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.

It was too rich for me, and needed more vegetables. If I make it again I will use part vegetable broth and and more carrots and mushrooms. Zucchini serial did not add anything for me so I will use rice next time.
Def let us know how you like it next time with your add-ins!
Came out great!! I made it with full-fat coconut milk and just added simple green onion as a topping and it was delicious. I maybe would make it next time without using the ribbons of squash… it made it kind of difficult to get everything on the spoon when I was eating it. Otherwise, loved this! Full flavors, and it stayed well in the fridge when I prepped it the night before.
This soup had an earthy taste from the mushrooms and the Thai curry paste added a lovely depth to the recipe. I will definitely add this to my menus!
A truly satisfying meal! It was delicious with a shot of Tamari in it, as I forgot the salt when I was making it. This was the second time I have made it and I really enjoyed it both times. It was a quick and easy make and would have been even quicker if I had had some red curry paste to hand, I had to make some from scratch!
Good soup. Very rich. I used 3 cans full fat coconut milk and 1.5 C vegetable broth. On my second bowl (it’s all I’m having for lunch) and I can feel the effects of the richness.
One thing I’d do differently is saute the carrots first so they end up softer. I was concerned the milk would burn simmering too long so they were a little crunch. Very good soup and is certainly a keeper.
Sautéing the carrots first is a great work around Tracy!
