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

    This recipe makes what looks like it should be a tricky soup amazingly easy. I added a lot more curry paste, almost double, but that’s because I love these flavors strong.

  2. 5 stars
    So good!
    My husband always orders this when we go out for Thai and he was impressed with this version.

  3. Seemed a lot of coconut milk; so I used two cans and 2 cups of broth… [also so I could use up some of a big batch of broth I made to use through the soup challenge ]. Worked well!

    And another lovely use for zoo noodles!

    I like adding coconut milk to a lot of other soups and sauces… Like my carrot ginger soup! Also curry…Not so much that it’s overly spicy but just to add a lovely nuance to the flavor! [Umami!]
    Thanks for including this one!

    I love ordering this type of soup at Thai restaurants, so I was really hoping to LOVE this recipe. Unfortunately, I thought it lacked complexity and with the amount of fat, it really needs to be a ‘stunner’ for me. It is a BEAUTIFUL soup – so colorful and bright. It was not nearly spicy enough for me ‘as written’ so I will definitely be adding more curry paste as I eat my way through this batch.

  5. 5 stars
    This is an aesthetic soup to me, and you know what they say, you eat with your eyes.
    I traded one of the zucchini zoodles for a handful of thin rice noodles.
    I topped this beauty with fresh Chinese cabbage and green onion tops from my garden, and Serrano chilies, and cashews, drizzled with fresh squeezed limes.
    Wow! That Thai Red Curry Paste is a game changer with all these other flavors!!
    Like you said, this is something I want to take to dinners with family and friends as well!!
    Wow!

    This soup has such great flavor and was easy to make. I love the coconut flavor with the vegetables and will definitely make this again.

    This was very good and the first time I have made a soup of this type. Very glad and will do again. Mine was a lot darker than the pictures – I think the portabella mushrooms were the cause of that. Extremely tasty and the mushrooms give it a meaty flavor.

  10. 5 stars
    Absolutely delicious! Loved the combination of mushroom and vegetables in the sweet creamy soup with a hint of spicy. The toppings were just perfect. Wouldn’t change a things!

      Good soup. My husband is not fond of curry, so I went light on that. We do like Thai food. I am enjoying using my vitamix

    Good Thai Coconut Soup! My first time making this style of soup and I’m not one for spicy so it’s on the mild side. Yummy!

    Day 7 – The Thai Coconut Soup was a delicious change of pace. I loved the spice and the chance to bring out the spiralizer from the cupboard. It reminded me that I should use it more! This was my first time tasting Thai Coconut Soup. I’m so enjoying all these soup recipes. Soup never has to be boring and every recipe this week has been extraordinary. You are taking me to school!!!!
