Hailing from the noodle shops of Gansu Province in northwest China, this iconic bowl features a clear, aromatic beef broth, hand-pulled alkaline noodles, tender sliced beef, and a fragrant topping of cilantro, scallions, and chili oil. The broth is the soul of the dish—slowly simmered with beef bones, warming spices, and daikon for a clean yet deeply savory flavor.

Ingredients

For the beef broth

  • 2 lb beef shank with bone, cut into 2-inch chunks
  • 1 large daikon radish, peeled and cut into 1-inch chunks
  • 1 large yellow onion, halved (skin on)
  • 4-inch piece fresh ginger, smashed
  • 6 garlic cloves, smashed
  • 3 star anise, 2 cinnamon sticks, 1 bay leaf, and 1 tbsp Sichuan peppercorns
  • 2 tbsp Shaoxing wine
  • 10 cups cold water

For the noodles and beef

  • 1 lb fresh alkaline wheat noodles (lamian)
  • 8 oz baby bok choy or baby spinach
  • 1 tbsp kosher salt, plus more to taste
  • Reserved cooked beef shank, thinly sliced against the grain

For the chili oil and seasoning

  • 3 tbsp Chinese chili oil with sediment
  • 2 tbsp light soy sauce
  • 1 tbsp Chinkiang black vinegar
  • 1/2 tsp ground white pepper
  • 4 scallions, thinly sliced
  • 1/2 cup fresh cilantro, chopped
  • 1 cup finely chopped pickled mustard greens (suan cai), optional

Directions

  1. Place the beef shank in a large stockpot, cover with cold water, and bring to a boil. Blanch for 5 minutes, then drain and rinse the beef and pot to remove impurities for a clearer broth.
  2. Return beef to the cleaned pot with daikon, onion, ginger, garlic, star anise, cinnamon, bay leaf, Sichuan peppercorns, Shaoxing wine, and 10 cups cold water. Bring to a boil over high heat, then immediately reduce to a bare simmer, skimming any foam that rises.
  3. Partially cover and simmer gently for 2.5 to 3 hours, until the beef is fork-tender and the broth is rich and clear. Remove the beef, let cool, and slice thinly against the grain; set aside.
  4. Strain the broth through a fine-mesh sieve into a clean pot, season with 1 tablespoon salt and the white pepper, and keep at a rolling boil for service.
  5. Bring a separate large pot of water to a vigorous boil. Add the noodles and cook 3 to 4 minutes until just tender with a slight chew; drain and divide evenly among 4 large bowls.
  6. Blanch the bok choy in the noodle water for 30 seconds, then arrange on top of the noodles along with the sliced beef.
  7. Ladle about 2 cups of the hot broth into each bowl, making sure each portion has a few slices of daikon from the broth.
  8. Top each bowl with scallions, cilantro, pickled mustard greens (if using), a generous spoonful of chili oil with its sediment, and a splash of soy sauce and black vinegar. Serve immediately with extra chili oil on the side.

Cook’s Notes

  • For the clearest, most authentic broth, simmer gently and never let it boil hard—agitation makes it cloudy. Skim the surface every 30 minutes.
  • Make the broth a day ahead and refrigerate overnight; the fat will solidify on top for easy removal, and the flavor deepens considerably.
  • Look for fresh alkaline wheat noodles (lamian) at Chinese or Korean markets. Avoid substituting dried pasta, which lacks the characteristic chewy bite.
  • Always include the chili oil sediment (the red flakes at the bottom of the jar), not just the clear oil—this gives Lanzhou-style broth its signature ruby sheen and aromatic depth.
  • If you want to pull your own noodles, use a high-gluten flour dough rested for 2 hours, then stretch and fold repeatedly on an oiled surface until thin and elastic.
