Creating Easy Thai Chicken Soup is simple. Follow these steps for a delicious outcome:

1. Cook the Chicken: In a pot, add the chicken breast and cover it with water. Bring to a boil and cook for about 15 minutes, or until cooked through. Remove and shred the chicken once it’s cool.
2. Prepare the Broth: In the same pot, pour in the chicken broth and coconut milk. Bring to a simmer over medium heat.
3. Add Curry Paste: Stir in the red curry paste, mixing well until it dissolves completely in the broth.
4. Flavor with Fish Sauce: Add the fish sauce to enhance the soup’s savory profile, then bring the mixture to a gentle boil.
5. Incorporate Vegetables: Add the sliced mushrooms to the pot and let them cook for about 5 minutes, or until tender.
6. Finish with Greens: Stir in the shredded chicken, followed by the chopped spinach or cilantro. Allow everything to cook for another 2-3 minutes.
7. Taste and Adjust: Give your soup a taste and adjust the seasoning if necessary, adding more fish sauce or curry paste based on your preference.
