Fiery spicy lamb stir-fry with cumin and chilies is a bold, protein-rich dish. A carnivore-friendly, family dinner with fresh, aromatic spices.
Toss sliced lamb shoulder with 1 tablespoon soy sauce, Shaoxing wine, and black pepper; let it marinate for at least 15 minutes.
Heat a large wok over high heat until just smoking, then add half the vegetable oil. Stir-fry lamb quickly in two batches for 1–2 minutes each until browned but still juicy. Remove lamb and set aside.
Reduce heat to medium-high, add remaining oil to the wok, then stir-fry dried chilies, garlic, and ginger for 30 seconds until fragrant but not burning.
Add sliced onion and both bell peppers, cooking for 2–3 minutes while stirring. Vegetables should be crisp-tender.
Return lamb and any juices to the wok. Sprinkle in ground cumin and sugar, then toss everything together briskly for about 2 minutes so flavors absorb. Taste and adjust salt if necessary.
Finish with chopped cilantro and serve hot, ideally immediately so meat stays tender and veggies retain color and crunch.
