Ingredients You’ll Need
This recipe keeps things beautifully simple with ingredients that are easy to find yet crucial in building the depth and freshness that define Lao Chicken Noodle Soup (Khao Piak Sen). Each component brings its own personality to the bowl, from the tender chicken thighs that enrich the broth to the fragrant herbs that brighten every bite.
- 1 lb (450g) bone-in, skinless chicken thighs or breasts: Chicken thighs offer more flavor and juiciness, but breasts work fine too.
- 1 tbsp vegetable oil: For sautéing and locking in the aromatics.
- 1 small onion, diced: Adds sweetness and body to the broth.
- 3–4 garlic cloves, minced: Gives a fragrant punch essential in Lao cooking.
- 1 thumb-sized piece of ginger, sliced: Brings warmth and a subtle zing to the soup.
- 1 stalk lemongrass, smashed (optional but recommended): Imparts a citrusy freshness that’s signature to Khao Piak Sen.
- 6 cups (1.4 liters) chicken broth: Creates a rich and savory base; broth is preferable to water for depth.
- 2 tbsp fish sauce: Adds umami and authentic Southeast Asian flavor.
- 1 tsp sugar (palm sugar if available): Balances savory notes with a touch of sweetness.
- 1–2 tbsp soy sauce: Contributes color and enhances the umami taste.
- 1 tsp ground black pepper: Adds a mild heat and earthiness.
- ½ tsp salt (to taste): Perfectly seasons the broth without overpowering.
- 4 oz (115g) rice noodles (Khao Piak Sen noodles or your favorite rice noodle): The star texture — chewy and slippery noodles that soak up the broth.
- 1 cup fresh cilantro, chopped: Bright and herbaceous garnish that freshens up the finished soup.
- 1 small bunch green onions, sliced: Adds a mild allium flavor and crunch.
- Lime wedges, for serving: Offer a zesty contrast to the savory broth.
- Chili sauce or fresh chili (optional, for heat): Perfect for those who love a spicy kick.
How to Make Lao Chicken Noodle Soup (Khao Piak Sen) Recipe
Step 1: Cook the Chicken
Start by heating vegetable oil in a large pot over medium-high heat. Add the chicken thighs or breasts and sear them for 4 to 5 minutes on each side until they develop a light golden color. This step locks in flavors and textures that make the chicken juicy and tender. Remove the chicken and let it cool enough to shred — this adds body to your soup without losing moisture.
Step 2: Sauté Aromatics
Using the same pot, toss in diced onion, minced garlic, sliced ginger, and smashed lemongrass. Sauté these fragrant aromatics for about 2 to 3 minutes until their scents transform your kitchen with the inviting essence typical of Lao cooking—this builds the flavor foundation of your broth.
Step 3: Simmer the Broth
Pour in the chicken broth, followed by fish sauce, soy sauce, sugar, black pepper, and salt. Stir everything together to marry the flavors. Bring the mixture to a boil, then reduce the heat and let it simmer gently for 15 to 20 minutes. This slow simmer extracts all that wonderful goodness from the aromatics and melds the seasonings perfectly.
Step 4: Cook the Noodles
While the broth skillfully simmers, prepare your rice noodles according to the package—usually boiling for 4 to 5 minutes. Once tender but still bouncy, drain them well and set aside. These noodles are what makes Khao Piak Sen unique, with their wonderfully chewy and slightly slippery texture.
Step 5: Shred the Chicken
Take the cooled chicken and shred it into bite-sized pieces using two forks or your hands. This step helps distribute the chicken evenly throughout the soup, ensuring every bite has just the right amount of tender poultry.
Step 6: Assemble the Soup
Before adding back to the pot, carefully remove the ginger and lemongrass stalk. Add the shredded chicken and cooked noodles to the simmering broth. Allow everything to mingle for about 5 minutes. This final warm-up blends the flavors and allows the noodles to soak up the delicious broth.
Step 7: Serve Your Lao Chicken Noodle Soup (Khao Piak Sen) Recipe
Ladle the steaming soup into bowls and top with freshly chopped cilantro and sliced green onions. Don’t hesitate to jazz it up with optional garnishes like thinly sliced onion, fried garlic, or your favorite chili paste for an extra layer of texture and heat. Serve with lime wedges on the side to squeeze over the top, giving every spoonful a refreshing brightness.

Garnishes
The garnishes are where you can personalize your bowl and add dimension. Fresh cilantro and green onions are classic, but thinly sliced onions, crispy fried garlic, and chili paste elevate the experience. Lime wedges bring a zesty brightness that contrasts beautifully with the rich broth, making each bite refreshing and balanced.
Side Dishes
Lao Chicken Noodle Soup shines as a hearty main, but you can pair it with light, crisp side dishes like a simple Vietnamese-style pickled carrot and daikon salad or steamed greens like bok choy to add freshness and crunch. These sides complement the soup by adding a variety of textures and flavors to your meal.
Creative Ways to Present
For a fun twist, serve the soup family-style with individual garnishes lined up in small bowls so everyone can customize their bowl. You can also add a drizzle of toasted rice powder (khao khua) sprinkled on top for a smoky, nutty flavor that hails from traditional Lao cuisine. For gatherings, a large hot pot version encourages communal eating that’s always a hit.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, transfer the soup to an airtight container and refrigerate. It will keep well for 3 to 4 days. The noodles will absorb some broth overnight, so it might get thicker — you can always loosen it with a splash of water or extra broth when reheating.
Freezing
You can freeze the soup without noodles for longer storage. Keep the broth and shredded chicken in a freezer-safe container for up to 3 months. When ready to enjoy, thaw overnight in the fridge, reheat gently, and cook fresh noodles to add before serving.
Reheating
To reheat, warm the soup on the stove over medium heat until steaming. Then add freshly cooked rice noodles or reheat pre-cooked ones briefly in hot water to restore their texture. Finish with your favorite garnishes and a squeeze of lime for that fresh, vibrant flavor.
FAQs
Can I use chicken breasts instead of thighs?
Absolutely! Chicken breasts will work, but thighs tend to impart more flavor and stay juicy during cooking.
Where can I find Khao Piak Sen noodles?
Specialty Asian markets often carry Khao Piak Sen noodles, but rice noodles or vermicelli can be a good substitute if needed.
Can I make this soup vegetarian?
Yes! Simply replace chicken with tofu and use vegetable broth. You might want to add extra umami elements like mushrooms or soy sauce.
Is lemongrass essential?
While optional, lemongrass adds a citrusy brightness that truly defines the traditional taste of Khao Piak Sen, so try to include it if you can.
How spicy is this soup?
The base soup is mild, but you can always add fresh chili or chili paste to adjust the heat to your liking.
