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 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).

Recipe 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’m not a big coconut milk fan but this was good, easy and flavorful. I forgot to buy a serrano pepper and I think it was missing the spice to me so when I make it again, I’m going to make it spicy.

    Soup is excellent! Quick to prepare especially after prepping vegetables. I made three times the batch as I enjoyed this soup as I love coconut. In addition to zucchini, carrots, and mushrooms, I had a cauliflower. I used two cans of coconut cream and 10 cans of coconut milk. I wished I had added more carrots and additional Cremini and shiitake mushrooms. The addition of chopped cashews, scallions and peppers was wonderful. I added spinach to a warm up of the soup today and it is so good. This is the best soup ever!

    1. Your adjustments sound great, Janie! So glad you like this one!

    This is my favorite so far. Loved the creamy richness the coconut milk provided. Also. the flavors and the spice from the Serrano pepper. This one is a keeper.

    1. This one is definitely our most different recipe in the Soup Challenge. Glad it was a hit!

    Creamy & delicious! Due to the high fat content of coconut milk, I guess it’s good for being as a once-in-a-while treat!

    1. If you’re wanting less fat, try swapping for light canned coconut milk!
