Canh Bi Xanh Nau Tom is a traditional Vietnamese dish that strikes a beautiful balance between fresh ingredients and bright, intense aromas.

Ingredients (serves 1–2)
- 200g fresh prawns
- 100g green squash blossoms
- 1 litre vegetable or fish stock
- 1 onion, finely chopped
- 2–3 spring onions, sliced into rings
- A bunch of fresh herbs (such as coriander and mint)
- Salt and pepper, to taste
Shopping for the ingredients
When shopping for canh bi xanh nau tom, it is worth putting freshness first. Visit a local Asian market to make sure you find good-quality prawns and crisp squash blossoms. Check that the prawns have a clear colour and no off smells. The green squash blossoms should be vibrant and perky rather than wilted, which guarantees the best flavour and the most appealing look in the finished soup.
Preparing the dish
Preparing canh bi xanh nau tom is quick and straightforward. Begin by peeling the prawns and removing the dark vein if needed. Wash the squash blossoms gently to rinse away any sand or grit. Chop the onion and slice the spring onions so they are ready for the pan. Getting all your ingredients prepped in advance keeps the cooking process smooth and relaxed from start to finish.
Step-by-step instructions
- Bring the stock to the boil in a large pan.
- Add the chopped onion and sauté for a few minutes until soft.
- Add the prawns to the broth and cook for around 3–5 minutes, until pink and cooked through.
- Gently slide in the green squash blossoms and let everything simmer for a further 2 minutes.
- Season with salt and pepper, then stir in the spring onions and fresh herbs.
- Serve the soup hot, garnished with extra herbs to taste.
Gluten-free / lactose-free version
Canh bi xanh nau tom is easy to make gluten-free and lactose-free. Simply swap the regular stock for a gluten-free vegetable stock, and double-check that every other ingredient, especially any seasonings, is also free from gluten. The dish is naturally lactose-free, so there is nothing extra to worry about on that front. With one small substitution, it suits a gluten-intolerant diet perfectly.
Tips for vegans and vegetarians
To make canh bi xanh nau tom suitable for vegans and vegetarians, you can replace the prawns with tofu or another plant-based protein. Swap the fish stock for a robust vegetable stock to keep the savoury depth intact. Adding more vegetables, such as carrots or broccoli, makes the soup even more nourishing. Lean on plenty of fragrant herbs to bring out a rich variety of flavours.
More tips and tricks
To get the very best from your canh bi xanh nau tom, experiment with the cooking time of each ingredient. The natural sweetness of the prawns and the delicate squash blossoms shine when they are not overcooked. Go easy on the seasoning, as the fresh ingredients carry most of the flavour on their own. A squeeze of lime juice just before serving lifts the aromas beautifully.
Adapting the recipe to your taste
Tailor canh bi xanh nau tom to your own palate by changing up the herbs or adjusting the seasoning. If you like a bit of heat, add a few chillies or an extra grind of pepper. For a more substantial version, fold in other seafood such as clams or squid. The flexibility of the recipe gives you plenty of room to get creative, much like the fresh, adaptable rolls in Goi Cuon Tom Thit.
Ingredient substitutions
If you cannot find green squash blossoms, spinach or chard make excellent stand-ins. Fresh peas or courgette would also slot in nicely. In place of the prawns, you could use grilled chicken pieces or a plant-based alternative for a completely different character. Substitutions like these keep the dish tasty and flexible, whatever happens to be in season or in your fridge.
Drink pairing ideas
A bowl of canh bi xanh nau tom pairs beautifully with freshly brewed green tea or a fruity homemade lemonade, both of which complement the soup’s gentle flavours. A light, dry white wine would also be an excellent match. For a non-alcoholic option, sparkling water with fresh lime or mint leaves is hard to beat. These drinks offer a refreshing counterpoint to the dish.
Serving and presentation ideas
The presentation of canh bi xanh nau tom improves no end when you serve it in decorative bowls or deep dishes. Garnish the soup with fresh herbs and a few extra squash blossoms to create a prettier visual impression. A splash of lime juice over the top adds an elegant touch as well as a little extra flavour. Highlight the colours of the ingredients to make the dish look as inviting as possible.
