Bún riêu cua: Vietnam's tomato and crab noodle soup

2 min readBy the Eat Green Vietnam team

Red, tangy and full of texture, bún riêu is the bowl locals choose when they want something lighter than phở.

Quick answer

Bún riêu cua is a tangy noodle soup made with freshwater paddy crabs: the crab is pounded and cooked into soft clouds (riêu) floating in a tomato broth with fried tofu and rice noodles. It usually costs 30,000–50,000 VND. Order with “Cho tôi một bát bún riêu”.
