Cao Lầu: A Culinary Journey to Hoi An – Authentic Vietnamese Noodle Bowl Recipe

Cao lầu is a quintessential Vietnamese noodle dish hailing from the ancient trading port of Hoi An. Unlike pho or bun cha, cao lầu boasts a unique textural experience thanks to its distinctive noodles. These aren’t your average rice noodles; they’re thick, chewy, and slightly al dente, crafted using a special process that reportedly involves water from the ancient Ba Le well and ash from specific trees found only in the surrounding Cham Islands. While replicating the exact authenticity at home is challenging, this recipe provides a delicious and accessible version that captures the essence of this Hoi An specialty.

What Makes Cao Lầu Special?

Beyond the noodles, cao lầu is a symphony of flavors and textures. Imagine succulent slices of char siu-inspired pork, crispy croutons of fried cao lầu noodles, fresh greens, aromatic herbs, and a flavorful broth that ties it all together. Each element contributes to the overall experience, making it a truly unforgettable dish.

Ingredients You’ll Need

Let’s break down the ingredients for each component of this delectable dish:

For the Cao Lầu Noodles:

• 1 pound thick fresh egg noodles (udon noodles are a good substitute): These provide the chewy texture similar to traditional cao lầu noodles. Fresh is best, but dried udon noodles can be used if rehydrated properly.
• 1 tablespoon vegetable oil: To prevent sticking during cooking.

For the Char Siu-Inspired Pork:

• 1.5 pounds pork shoulder (Boston butt), cut into 1-inch thick slices: Pork shoulder offers a good balance of fat and meat, resulting in a tender and flavorful dish.
• 2 tablespoons hoisin sauce: Adds a sweet and savory umami flavor.
• 1 tablespoon soy sauce: Provides saltiness and depth of flavor.
• 1 tablespoon honey: Contributes to the glaze and caramelization.
• 1 tablespoon Chinese five-spice powder: A blend of spices that adds warmth and complexity.
• 1 tablespoon minced garlic: For aromatic flavor.
• 1 teaspoon grated ginger: Adds a spicy and zesty note.
• 1/2 teaspoon red food coloring (optional): For the characteristic red hue of char siu. This is purely for aesthetics and can be omitted.
• 1 tablespoon vegetable oil: For searing the pork.

For the Crispy Cao Lầu Noodle Croutons:

• 4 ounces dried cao lầu noodles (or thick egg noodles), broken into small pieces: These are deep-fried to create a crunchy topping. If you can’t find dried cao lầu noodles, thick dried egg noodles will work.
• Vegetable oil, for deep frying: Enough to submerge the noodles.

For the Broth:

• 8 cups chicken broth: Forms the base of the broth. You can use homemade or store-bought.
• 2 tablespoons soy sauce: Adds saltiness and umami.
• 1 tablespoon fish sauce: For a savory and pungent flavor. Use sparingly, as it can be quite strong.
• 1 tablespoon brown sugar: Balances the saltiness and adds a touch of sweetness.
• 1 star anise: Contributes a warm, licorice-like flavor.
• 1 cinnamon stick: Adds a sweet and woody aroma.
• 1 (2-inch) piece of ginger, bruised: Releases its aromatic oils into the broth.

For the Garnish:

• 1 cup bean sprouts: Adds a refreshing crunch.
• 1 cup lettuce, shredded: Provides a base of fresh greens. Romaine or butter lettuce works well.
• 1/2 cup fresh mint leaves: Adds a cool and refreshing flavor.
• 1/2 cup fresh cilantro leaves: For a bright and citrusy aroma.
• 1/4 cup chopped peanuts: Adds a nutty flavor and crunchy texture.
• Lime wedges, for serving: To add a squeeze of acidity.
• Chili sauce (optional), for serving: For those who like a spicy kick.

