This slow cooker version of my best-ever tom kha soup recipe (or Thai coconut chicken soup) is absolutely perfect… and made to be easier than ever! Light, yet filling and full of tangy flavor, it’s the best tom kha gai recipe I’ve ever made or tried and is so creamy, easy, and delicious.

– Made from red chilis, this paste is a little sweet, spicy, and savory and adds a major punch of flavor to your Crockpot tom kha gai.

Kaffir lime leaves are traditional to Thai cooking and add a delicious citrus and floral aroma.

Galangal is citrusy, while ginger is sharp and spicy. If you can’t find galangal, ginger will work just fine.

Citrusy and tangy, lemongrass gives the slow cooker tom kha gai a lemony, minty flavor.

– Rich, sweet, and creamy, coconut milk or cream makes this tom kha light, filling, and full of flavor.
