1. Bun Rieu Recipe (Yield: 8 Bowls)
Ingredients
- 2½ pounds pork shoulder
- 1 yellow onion
- 10 dried shrimp
- 1 teaspoon salt
- 3 stalks green onions
- 1 teaspoon chili powder
- 6 Roma tomatoes, halved
- 1 can (14.5 ounces) chicken broth
- 2 tablespoons fish sauce
- 7 ounces crab paste (about 1 jar)
- 3 eggs
- 1 lime
- 2 packages rice vermicelli noodles
Instructions
Place the dried shrimp into a small bowl and cover them with warm water. Let them soak for about 20 minutes until softened, then drain well.
Bring a large stockpot of water to a boil. Add the pork shoulder and boil for about 5 minutes. Drain the pork, rinse it under cold water, and wash the pot. This step removes impurities and creates a cleaner broth.
Return the cleaned pork shoulder to the pot. Add about 10 cups of fresh water, the whole yellow onion, and the salt.
Bring everything to a gentle boil over medium-high heat. Skim off any foam that rises to the surface. Reduce the heat to low and simmer for about 1½ to 2 hours, or until the pork becomes tender.
Remove the pork shoulder from the broth and allow it to cool slightly. Slice it into thin pieces or shred it into bite-sized pieces. Set aside.
Discard the cooked onion.
While the broth simmers, finely chop the soaked dried shrimp.
In a mixing bowl, combine the chopped dried shrimp, crab paste, eggs, chopped green onions, and chili powder. Stir until everything is evenly blended.
Bring the broth back to a gentle simmer. Slowly spoon the crab mixture into the broth a little at a time. Avoid stirring immediately. As the mixture cooks, it will naturally float to the surface and form delicate crab clusters.
Cook the crab mixture for about 10 to 15 minutes until fully set.
Meanwhile, heat a skillet over medium heat. Add a small amount of oil if desired and cook the Roma tomatoes for about 5 minutes until they soften slightly.
Transfer the cooked tomatoes into the soup. Next, pour in the chicken broth and stir gently. Then season the broth with fish sauce and adjust the salt to taste.
Cook the rice vermicelli noodles according to the package directions. Drain and rinse briefly with warm water to remove excess starch.
Divide the cooked noodles evenly among serving bowls. Top each bowl with sliced pork.
Ladle the hot broth, tomatoes, and crab mixture over the noodles.
Serve immediately with fresh lime wedges on the side. Many people also enjoy Bun Rieu with fresh herbs, shredded lettuce, bean sprouts, and chili paste for additional flavor and texture.
2. Tips for Perfect Homemade Bun Rieu
Use pork shoulder with a little marbling for a richer broth and more tender meat.
Soak the dried shrimp until fully softened before chopping. This helps them blend smoothly into the crab mixture and enhances the seafood flavor.
Allow the broth to simmer gently after adding the crab mixture. Vigorous boiling can break apart the delicate crab clusters.
Cook the tomatoes separately before adding them to the soup. This develops a sweeter flavor and helps preserve their shape.
Taste the broth after adding the fish sauce and chicken broth. Small adjustments at the end can greatly improve the balance of flavors.
Cook the vermicelli noodles separately instead of directly in the broth. This keeps the broth clear and prevents the noodles from absorbing too much liquid.
Serve the soup immediately after assembling each bowl for the freshest texture and best presentation.
Offer fresh herbs, lime wedges, bean sprouts, and chili paste at the table so everyone can customize their bowl.
3. Frequently Asked Questions
Can I make Bun Rieu ahead of time?
Yes. The broth and pork can be prepared one or two days in advance and refrigerated. Cook the noodles fresh when you’re ready to serve.
Can I freeze the broth?
Yes. Allow the broth to cool completely before freezing it in airtight containers for up to three months. Freeze the noodles separately for the best texture.
What type of noodles should I use?
Traditional Bun Rieu uses medium-sized rice vermicelli noodles labeled “bún.” Their soft texture pairs perfectly with the light broth.
Can I add more seafood?
Absolutely. Many homemade versions include shrimp, fried tofu, fish balls, or crab meat for additional flavor and variety.
Why are my crab clusters falling apart?
This usually happens if the broth boils too vigorously or if the soup is stirred immediately after adding the crab mixture. Keep the broth at a gentle simmer until the clusters have fully set.
