Combine the base ingredients in the slow cooker
Now, let’s create the aromatic base of our slow cooker tom kha soup. Begin by adding the chopped white onions, garlic, jalapeño slices, galangal or ginger, lemongrass, lime leaves, red Thai curry paste, and chicken broth into the slow cooker. Give everything a good stir to ensure all those fragrant ingredients are well mixed. This is the moment when your kitchen begins to smell divine!
Let it simmer and develop flavor
Cover the slow cooker with its lid and set it to HIGH for 3 hours or LOW for 6 hours. One of the beauties of slow cooking is the development of flavors, so don’t rush this step. Stir the mixture occasionally, if you’re around, just to see how fabulous it looks!
Add coconut milk and chicken
After the initial cooking time is up, use a slotted spoon to carefully remove the solids, leaving just the liquid behind. Now, it’s time to add in the luscious coconut milk, chicken pieces, and sliced mushrooms. A good stir will wake up the ingredients! Replace the lid and cook on HIGH for another hour or LOW for 2 hours to let the chicken cook through and absorb all those delicious flavors.
Season and adjust flavors before serving
Once the chicken is fully cooked, it’s time to add those final touches. Stir in the brown sugar, fish sauce, and fresh lime juice. Give it a taste—this is where you can adjust the flavors to your liking. Maybe you want it a tad sweeter, or perhaps a splash more lime juice for that zing?
Serve your slow cooker tom kha soup in bowls, and don’t forget to garnish with fresh herbs like green onions and cilantro for a lovely finish. Enjoy a bowl of warmth that encapsulates the zest of Thai cuisine right at home!

Variations on Slow Cooker Tom Kha Soup
Vegetarian Tom Kha Soup Option
Craving a creamy, aromatic bowl of Tom Kha soup but want to skip the meat? No problem!

Whether you choose the vegetarian version or opt for shrimp, you'll be enjoying a comforting bowl of this Thai classic that’s perfect for any occasion.
