Mongolian Beef

Updated January 16, 2026

Crispy beef in sweet-savory soy sauce with scallions.

Mongolian beef is American-Chinese; it has no connection to Mongolian cuisine. Flank steak is traditional; skirt steak or sirloin work well.

For extra crispy beef, double-fry: first at 325°F, rest, then 375°F. Serve immediately; the crispy coating softens as it sits.
