Easy Vegan Thai Coconut Soup: A Flavorful Tom Kha Gai with Sweet Potato & Kale
Embark on a culinary journey with this delightful, aromatic, and entirely vegan Thai coconut soup. Crafted with the wholesome goodness of sweet potato and kale, this recipe offers a simplified, weeknight-friendly, and plant-based take on the beloved classic, Tom Kha Gai. It’s a harmonious blend of sweet, sour, spicy, and creamy flavors that will transport your taste buds straight to Thailand.
My culinary journey took an exciting turn during the initial weeks of culinary school, specifically when I had my first encounter with a truly exceptional Tom Kha Gai soup. While our institution primarily focused on classic French techniques, we were fortunate to have Chef Somchet, a brilliant instructor from Thailand. She championed a school tradition: dedicating an entire day to mastering traditional Thai dishes, a day that quickly became one of my favorites.
At the culmination of that memorable lesson, Chef Somchet generously served us steaming bowls of the renowned Thai coconut soup. The aroma alone was utterly captivating, a complex symphony of fresh herbs, rich coconut, and subtle spices. Each spoonful was an exquisite experience, leaving me wishing for endless refills. It was then that Tom Kha Gai firmly cemented its place as one of my all-time favorite Thai creations, a dish I often reminisced about.
So, you can imagine my sheer delight when I stumbled upon an accessible, everyday-inspired, and wonderfully vegetarian rendition of Tom Kha Gai. This discovery was made possible through the beautiful new cookbook, Love and Lemons Everyday, by my talented friends, Jack and Jeanine. Their approach to vibrant, plant-forward cooking always resonates with me, and this recipe promised to bring the magic of Tom Kha Gai into my home kitchen in a manageable way.
What is Tom Kha Gai? Unpacking the Iconic Thai Coconut Soup
Tom Kha Gai, often simply referred to as Tom Kha, is a highly revered Thai coconut soup that literally translates to “chicken galangal soup.” The “Gai” in its name specifically refers to chicken, while “Kha” denotes galangal, a root similar to ginger but with a more distinct citrusy, piney, and earthy flavor profile. This soup is a testament to the intricate balance found in many Asian dishes, traditionally best prepared fresh to capture its most vibrant flavors.
A classic Tom Kha Gai boasts a rich tapestry of ingredients, each playing a crucial role in creating its signature taste. Key components typically include galangal, aromatic lemongrass, pungent kaffir lime leaves, earthy mushrooms, creamy coconut milk, savory fish sauce, fiery Thai chili peppers, bright lime juice, and fresh cilantro. Together, these elements form an extraordinary representation of Asian cuisine – a perfect harmony and balance of fundamental flavors: heat from the chilies, sweetness from the coconut, sourness from the lime, and saltiness from the fish sauce.
While the traditional version is undeniably sublime, its authenticity often relies on sourcing specific, sometimes hard-to-find ingredients like fresh galangal and kaffir lime leaves, especially outside of specialty Asian markets. This can make recreating it at home a bit of a challenge for the average cook, paving the way for delicious and practical adaptations like the one we’re exploring today.

Therefore, my anticipation for the launch of their second cookbook, Love and Lemons Everyday (affiliate link), had been building ever since Jeanine first shared the exciting news with me.

