Ingredients You’ll Need
The beauty of Slow Cooker Tom Kha Soup (Thai Coconut Chicken Soup) lies in its vibrant, yet simple ingredients. Each component plays a crucial role in creating the layer upon layer of classic Thai flavor: from the zesty and herbal aromatics to creamy coconut and savory chicken.
- Chicken: Tender, bite-sized pieces of boneless, skinless chicken breast or thigh soak up all the soup’s flavors.

- Coconut milk: The heart of this soup, delivering a luscious creaminess and signature tropical flavor.
- Lemongrass: Smashed stalks infuse the soup with citrusy brightness and a dash of Thai authenticity.
- Galangal or ginger: Galangal is ideal for its peppery, lemony zing, but fresh ginger adds warmth if that’s what you have.
- Kaffir lime leaves: Torn lime leaves add an aromatic, floral citrus note you can’t get elsewhere.
- Mushrooms: Sliced for earthiness and a little chew, balancing the richness.
- Fish sauce: Just a dash gives the soup its deep, unmistakable umami flavor — don’t skip it!

- Thai red curry paste: A spoonful or two delivers heat and layered spice — add more if you love things fiery!

- Cilantro: Chopped fresh for a herbal lift just before serving.
- Lime wedges: Serve on the side so everyone can add a fresh squeeze to their bowl.
How to Make Slow Cooker Tom Kha Soup (Thai Coconut Chicken Soup)
Step 1: Combine Main Ingredients in the Slow Cooker
Start by adding your chicken pieces, chicken broth, lemongrass, galangal (or ginger), kaffir lime leaves, mushrooms, fish sauce, lime juice, and red curry paste to the slow cooker. Stir everything gently to mingle the amazing aromatics with the chicken and broth. This first step sets the groundwork for that classic Slow Cooker Tom Kha Soup (Thai Coconut Chicken Soup) fragrance, guaranteeing a flavor-packed broth that feels like a warm hug.
Step 2: Cook Low and Slow
Pop the lid on your slow cooker and let it do its magic — set on low for 5 to 6 hours, or high for 2 to 3 hours. As time passes, the chicken turns irresistibly tender and the flavors swirl into a beautiful, creamy base. You’ll notice your kitchen filling with the citrusy, herbal scent of a Thai kitchen!
Step 3: Remove Aromatics
Once the chicken is cooked through and the broth is deeply flavorful, it’s time to fish out the tough lemongrass stalks, galangal slices, and kaffir lime leaves. This simple step ensures a silky-smooth soup with nothing to distract from those delicious spoonfuls.
Step 4: Add Coconut Milk and Tomatoes
Stir in the coconut milk and cherry tomatoes, then cover and let the soup warm through on low for another 15–20 minutes. The coconut milk transforms the broth into something truly magical, and the tomatoes soften just enough to release a little sweetness and color.
Step 5: Taste and Adjust
Give your soup a taste and add extra fish sauce, lime juice, or curry paste if you want more punch or zing. Don’t be shy — customizing is half the fun! Remember, your Slow Cooker Tom Kha Soup (Thai Coconut Chicken Soup) should be bright, creamy, savory, and just the right amount of spicy for you.
Step 6: Garnish and Serve
Ladle the soup into bowls, top with plenty of chopped cilantro and sliced red chili peppers, and nestle a lime wedge alongside each serving. The final pops of freshness and color make every bowl a feast for all the senses.

Side Dishes

Freezing

Reheating
