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

    Thai Coconut Soup was not my favorite and was too spicy for our taste. It was easy to make and I used Blue Elephant Thai Premium Paste Red Curry. Next time I WOULD NOT USE IT. I will add my own spices. I added more mushrooms and carrots, and tomorrow I will add rice to cool it down. I love using only vegetables and it will probably help our cholesterol.

    IThis delicious soup reminded me of lobster Bisque which is fabulous! Next time I may even add some lobster/shrimp and a wee bit of sherry! Great job Jen!!

    I made it exactly as the recipe described. I use the Serrano pepper, onion, lime and cashews as toppers. My husband and I ate a bowl full. My husband did not like it at all, I probably won’t make it again.

    1. Gotta keep those loved ones happy! Thanks for giving it a try Linda. 🙂

    Husband thinks it needs more heat….next time I’ll leave the Serrano seeds and membranes in !!! I think it would be good to add bok choy. This was an easy one!

    I loved the flavor but my kid who likes soup said it was too bland. Not sure what else I could have done as I did add the cashew cream and pesto. It is a winner for me!

    This soup was delicious! I have not tried a coconut milk soup base before and was surprised at how flavorful a few veggies and curry paste made the soup! I would like to try adding more veggies next time. Thanks for this recipe!

    I added the noodles and slice the zucchini instead. It makes the soup a meal, and that saved me some work for making dinner for my 5-people family. Love the soup, especially when lemon was added.

  8. 3 stars
    Not my favorite. Really liked the mushrooms & carrots, but I’m not a big gan of a “creamy soup”

  9. 5 stars
    This was so good and surprisingly easy to make with minimal ingredients. I used Thai kitchen lite coconut milk and Thai Kitchen red curry paste and it came out so creamy and flavorful. I will definitely be making it again.

    This is a tasty recipe, easily customized by adding what you like (egg, tofu, etc.)… or leaving it as is to be a light supper on its own or as a side.

    Thoroughly enjoyed your vegan tomato soup and this was even better! It was so easy to make. I always thought it’s too complicated to get the spices right for Thai soup or curries. But I used mekhala organic red curry paste and it tasted so authentic. My husband loved it too! We added extra carrots, mushrooms and some green peas to pack in more veggies. I’m definitely going to make it again.

    Loved the flavor – coconut is one of my favorites. A little too brothy for my taste but will add more veggies next time.

    This was so good! The biggest surprise for me was how much I enjoyed the zucchini in it! I think I will add more carrots and mushrooms next time, I just love them!

    I was not able to get the curry paste and tried to compensate on my own. I’ve never had a curry soup and would like to make it again with the paste. I added lemon grass, onion, garlic and a pepper.

    This soup is amazing! I topped it with thai basil, cilantro and green onion with a squeeze of fresh lime. I added chicken. My husband loved it as well! We will definitely make it again.

    Coconut soup was good but the amount of curry specified in the recipe in my opinion was too much curry.. The soup came out extremely spicy
    I will definitely make it again but only 1/2 the curry
    It specified on recipe.

    Soup 3 of the ten day challenge,
    It has taken me about 4 try’s to get it to a taste the way my whole family likes It. today I added lemon grass and reduce the coconut milk to half and use broth to make the difference. Also I made my own version of the Thai paste.
    Overall it was nice

  18. 5 stars
    Nice warm blend of flavors! Creamy and rich. I didn’t have quite enough coconut milk, so I added a bit of cashew cream. Also added a cup of cooked rice to include a grain; quinoa would also work. Is interesting enough to serve to company, perhaps with a crisp side salad and naan. Love all the toppings! I think peanuts and cilantro would be great toppings too. Excellent!
