This comforting and flavourful noodle soup dish features a sweet and tangy tomato broth, vegan ‘crab cakes’, herbs and tofu puffs.

Vietnamese Crab Noodle Soup features a rich, flavourful and tangy broth made with crab, often served with thick rice vermicelli, and topped with crab meat, herbs, and fried shallots. The soup is a popular dish in central and southern Vietnam, especially in coastal areas where crab is abundant!

In this version, we’ll be making a plant based rendition of this dish by making vegan ‘crab’ cakes using hearts of palm and extra firm tofu. Hearts of palm is one of my favourite seafood substitutes due to its versatile flavour and flaky fish-like texture. It comes together nicely for these vegan crab cakes that we will be serving in this dish.

This noodle soup is the definition of comfort food and the broth itself only takes about 15 minutes to make. If you have ‘crab’ cakes prepared and frozen, you can whip up this meal in under 25 minutes – it’s always the prep that takes more time but your past self will definitely thank you future self with this one.
