This tantalizingSuan La Fen, or as we’re calling it in English,Chongqing Hot and Sour Glass Noodle Soup (酸辣粉 – suān là fěn), has the same beloved status in China as the Hot and Sour Soup we know here in the U.S.
The fact that there are instant noodle versions of this noodle soup should indicate just how popular it is. But making this dish at home will be infinitely better than any instant version!
Also, bonus: this recipe is vegan/vegetarian. But for you meat-lovers out there, you won’t miss the meat at all!
What Is Suan La Fen?
Suān là fěn (酸辣粉), or Chongqing Hot and Sour Glass Noodle Soup, consists of a soup base layered with spicy, numbing, sour, and umami flavors, along with glass noodles and many colorful condiments. The result is a slippery, silky and crunchy texture, with little bursts of competing and complementary flavors.
Traditionally, the noodles in this dish involve a sweet sweet potato starch batter extruded through holes in a device similar to a sifter/colander. The batter “runs” directly into boiling water, which is how vendors shape and cook the noodles.
For convenience, we’re going to use a Korean brand of sweet potato glass noodles that are already ready to go!
Noodle Soup in Summer?
So why am I asking you to make this Hot and Sour Glass Noodle Soup in the middle of the summer? Well, summer is the season we indulge in a lot of raw foods, like chilled fruits and salads. We also seek the comfort of air conditioning, and the cooling effects of iced treats and drinks.
According to traditional Chinese medicine, all of that cooling can bring on dampness (湿气 – shī qì), which can cause weakness.
We all hate being sweaty and sticky in the summertime, but sweating is the quickest way to get rid of dampness. Just think, people from hot and humid places like Southeast Asia are still keen on eating spicy, sour foods––and noodle soups!
Chongqing in Sichuan Province is known for its dampness and humidity. It’s cuisine is also very heavily spiced. Hot pot, anyone?
This Chongqing Hot and Sour Glass Noodle Soup will definitely make you sweat a bit, and it’s all good!
I certainly look to protect myself from dampness during the summer months, and always remind my girls to do the same. My TCM doctor during our stay in Beijing, Dr. Shao, told me that her mother (a retired TCM doctor herself), doesn’t use fans or air conditioning in their home, no matter how hot it is. I know it seems extreme, and but the main message is…it’s okay to sweat sometimes!
Back to the recipe though, this tasty hot and sour glass noodle soup has a strong, “in your face” kind of personality. No wishy washy flavors here. It’s delicious, spicy, tangy, and satisfying. That said, feel free to adjust any of the flavors here to your own liking. On to the recipe!

Suan La Fen Recipe Instructions
It’s easiest to use store-bought roasted soybeans or peanuts. However, you can also use dried soybeans and roast them yourself. Start by soaking them for at least 3 hours. Drain thoroughly.
Over low heat, add a few tablespoons of vegetable oil. Wok-fry the soaked soybeans for at least 15 minutes, until fragrant and nutty. Remove from the wok and set aside to cool completely. (Leave any remaining oil in the wok behind to cook the rest of the dish.) If wok-frying peanuts, follow these instructions for traditional Wok Roasted Peanuts.
Bring a pot of water to a boil, and cook the noodles according to package instructions. Some brands may require you to soak the noodles overnight, but you can simply boil them until relatively tender (they’ll still be chewy). Once cooked, drain and rinse in cold running water. Set aside.
Heat your stock in a separate pot. Keep it at a low simmer. If you don’t have stock, you can use hot boiling water.
To the bottom of your noodle bowl, add the ginger, garlic, sesame seeds, and pepper flakes.
Heat 3 tablespoons oil until it’s shimmering and smoking lightly, and pour over the ingredients in the soup bowl. They’ll sizzle and become fragrant!
Stir the sizzling ingredients, and add the vinegar, soy sauces, sugar, Sichuan peppercorn powder, white pepper, sesame oil, and chili oil.
Pour the hot stock into the bowl, and mix well.
Add the cooked noodles, and top with the pickled mustard stems, scallions, cilantro, and roasted soybeans/peanuts. Taste for seasoning and adjust if needed. Serve!

Instructions
You can use store-bought roasted soybeans or peanuts, but if using dried soybeans like I did, soak them for at least 3 hours and drain thoroughly. Over low heat, add a few tablespoons of vegetable oil, and wok-fry the soaked soybeans for at least 15 minutes, until fragrant and nutty. Remove from the wok and set aside to cool completely (leave any remaining oil in the wok behind to cook the rest of the dish). If wok-frying peanuts, follow these instructions for traditional Wok Roasted Peanuts.
Bring a pot of water to a boil, and cook the noodles according to package instructions. Some brands may require you to soak the noodles overnight, but you can simply boil them until relatively tender (they’ll still be chewy). Once cooked, drain and rinse in cold running water. Set aside.
Heat your stock in a separate pot. Keep it at a low simmer. If you don’t have stock, you can use hot boiling water.
To the bottom of your noodle bowl, add the ginger, garlic, sesame seeds, and pepper flakes. Heat 3 tablespoons oil until it’s shimmering and smoking lightly, and pour over the ingredients in the soup bowl. They’ll sizzle and become fragrant!
Stir the sizzling ingredients, and add the vinegar, soy sauces, sugar, Sichuan peppercorn powder, white pepper, sesame oil, and chili oil.
Pour the hot stock into the bowl, and mix well. Add the cooked noodles, and top with the pickled mustard stems, scallions, cilantro, and roasted soybeans/peanuts. Taste for seasoning and adjust if needed. Serve!
Tips & Notes:
Note: Prep time does not include optional step of roasting soybeans/peanuts.
