This tom kha gai soup recipe (or Thai coconut chicken soup) is absolutely perfect. Rich and creamy yet tangy and salty, this Thai coconut chicken soup recipe is filling but light and positively bursting with flavor. The very best tom kha gai recipe I’ve ever made or tried. With Whole30, paleo, and vegan options, too.
My Favorite Thai-Inspired Soup
Let’s go ahead and talk about the best soup of all time.
That’s right: tom kha soup. AKA Thai coconut chicken soup. AKA tom kha gai.
So here’s the deal: this tom kha gai (Thai coconut chicken soup) is perfection. It’s creamy and a bit tart and salty and a bit sweet, and the chicken is tender, and the mushrooms are filling, and the fresh cilantro adds the perfect herbaceous edge, and I can’t get enough of this soup. I don’t think you’d ever need another Whole30 Thai coconut chicken soup recipe, or heck, a plain ol’ non Whole30 Thai coconut chicken soup recipe for that matter, because this recipe is so damn good.
And you know what? I have a really solid story to go along with this recipe.
Skip the Takeout and Make This at Home!
When I was in college, I fell in love with cooking. Like, swept me off my feet, fall flat on my back, obsess over it day in and day out in love. And so, it being 2006, I started a recipezaar.com account. I went into detail about my obsessions and how the one recipe I always wanted to learn to make was the fresh salsa from my favorite Mexican restaurant. In fact, you can read the story and get the recipe for the best restaurant style salsa ever by clicking here. You’ll thank me later (pretty sure).
The Story
What happened was this: a guy at my college found my profile on the recipezaar.com and saw that it was my lifelong dream to recreate this salsa. He reached out to the head of marketing or CEO or something like that at the restaurant in question and told her this sob story about how we were engaged and living abroad and I was terribly homesick and all he wanted to do for Christmas was make me a giant feast to remember home, including this salsa that I loved so much, of course.
So Then What?
So what did she do? She gave him the recipe of course. Of course.
And then he gave me the recipe of course. Of. Course. And then we got to talking and…
No, our leading fella isn’t my husband and the father of my children (because wouldn’t that be just too damn much?), but he did do the same thing for me later with this tom kha soup.
You see, there’s something about this recipe that’s just not like the others. Something better.
This tom kha soup is based off the exceptional dish found at a local chain of restaurants in the state where I went to college. It was different than the Thai coconut chicken soup I’d had before, and it sold me forever and ever on Thai food. I couldn’t quite put my finger on it solo, though, but it all made sense when he got me the secret recipe.
Why This is One of the Best Soup Recipes Ever
- There’s a secret ingredient that adds a savoriness to this Thai tom kha gai coconut chicken soup recipe that takes it all to the next level.
- It’s creamy and sweet and salty and spicy and bright all in one.
- This tom kha soup recipe is actually quite easy to make and doesn’t require hard-to-find ingredients. You should be able to get everything from a traditional Western grocery store.
- I’ve included Whole30 and vegan options so you can enjoy this tom kha soup all the time, even if you’re avoiding added sugars or you don’t eat animal products.
A Note from Cheryl: Years ago, we referred to certain ingredients in this recipe as “weird”, a term we erroneously used to describe harder-to-find ingredients that are generally unfamiliar to the average American reader. In using this term, though, we unintentionally contributed to furthering the stigma that these ingredients are somehow “not normal”. That was never our intent, but it was our impact, and that’s what matters.
What’s the Secret Ingredient?
It turns out it’s quite simple, really: red curry paste. Just a bit of red curry paste added to an otherwise pretty traditional recipe for tom kha soup, making it way easier for me to make on a regular basis.
Speaking of easier… you can also swap ginger for galangal and swap fresh lime juice for makrut lime leaves. As much as I love the international market, I just don’t get there enough to satisfy my Whole30 Thai coconut chicken soup craving if I have to use those hard-to-find ingredients!
Where Can I Find Lemongrass?
I find fresh lemongrass in the produce section of almost every grocery store these days. If you can’t find it fresh, though, you can usually find a refrigerated tube of it, minced, in the produce area. Ask your clerk and tell them it’s important! You can’t make the best ever tom kha soup without it!
Can I Make This Soup Vegan?
To make this tom kha soup vegan:
- Use vegetable broth instead of chicken broth.
- Substitute soy sauce for the fish sauce.
- Add a 1-pound block of tofu, cubed into bite-sized pieces, instead of chicken.
And you won’t call it “tom kha gai,” if you don’t use chicken. You can call it “tom kha tofu”!

