Description

A creamy, fragrant Thai‑style coconut chicken soup made in a slow cooker, inspired by Tom Kha Gai, combining coconut milk, red curry paste, lime, lemongrass, and tender chicken.


Ingredients

  • 1 lb (≈ 450 g) boneless, skinless chicken breasts (or thighs), cut into bite‑sized pieces
  • 4 cups (≈ 960 ml) chicken broth
  • 1 (14‑oz) can coconut milk (or 400 ml)
  • 2‑3 tbsp Thai red curry paste (adjust to taste)
  • 1 stalk lemongrass, bruised and cut into pieces
  • 1‑2 slices fresh ginger (or galangal), peeled
  • 2 cloves garlic, minced
  • 1 tbsp fish sauce (or to taste)
  • 12 tbsp brown sugar or palm sugar (or to taste)
  • Juice of 12 limes (≈ 23 tbsp)
  • 1 red bell pepper, sliced (optional)
  • 8 oz (≈ 225 g) mushrooms, sliced (optional)
  • Fresh cilantro or green onions, for garnish
  • Salt & pepper, to taste

Instructions

  1. In the slow cooker, combine chicken broth, red curry paste, lemongrass, ginger, garlic, and chicken pieces. Stir to mix well so curry paste dissolves.
  2. Cover and cook on LOW for about 4–5 hours (or HIGH for 2–3 hours) until chicken is nearly cooked and flavors have blended.
  3. Stir in coconut milk, fish sauce, sugar, lime juice, red bell pepper, and mushrooms (if using). Mix thoroughly.
  4. Cover and cook an additional 30–60 minutes on LOW (or 15–30 minutes on HIGH) until vegetables are tender and chicken is cooked through.
  5. Remove lemongrass stalks and ginger slices. Taste and adjust seasoning with more fish sauce, lime juice, or sugar as needed.
  6. Ladle into bowls and garnish with fresh cilantro or green onions. Serve hot.

Notes

  • You can use light coconut milk to reduce fat, though texture may be thinner—if so, whisk in a little cornstarch or tapioca slurry to thicken. (From recipe adaptations) :contentReference[oaicite:0]{index=0}
  • Feel free to swap chicken thighs for more flavor and moisture.
  • Don’t skip bruising the lemongrass and slicing the ginger—they release essential aromatics.
  • If soup seems thin, mix 1 tsp cornstarch with cold water and stir into soup, then cook 10 more minutes to thicken.
  • Leftovers keep in the fridge for about 2–3 days; reheat gently to avoid coconut milk separation.
