My best-ever tom kha soup recipe is already perfect, but it’s even better when it’s made in the Instant Pot! Rich, creamy, and full of incredible flavors, this Thai coconut chicken soup recipe is easy and delicious. Easily make it Whole30, paleo, or vegan, too.
What Makes This Soup So Good
- If you’ve tried my Best Ever Tom Kha Gai Soup, then you totally understand why it’s one of my most popular recipes. It’s light and filling, creamy and rich, tangy and sweet.
- Making tom kha soup in the Instant Pot is the fastest way to get this delicious dish on the table. Our slow cooker version is super easy, but you’ll need 5 hours minimum to make it. The Instant Pot shaves an extra 15 minutes off the classic stove-top version, so you’ll have a giant batch of Thai coconut chicken soup in basically 30 minutes.
- This recipe can fit a variety of dietary needs! You can adapt this recipe to be Whole30-compliant, paleo, vegan, or vegetarian. Want a seafood version? Use shrimp instead of chicken!
Key Ingredients
Red Thai Curry Paste – The secret ingredient to the best tom kha soup, whatever method you use to make it. It’s a little sweet, a little spicy, and a little savory, and it gives the soup SO much flavor.
Lime Leaves – Kaffir lime leaves are optional, but I highly, highly recommend using them! They add SO MUCH flavor to tom kha gai, and it’s a little different than the flavor you get just from using lime juice.
Coconut Milk or Cream – The creaminess of tom kha soup comes in here. Be sure to use coconut milk or coconut cream. Coco lopez/coconut creamer are not the same and won’t work here!
Chef’s Tips
- Leftover Instant Pot tom kha gai will keep up to a week. Just refrigerate it in an airtight container!
- Lemongrass is popping up more and more in grocery store produce sections. If you can’t find it fresh at your store then minced, refrigerated lemongrass will also work.
- Instant Pot tom kha soup can be tweaked to your palate, so make any adjustments you need or want to! Add more sugar for sweetness, more lime juice for tartness, or more fish sauce for saltiness. Serve it with fresh limes, add more mushrooms, or skip the cilantro.

Instant Pot Tom Kha Soup (Thai Coconut Chicken Soup)
My best-ever tom kha soup recipe is already perfect, but it's even better when it's made in the Instant Pot! Rich, creamy, and full of incredible flavors, this Thai coconut chicken soup recipe is easy and delicious. Easily make it Whole30, paleo, or vegan, too.
Equipment
- Instant Pot
- Silicone spatula or wooden spoon
- Slotted spoon
Ingredients
- 1 tablespoon coconut oil
- ½ of one onion sliced
- 2 cloves garlic chopped
- ½ of one red jalapeño pepper sliced, or a couple Thai chiles, halved
- 3 ¼-inch slices galangal or ginger
- 1 stalk lemongrass pounded with the side of a knife and cut into 2-inch long pieces
- 10 kaffir lime leaves torn, optional
- 1 tablespoon red Thai curry paste
- 4 cups chicken broth see Notes for vegan or Whole30
- 2 13.5-ounce cans full-fat coconut milk or coconut cream
- 2 chicken breasts about 1 pound, cut into bite-sized pieces; see Notes for vegan or to use shrimp
- 8 ounces white mushroom caps sliced
- 2-3 tablespoons brown or coconut sugar see Notes for Whole30
- 2-3 tablespoons fish sauce plus more to taste
- 2-3 tablespoons lime juice fresh
- 2-3 green onions sliced thin
- cilantro fresh, chopped, for garnish
Instructions
- Set Instant Pot to Sauté mode. Add coconut oil and heat over medium heat. When oil is hot, add onion, garlic, jalapeño, galangal (or ginger), lemongrass, lime leaves, and red curry paste. Stir frequently, cooking for 5 minutes or until onions are softened.
- Pour in chicken broth and stir. Secure lid on Instant Pot with vent in sealing position. Set to cook 5 minutes on Manual High Pressure.
