Crafting your delicious Thai Chicken Soup is easy when you follow these steps:

1. Cook the Chicken: In a pot, bring the chicken broth to a gentle simmer. Add the chicken breasts or thighs and cook for about 15 minutes, or until the chicken is fully cooked.
2. Remove and Shred Chicken: Once cooked, remove the chicken from the pot and let it cool. Shred into bite-sized pieces and set aside.
3. Create the Base: To the broth, add the minced lemongrass, sliced galangal, and torn kaffir lime leaves. Simmer for another 5-10 minutes to infuse the flavors.
4. Add Coconut Milk: Pour in the coconut milk and stir well to combine. Allow the mixture to heat through.
5. Incorporate Vegetables: Add the sliced mushrooms and halved cherry tomatoes to the pot. Cook for about 5 minutes until the mushrooms are tender.
6. Add Chicken and Seasoning: Return the shredded chicken to the soup and stir in the fish sauce and lime juice. Adjust seasoning with salt and pepper as needed.
7. Finish with Greens: Stir in the spinach or Thai basil until just wilted.
8. Serve Hot: Ladle the soup into bowls and garnish with fresh cilantro before serving.

By following these straightforward steps, you’ll have a delicious bowl of Thai Chicken Soup ready in no time!
