I like to say the quality of an Asian buffet is measured by its hot and sour soup.

Hot and sour soup is the first thing I go for as a palate cleanser. If it’s tasty, chances are the rest of the buffet is going to be pretty awesome too.

When making it at home, I have to admit, I love using those little instant soup packets. It’s great for making a single serving or a small portion.

But it’s actually not that hard to make hot and sour soup from scratch at home, and you get a much bigger pot to feed a crowd.

What is Chinese Hot and Sour Soup?

If you’ve ever been to an Asian buffet, chances are you’ve come across hot and sour soup. It’s a savory, tangy soup with plenty of texture. It has just the right balance of sour, spicy, slightly sweet, and savory.

The broth is dark and lightly thickened with a cornstarch slurry. The hot (referring to the heat) comes from red chili flakes, and the sour comes from vinegar.

The soup is usually loaded with goodies: silky egg ribbons, tiny cubes or thin strands of tofu, and crunchy wood ear mushrooms. Shiitake mushrooms are also sometimes added for extra earthy flavor.

The broth can be made with just about any stock, including vegetable, pork, beef, or chicken, depending on what you have on hand.

Ingredients for Chinese Hot and Sour Soup

What You Will Need

To make Chinese hot and sour soup at home, gather the following ingredients:

The Broth: I usually have homemade chicken stock on hand, made by pressure cooking or simmering chicken bones on the stovetop with plenty of bulb onions and ginger. You can also use lightly salted store-bought chicken or vegetable stock, or bone broth. Store-bought American stock usually doesn’t contain ginger, so let it simmer with a bit of ginger to give it that classic Asian chicken stock flavor. Don’t have chicken stock on hand? Sub with water and some chicken bouillon powder and MSG. You’re welcome.
Mushrooms: Wood ear mushrooms for that essential crunch and shiitake mushrooms for extra earthy flavor. I love using the dried versions for both as they are nonperishable.
Bamboo Shoots: I like to use canned julienned bamboo shoots for convenience.
Tofu: Choose firm or medium-firm tofu. Cut it into thin sheets, then into matchsticks.
Eggs: Beaten eggs for those beautiful ribbons.
The Seasonings: Light soy sauce, dark soy sauce for color, ground white pepper, salt, sugar and toasted sesame oil.
Red Pepper Flakes: Traditionally, red pepper flakes provide the heat, and so does the ground white pepper. If you don’t have dried chili flakes, sub with minced fresh red chilies.
Vinegar: The sour component. I’m using white vinegar here, but if you can get your hands on Chinese black vinegar, it would be more traditional.
Thickener: Cornstarch mixed with a bit of cold water to create a slurry. This is used to lightly thicken the soup.
Garnishes: Thinly sliced green onions. You can also use thinly sliced cilantro or a combination of both and plenty of ground white pepper to top the soup. You can also sub with ground black pepper.

How to Make it

Step 1: Prepare the ingredients

Start by rehydrating the wood ear and shiitake mushrooms by soaking them in hot water. This will take about 15 minutes. The hotter the water, the quicker they will hydrate. Once softened, finely mince the wood ear mushrooms and thinly slice the shiitake mushrooms.

Drain the bamboo shoots and give them a good rinse with hot water to remove the strong aroma. Drain and cut the tofu into thin matchsticks or tiny cubes. Finally, thinly slice the green onions with whites and greens separated.

Step 2: Make the broth

In a medium pot, bring the stock to a gentle simmer over medium heat. Add the bamboo shoots, tofu, wood ear mushrooms, shiitake mushrooms, and the white parts of the green onions. Simmer on medium-low for about 10 minutes to allow the flavors to meld together.

Step 3: Season the broth

Stir in the light soy sauce, dark soy sauce, vinegar, sugar, white pepper, and sesame oil.

Step 4: Thicken the broth

Make the corn starch slurry by mixing it with cold water until it fully dissolves. Slowly drizzle the slurry into the simmering soup while stirring in a circular motion. Cook for 1 minute until the broth turns glossy and thickens.

Step 5: Create egg ribbons

Turn off the heat completely. Hold the bowl of beaten eggs a few inches above the pot and slowly stream the eggs in while stirring the soup in one circular direction.

Step 6: Finish and serve

Ladle into bowls and garnish with green onions, cilantro, and ground pepper.

Pro Tips

Thicken before adding the egg: The cornstarch-thickened broth helps suspend the egg, creating those beautiful, soft restaurant-style ribbons.
Avoid double-dipping when tasting: Double dipping is gross but here it will break down the soup and ruin its thick and velvety texture. Use a clean spoon each time you taste!
Add protein to make it heartier: Thinly sliced beef or pork are great additions if you want to turn this into a heartier soup.

Storage & Reheating

This makes about 7-8 servings, so you’ll most likely have leftovers. Keep the soup in the pot, cover, and store it in the refrigerator.

To reheat, gently warm the soup on the stovetop over medium-low heat, stirring occasionally, until heated through.

For individual portions, you can also microwave the soup in a covered, microwave-safe bowl for about 2 minutes.
