What occurred to me while simmering this Tom Kha Gai soup is how amazing it smells! Those kaffir lime leaves are like pot pourri for your house – such a fresh lime aroma!
If you like Tom Yum soup, then you’ve got to try this coconut chicken version. It’s such an easy recipe, and it only takes 20 minutes to make. You can’t help but feel replenished from the hot and sour broth. So rich, yet so light! You don’t have to make your own chicken stock, but if you do, it’s all the more delicious.
What is Tom Kha Gai Soup?
Tom kha gai or tom kha kai is a Thai coconut soup that accentuates galangal. It’s a spicy and sour soup with a rich component from canned coconut milk. Traditionally, this hot soup is made with kaffir lime leaves, lemongrass, cilantro, mushrooms, chicken, fish sauce, and lime juice.
What makes this a Traditional Thai Soup?
This Tom Kha Gai incorporates all of the traditional ingredients. Galangal is available in Asian grocery stores. The pale root is sold in packages frozen here in the US. If you can’t get the galangal, you may substitute ginger, which is far easier to find; unfortunately, ginger is very different in flavor so it won’t be 100% Tom Kha Gai since it is named after the root.
Curry Paste Variation
Another substitution would be to use Thai kitchen red curry paste (which contains lemongrass and galangal). To do this, stir in 4 Tablespoons.
Working with Lemongrass
Since many of you may not have lemongrass growing in your backyard, you can likely find it in the produce section. It’s easy to work with, and you can cut into it using a sharp chef’s knife after removing the tough outer layer.
