Coconut-Lemongrass Soup with Buckwheat Noodles (Tom Ka)

This post is a small homage to my recent travel to Thailand. I was so lucky to be able to spend a few days after Christmas and the New Years Eve in Bangkok. It was a truly great trip and I had the chance to catch up with family and friends and also to get lots of recipe inspiration from this trip. I will be posting recipes about some new Thai food discoveries in a next post :-)

Today, I wanted to share with you a soup which is inspired by the very typical and iconic Thai dish “Tom Ka Gai”. The dish’s name actually describes it really well, it is a soup (“Tom”) with “Ka” (= galangal) and chicken (“Gai”). The typical ingredients for this soup are lemongrass, galangal (root, similar to ginger) and of course, creamy coconut milk. Due to some ingredients limitations and because I also omitted the chicken this time, I had to make quite some tweaks to the original recipe. I also wanted to make it a nutritious and healthy weekday meal and added some buckwheat noodles to it.

This delicious and creamy soup contains following Superfoods:

  • Buckwheat
  • Tomatoes

Ingredients: (for 2 portions)

  • 1 can of coconut milk (about 14 oz)
  • 2 stems of fresh lemongrass (ideally, I was not able to find it in Miami though, so I used 2 tbsp of organic lemongrass paste instead – see picture below)
  • 1 small chunk of ginger, cut into pieces (or if you can find galangal, even better, add that instead of the ginger)
  • 1/2 lime, the freshly squeezed juice
  • 2 tbsp organic coconut palm sugar (healthy alternative to refined sugar!)
  • A handful of cherry tomatoes (use the whole tomato, don’t cut them)
  • A handful of fresh mushroom (cut into small pieces)
  • A handful of mini corn (if you can find fresh ones, the better, if not, from the can, rinsed, works too – cut into small pieces)
  • Cooked buckwheat noodles (amount depends on your level of hungriness πŸ˜‰ )
  • A handful of fresh cilantro
  • Salt & pepper to taste



  • In a pan, heat up the coconut milk, in case you were able to find fresh lemongrass stems, add them to the simmering coconut milk for about 20 – 30 minutes to bring out the flavor, add the ginger pieces too (respectively galangal if you could find it), remove them after you extracted the flavor
  • In case you were not able to find the fresh lemongrass, no worries, add the paste and the ginger (galangal) pieces
  • For both cases, add as a second step the tomatoes, the chopped mushroom and the young mini corn
  • When the vegetables are cooked tender, add the palm sugar and season with salt and pepper to taste, add 1 tbsp of chopped cilantro to the soup as well, keep the rest to garnish
  • Add the cooked buckwheat noodles shortly before serving, so they don’t become soggy, garnish with some cilantro
  • Enjoy! πŸ˜‰

This is a super easy and fast recipe – ideal for weekday dinners! In case you want to serve this as an appetizer, just don’t add the buckwheat noodles, to make it “lighter”.

    Ah – lemongrass in a tube. I never thought to look with the herb pastes – I can’t find it in the jars in any Calgary store! I’m such a fan of buckwheat noodles too so look forward to trying this out. Thank you for your kind words! But gosh, YOUR photos are outstanding! I’ve been checking out your blog periodically for a loong time!

      Thank you so much dear!! I have been following your blog for a while too! πŸ˜‰ I read that days are really short where you live, I find it also really hard to take pictures without natural light, luckily days here in Miami are a bit longer most of the time…Keep up the great work! I am amazed how you still manage to get this beautiful lighting for your food. Looking forward to read more πŸ˜‰ Hopefully you will find the lemongrass somewhere in your supermarket! πŸ˜‰ Keep me posted in case you try the recipe!

    How delicious! I love the bright flavours of Thai food- lemongrass and ginger yum!
    I went to Thailand nearly 10 years ago and loved it :)

    • superfoodista says

      Thank you so much Emma! πŸ˜‰ I am also in love with Thailand – and definitely Thai food!! When I miss my second home (= Bangkok) a lot, I make myself a nice plate of yummy, flavorful Thai food! πŸ˜‰ Thanks for stopping by year.

      Thank you so much Afra for this kind comment! πŸ˜‰ I am a soup lover! πŸ˜‰ But yes, this dish should work for everyone, it’s basically a meal with the buckwheat noodles, and it’s very creamy, so it’s almost like a sauce πŸ˜‰

    This looks amazing. I’m going to have to google translate what lemongrass is in Portuguese so that I can see if it’s available here in my little corner of the world.
    Blessings Sylvia=)
    P.S. I was going to nominate you for the ‘versatile blogger’ award, but after researching your awards part of the site I noticed that you already have that.

    • superfoodista says

      Thank you so much Staci! πŸ˜‰ I think it’s “Capim Santo” if I am not mistaken. I went to a restaurant in SΓ£o Paulo a while back and they had a capim santo brigadeiro which was lemongrass. Hopefully you can find it πŸ˜‰ I could not find fresh one here in Miami unfortunately, but I will keep looking for it!
      Oh, so sweet of you for thinking of nominating me πŸ˜‰ Means a lot!
      Have a wonderful rest of the week and thanks for stopping by!

    • superfoodista says

      Thank you so much dear! πŸ˜‰ I know, Thai food is really my favorite cuisine…so fragrant and never gets old. Love lemongrass too – it’s so fragrant – have you ever tried a lemongrass juice? Fantastic!! I wish I could find some fresh lemongrass stems here….Thanks for stopping by today! πŸ˜‰

    Yum!! I absolutely can not wait to see your upcoming posts on more Thai food – I just booked flights for a SE Asia trip this spring, which includes 6 days in Thailand. I’ll definitely be taking notes!

    • superfoodista says

      Thank you so much dear! πŸ˜‰ Cool! When will you travel to Thailand? I will include some restaurant tips one of the upcoming posts for Bangkok. I went to some most amazing places there you have to try in case you will be in Bangkok! Lucky you get to travel there! πŸ˜‰

      • GirlEatsGreens says

        We’re going mid-May and doing just 2.5 days in Bangkok – spending 5 days in either Ko Samui or Krabi (and then the other 7 days in Vietnam and Cambodia). I’ll be on the lookout for your Bangkok recommendations! :)

        • superfoodista says

          Sounds fantastic! I wish I could go back to Thailand again πŸ˜‰ If you are still debating whether Koh Samui or Krabi, I think Krabi is more special, it’s less touristic than Koh Samui. And oh wow, Vietnam and Cambodia – fantastic! You must visit Angkor Wat if you have time, one of the most amazing things I have seen πŸ˜‰ Great, I will post the restaurant tips for Bangkok next week probably, hope you can visit one of them πŸ˜‰ hugs, Sylvia

    • superfoodista says

      Thank you so much Renee! Yes, didn’t you take a Thai cooking class? I think I read about it! Thai cuisine is amazing! What I love most about it, is its use of all these spices and wonderful fragrant herbs. And lemongrass is one of my favorite ones! So good!! I also love the lemongrass juice they make πŸ˜‰ Ah, already miss to be there and Asia in general!

  5. Deena Kakaya says

    Love this fragrant dish! My honeymoon was in Thailand do I have fond memories. I have a soup like this on my site with tomatoes, basil, lemongrass and rice noodles. Xx

    • superfoodista says

      Thank you so much Dimple! πŸ˜‰ Yes, the soup really tastes very refreshing and very fragrant. Yes, you must go to Thailand if you have the chance – the food is just too good there!! And it’s really cheap to travel around and eat out too πŸ˜‰