Crafting Your Own Vegan Thai Coconut Soup: An Approachable Delight
To joyously celebrate the debut of this remarkable cookbook, I am thrilled to share with you their beautifully inventive and intensely flavorful take on Tom Kha Gai soup! While the traditional Thai coconut soup is undoubtedly a culinary masterpiece, its complex ingredient list and reliance on very specific, sometimes exotic, components can make it quite challenging to replicate authentically in a typical home kitchen, particularly in regions like the United States where certain fresh ingredients might be difficult to source.
This is precisely why I adore Jeanine’s ingenious adaptation. It manages to capture the intoxicating fragrance and profound depth of flavor of the original, but in a way that is vastly more accessible and practical for everyday cooking. This vegan Thai coconut soup recipe masterfully incorporates essential traditional ingredients such as rich coconut milk, zesty lime, fresh cilantro, and aromatic lemongrass. Crucially, it smartly substitutes other harder-to-find elements with readily available alternatives, ensuring a remarkably similar and equally delicious flavor profile without the fuss.
What truly elevates her version are the delightful additions of cremini mushrooms, naturally sweet sweet potato, and vibrant chopped kale. While these might not be customary in a classic Tom Kha Gai, they contribute a wonderful heartiness and satisfying texture to the fragrant broth. The sweet potato adds a subtle sweetness and body, while the kale brings a fresh, earthy counterpoint and a boost of nutrients. The result is a soup that is perfectly spicy, incredibly flavorful, and luxuriously creamy thanks to the full-fat coconut milk, all perfectly balanced with just the right amount of tang from freshly squeezed lime juice and zest. It’s a complete meal in a bowl, perfect for a cozy evening.
Serving Suggestions & Customizations for Your Thai Coconut Soup
This exquisite vegan Thai coconut soup is prepared with two cans of full-fat coconut milk, gently diluted with a touch of water, resulting in a wonderfully creamy and relatively thick broth that clings beautifully to the ingredients. Should you prefer a lighter consistency, feel free to adjust the amount of water – the recipe generously allows for up to 3 cups of water in total, giving you flexibility to achieve your desired broth thickness. This versatility ensures the soup can be tailored to your personal preference without sacrificing flavor.
Jeanine, the culinary visionary behind this recipe, offers fantastic recommendations for serving this delightful vegan Tom Kha Gai. She suggests a spoonful of perfectly cooked basmati rice at the bottom of each bowl, which soaks up the flavorful broth beautifully. For garnishes, an abundance of fresh ingredients elevates both the presentation and the taste: crisp lime wedges for an extra burst of acidity, fragrant fresh mint leaves and cilantro for herbaceous notes, and thinly sliced chili peppers for those who love an extra kick. While traditional Thai chilies are ideal, a readily available serrano or red finger chili pepper will work just as wonderfully in a pinch, adding a vibrant heat. Don’t forget a side of tamari or soy sauce for those who like to fine-tune the saltiness to their exact liking.
This soup is not just a meal; it’s an experience. The combination of sweet, savory, spicy, and sour notes, along with the creamy texture and fresh garnishes, makes it incredibly satisfying and memorable. Whether you’re a seasoned vegan chef or simply looking to incorporate more plant-based meals into your routine, this easy Thai coconut soup is a must-try. It’s a comforting, healthy, and exceptionally flavorful dish that proves eating vegan can be anything but boring.

Ingredients
- 2 stalks lemongrass
- 1 teaspoon raw virgin coconut oil
- ½ medium yellow onion thinly sliced
- 12 ounces cremini baby bella mushrooms, stemmed and sliced
- 1 teaspoon kosher salt
- 2 (14-ounce) cans) full-fat coconut milk Aroy-D brand is my favorite brand and Whole Foods 365 Organic is good too
- 1½ cups (360 mL) water or up to 3 cups (720 mL) for a lighter broth
- 1 tablespoon minced fresh ginger
- 2 garlic cloves minced
- 1 large sweet potato chopped
- 1 jalapeno pepper stemmed and diced
- 1 small bunch cilantro (about ½ cup) stems diced and leaves chopped
- zest and juice of 2 limes
- tamari or soy sauce, for seasoning (optional)
- 4 cups loosely packed kale chopped
- 2 cups cooked jasmine rice
- ½ cup fresh mint leaves
- sliced red chile peppers, serrano peppers, or sriracha sauce
Instructions
-
Prepare the lemongrass by cutting off the root end and the tough upper stem of the stalks. Smash the stalks with a rolling pin (*a tenderizer or the side of a wide chef’s knife also works!) to loosen the layers. Pull off the thick outer layers and dice the inner, tender parts. This should yield about ¼ cup chopped lemongrass. Set aside.
-
Heat the oil in a large pot over medium heat. Add the onion, mushrooms, and ½ teaspoon kosher salt and cook, stirring occasionally, for 8 minutes, or until softened.
-
Stir in the lemongrass, coconut milk, 1½ cups water, ginger, garlic, sweet potato, jalapeño, and cilantro stems. If you prefer a lighter broth, add up to 1½ cups more water. Simmer over low heat for 20 minutes, or until the sweet potatoes are fork-tender.
-
Add the lime zest and juice. Taste, then add an additional ½ teaspoon of salt, if desired, and tamari (or soy sauce), if using. Add the chopped kale and simmer just until wilted, 1 to 2 minutes. Stir in the cilantro leaves just before serving.
-
Serve with the rice, fresh mint, cilantro, and chile peppers, if using, and tamari (or soy sauce) on the side.
