The best slurp you’ll ever have
If there’s one noodle soup I order from Vietnamese restaurants without fail, it’s a hearty bowl of Banh Canh Cua. When you combine a thick sticky broth with chewy soft noodles, that lip smacking slurp is EVERYTHING.
But there’s one key element that sets our homemade recipe apart from all the ones found in commercial kitchens - we top it with ALL the classic favorites.
This is a loaded bowl of goodness you’re getting yourself into!
Not only do you get to enjoy juicy crab meat hot out of the shell, its delicate sweetness infuses into the broth for an incredible seafood flavor that nothing can replace.
Pair that with an aromatic kick from golden fried prawn puffs, crispy onions and fresh Vietnamese herbs to make it the meal of your dreams.
Do you see the gloriously glossy noodles wrapped around my chopsticks? You can be sure that every drop of soup flavor is absorbing into them, making each strand taste like pure magic.
Why this recipe works
- Chargrilling dried squid adds a deep umami flavor, making the stock beautifully complex.
- Using whole crab naturally sweetens the broth without the need for extra sugar.
- Fried and seasoned prawn paste is added to the pot to infuse aromatics into the soup.
What you’ll need
Broth ingredients
About the seafood
You can find frozen crab meat in seafood markets in the freezers. They’re generally a better quality than the ones sold in supermarkets.
As for the dehydrated squid and scallops, they’re sold in bags in Asian grocery stores.
The toppings
About the meat
We use pork hoc for our recipe, but you can use any cut you prefer. This recipe also uses mud crab, although getting just the claw might be easier because it involves less prep.
For the prawn balls
About the prawns
You may find many types of fresh prawns at your local seafood market. Keep in mind that some are saltier than others, so season accordingly.
Otherwise our Banh Canh Cua recipe can be serve with Chao Tom (Sugar Cane Shrimp).
The noodles
About the tapioca noodles
We buy the cooked banh canh from Asian supermarkets. They’re delivered fresh daily and can be found in the cooked noodles section.
The garnish
About the herbs
Coriander and spring onion can be purchased in bundles from Asian grocery stores and washed then chopped finely before serving.
How to make this recipe
The Broth
Add the pork hoc to the stock and cook it on a low-medium heat.
Bring the stock to a gentle simmer, then grill the dried squid and put them into the broth.
Cut up the jicama and daikon into large chunks.
Turn up the heat to high and add the jicama, daikon and dehydrated scallops into the soup.
After 40 minutes of cooking or when when soft, take the hoc pieces out and set aside.
Note: If you’re using boneless pork, they can be sliced thinly to be used as a topping.
Pour 1 tbsp oil into a small pan and turn the heat to low. Add the annatto seeds in and cook for 1 minute or until its color begins to change.
Note: You’re looking for the oil to turn red, which will color the Banh Canh Cua broth.
Use a sieve to strain the annatto-infused oil into the broth, then season with salt, rock sugar, fish sauce and chicken bouillon powder.
The Prawn Balls and Crab
Heat up a small pan on medium heat and brown the garlic, red shallots and spring onions with 1 tbsp oil. Set it aside to cool.
Combine the fried aromatics with salt, sugar, chicken bouillon powder, pepper, fish sauce and the prawns in a food processor, then process the ingredients into a paste.
Heat up the oil in a pan on medium-high heat. Shape the paste into balls 2cm (0.8″) wide using spoons or hands and fry them for 5 minutes on each side or until golden and cooked.
Bring the pot to a gentle boil and add the prawn balls into the broth.
Add the frozen crab meat in.
Cut up the crab and place them in the soup to cook for 15 minutes or until the flesh is cooked, then remove and set aside until eating time.
To thicken the soup, mix the starch slurry in a bowl until it forms a runny liquid. Slowly pour it into the broth on a low heat while stirring the pot consistently.
The Noodles and Garnish
Bring another pot of water to a boil and add the banh canh in. These noodles are already cooked, so they will only need 3-5 minutes before they can be strained and set to drip dry.
To assemble the dish, line the bottom of your bowl with tapioca noodles then top it with the pork hoc, fried prawn balls, crab and blood jelly. Pour hot soup over the ingredients and garnish with herbs and a squeeze of lime juice!
FAQs
Tips for the best results
- Use fresh crab. Not only will this naturally sweeten the broth, you’ll also get a rich crab flavor that can’t be achieved using frozen ones.
- Slap the prawn paste against a hard surface. For a springier bite, take the prawn paste in your hand and throw it against the inside of the bowl or a chopping board a few times to give it a springy texture when cooked.
- Chargrill the vegetables. Keep the skin on and lightly char them until they blacken, then peel off the skin before adding to the broth. This technique gives the soup an added dimension.
