Cao Lau is the signature noodle bowl of Hoi An in central Vietnam, prized for its thick, chewy rice noodles tossed with slices of five-spice pork, crisp pork crackling, fresh herbs, and just a splash of rich pork broth. The dish balances savory-sweet pork, bright herbs, and a uniquely firm noodle texture that sets it apart from pho or bun. This home version stays true to the Hoi An street-stall tradition without requiring the legendary Ba Le well water.

Ingredients
For the five-spice pork
- 500 g (1.1 lb) pork shoulder, sliced 5 mm thick
- 3 tablespoons soy sauce
- 2 tablespoons hoisin sauce
- 1 tablespoon honey
- 1 teaspoon Chinese five-spice powder
- 3 cloves garlic, minced
- 1 tablespoon neutral oil
For the pork broth
- 1.2 kg (2.6 lb) pork bones, blanched
- 1 large white onion, charred
- 1 piece ginger (40 g), sliced and charred
- 2 tablespoons fish sauce
- 1 tablespoon sugar
- 2 star anise
- 1 cinnamon stick
- 2.5 liters (10 cups) water
For the noodles and crispy pork
- 600 g fresh thick rice noodles (cao lau style)
- 200 g pork skin, scrubbed clean
- 1 liter vegetable oil for frying
- 1 teaspoon salt
For assembly and toppings
- 150 g fresh bean sprouts, blanched 10 seconds
- 1 small head green lettuce, torn
- 1 cup Vietnamese mint leaves
- 1 cup Thai basil leaves
- 1/2 cup cilantro
- 3 scallions, thinly sliced
- 1 red chili, sliced
- 1 lime, cut into wedges
- 2 tablespoons crispy fried shallots
- 2 tablespoons chili-garlic sauce (tuong ot)
Directions
- In a bowl, combine pork shoulder slices with soy sauce, hoisin, honey, five-spice, garlic, and oil. Massage well, cover, and marinate for at least 30 minutes (overnight for deeper flavor).
- While the pork marinates, prepare the broth: in a large pot, combine blanched pork bones, charred onion and ginger, star anise, cinnamon, and water. Bring to a boil, then simmer uncovered for 45 minutes. Season with fish sauce and sugar, then strain and keep hot.
- Cook the marinated pork in a hot skillet or grill pan over medium-high heat for 2-3 minutes per side until caramelized and lightly charred. Rest for 5 minutes, then slice into bite-sized strips.
- For the crispy pork, simmer pork skin in salted water for 40 minutes until tender. Drain, pat dry thoroughly, then fry in 170 degrees C oil for 4-5 minutes until puffed and golden. Drain on paper towels and season with a pinch of salt.
- Blanch the rice noodles in boiling water for 1-2 minutes until just tender but still chewy, then drain and rinse briefly under warm water. Divide the noodles among 4 large bowls.
- Ladle about 120 ml of the hot pork broth into each bowl, just enough to barely cover the noodles. Top with sliced pork, a generous handful of crispy pork pieces, bean sprouts, lettuce, and herbs.
- Finish each bowl with scallions, sliced chili, fried shallots, a wedge of lime, and a spoonful of chili-garlic sauce on the side. Serve immediately while the noodles are still warm and chewy.
Cook’s Notes
- True Cao Lau noodles are thick rice noodles with a firm bite, unlike pho or bun noodles; if unavailable, look for fresh wide rice noodles or thick Japanese-style rice udon as the closest substitute.
- The broth should only lightly coat the noodles, not pool like pho. Authentic Hoi An cooks use minimal liquid to keep the noodle texture distinct.
- Marinate the pork overnight for the best caramelization and depth of five-spice flavor when grilled or pan-seared.
- For extra contrast, reserve a small bowl of extra hot broth on the side so diners can add more as desired without diluting the noodle flavor.
- Char the onion and ginger directly over a gas flame or in a dry skillet until blackened before adding to the broth – this adds essential smoky depth to the stock.