Best Ever Tom Kha Gai – Thai Coconut Soup
Ingredients
- 1 tablespoon coconut oil
- half of one onion thinly sliced
- 2 cloves garlic chopped
- half of one red jalapeno pepper sliced; or 1-3 Thai chiles, halved
- 3 ¼-inch slices galangal or ginger
- 1 lemongrass stalk pounded with the side of a knife and cut into 2-inch long pieces
- 2 teaspoons red Thai curry paste
- 4 cups chicken broth see Notes if vegan or on Whole30
- 4 cups canned full-fat coconut cream unsweetened, or full-fat unsweetened coconut milk; see Notes
- 2 medium chicken breasts cut into bite-sized pieces, approximately 1 pound
- 8 ounces white mushroom caps sliced
- 1-2 tablespoons coconut sugar see Notes for Whole30 option
- 1 ½ – 2 tablespoons fish sauce plus more to taste, see Notes if on Whole30 or vegan
- 2-3 tablespoons fresh lime juice
- 2-3 green onions sliced thin
- fresh cilantro chopped, for garnish
Instructions
- In a medium pot, heat the coconut oil over medium heat. Add the onion, garlic, jalapeno or chile, galangal or ginger, lemongrass, and red curry paste and cook, stirring frequently, for 5 minutes, or until onions are softened. Add chicken broth and bring to a boil. Reduce heat and simmer uncovered for 30 minutes.
- Strain out the aromatics (the garlic, onions, lemongrass, and ginger) and discard. Add in coconut cream or milk, chicken breast (or tofu or shrimp), and mushrooms. Simmer until chicken breast pieces are just cooked through, then add fish sauce, coconut aminos (or coconut sugar), and lime juice, plus more of each to taste.
- Cook 2 minutes, then ladle into serving bowls and top with sliced green onions and fresh cilantro.

- Be sure to use coconut cream or coconut milk. Coco lopez and coconut creamer are not the same as coconut cream/coconut milk and will not work in this recipe.
- To use shrimp, simply stir in 1 pound of raw shrimp instead of chicken. Simmer until just cooked through, pink, and no longer translucent.
- Make it Whole30: Use compliant chicken broth. Use 2 tablespoons coconut aminos instead of coconut sugar. Use Red Boat fish sauce – this is the only fish sauce I’ve found to be compliant.
- Make it Vegan/Vegetarian: Use vegetable stock, preferably an Asian variety. Use a 1-pound block of firm or extra firm tofu (regular or silken) cut into bite-sized cubes. For vegan, use soy sauce (to taste) instead of fish sauce.

What can I use in place of fish sauce since my closest grocery store didn’t have any? And do the aromatics (ginger and garlic) need to be strained out? I grated a bunch of ginger last night
You can use soy sauce, lite tamari, or coconut aminos instead of fish sauce. As for the aromatics, you don’t necessarily have to strain them out. It’s personal preference, but we recommend it. It also keeps you from biting into pieces of garlic or lemongrass or the quarter-inch slices of galangal or ginger. Since you grated your ginger, though, that’s not really a concern!
Loved this. I added fresh curry leaves to the recipe.
Yum! Thanks for sharing, Jan! 😊
4 is cups coconut milk .is that 1000 ml . That would make 2 litre fluid . Also csn I use brown sugar as I can’t get coconut aminos where I live in uk
Hi, Jean! 4 cups would be approximately 946 ml. Soy sauce would be a great substitute for coconut aminos! Hope this helps! 🙂
Outstanding. Next level.
Glad you loved it! 🙂
WOW, what a success! This recipe was really pretty easy and absolutely delicious! My husband would eat this every day if I’d make it. This evening I served it with jasmine rice and Thai iced tea. We live probably 150 miles from a good Thai restaurant, so thanks for this wonderful recipe that we can have anytime we want, to satisfy that special Thai craving for all the flavors showing off at the same time! SO GOOD.
Ooh, Thai iced tea sounds delicious! So glad you and your husband love it. Thanks for sharing! 🙂
I just made this exactly according to recipe, and it was extremely bland. Trying to save it with salt right now. Any help?
Hi! So sorry to hear you don’t love the flavor! Some people have increased the amount of red curry paste and lime juice. We would love for you to try this again!
Made this last night with chicken and it is delicious but we did have to amp the flavors for our taste. Next time I will double the aromatics so I don’t have to adjust so much at the end. Only substitution I made was light brown sugar in place of coconut sugar. As good as the one at our favorite Thai restaurant.
So glad you enjoyed it! Thanks for sharing. 😊
Well, I served it a second time and, if possible, it was even better than the first and drew rave reviews. The birthday celebrant that was my guest said that at his “last meal” he would definitely want to have this soup as one of the courses!!! So, it is wonderful indeed, and I will be making it again and again!
Wow! That is quite the compliment! So glad you and your guests loved the soup! 🙂
I’m about to make it for the second time – when I served it before, everyone raved about it – said it tasted better than what they’d had in the best Thai restaurants. I have a suggestion: when you say to add the onions, I’d say “all” the onions since in the list you have a 1/2 onion at the beginning of the ingredient list, and then the spring onions at the end, so I forgot to add them the first time. I’m hoping my second batch is as good as the first. LOVE this soup.
Thanks so much for your kind comment, Katharine! I’m so happy you loved this soup so much! With the onions, the sliced green onions at the end of the ingredients list are actually a garnish. They’re not added with the half an onion in step 1, they’re added at the end of step 3, right before serving. So you did it correctly the first time!
My husband is on low glycemic index diet and he has fat liver and high blood pressure. He can’t eat much salt and sugar. On the other hand i am vegan. Can i make this recipe without soy sauce/ fish sauce/ sugar and coconut aminos? Will it still taste okay? 😞
Hi, Marta! Those ingredients are pretty important to the overall flavor of the dish, unfortunately. It would most likely still be a good soup if you leave them out, but it wouldn’t have the exact flavor we’re going for here.
For the coconut sugar, you can try Brown Swerve instead (it’s a non-glycemic sugar alternative). For the fish sauce, since soy sauce and coconut aminos aren’t options, what about lite tamari? It’s vegan, and while it’s not no-sodium, it is reduced sodium compared to regular tamari and soy sauce. Reduced may not be enough for your husband’s needs, though.
