A few months ago we ate at a local Thai restaurant and they served Tom Kha Gai soup to start the meal. We’ve eaten in a hundred Thai restaurants over the years and somehow had never tried this soup. It’s a flavor explosion of lime, lemongrass, galangal, ginger, and coconut. Once I discovered it, we’ve been Thai restaurant hopping around town to try different versions. And though the broth is similar, every restaurant has a unique twist on the other elements. I’ve made a dozen versions to come to this Tom Kha recipe – it’s a perfect balance of salty, tangy, creamy, sweet and spicy.

It turns out that it’s very simple and amenable to variation. I’ve added a few more vegetables than restaurants serve, but it makes for a heartier soup.

I improvised on a couple of traditional Tom Kha that can be difficult to find: Chinese broccoli and kaffir lime leaves. I swapped in standard broccoli for Chinese and the juice and zest of two limes instead of the lime leaves. If you can find either of the traditional ingredients, use them! 10 to 12 lime leaves for the lime juice and zest and an equal amount of Chinese broccoli. And if you can’t find galangal, use an equal amount of standard ginger.

    I love adding coconut in dishes, but this post made me think that I’ve never added it in soup. I’ve got to fix this! And this chicken coconut soup is the perfect place to start 😉

      I’m so excited for you to try it, Ben!

    I’m obsessed with Thai – so this is going on my MUST make list. Can’t wait!!

  3. David @ Spiced says:

    So I had no idea what it was called, but I think I’ve had something similar to this soup before. Laura and I went to a Thai place near us, and it was delicious…but I totally forgot about that soup until I saw this recipe. Looks delicious, Marissa, and I’m thinking a batch of this one would be welcomed on a cold day soon! 🙂

    I heard raves about this soup a few times, but of course I never took the time to make it. I really need to expand my asian food section, they have great flavors and are healthy usually. Looks divine Marissa!

    This is one of my favourite soups! I find it a bit more filling than Tom Yum so we love it for dinner. Your version looks fantastic! 😀
