Thai Chicken and Rice Soup Recipe: Aromatic Lemongrass and Coconut Broth

This Thai-inspired soup brings together tender chicken, fragrant rice, and a rich coconut-lemon broth that warms you from the inside out. The secret lies in the balance of fresh herbs and aromatic spices that create depth without complexity.

I’ve refined this recipe to ensure every spoonful delivers bold Thai flavors with minimal effort. The broth, infused with lemongrass and ginger, forms the heart of the dish, while coconut milk adds a velvety finish.

What sets this apart is its simplicity—no hard-to-find ingredients, just authentic taste built layer by layer. The chicken stays juicy, the rice soaks up the broth, and the herbs brighten every bite.

Perfect for chilly evenings or when you crave something comforting yet light. Here’s how to make it.

Ingredients for Thai Chicken and Rice Soup

A handful of fresh ingredients and pantry staples create this aromatic, comforting bowl.

The lemongrass and ginger are non-negotiable here. Find them fresh at Asian markets or the produce section of well-stocked grocery stores. Look for firm stalks with tight layers—avoid anything dried out or woody. Thai Kitchen and Maesri make solid red curry pastes if you can’t find a specialty brand. The coconut milk should be full-fat; light versions won’t give you that rich, velvety texture.

No fresh lemongrass? Lemongrass paste at half the amount works in a pinch (find it in tubes near the herbs). Fish sauce can be swapped for soy sauce or tamari if needed, though the flavor profile changes slightly. Brown sugar not on hand? White sugar or honey will do. For extra depth, add a splash of coconut aminos—it’s like a cross between soy sauce and fish sauce.

The soup tastes even better the next day once the flavors meld. Stores in the fridge for 3-4 days or freezes for 3 months. Reheat gently on the stove—microwaving can separate the coconut milk. Always add fresh cilantro and lime just before serving.

Step-by-Step Instructions for Thai Chicken and Rice Soup

This method ensures a perfectly balanced broth with tender chicken and fragrant rice every time.

Step 1: Prepare the Aromatic Base

Heat the 1 tbsp Vegetable Oil in a large pot over medium heat. Add the 2 tbsp Red Curry Paste and stir for 1-2 minutes until fragrant. This step wakes up the spices and creates a flavor foundation for the soup.

Add the 1 tbsp Fresh Ginger, 4 cloves Garlic Cloves, and 2 pieces Lemongrass. Sauté for 2-3 minutes until the aromatics soften slightly. You’ll notice the kitchen filling with an intoxicating aroma—that’s how you know it’s working.

Step 2: Build the Broth

Pour in the 4 cups Chicken Broth and 1 can Coconut Milk. Stir well to combine, breaking up any clumps of curry paste. The coconut milk will separate initially but will incorporate as it heats.

Add the 1 tsp Brown Sugar, 1 tsp Salt, and 2 tbsp Fish Sauce. Bring the mixture to a gentle simmer over medium-high heat, then reduce to medium-low to maintain a steady, gentle bubble. Let it cook for 10 minutes to meld the flavors.

Step 3: Cook the Chicken and Rice

Add the 1 lb Boneless Chicken Breast (thinly sliced) to the simmering broth. The chicken will cook quickly—5-7 minutes is all it needs. You’ll see the pieces turn opaque and firm up as they cook through.

Stir in the 1 cup Jasmine Rice and cook for 15-18 minutes until the rice is tender and the chicken is fully cooked. The rice should absorb much of the liquid, creating a creamy, porridge-like consistency.

Step 4: Finish with Bright Flavors

Remove the pot from heat. Stir in the juice from the 1 whole Lime—this adds a bright, citrusy note that balances the richness of the coconut milk. Taste and adjust seasoning if needed, adding more fish sauce for saltiness or lime for acidity.

Ladle the soup into bowls and garnish each serving with 0.5 cup Fresh Cilantro and 0.25 cup Green Onions. The fresh herbs add a pop of color and a fresh, vibrant finish that ties the whole dish together.

Make-Ahead Tips for thai chicken and rice soup

Prep Ahead Strategy

Chop all aromatics—lemongrass, ginger, and garlic—the night before and store in an airtight container in the fridge. This saves 10 minutes of prep time on cooking day. 💡

Broth Infusion

Simmer the broth with lemongrass and ginger up to 24 hours ahead. The flavors deepen overnight, making your soup even more aromatic. I do this when I know I’ll be short on time.

Rice Cooking Tip

Par-cook the jasmine rice for 10 minutes and refrigerate it. On serving day, add it to the hot broth to finish cooking. This prevents mushy rice and cuts active prep time in half.

Chicken Prep

Slice the chicken breast thinly and marinate in 1 tbsp fish sauce and 1 tsp lime juice for up to 4 hours in the fridge. This keeps it moist and flavorful when reheated. 🍗

Freezing Instructions

Cool the soup completely before freezing in quart-sized bags for up to 3 months. Lay flat to save space. Thaw overnight in the fridge before reheating gently on the stove.

Garnish Separately

Store cilantro and green onions separately and add fresh when serving. This keeps them crisp and vibrant. I always prep these last for the best texture.
