Vegetarian hot and sour soup – cold, comforting & easy to make

December 29, 2025

Vegetarian hot and sour soup is a warming Indo-Chinese bowl with a gentle chilli kick, savoury soy, tender vegetables and a bright vinegar finish. This version is easy to make on a weeknight and tastes best when the vegetables keep a little bite.

Ingredients

  • 1 tablespoon neutral oil
  • 1 teaspoon grated ginger and 2 cloves garlic, finely chopped
  • 1 small onion, sliced
  • 1 cup shredded cabbage, 1/2 cup carrot and 1/2 cup mushrooms
  • 100 g firm tofu, cubed
  • 4 cups vegetable stock
  • 1 tablespoon soy sauce
  • 1–2 teaspoons rice vinegar and chilli sauce, to taste
  • 1 tablespoon cornflour mixed with 2 tablespoons water
  • Spring onion, black pepper and salt to finish

How to make vegetarian hot and sour soup

  1. Warm the oil in a saucepan. Add ginger, garlic and onion and cook for 2 minutes until fragrant.
  2. Add cabbage, carrot, mushrooms and tofu. Stir-fry for 2–3 minutes so the vegetables stay crisp.
  3. Pour in the stock, soy sauce and black pepper. Simmer for 8–10 minutes.
  4. Stir in the vinegar and chilli sauce. Taste and adjust the salt, sourness and heat.
  5. Stir the cornflour slurry again and pour it in slowly while stirring. Simmer for 1–2 minutes until lightly glossy.
  6. Serve hot with spring onion on top.

Helpful tips

  • Add the vinegar near the end so its fresh flavour remains noticeable.
  • Use vegetable stock rather than water for a fuller soup.
  • For a gluten-free bowl, choose tamari and check the chilli sauce label.
  • Leftovers keep refrigerated for up to 2 days. Reheat gently and loosen with a splash of stock.

Questions people ask

Can I make it without tofu?

Yes. Add extra mushrooms, baby corn or finely sliced beans for more texture.

How do I make it less spicy?

Use a small amount of chilli sauce and add more only after tasting.

Serving suggestion

Serve this soup as a light starter or with steamed rice and vegetable spring rolls for a complete meal. The balance to aim for is savoury first, then sour, with heat that builds gently.