Step-by-Step Instructions

Now, let’s get cooking! Follow these detailed instructions to create your own delicious bowl of cao lầu:

Step 1: Prepare the Pork

1. In a large bowl, combine the hoisin sauce, soy sauce, honey, Chinese five-spice powder, minced garlic, grated ginger, and red food coloring (if using).
2. Add the pork slices to the marinade, ensuring they are well coated. Cover the bowl and refrigerate for at least 2 hours, or preferably overnight, to allow the flavors to meld.
3. Heat the vegetable oil in a large skillet or wok over medium-high heat.
4. Remove the pork slices from the marinade, reserving the marinade. Sear the pork on both sides until browned, about 3-4 minutes per side.
5. Pour the reserved marinade into the skillet and bring to a simmer. Reduce the heat to low, cover the skillet, and simmer for about 1-1.5 hours, or until the pork is tender and easily shredded with a fork. Turn the pork occasionally to ensure even cooking.
6. Remove the pork from the skillet and let it cool slightly. Shred the pork using two forks.
7. Set the shredded pork aside.

Step 2: Prepare the Crispy Cao Lầu Noodle Croutons

1. Heat vegetable oil in a deep fryer or large pot to 350°F (175°C).
2. Carefully add the broken cao lầu noodles (or egg noodles) to the hot oil in small batches.
3. Fry for about 1-2 minutes, or until golden brown and crispy. Use a slotted spoon to remove the croutons from the oil and place them on a paper towel-lined plate to drain excess oil.
4. Set the crispy noodle croutons aside.

Step 3: Prepare the Broth

1. In a large pot or Dutch oven, combine the chicken broth, soy sauce, fish sauce, brown sugar, star anise, cinnamon stick, and bruised ginger.
2. Bring the broth to a boil over medium-high heat.
3. Reduce the heat to low and simmer for at least 30 minutes, or up to 1 hour, to allow the flavors to meld. The longer it simmers, the more flavorful the broth will be.
4. Remove the star anise, cinnamon stick, and ginger from the broth before serving.
5. Keep the broth warm over low heat.

Step 4: Cook the Noodles

1. Bring a large pot of water to a boil.
2. Add the fresh egg noodles (or udon noodles) to the boiling water and cook according to package directions, usually about 2-3 minutes, or until tender.
3. Drain the noodles well and toss them with 1 tablespoon of vegetable oil to prevent sticking.

Step 5: Assemble the Cao Lầu

1. Divide the cooked noodles among bowls.
2. Top the noodles with shredded lettuce, bean sprouts, and shredded char siu-inspired pork.
3. Spoon a generous amount of warm broth over the noodles and pork.
4. Garnish with crispy cao lầu noodle croutons, fresh mint leaves, cilantro leaves, and chopped peanuts.
5. Serve immediately with lime wedges and chili sauce (optional) on the side.

Tips and Variations

• Noodle Substitutes: If you can’t find fresh egg noodles or udon noodles, thick dried egg noodles can be used. Rehydrate them according to package directions before cooking.
• Pork Variations: You can use other cuts of pork, such as pork tenderloin or pork loin, but adjust the cooking time accordingly. You can also use grilled chicken or shrimp as a substitute for pork.
• Vegetarian Option: Substitute tofu or tempeh for the pork. Marinate the tofu or tempeh in the same marinade as the pork and pan-fry or bake until golden brown. Use vegetable broth instead of chicken broth.
• Broth Enhancements: For a richer broth, add a few dried shiitake mushrooms or a piece of dried seaweed (kombu) to the broth while simmering.
• Spice Level: Adjust the amount of chili sauce to your liking. You can also add a pinch of red pepper flakes to the broth for extra heat.
• Make Ahead: The char siu-inspired pork and broth can be made ahead of time and stored in the refrigerator for up to 3 days. The crispy cao lầu noodle croutons are best served fresh, but can be stored in an airtight container at room temperature for up to 2 days.

Serving Suggestions

Cao lầu is best served immediately after assembly. The combination of warm noodles, flavorful broth, tender pork, and crispy croutons is a true delight. Serve with lime wedges and chili sauce on the side, allowing guests to customize their bowl to their liking.
