30-Minute Asian Soba Noodle Soup


30-Minute Asian Soba Noodle Soup

30 minute soup? With veggies and noodles? And it’s all in one pot? Yup. That’s exactly what’s going on here today. This is a 30 minute soba noodle soup recipe and it’s about to be your new weeknight go-to!

Two things before we get to the business of making soup: 1) this soba noodle soup is an older recipe. We originally posted it in 2014. I took new pictures and added in some updates to make the recipe easier to follow. And 2) This soup is 100% Clark’s brainchild. I said “I want soup” and he said “boom.” 20 minutes later, we were sitting down to dinner. Not too shabby. 

As the recipe title implies, this soup is easy BUT more importantly, it seriously takes only 30 minutes to make. AND it’s all in one pot. I mean, hello guys. This is dinner magic and it’s about to make your life so much happier!

Asian Soba Noodle Soup

I love the tender carrots and the bok choy slivers that soak up the flavor of the soup. It has the slightest hint of spice – just enough, but not too much.

    I just made this soup and and it was amazing! It was my first time cooking with soba noodles, and tamari sauce, and it turned out great! Me and my boyfriend loved it! :)

      OMG yes! So glad you liked the recipe. This soup is definitely amazing!

    I noticed you pre-cook the soba. It seems to me that there should be no reason to do that if you are putting the soba into boiling broth for 15 minutes. Wouldn’t that cook the noodles?

    • thefitchen

      Hi Mark! You could most certainly try cooking the noodles into the broth. My reason for boiling separately was to keep the noodles from absorbing too much of the soup itself. Let me know how it works!

      Hi Mark, I know this post is responding to a few year old post but I just came across this recipe and wondered the same thing about not pre-cooking the noodles. Well, I just made it tonight and found out why it’s better to pre-cook the noodles. The starch from the noodles made the broth too thick. It tasted good but it would have been much better with a thinner broth. I’m trying it again by cooking the noodles separate. :)

        Thanks for the feedback, Rose! You’re exactly right. Pre-cooking the noodles prevents the soup from getting too starchy. :)

          But I think that he was saying that the broth is too starchy IF you do not pre-cook the noodles as you recommend in your recipe. So he is saying that your way of doing it in your recipe keeps the broth the right consistency, not too thick.

    Hi!! I just made this and it was super super good! I added frozen corn and peas, and substituted bok choy for romaine lettuce since I did not have bok choy on hand. I also subbed tamari sauce with soy sauce since I didn’t have that either. I will definitely be making this again and again, thank you!! ^_^

      Hi Anna! Thanks for letting us know – so glad you liked this soup! Great ideas on the substitutions… this is definitely a versatile recipe. :)

    Loved the recipe, for an extra OOOOMPH…I added 2 tbsps of rice vinegar and 1 tbsp of chili sauce. Thank you for the recipe….my son loved it too!

      Hi Eva –

      You’re a brave one! I’m always hesitant to add spice, but that chili sauce sounds like a fantastic addition. Glad you enjoyed!

    Hi! I made this soup today and it was delicious. Thank you very much for posting the recipe two years ago! ;) I didn’t think there was enough liquid, though. I used 3 cups of chicken stock and it was more saucy (but watery) than soupy. I came back here to see if anyone else commented the same, but it looks like it’s just me! Maybe because I added an extra carrot? Still fantastic, though! I will just add some water to it next time. I also used scallions instead of onion and I didn’t have cayenne, so I used paprika and chili flakes. :)

      Thanks for commenting Jacqueline! So glad you liked the soup. :) Hopefully the consistency turns out a little more to your liking next time!

        Hi Chris! I’m sorry the recipe didn’t turn out for you. We just retested this recipe recently and it turned out just fine. I’m not sure what went wrong for you!

    I made this tonight as I have been desperately searching for a simple Asian soup recipe! This was delicious!
    I added baked tofu and broccoli to the soup along with some green onion on top and it was amazing. I did omit the salt just because I didn’t think it needed it.

    I think next time I will not simmer the veggies as long because i tend to like them a little crunchier (personal preference!). Thank you so much for this recipe! Will make it again and especially great for anyone coming down with a cold (me).

    Will be making this again!

      Hi Anne –

      So glad you like this soup! Adding tofu and broccoli is a great idea – I bet that made it even better. :) Thanks for your comment!

    Tha’ts alot of sodium. Is it really necessary?

    • thefitchen
      July 24, 2015

      If you need to cut down on the amount of sodium, you could use reduced sodium tamari or soy sauce and omit the teaspoon of sea salt. Hope that helps!

    I’m going to tweak the recipe a bit as I hate onions (but feel some mushrooms would be awesome). Do soba noodles reheat well?

    • thefitchen
      September 8, 2014

      Totally understandable haha! Mushrooms would be killer in this soup – and soba noodles reheat well in this soup. :)

    Most soba noodles on the market are a mix of both buckwheat and regular wheat, just fyi. If you want 100% buckwheat only noodles, I have only seen them sold online, although I’m sure there are some health food stores that sell them. Just a heads up!

    • thefitchen
      July 30, 2014

      We ended up finding ours at a small health food store in Greenwood, IN of all places! You can definitely find them online – we have to do that with a specific kind of rice noodles that we love! Have you had any luck finding GF soba in stores?

      • Erica
        January 29, 2015

        I’ve found 100% buckwheat soba noodles at Whole Foods. There are several brands on the market now.

          Glad to hear that you found them! I’ve noticed lots of new options popping up, too. Good news!

    I made this soup last night, it was my first time using soba noodles. I absolutely loved it!! So light, so many flavors. The veggie choice is perfect in this soup although I may experiment with bean sprouts and maybe some cilantro and a squeeze of lime. Sounds like pho!! Thanks for sharing, I will be making this forever.

    • thefitchen
      June 18, 2014

      Mmm – bean sprouts! That would be perfect in this soup! I’ll DEFINITELY be adding those the next time we make a pot. So glad you enjoyed!

    Hello! This looks amazing! I don’t have any bok choy on hand, do you have any suggestions of substitutes? Thank you :)

    • thefitchen
      May 20, 2014

      Cabbage is a good substitute for bok choy. Celery would work, too. Let me know what you use!

  • Stephen
    January 27, 2014

    My gf can’t eat onions or garlic. I could probably put a bit in and it wouldn’t hurt, but do you have anything else I could add instead to keep it hearty?

    • thefitchen
      January 28, 2014

      I would suggest adding more bok choy and maybe even 1/2 to 1 cup of chopped celery. Let us know what works!

      It hits the spot! And soba noodles are going to become a common item around here. :)

          Hi Diane –

      • mykus

        Did you add the noodles back to the soup and veggies before or after the 15 min. simmer?

        • thefitchen
          August 10, 2015

          You’ll add the noodles and veggies before the final 15 minute simmer. :)
