Bún Riêu Chay (Vegan Crab Noodle Soup)

Bun Rieu Chay

Bún Riêu Chay is a light yet comforting Vietnamese noodle soup with a tomato-infused base, creamy tofu ‘crab’ blend, and served with fresh herbs. A delicious yet underrated Vietnamese dish.

What is Bún Riêu Chay (Vegan Vietnamese Crab Noodle Soup)?

Bún Riêu Chay is a plant-based version of the traditional Vietnamese Crab Noodle Soup – a popular noodle soup from Northern Vietnam. It has a balance of tangy flavors from the tomato and sweetness from the mushrooms. Moreover, this noodle soup is perfect for the fall and winter months, as it’s like a comforting hug in a bowl!

This original dish uses crab blend to make the Riêu, but to make it 100% plant-based, we are using the bean curds achieved by boiling soy milk and adding salt and lime juice. Use a small strainer to strain out the bean curds, add this to a bowl and combine with some seasonings.

Why does this work? – Soy milk, when interacting with something salty (salt) and acidic (lime or lemon juice or rice vinegar), will separate into liquid and bean curds. This is similar to the process of making tofu.

  5. Cut the ends off the Shimeji mushrooms and add to the broth. Add fried tofu. Cook for 10 minutes then serve.
  6. Season the broth with salt and soy sauce to taste.

Prepare the toppings

  1. Cook the rice noodles according to the package instructions. Rinse and drain under cold water.

  3. Serve the noodle soup with fresh herbs and enjoy!

Notes

Use natural, unsweetened soy milk to yield the best result. If the soy milk doesn’t curdle, add more salt or lime juice.
