Chinese Hot and Sour Soup with Tofu and Vegetables Recipe
Classic Chinese hot and sour soup is a bit like an Asian version of Polish sour cucumber soup – it warms you up, stimulates the appetite, and does a great job waking you up after a long day. In China it’s often served in small bowls as a side to lunch or dinner, but it can easily be a light supper on its own. The version with tofu and vegetables is milder, and you can easily adjust the heat level to your taste.
Suan la tang is popular in Sichuan and northern China, where hot and sour soups are meant to warm you up in a cooler climate. Restaurant versions often include wood ear mushrooms, bamboo shoots, and pork, while home-style versions usually simplify the ingredient list.
This is a lighter, vegetable-forward version of classic Chinese hot and sour soup that keeps the characteristic balance of sourness and heat without being heavy. Thanks to tofu and plenty of vegetables, it’s filling yet still light, and the level of spiciness and sourness is easy to adjust to your own taste.
Why this version works
- The simplified ingredients are easy to find in a supermarket while keeping an authentic hot‑and‑sour flavor profile.
- Thickening with starch at a gentle simmer gives a smooth, velvety texture without lumps.
- Pouring the egg in a thin stream over low heat creates delicate ribbons instead of omelet-like chunks.
Chef's tips
Prepare all the ingredients before you start cooking – the soup itself comes together quickly, and it’s easier when everything is chopped and ready. Taste at each stage of seasoning with vinegar, soy sauce, and chili; this soup is all about balance, so adjust gradually. If you’re using dried mushrooms, don’t forget to add some of the soaking liquid to the pot for extra depth of flavor (strain it first to remove any grit).
How to serve
Serve the soup very hot in small bowls as a starter or in larger bowls as a light main dish. It pairs well with simple steamed rice, stir-fried vegetables, or light dumplings. For extra freshness, you can top it with additional chopped chives or spring onion and a few drops of fresh chili oil for those who like it spicy.
Watch out for
- Don’t let the soup come to a hard boil after adding the starch, or it will turn pasty and heavy.
- If you pour in the egg too quickly or into vigorously boiling soup, you’ll get rubbery clumps instead of thin strands.
- If you add the vinegar much later than the starch, it can thin the soup out and change its texture.
- Be cautious with freshly ground pepper – it’s easier to add more heat than to take it away.
Substitutions
- Swap chicken stock for vegetable stock to make a vegetarian version.
- You can replace plain tofu with smoked tofu if you’d like a deeper, smoky flavor.
- Substitute rice vinegar with a mild apple cider vinegar, adding it gradually and tasting as you go.
- Replace chili paste with chili oil or chili flakes, adjusting the heat with the amount you use.
Ingredients
- chicken or vegetable stock can be made from a cube, but homemade is best - 1 l
- firm natural tofu firm, for cutting into cubes - 200 g
- button mushrooms or other mild mushrooms e.g. oyster mushrooms - 150 g
- carrot - 1 piece
- Chinese cabbage or white cabbage, finely chopped - 150 g
- egg - 1 piece
- rice vinegar can be replaced with light white wine vinegar - 3 tablespoons
- soy sauce light soy sauce is best - 3 tablespoons
- sesame oil for aroma, can be omitted - 1 teaspoon
- potato or corn starch for thickening - 2 tablespoons
- garlic - 2 cloves
- fresh ginger or 0.5 teaspoon dried - 2 cm
- ground pepper black or white - 0.5 teaspoons
- chili paste or chili flakes amount to taste - 0.5 teaspoons
- chives chopped, for serving - 2 tablespoons
Preparation
- Cut the tofu into cubes of about 1 cm. Slice the mushrooms into thin slices, the carrot into thin matchsticks or half-slices, and the Chinese cabbage into thin strips so it softens quickly but still keeps a light crunch after cooking.
- Finely chop the garlic, peel the ginger and grate it on a fine grater. In a small bowl, beat the egg with a fork until the mixture is uniform, with no streaks of white. Set everything aside separately so you can add it at the right moment.
- Heat the stock in a pot until small bubbles appear around the edges, but without a vigorous boil. Add the carrot and mushrooms and cook for 5–7 minutes over medium heat, until the carrot softens but still has a slight bite and the mushrooms darken and soften.
- Add the Chinese cabbage, tofu, garlic, and ginger. Stir gently so you don’t break up the tofu. Cook for 3–4 minutes, until the cabbage has clearly softened and turned slightly opaque and you can strongly smell the garlic and ginger from the pot.
- In a bowl, mix the rice vinegar, soy sauce, pepper, and chili paste or chili flakes. Pour the mixture into the soup, stir, and taste – the flavor should be distinctly sour and spicy but not burning hot; if needed, add 1 teaspoon more vinegar or soy sauce at a time.
- Mix the starch thoroughly with 4 tablespoons of very cold water until there are no lumps. The soup should be gently simmering; pour the mixture in a thin stream while stirring constantly. Cook for 1–2 minutes, until the liquid clearly thickens and lightly coats the spoon but is still pourable.
- Reduce the heat so the soup is only gently bubbling. Pour the beaten egg in a very thin stream just above the surface while stirring the soup in one direction. After a few seconds you’ll see thin, pale ribbons of egg instead of large clumps.
- Finally, add the sesame oil, give it a brief stir, and turn off the heat right away – the surface should have a slight sheen and a clear sesame aroma over the pot. Serve very hot, sprinkled with chives; for a spicier version, add extra chili directly in the bowl.
Storage

I like this version of hot and sour soup because it’s easy to make at home with everyday ingredients, and you can freely adjust the flavor profile. On colder days I add more ginger and chili for extra warmth, and in the summer I keep it milder and lighter on the vinegar. It’s one of those soups that taste even better after a short rest, when all the flavors have had time to meld.
