I would say that there exist a thousand unbreakable links between each of us and everything else, and that our dignity and our chances are one. The farthest star and the mud at our feet are a family; and there is no decency or sense in honoring one thing, or a few things, and then closing the list. ~Mary Oliver
This authentic recipe for Tom Kha Gai (Thai Coconut Chicken Soup) is full of amazing flavor and can be made quickly and easily on the stove top or in an Instant Pot pressure cooker.
What makes this Tom Kha Gai recipe truly authentic is the use of galangal root. So yes, it does require a trip to the Asian Market, but trust me when I tell you, you’ll love yourself for it. So will your family. And what is nice is, you can buy extra galangal root and kefir lime leaves and freeze them for future use, because I promise you’ll want to make this soup again. Soon!
The rich and fragrant coconut broth is especially comforting when feeling under the weather.
Galangal root (also called galanga) looks very much like ginger but tastes very very different. It has an exotic pine flavor, that in my opinion, totally makes the soup. In fact, the word “Kha” translates to galangal. Gai translates to “chicken, and Tom means “cooked”. Chicken cooked with galangal. So don’t make the soup, until you have time to go to the Asian Market. Trust me. 😉
While you are there, pick up some kefir lime leaves, ginger and lemongrass. Both the galangal and the kefir lime leaves may be in the frozen section of the market. You may also find chopped frozen lemongrass, which I happen to love, because then there is always some on hand in the freezer.
While I haven’t made a vegan version of this yet, I know it is possible using tofu (or fried tofu) and this vegan fish sauce.
You’ll ned about a quarter cup of both galangal and ginger and just a heads up- you don’t need to peel the ginger or the galangal, just thinly slice.
Thai red chilies are a nice addition to the soup too, but you can also use chili paste.
Make the Tom Kha Gai in an Instant Pot with chicken breast or chicken thighs, or cook it more authentically on the stove top. Your choice!
The instant pot version is very quick and easy- just put it all in the pot and set.
When it’s done squeeze with lime and serve in bowls.

Instant Pot Instructions:
- Place everything in the instant pot- except lime juice, using 1 cup chicken broth and leaving the chicken breasts or thighs whole. Don’t forget the salt. 🙂
- If using chicken breasts, pressure cook on high pressure for 7 minutes, or 10 minutes for thighs. If using tofu, pressure cook 4 minutes.
- Naturally release for 10-15 minutes. Shred the chicken into bite sized pieces using two forks and add the sugar and lime juice. Taste- adjust salt, lime and spicy heat. Serve with a lime wedge.
Stove Top Cooking instructions:
- Slice the chicken into thin bitesized pieces ( across the grain) and season with salt and pepper and set aside.
- In large heavy bottom pot or dutch oven, saute shallot in a little oil over medium heat. Add ginger, lemongrass, lime leaves and galalagal and 2 cups broth and simmer gently for 5 minutes, letting the broth infuse. Add the chicken (or tofu) and mushrooms and gently poach, simmering for 3-4 minutes or until chicken is just cooked through. Stir in the coconut milk, fish sauce, chilies, and salt and bring to a gentle simmer. Add the lime juice and sugar. Taste. Adjust salt and lime and the spice level by adding more chili paste.
It may smell “fishy” at first, but after you add the lime juice, it will all balance and mellow out.
When making the stove top version, sometimes I’ll poach whole chicken breasts in the infused broth (covered) then shred with 2 forks- a little longer cooking time, but no pre-cutting required. Then add the remaining ingredients. 🙂
Boiling coconut milk too long will take some it’s lovely sweetness away, so don’t over boil it or over cook it, just simmer gently and not for too long. 🙂
To make a vegan version, sub veggie broth for the chicken broth. Add crispy tofu. ( Pan- sear cubes of tofu in a skillet, with olive oil, salt and pepper) Add other veggies if you like! Sub vegan fish sauce for regular fish sauce.
Feel free to serve over rice or rice noodles.
