Thai Rice Soup Recipe: Fragrant Lemongrass Broth With Chewy Grains

This Thai rice soup delivers fragrant comfort in every bowl. A light yet flavorful lemongrass broth cradles chewy rice grains, creating a simple yet deeply satisfying dish.

I developed this recipe to highlight the balance of fresh herbs and subtle spices. The result is a nourishing soup that warms without weighing you down.

Ingredients for Thai Rice Soup

Aromatic herbs and fragrant broth make this soup sing with minimal effort.

The lemongrass is non-negotiable here. Look for firm, pale green stalks at Asian markets or well-stocked supermarkets like Whole Foods. Bruise them with the flat of your knife to release the oils. Fresh ginger and garlic should be plump, not shriveled. I grab mine from the produce section at Trader Joe’s—consistently good quality. The jasmine rice? Any brand works, but rinse it well to remove excess starch.

No fish sauce? Soy sauce plus a pinch of sugar gets you 90% there. Can’t find lime leaves? Lime zest plus a bay leaf works in a pinch. Thai basil is ideal but regular basil or even mint can sub in. The coconut milk adds richness—Chaokoh or Thai Kitchen are reliable brands. Skip the light versions here; you need the full-fat for that velvety texture.

This soup tastes even better the next day as the flavors meld. Keeps 3-4 days in the fridge, freezes for 2 months. Reheat gently to avoid breaking the rice grains. I like to make a double batch and stash half in the freezer for lazy days.

Step-by-Step Instructions for Thai Rice Soup

This method builds layers of flavor that make this dish absolutely irresistible.

Step 1: Toast the Aromatics for Maximum Flavor

Heat the 1 tbsp vegetable oil in a large pot over medium heat. Add the 2 whole lemongrass stalks (bruised and cut into 2-inch pieces), sliced fresh ginger, 4 cloves garlic cloves (smashed), and 2 whole shallots (thinly sliced).

Sauté for 3-4 minutes until the shallots turn translucent and the aromatics release their fragrance. You’ll smell the citrusy lemongrass and warm ginger notes—this is your cue they’re ready. Stir frequently to prevent burning, as the shallots can catch quickly.

Step 2: Build the Broth Base

Pour in the 6 cups chicken broth and add the 4 pieces lime leaves. Bring to a gentle boil, then reduce heat to medium-low. Let it simmer for 10 minutes to allow the flavors to meld deeply.

The broth should turn a light golden hue as the lemongrass and ginger infuse their essence. Skim off any foam that rises to the surface for a clean, clear broth. This step ensures every spoonful is packed with authentic Thai aromatics.

Step 3: Cook the Rice to Chewy Perfection

Add the 1 cup jasmine rice (rinsed until water runs clear) to the simmering broth. Stir well and cook for 15-18 minutes, stirring occasionally, until the rice is tender but still retains a slight chew.

You’ll notice the grains plump up as they absorb the fragrant liquid. Taste a grain to check doneness—it should be soft but not mushy. If the soup thickens too much, add a splash of water to maintain a light, brothy consistency.

Step 4: Finish with Creamy and Bright Elements

Stir in the 1 can coconut milk, 2 tbsp fish sauce, and 1 tsp salt. Simmer for another 5 minutes on low heat to blend the flavors. The coconut milk will mellow the broth’s intensity and add a velvety richness.

Avoid boiling once the coconut milk is added to prevent separation. Taste and adjust seasoning if needed—this is your chance to balance the salty, tangy, and creamy notes perfectly.

Step 5: Add Final Touches and Serve

Remove the pot from heat and stir in the 2 tbsp lime juice and 0.5 tsp red chili flakes. Ladle the soup into bowls and top each serving with 0.5 cup fresh cilantro and 0.25 cup fresh Thai basil.

The herbs should float on top, releasing their fresh, citrusy aroma with every spoonful. Serve immediately while hot—the contrast of warm, creamy broth with the bright, zesty garnishes is what makes this dish shine.