- When 5 minute cook time is up, carefully Quick Release pressure and remove lid. Set Instant Pot back to Sauté mode. Use slotted spoon to strain out garlic, onions, lemongrass, lime leaves, and galangal. Discard aromatics.
- Add in coconut milk, chicken breasts, mushrooms, fish sauce, coconut sugar, and lime juice. Simmer in Sauté mode until chicken is just cooked through.
- Taste soup and adjust as desired. Add more sugar for sweetness, more lime juice for tartness, or more fish sauce for saltiness. Ladle soup into serving bowls and top with sliced green onions and fresh cilantro. Serve warm.
- 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 instead of chicken: Add 1 pound of raw shrimp instead of the chicken and heat until it’s cooked through (it’ll be pink and no longer translucent).
- Make it Vegan/Vegetarian: Use 2 additional cans full-fat coconut cream or coconut milk instead of chicken broth. Sub chicken with tofu. Use a 1-pound block of firm or extra firm (can be regular or silken) tofu cut into cubes. Use soy sauce to taste instead of using fish sauce.
- Make it Whole30: Use 2 additional cans full-fat coconut cream or coconut milk instead of chicken broth. Use 2 tablespoons of coconut aminos instead of coconut sugar and use fish sauce without sugar (the only one I know of is Red Boat Fish Sauce).

I just made this and it’s fabulous! Thank you so much! This is going on my weekly rotation!
We’re so glad it’s earned a spot in your weekly rotation! Thanks for sharing, Dawnmarie!
Very Tasty. The only issue I have it that it is SO watery. Like it should be for over rice or something. Not quite the texture of soup. Any thoughts on making it more of a soup?
I’m so sorry this wasn’t what you were hoping for, Linda! It’s definitely meant to be a thinner, broth-y soup with a touch of creaminess. Were you expecting something thicker and creamier like a potato soup?
Did you use canned coconut milk/cream, or did you use a carton version? A carton coconut milk/cream is much thinner than the canned variety so you’d definitely lose some creaminess there.
I suppose you could try using less chicken broth, but you risk a burn warning on the Instant Pot if you don’t have enough liquid in it.
Loved it, made it with prawns, can I freeze?
We’re so glad you loved it! Yes, you can definitely freeze it! 😊
So delicious and fast!
So happy you loved it! 😊
I’m about halfway through making this! The onions and garlic look beautiful. Wondering if there are any suggestions for using these instead of discarding them?
Ooh, we haven’t used the excess onions and garlic in anything- be sure to let us know if you try adding them to something!
Wonderful taste and pretty easy!
One change: I added the chicken breast and mushrooms to the pressure cooking step, increased the time to 8 minutes, then let it slow release. This takes the guesswork out for cooking the chicken and got the mushrooms more tender. I did have to be careful to save the mushrooms during the straining portion.
Another change was just a matter of preference, I used half the suggested fish sauce and compensated with salt.
Lastly, this recipe calls for only 2 cans of coconut compared to the stovetop version that uses 4 cans? I used about 3 cans when making it.
Hi Sean! Thanks for the helpful tips! We used 2 cans of coconut cream in this recipe to accommodate the smaller size of the Instant Pot. You can definitely adjust it to your taste preferences! 😊
It’s the best recipe. I like the page layout with pictures! I get a good visual for what to do step but step. I like the 3 options for cooking, instant pot, slow cooker, stove top. (I’ve made them all.) I’ve made this recipe about 6 times in the past 3 months. Gives me confidence in other 40 Apron recipes.
Thanks so much for taking the time to share your feedback with us, Carolyn! So happy you enjoyed the soup!
I don’t have a insta pot can you give me the instructions for stove top please
Hi, Elaine! No problem at all – our original tom kha recipe is cooked on the stovetop! It’s linked above in the “What Makes Instant Pot Tom Kha Soup So Good” section, but you can also find it here. Hope you love it!
You can also use a stovetop pressure cooker.
FYI It’s called an Instant Pot. Many make that mistake. Even I did before I got mine. I love it!
