This Thai Chicken Soup recipe is so easy, delicious, and hearty. Made with easy to find ingredients, this soup tastes luxurious with as much or as little heat as you want. Complex flavors from fresh ginger, bright lemon or lemongrass (whichever is easy to find), warm red curry paste and silky coconut milk. The chicken cooks to perfection, plus mushrooms and carrots add excellent texture and fresh flavor.

Ingredients in Thai Chicken Soup-
Boneless Chicken Breasts- Two chicken breasts is the perfect amount if you also like a good helping of broth, but you could add up to three breasts if you want more bites of chicken in the soup.
Onions, garlic, and ginger- These ingredients are the aromatics in the soup. Mixed with just a bit of oil and then heated in the microwave before placing into the slow cooker helps to release as much flavor as possible.
Carrots and mushrooms- The carrots become perfectly tender and flavorful while cooking in the slow cooker and the mushrooms do best added at the end to retain their tenderness.
Chicken broth and coconut milk- The coconut milk add the creamy factor and a tiny bit of sweetness inherent in coconuts (buy unsweetened coconut milk).
Fish sauce, cilantro, red curry paste, salt and pepper- The fish sauce adds great depth but can be left out if you don’t like it. You can replace it with soy sauce to replace a little bit of the umami that is very important here. Fresh cilantro stems are tied together and placed in the slow cooker to be removed at the end so you get the fresh herby tang from cilantro. Red curry paste doesn’t add heat but is rich and bold.
Fresh lemon zest or lemongrass- Lemongrass or fresh lemon zest add the brightness that brings all the other flavors front and center. Either one works well, so add whatever you have or is easy to find.
Scallions, jalapeños, limes, and chili oil for topping- If you want more fresh taste and texture, adding fresh scallions and lime juice just before serving takes care of that. And if you want a little or a lot of heat, sliced jalapeños and chili oil pair so well with this soup. My husband doesn’t love heat but he still adds a bit of the chili oil and it’s just right.
How to make Thai Chicken Soup-
Before placing everything in the slow cooker heat the chopped onion, grated ginger, and minced garlic in the microwave for a few minutes to let the ingredients soften. This helps the aromatics release as much flavor as possible. Then place this mixture in the slow cooker.

Add chicken broth, coconut milk, fish sauce, chopped carrots, a cilantro bouquet, and two whole boneless chicken breasts. Cook these ingredients on low for four to six hours.

Remove the chicken breasts to a cutting board and let cool while you add the sliced mushrooms to the slow cooker and turn the heat up to high for fifteen minutes. Adding the mushrooms at the end gives them time to absorb some great flavor without becoming rubbery from absorbing too much liquid. Then heat and add the second can of coconut milk, shred the chicken and add it back to the pot to heat for a couple minutes.
The chicken is perfectly tender, the bold flavors from the curry paste, lemon zest and fish sauce blend well with the onions, garlic, and ginger. Different textures from the carrots, mushrooms, and garnishes bring everything home for a unique comfort food meal. Top with chopped scallions, then add some sliced jalapeños and a drizzle of chili oil if you want heat. This soup is so tasty and looks pretty.
The soup is a great all in one meal that requires no accompaniments, but you could heat up some frozen edamame pods and top with a good dash of chunky salt to enjoy with the soup. Also, easily made vegetarian, leave out the chicken and either just increase the vegetables, or add large chunks of extra firm tofu at the end, replace the chicken broth with vegetable broth and omit the fish sauce or use vegan fish sauce.

This recipe speaks to my heart. I love Thai recipes. Can’t wait to make this one!
Sounds delish and I’m making this for supper tonight!
My wife and I will enjoy this but we need to know how many carbs are in this.
Tevrah, I’m sorry I don’t know. It doesn’t have many carb ingredients and most of the carbs should come from the chicken in this recipe. I don’t track this information closely. I just try to cook with a balance of fresh and healthy real food (most of the time).
