Northern Vietnamese Crab and Tomato Noodle Soup / Canh Bún

For most of its life, Canh Bún has lived in the shadows of its more famous counterpart, Bún riêu, and I think it’s finally time to give it the flowers that it justly deserves.

What is Canh Bun?

Canh Bun is a Northern Vietnamese noodle soup with a vibrant red broth. The broth is typically made with pork bones, dried shrimp, and fermented shrimp paste. Toppings can include thick rice noodles, crab meatballs (rieu), tomatoes, and morning glory.

Canh Bun or Bun Rieu?

The two soups are very similar, as they share the same broth and crab meatballs. The main differences between them are the noodles, veggies, and herbs.

Canh Bún uses a thick rice noodle, similar to what you would find in bún bò Huế, while bún riêu uses the more common rice vermicelli noodle, similar to what you would find in bún thịt nướng.

For the veggies, Canh Bún has blanched rau muống (water spinach) and garlic chives, whereas bún riêu has banana blossom, cabbage, lettuce, cilantro, and green onions. Ultimately, I believe both are equally delicious and deserving of their own spotlight. It just comes down to your preferences, but you can’t lose either way.

Ingredients

  • 6 quarts water

  • 2 lbs pork spareribs

  • ½ cup dehydrated shrimp

  • 1 yellow onion

  • 2 cubes bún riêu/canh bún seasoning

  • 7 oz crab paste with soya oil

  • 3 large roma tomatoes

  • 4 tbsp fish sauce

  • 1 inch nub of rock sugar

  • 2 tbsp msg

  • 1 tbsp mắm ruốc (fermented shrimp paste)

  • Salt to taste

  • Crab Meatball (Rieu):
  • 1 lb lean ground pork

  • 16 oz jumbo lump crab

  • 7 oz crab paste with soya oil

  • 3 eggs

  • 1 tbsp fish sauce

  • Salt and pepper to taste

  • Noodles:
  • 32 oz thick rice noodles

  • Toppings:
  • Chả chiên (fried vietnamese ham)

  • Tofu puffs

  • Rau muống (water spinach)

  • Garnishes:
  • Garlic chives

  • Limes

  • Black pepper

Directions

  • Parboil pork spareribs, then rinse and clean pork under cold water
  • To a clean stockpot add six quarts of water and bring up to a boil, add cleaned pork, a whole yellow onion, and half a cup of rehydrated dried shrimps
  • Add 2 cubes of bun rieu seasoning, and just the oil from a jar of crab paste with soya oil
  • Bring up to a boil, skim off any impurities and let that simmer for 2 hours
  • Season broth with rock sugar, msg, fish sauce, and salt to taste
  • Make crab meatballs by combining, group pork, jumbo lump crab, the remaining crab paste, and eggs. Season with fish sauce and salt and pepper. Form loose balls with a spoon, and drop them into the stock pot
  • Add roma tomatoes, tofu puffs and shrimp paste to the broth
  • Cook thick rice noodles in heavily salted water – the brand I use has wrong cooking instructions – as it says you only need to cook for 7-8 minutes. I’ve found that I’ve needed to cook for 30-35 minutes to get to al dente
  • Cut water spinach into 1-2 inch sections, then in a separate pot blanch water spinach, and shock in cold water to stop the cooking process and keep them green
  • Thinly slice fried Vietnamese ham and cut garlic chives into one inch pieces for garnishes
  • Assemble your bowl by adding noodles, proteins, broth and garnishes
