Step‑by‑Step Instructions for Hot and Sour Noodle Soup
Step 1: Prepare Meat Topping (Optional)
In a skillet, heat 2 tablespoons of peanut oil over medium-high heat. Add 200 grams of ground pork and cook for about 4-5 minutes, stirring frequently until it turns golden brown. Stir in 1 tablespoon of Shaoxing wine, followed by 2 teaspoons of dark soy sauce and 2 teaspoons of Sui Mi Ya Cai (if using). Cook for another 2 minutes until the sauce is absorbed, then set the pork aside.
Step 2: Make Broth
In a medium saucepan, combine 4 cups of chicken broth, 2 tablespoons of Chinkiang vinegar, 1 tablespoon of light soy sauce, and a pinch of sugar. Bring this mixture to a boil over medium heat, stirring occasionally. Once boiling, lower the heat and let it simmer for about 10 minutes, allowing the flavors to meld beautifully for your Hot and Sour Noodle Soup.
Step 3: Prepare Noodles
While the broth is simmering, bring a pot of water to boil over high heat. Add 200 grams of fresh sweet potato noodles and cook according to package instructions, usually about 3-5 minutes, until they are al dente. Once done, quickly drain and rinse the noodles under cold water to halt the cooking process, ensuring they remain springy and perfect for your soup.
Step 4: Assemble
In deep serving bowls, ladle the hot broth. Add a portion of the cooked sweet potato noodles to each bowl, followed by the optional pork topping if using. Then, generously sprinkle with roasted peanuts and chopped cilantro or green onions for garnish. For an extra kick, drizzle with chili oil and serve immediately, enjoying the delightful flavors of your hot and sour noodle soup.

Hot and Sour Noodle Soup Recipe FAQs
How do I select the right noodles for Hot and Sour Noodle Soup?
Absolutely! For the best results in your Hot and Sour Noodle Soup, choose fresh sweet potato noodles if available. They offer a unique chewy texture that complements the rich broth. If you can’t find them, dried sweet potato or even potato noodles are great alternatives. Just be sure to follow the package instructions for cooking times to achieve the perfect al dente consistency.
What’s the best way to store leftover soup?
Very good question! Store any leftover Hot and Sour Noodle Soup in an airtight container in the refrigerator for up to 3 days. To maintain the texture of the noodles, it’s advisable to keep the noodles and broth separate. If you’ve mixed them already, just be aware that the noodles may absorb some broth and become softer.
Can I freeze Hot and Sour Noodle Soup?
Sure thing! You can freeze the broth for up to 2 months in airtight containers. Just let the broth cool completely before sealing it up. It’s best to avoid freezing cooked noodles because they will become mushy once thawed. Instead, when you’re ready to enjoy a warm bowl, simply reheat the broth on the stove and prepare fresh noodles for the perfect meal.
What if I have allergies to any of the ingredients?
That’s a thoughtful consideration! If you have food allergies, the beauty of this Hot and Sour Noodle Soup recipe is its versatility. You can easily adapt it by omitting or substituting ingredients like ground pork (with sautéed mushrooms or textured vegetable protein) and using gluten-free soy sauce or tamari for a gluten-free diet. Always check labels for hidden allergens and feel free to get creative with other toppings that suit your dietary needs!
Why does my broth taste bland?
I hear you! A bland broth can be disappointing. Make sure to use high-quality broth as your base. If your broth lacks flavor, consider increasing the soy sauce or vinegar to enhance the depth. A pinch of sugar can also balance out the flavors beautifully. Don’t hesitate to make adjustments according to your taste; that’s the secret to a remarkable Hot and Sour Noodle Soup!
Can I prepare the broth in advance?
Absolutely! Preparing the broth ahead of time is a fantastic idea. You can make it a day or two in advance, refrigerating it for up to 3 days. This allows the flavors to meld beautifully, giving you an even richer taste when you’re ready to enjoy the soup. Just reheat it on the stove before adding your fresh noodles and toppings!
