Soup With Soba Noodles
If I had to pick a favorite noodle, it would probably be Japanese soba, or buckwheat noodles.
There are so many reasons why I love soba—the smooth, slippery texture, the subtle nuttiness of buckwheat flour, and how it’s just as good hot in a comforting broth as it is cold with a dipping sauce. Another reason? It’s so easy to prepare.
Soba usually comes in individual serving bundles, so there’s no need to measure, soak, or rinse. Just peel off the paper wrapper, drop the noodles into boiling water, and in a few minutes, they’re ready to serve.
This 15-minute soba noodle soup is the easiest way to get a quick, satisfying meal on the table. It really does take just 15 minutes, and you get a healthy, delicious bowl of soba in a flavorful broth.If you’re looking for more easy and delicious meals, check out my Tomyum Noodle Soup and Fried Rice too!

- Better than takeout. Fresh, homemade, and way more flavorful than anything store-bought. Plus, you know exactly what’s in it!
Ingredients You’ll Need
- Soba noodles – Traditional buckwheat soba is best, but if you don’t have it, whole wheat spaghetti, rice noodles, or even udon will work.
- Water
- Bonito-flavored soup base – If you don’t have this, mix low-sodium soy sauce with a little dashi powder or fish sauce. Light chicken or vegetable broth works too.
- Buna shimeji mushrooms – Shiitake, enoki, or even cremini mushrooms are good substitutes.
- Baby bok choy – Spinach or napa cabbage can work as alternatives.
- Hard-boiled egg
- White sesame
- Scallions – If you don’t have scallions, chives or thinly sliced leeks work just as well.

How To Make Soba Noodle Soup
Bring a pot of water to a boil, then toss in the soba noodles. Let them cook for about 5 minutes until they’re just right—not too soft, not too firm. Once they’re done, drain them and set them aside in a bowl.
While the noodles are resting, grab another pot and bring 1 1/2 cups of water to a boil. Stir in the Mizkan bonito-flavored soup base, then toss in the mushrooms and baby bok choy. Let them simmer for about a minute—just until they’re nice and tender.
Place the egg right on top of the soba noodles, then pour that flavorful soup all over. Finish it off with a sprinkle of sesame seeds and chopped scallions, and you’re good to go!
Frequently Asked Questions
You can swap it with a mix of soy sauce and a stock cube (chicken or dashi works best). Start with 1 tablespoon of soy sauce and half a stock cube, then adjust to taste. Just a heads-up—it won’t have the same depth of flavor as the bonito base, but it’ll still work!

Hi,I posted about Gold Dusted potatoes versus Yukon Gold Potatoes and you didn’t know the difference between the two.I found out that Gold Dusted potatoes are a combined Yukon Gold Potato and Idaho .Not as Creamy and Delicious as Yukon Gold.If it’s possible can you please send some recipes using Yukon Gold Potatoes?I have many but this site is special because you have shared many delicious creative recipes.Thank you
Thanks!
This is awesome. You have inspired me to try other soup bases….:).
Though I modified the recipe slightly, I stir fried chicken to 75%, set aside and added it later when adding the broth, then stir fried garlic and ginger and added shiitake mushrooms. I also used chicken broth and Mung bean for garnish and a super-food punch. Was fantastic and easy. You really are doing a great job, thanks.
Thanks for your support.
Thank you for this recipe! I’ve been making it for breakfast lately, with multiple variations, and I’m really enjoying it. It is the perfect start to a chilly winter day!
Yes!
I roasted tofu in a siracha-miso-soy marinade and added to the soup in place of egg. DELICIOUS!!!
Ali -yum sounds delicious!
I am trying to find the Mizkan online and it seems it has corn syrup in the ingredients… do you know of a brand that doesn’t have corn syrup or a supstitite by chance? Thanks :)
Sorry but I don’t really know.
I tried this today and love how simple and fast it is! I added togarashi and garlic to the broth and I used edamame because I didn’t have any book Choy or mushrooms. I will definitely make this again with those veggies. This is a good base recipe, I think I may add tofu or chicken next time, although it isn’t really needed because the dish is so filling
Yes Randiah. You can do a lot of things with this basic soba noodle soup!
As Tony the tiger would say… “it’s ? Grrrrate!!!!”
The soup was great but Mizkan has MSG! and TONS of salt. YUCK. I didn’t check the label. Afraid I can’t make it again.
Carol, you can buy the green label Mizkan with no MSG and less sodium.
What brand of soba noodles did you use? Thx.
No particular brand.
if don`t have bonito flavoured soup base, can I use stock cube/ soya sauce instead?
I think so but taste is not as good.
Hello! I recently discovered your webbie and i’ve been making a lot your japanese recipes using the Mizkan shortcuts. I made this today and it was pretty good – flavorful but not overbearing. I think I’ll add a little sesame oil/spice/extra bonito flavored based as it was a bit light. Thanks for sharing these easy recipes!
Susan – that’s great, yes, add anything you like to jazz up the taste. You can also add Japanese 7 spices (togarashi)
