How to Make the Recipe

Let’s get cooking! Making zaru soba is a breeze. Here’s how:

  1. First things first, take 3g of kombu and place it into a pan with 200ml of water. Let it infuse for a relaxing 30 minutes. Trust me, this step definitely enhances the flavor!
  2. After the infusion, add the soy sauce and mirin to the pan and bring the mixture to a gentle boil. Your kitchen is about to smell divine!
  3. Next, toss in 15g of bonito flakes, give it a stir, then take the pan off the heat. Let the sauce cool down to room temperature. Once it’s cool, pour the mixture through a fine sieve into a bowl. Chill this in the fridge until you’re ready to serve.
  4. Now, follow the package instructions to boil the soba noodles. Remember to reserve some of that cooking water—it’s liquid gold! Rinse the noodles under cold water, and be sure to drain them properly.
  5. To serve, add some sliced spring onions and a dab of wasabi to your chilled dipping sauce. Take your chopsticks, grab a nice portion of noodles, dip half of it in that luscious sauce, and don’t forget to slurp! You’ll want to really savor each bite. Once you finish the noodles, heat the reserved cooking water and mix it with the leftover sauce for a soothing soup that you can sip on. It’s traditional and, I promise, it’s so good!

Pro Tips for Making This Recipe

  • Be careful not to overboil your soba noodles. Just follow the package instructions, and your noodles will turn out perfectly chewy.
  • If you can’t find bonito flakes, you can use a similar dried fish product or even skip it entirely. The kombu and soy sauce alone make a lovely base!
  • Want to step it up? Top your soba with some tempura vegetables for added crunch and flavor.

How to Serve

Zaru soba pairs beautifully with a variety of sides and drinks. A crisp cucumber salad or light miso soup complements it perfectly. It’s a fantastic dish for summer gatherings or a cozy dinner at home. For drinks, I love serving it with chilled sake or a refreshing iced tea. Pro tip: to make your presentation pop, arrange your noodles in a nest-like shape and sprinkle with sesame seeds!

Make Ahead and Storage

This dish is fabulous for meal prep! Leftovers can be stored in an airtight container in the fridge for up to 3 days. While it’s best enjoyed fresh, the flavors in the dipping sauce only deepen over time, making it slightly better the next day. If you want to freeze the noodles, cook them slightly less than al dente and freeze in individual portions. When you’re ready to eat, just reheat briefly under hot water.

FAQ

Can I make this gluten-free?

Absolutely! Look for gluten-free soba noodles made from 100% buckwheat. They will give a great flavor even without gluten!

What if I don’t have mirin?

If you don’t have mirin, you can use a mix of equal parts sugar and white wine or even apple cider vinegar. It won’t be exactly the same, but it’ll still be delicious.

Can I use an air fryer or slow cooker instead?

This recipe is best made on the stove, but you can definitely use an air fryer to make tempura vegetables alongside your zaru soba. Just be mindful of your cooking times!

I hope this dish brings as much joy to your table as it does to mine. Zaru soba is a delightful blend of flavors that can instantly transport you to a peaceful summer afternoon, just like it did for me. Let me know how it turns out — I’d love to hear from you!
