Craving something warm, creamy, and full of flavor but don’t have hours to spend in the kitchen? This 30-minute vegan Thai coconut soup is my gift to you. It’s a quick and cozy take on the classic Tom Kha, made with tender mushrooms, sweet carrots, and creamy cashews for a satisfying, plant-based soup.
The rich coconut broth is infused with bright notes of lime, lemongrass, and a hint of heat—comfort food with a Thai-inspired twist. I’ve made this soup more times than I can count and I never get tired of it. I love it so much that I included it in my cookbook, Simple Green Meals.
Thailand Origins
Thai Coconut Soup, often called Tom Kha Gai, traditionally includes chicken and hails from northern Thailand, usually served with rice. My plant-based version swaps the meat for cashews and keeps it grain-free with zucchini noodles. Classic ingredients like ginger, lemongrass, and kaffir lime leaves add bold, aromatic flavor—feel free to include them!
Why This Thai Coconut Soup Rawks
- It’s a one-pot wonder. Simmer fresh veggies right in creamy coconut milk, soaking up every drop of Thai-inspired flavor. It’s got a cozy, spicy kick—just enough to warm you up without setting your mouth on fire. Not into heat? No problem. Simply dial back the curry paste and skip the serrano peppers to keep things milder.
- This soup actually gets better with time. Make it a day ahead and let those bold flavors mingle overnight. Just hold off on adding the zucchini noodles until you reheat—it keeps them from getting mushy and makes the whole bowl taste fresh and vibrant.
- It’s packed with plant-based nutrients. Between the mushrooms, carrots, zucchini, and creamy coconut milk, you’re getting fiber, antioxidants, and healthy fats in every spoonful—aka fuel that tastes amazing.
- It’s ridiculously fast. This soup comes together in about 20 minutes, making it perfect for busy weeknights when you want something warm, nourishing, and not boring.
Storage Tips (Without the Mess)
One of my favorite things about soup? You can make a big batch and enjoy it all week—or freeze it for future “I-don’t-want-to-cook” nights. Thai coconut soup stores beautifully, but here’s a few pro tips:
- Skip adding the zucchini noodles if you plan to freeze it. Zoodles tend to turn mushy and slimy after thawing, and they’re super quick to toss in fresh when you reheat.
- Store your soup in a freezer-safe container or bag. I love Souper Cubes (use code Jen10 to get 10% off!)
- If you’re using glass jars, leave some space at the top for the soup to expand as it freezes (learned this the hard way with a shattered mason jar—zero stars, do not recommend).

Notes
- If zucchini ‘noodles’ aren’t your thing, then swap for brown rice or millet ramen
- You can use a vegetable peeler to create zucchini strips if you don’t have a spiralizer.
- Use full fat canned coconut milk for the richest flavor, use light canned coconut milk for less fat
- The nutrition facts are based on full-fat canned coconut milk. Use light canned coconut milk for fewer calories and fat.
- Omit the chili pepper and halve the amount of Thai curry paste for a less spicy meal

I really wanted to like this soup more than I did. I don’t like milk, so that could be my issue. I love the consistency of the zucchini noodles, the crunch if the cashews and the lime juice brought it to a new level. It was just too milky for me. Maybe if I had it as an appetizer, smaller serving, I would have enjoyed it more.
You could def use less milk and broth, plus more veggies to make it a consistency you’d enjoy more. We’re all about making it your own!
The taste was smooth and creamy. The aroma took my breath away and I felt swept away to a tropical island.
This one is a keeper with a few adjustments. We love spicy so I threw in the pepper to meld while cooking along with a couple of tablespoons of red crushed pepper. I do not have a spiralizer, so I thinly sliced the squash. Also added a bit of rice. Next time, I will double the veggies as it seemed a bit of a waste of coconut milk.
This soup was interesting. Not spicy at all. But adding the little extras were a must. I had an extra mushroom so fried it up and added it along with the cashews and onion but oh my adding extra lime was a must for me. Completely changed the soup in my mind.
Super easy to make but flavor a little lacking. I don’t handle spices so it was difficult to use spice for flavor without making it too hot to eat or trouble my stomach. My husband didn’t care for it but he also doesn’t like mushrooms. Will see if the flavors are enhanced tomorrow.
So yummy!!! So healthy!!! But best of all, SO SIMPLE!!!
My favorite soup recipe so far. I can’t wait to share this with my mom, sister and my daughters!
Thanks for sharing Kristina!
My favorite so far in the 10 day soup challenge
This is a lovely, mild soup. I used 1/2 light coconut milk and 1/2 full fat coconut milk and thought the texture was very good. It’s got a mild flavor, so next time I will heat it up a bit more with more curry paste or some siracha. My husband likes this one too!
It was such fun to make a soup different from the usual. And ingredients were still simple and steps quick and easy! I only added a bit more pepper for an extra kick. Delicious!
Really loved this Thai coconut soup. I did omit the curry paste. It was to spicy for us. Everything else was delicious. Will definitely make this recipe again.
I didn’t get a chance to make this one yet but I can tell from the ingredients I’m gonna love it! Tonight took us to the last fair of the season in Maine so this will be on the menu tomorrow night!
This soup is all about the toppings. The coconut thai base is simple and delicious, but you can load it with whatever toppings you can dream up. A favorite for sure.
Loved this recipe! I was so excited to try it once it was ready that I forgot to photograph it! So far, this is my favorite and it was so easy!
You know it’s good when you forget to grab that pic for IG! Kale yeah!
Me and my family enjoyed the soup very much. I made with less with coconut milk to keep it liter with calories.
Better than I expected… I used the lower fat coconut milk as I thought the full fat would be too rich for me… and it was really good.
This one was okay. Needs a little bit more something, not sure what. I used Thai red curry paste, not sure the difference between red and green I’ve only used red curry paste once before this. I did use Trader Joe’s organic coconut milk and have to say it’s the best canned coconut I’ve ever used. So many of them separate where the fat is so hard it’s difficult to incorporate. Because of that I researched coconut milks and found Trader Joe’s was rated high because of the consistency. Just wish there was one closer to my home. I’ll try this one again but maybe adding more mushrooms, Thai curry paste, and maybe some cilantro.
My favorite soup so far! I didn’t change a thing!
Confession – I have never cooked with coconut milk. It’s embarrassing I know. Imagine my surprise when I tasted this devine (yes a holy experience) soup tonight, mind blowing! This was amazing and I don’t even feel bad having used full-fat coconut milk. I added a little brown rice that I had left-over from last night’s dinner and this was a perfect meal. Can’t wait for lunch leftovers tomorrow! Thank you!
Great flavors. A little to spicy for me. I would add the peppers if you like it spicy. Adding the basil, lime juice and cashews help tame the heat. This soup definitely fills you up.
Feel free to back off on the curry paste a bit if that helps as well, Sombra. So glad you tried it!
