A takeout favorite made easy at home, Mongolian Beef features crispy seared steak in a sticky soy-garlic sauce, perfect over steamed rice.
1 lb flank steak, thinly sliced against the grain
1/4 cup cornstarch
1/4 cup vegetable oil (for frying)
1/3 cup low-sodium soy sauce
1/4 cup water or beef broth
1/3 cup brown sugar, packed
3 cloves garlic, minced
1 tablespoon fresh ginger, grated
4–5 green onions, cut into 2-inch pieces
Optional: dried red chilies or chili paste (for spice)
Toss sliced beef with cornstarch and let sit for 10–15 minutes.
In a bowl, mix soy sauce, water, brown sugar, garlic, and ginger.
Heat oil in a wok over medium-high. Fry beef in batches until crisp; remove and set aside.
Discard excess oil, leaving 1–2 tsp. Add garlic and ginger, sauté 30 seconds.
Pour in sauce; simmer 2 minutes until slightly thickened.
Return beef to pan; stir to coat. Add green onions and cook 1 minute.
Serve immediately over rice or noodles.
