Asian Udon Noodle Soup (Khaub Piaj or Khao Piak Sen)
This soup is a Hmong and Laotian dish. It is call Khaub piaj or khao piak sen. It’s similar to chicken noodle soup. The noodles are made fresh using rice flour and tapioca starch. It is soft and chewy. This soup is perfect for the cold weather, but I still make it during the spring/summer when I want to eat it too.
To make the noodles, you’ll need:
- 1 cup Rice Flour (Red bag)
- 2 cups Tapioca Starch (Blue bag)
- About 1 1/4 cups of boiling water
You can find these flours at any Asian grocery stores. Or you can buy it from Amazon. It cost more, but it’s free shipping.
In a stand mixer, pour in both of the flours. Add 1 cup of boiling water and mix. Then add 1/2 cup of water. Still mixing. Add a little bit of water at a time. If it is too dry, add more water. If it is stick, add a little bit of tapioca starch. When the mixture is in a lumpy dough form, take it out of the stand mixer. Divide the dough into thirds.
Using some tapioca starch to dust, roll 1/3 of the dough until it is 1/8 inch thick. Cut it into 1/4 inch thick or depending on how thick you like your noodles. Then dust the noodles in tapioca starch to prevent it from sticking to each other.
To make the broth, you’ll need:
- 2 cups shredded cook chicken
- 48 oz chicken stock
- 1 stalk lemongrass
- Salt, to taste
- Pepper, to taste
- Fish sauce, to taste
- 1-2 cups of water if needed
When the water is boiling, add noodles in. Stir the noodles to keep it from sticking to the bottom of the pot. You’ll know when the noodles are ready when they float to the top and the liquid thickens.
Cut green onions, cilantro, and limes to garnish.
These are the Asian sauces that I like to put in my soup: chili oil, hoisin sauce, Sriracha sauce, and soy sauce. I also add black pepper.
It’s totally up to you how you season your soup since everyone has different taste. For example, I like mine spicy and sour while my husband prefer his to have more hoisin and soy sauce. You can experiment with any sauces and adjust it to your taste.
Enjoy!
