stock, or a 2:1 ratio of regular chicken stock and water. To prepare for this recipe, you’ll need to mix 2/3 cup of chicken stock with 1/3 cup water.
• Soy sauce, mirin, and sugar: to season the dipping sauce.

How do I serve Zaru Soba?

There are many different ways to serve Zaru Soba, but my favorite way is to garnish the noodles with some shredded nori, microgreens, and sesame seeds.

You can also dress your sauce with minced daikon, quail egg yolk, and a large handful of chopped green onion if you prefer.

Here is a list of popular toppings that you can add to your tsuyu dipping sauce:

• Chopped green onions: or scallions.
• Shredded nori: you can purchase pre-shredded nori, or use a pair of scissors to snip them into silvers.
• Wasabi: fresh or store-bought will both work.
• Grated daikon or ginger: shaved in a fine grater and squeezed of excess liquid
• Egg yolk or poached egg: quail or regular-sized
• Tempura: vegetable or shrimp

The best way to serve these soba noodles for a crowd is to serve the noodles and dipping sauce individually, and have the variety of toppings centered at the table for guests to dress their sauce to their liking!

Zaru Soba is quick & easy to prepare and makes for a fun activity for your loved ones to enjoy together, which makes it a popular choice for a shared meal during the summertime.
