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!

Jen’s Free Soup Challenge
I’d love for you to soup it up with me! For 5 days, I’ll send you a daily veggie-packed soup that’s easy enough for a busy weeknight and makes enough to freeze and pull out all winter.
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 Freezer System.
- 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), and these tips work for any of my vegan soup recipes.

Recipe Notes
- Noodle Swaps: If zucchini noodles aren’t your thing, use brown rice or millet ramen noodles instead.
- No Spiralizer: Use a vegetable peeler to make long zucchini ribbons.
- Spice Level: For a milder soup, leave out the serrano and use half the curry paste.
- Storing: Refrigerate leftovers in an airtight container for up to 3 days. The zucchini noodles soften as they sit, so for meal prep store them separately and stir them in when you reheat the soup.

This soup turned out so pretty and so fresh. I really like how light it was. – Yet filling. I saw someone else added a little basil on top and will try that next time.
Loved this soup! I accidentally bought an Asian Chili paste instead of curry paste when shopping, and didn’t realize until I had already started, so I just went with it, and it was delicious. Looking forward to trying it with curry paste next time as this will be on regular rotation. I added some home made bone broth as I am trying to incorporate that into my daily diet as much as possible. It cut the richness somewhat but left the flavor profile and win- it stretched the recipe so I had more wonderful soup. It is very satisfying and filling. I had it as a side to dinner, and ended up having a little more soup and saving the rest of my dinner fo another day!
That IS a total win Michelle! So glad to know that Asian Chili paste works well here too. Thanks for sharing!
My favorite of all the soups I’ve made. Definitely like green curry better than red.
The Best! Definitely my favourite so far!
I liked this but didn’t love it. I used 3 tbsps of green curry, which gave it just a little heat, but I could’ve used the entire ¼ cup. If I were to make this again, I would add another carrot. One carrot just sort of disappeared in the coconut milk. I really loved the spiralized zucchini, and the soup had good flavor.
