30-Min Seafood Hot and Sour Soup Recipe

Seafood Hot and Sour Soup is one of my favorite Chinese soups to make when I want something warm, comforting, and packed with flavor. Tender shrimp, sweet scallops, earthy mushrooms, silky tofu, and delicate egg ribbons come together in a rich broth that’s both tangy and peppery.

The first time most people try hot and sour soup, they’re surprised by how many layers of flavor it has. The vinegar adds brightness, the white pepper brings gentle heat, and the mushrooms, seafood, and chicken stock create a deep savory flavor that keeps you coming back for another spoonful.

One of the best things about making hot and sour soup at home is that you can control every ingredient. You can make it milder or spicier, add more seafood, adjust the tanginess, or use whatever vegetables you have on hand.

In this recipe, I’ll show you how to make Seafood Hot and Sour Soup with tender seafood, silky egg ribbons, and the perfect balance of hot and sour flavors in about 30 minutes.

What Is Hot and Sour Soup?

Hot and Sour Soup is a classic Chinese soup known for its bold, tangy, and slightly spicy flavor. The “hot” comes from white pepper, while the “sour” comes from vinegar.

Traditional versions often include mushrooms, tofu, bamboo shoots, eggs, and a protein such as pork, chicken, or seafood. The broth is lightly thickened with cornstarch, giving it a silky texture that helps carry all the flavors throughout the soup.

There are many regional variations, but the combination of vinegar and white pepper is what gives hot and sour soup its signature taste.

What Makes Hot and Sour Soup Hot and Sour?

This is one of the most common questions people ask.

The Sour Flavor

The sour flavor comes primarily from Chinkiang vinegar, a Chinese black vinegar with a rich, slightly smoky flavor.

Compared to rice vinegar, Chinkiang vinegar adds more depth and complexity to the soup.

The Hot Flavor

Unlike many spicy soups, the heat in hot and sour soup comes from white pepper rather than chili peppers.

White pepper provides a gentle warmth that builds gradually without overpowering the other ingredients.

The balance between the vinegar and white pepper is what makes hot and sour soup so unique.

Why Add the Vinegar at the End?

One of the small techniques that makes a big difference is adding the vinegar near the end of cooking.

When vinegar is boiled for too long, some of its sharpness fades.

Adding the second seasoning near the end helps preserve the bright, tangy flavor that makes hot and sour soup so delicious.

This is the same reason the sesame oil is added at the end as well.

How to Make Silky Egg Ribbons

One of the most recognizable features of hot and sour soup is the delicate egg ribbons floating throughout the broth.

To create them:

• Bring the soup to a gentle boil.
• Slowly drizzle in the beaten eggs.
• Pour in a thin stream while moving around the pot.
• Allow the eggs to set for a few seconds.
• Gently stir once or twice.

How to Thicken Hot and Sour Soup

Traditional hot and sour soup should be lightly thickened, not overly thick or gelatinous.

The cornstarch slurry helps:

• Give the broth body
• Suspend the ingredients evenly
• Create a silky mouthfeel
• Help the flavors cling to each spoonful

Always stir the slurry before adding it to prevent the cornstarch from settling.

Let’s Talk Ingredients

Shrimp and Scallops: Shrimp and scallops add natural sweetness and turn this into a hearty seafood version of hot and sour soup.

Chinkiang Vinegar: This Chinese black vinegar provides the signature sour flavor and deep complexity.

White Pepper: White pepper creates the classic warming heat that gives hot and sour soup its name.

Shiitake Mushrooms: Shiitake mushrooms add an earthy, savory flavor to the broth.

Wood Ear Mushrooms: Wood ear mushrooms contribute a slightly crunchy texture that’s commonly found in restaurant-style hot and sour soup.

Tofu: Soft tofu adds a silky texture and absorbs the flavors of the broth beautifully.

Cornstarch Slurry: The slurry lightly thickens the soup, creating the signature silky consistency.

Chicken Stock: A good-quality chicken stock forms the flavorful foundation of the soup.

Step-by-Step: Let’s Cook

Serves: 4
Prep Time: 15 minutes
Cook Time: 15 minutes

Step 1: Season the Seafood

In a bowl, combine the shrimp and scallops with the salt and white pepper. Mix gently and set aside.

Tip: Seasoning the seafood first helps build flavor from the beginning.

Step 2: Mix the Seasonings

In a small bowl, combine the soy sauce and salt.

In another bowl, combine the Chinkiang vinegar, white pepper, dark soy sauce, and sesame oil.

Tip: We add the vinegar mixture later so it keeps its bright, tangy flavor.

Step 3: Cook the Vegetables

In a large pot over high heat, bring the chicken stock to a boil.

Add the first seasoning, shiitake mushrooms, wood ear mushrooms, bamboo shoots, carrot, and ginger. Boil for about 4 minutes until the vegetables begin to soften.

Tip: Cooking the vegetables first allows them to flavor the broth.

Step 4: Add the Seafood and Tofu

Add the tofu, shrimp, and scallops.

Boil for about 1 minute until the seafood is nearly cooked through.

Tip: The seafood cooks quickly and will continue cooking in the hot broth.

Step 5: Thicken the Soup

Stir the cornstarch slurry to recombine.

Slowly pour it into the soup while stirring.

Cook until the broth is lightly thickened.

Tip: A properly mixed slurry creates the silky texture that hot and sour soup is known for.

Step 6: Finish the Soup

Add the second seasoning and bring the soup back to a boil.

Slowly drizzle in the beaten eggs in a circular motion. Let the eggs set for a few seconds before gently stirring.

Garnish with the scallions and serve hot.

Tip: Pouring the eggs slowly creates delicate egg ribbons throughout the soup.
