This spicy cumin lamb noodle dish transforms weeknight dinner into something extraordinary with minimal effort. The aromatic blend of toasted cumin and Sichuan peppercorns creates an authentic flavor profile that rivals your favorite restaurant version, all in just 30 minutes from start to finish.
I first created this recipe after returning from a trip to Xi'an, China, where hand-pulled noodles with cumin-spiced lamb left such an impression that I had to recreate it at home. After several attempts, this streamlined version captures those bold flavors while fitting into my busy schedule.
Ingredients
- Wide rice noodles: Forming the perfect base for soaking up the flavorful sauce
- American lamb shoulder: Providing a tender texture when thinly sliced
- Cumin seeds and Sichuan peppercorns: Creating authentic depth when freshly toasted
- Ginger and garlic: Providing aromatic foundation for the dish
- Green onions and yellow onions: Adding sweetness and texture
- Soy sauce: Balancing the spices with umami richness
- Chili oil: Delivering customizable heat level
- Sesame oil: Offering nutty aroma that rounds out the flavors
- Rice wine vinegar: Bringing brightness to cut through the richness
- Cilantro: Adding fresh herbal notes that complement the warm spices
Step-by-Step Instructions
- Toast the Spices:
- Heat a dry skillet over medium-low heat until warm. Add cumin seeds and Sichuan peppercorns, stirring constantly to prevent burning. When they become fragrant after about 2-3 minutes, remove from heat immediately. Allow to cool slightly before grinding coarsely in a spice grinder or mortar and pestle. This freshly toasted spice blend provides significantly more flavor than pre-ground spices.
- Cook the Noodles:
- Bring a large pot of water to a rolling boil. Add rice noodles and cook according to package directions until just tender. Before draining, reserve 1 cup of the starchy cooking water to help create a silky sauce later. Drain noodles and rinse briefly with cool water to prevent sticking if not using immediately.
- Prepare the Lamb Mixture:
- Heat vegetable oil in a large wok or skillet over medium heat until shimmering. Add minced ginger and garlic, stirring constantly to prevent burning while they release their aromatics for about 1 minute. Increase heat to high and add thinly sliced lamb shoulder. Spread it evenly across the pan and allow it to brown for 1-2 minutes before stirring. Once lamb is just browned, add your freshly ground spice mixture, stirring to coat evenly.
- Build the Flavor Base:
- Add chopped green onions, sliced yellow onion, and finely chopped serrano pepper if using. Stir-fry for about 1 minute until vegetables begin to soften. Pour in soy sauce, chili oil, sesame oil, rice wine vinegar, and sugar. Allow sauce to simmer vigorously for about 5 minutes, reducing slightly. If mixture becomes too dry, add a splash of water to maintain a saucy consistency.
- Combine and Finish:
- Add cooked noodles directly to the skillet with the lamb mixture. Using tongs, gently toss to coat every strand with the flavorful sauce. If noodles seem dry, gradually add reserved pasta cooking water to create a silkier texture. Taste and adjust seasoning with salt if needed. The noodles should be glossy and well-coated with the aromatic sauce.

My absolute favorite component of this dish is the contrasting texture between the tender lamb and the chewy noodles. The first time I made this for my Chinese friend, she closed her eyes in appreciation and said it reminded her of home. That moment solidified this recipe as one of my most treasured culinary achievements.
Adjusting The Heat Level
This recipe includes serrano pepper and chili oil that can be modified to suit your preference. For a milder version, remove the seeds from the serrano or omit it entirely. If you enjoy spice, add an extra drizzle of chili oil before serving or include additional fresh chilies in the cooking process. The beauty of making this at home is controlling exactly how spicy you prefer it.
Noodle Alternatives
While wide rice noodles provide an authentic experience, this versatile recipe works beautifully with other options. Try hand-pulled or knife-cut wheat noodles for a more traditional Xi'an style. For a lower-carb alternative, zucchini noodles or shirataki noodles can be substituted, though you'll want to reduce the cooking time significantly. Even standard spaghetti or udon can work in a pinch when paired with this flavorful lamb mixture.
Make-Ahead Tips
This dish comes together quickly, but you can prep components ahead of time for even faster assembly. Slice the lamb and vegetables up to a day in advance and store them separately in airtight containers in the refrigerator. The spice mixture can be toasted and ground several days ahead, though for maximum flavor, store in an airtight container away from light and heat. The complete dish reheats beautifully, making it ideal for meal prep or leftovers.

This dish proves that restaurant-quality meals can be achieved in the comfort of your home without compromise or complexity.
Frequently Asked Questions
- → Can I substitute the lamb with another protein?
Yes, you can substitute the lamb with beef, particularly flank or sirloin steak sliced thinly against the grain. For a lighter option, chicken thighs work well too. Just adjust cooking times accordingly as lamb typically needs less time than beef but more than chicken.
- → How spicy is this dish and can I adjust the heat level?
The dish has a moderate heat level from the Sichuan peppercorns, serrano pepper, and chili oil. To reduce spiciness, omit the serrano pepper and use less chili oil. For more heat, add more chili oil when serving or include additional fresh chilies during cooking.
- → Can I use pre-ground cumin instead of toasting whole seeds?
While toasting whole cumin seeds provides the best aromatic flavor, you can substitute with 2 tablespoons of pre-ground cumin in a pinch. Toast the ground cumin briefly in a dry pan to enhance its flavor before adding to the dish.
- → What can I use instead of rice noodles?
This versatile dish works well with many noodle varieties. Try wheat noodles like lo mein or ramen, egg noodles, or even udon for a different texture. For a lower-carb option, substitute with zucchini noodles or shirataki noodles.
- → How do I properly slice lamb for this dish?
For tender results, slice the lamb shoulder very thinly (about 1/8 inch) against the grain. Partially freezing the meat for 15-20 minutes before slicing makes this task easier. Ensure your knife is sharp and cut at a slight angle for optimal texture.
- → What sides pair well with these noodles?
These noodles work beautifully with simple vegetable sides like stir-fried bok choy, steamed broccoli, or a refreshing cucumber salad with rice vinegar dressing. For a complete meal, consider adding spring rolls or dumplings as appetizers.
