Crispy slices of beef tossed in a rich soy-garlic sauce, Mongolian Beef is a quick and satisfying stir-fry that brings takeout flavor straight to your kitchen.
1 lb flank steak, thinly sliced against the grain
1/4 cup cornstarch
3 tbsp neutral oil (vegetable or canola)
3 garlic cloves, minced
1 tbsp fresh ginger, grated
1/2 cup soy sauce (or tamari for gluten-free)
1/3 cup brown sugar
1/4 cup water or beef broth
4 green onions, cut into 2-inch pieces
Optional: red pepper flakes, sesame oil
Toss the sliced beef in cornstarch and let sit for 10 minutes.
Combine soy sauce, sugar, water, garlic, and ginger in a bowl. Stir well.
Heat oil in a skillet or wok over medium-high. Sear beef in batches until browned and crisp. Remove from pan.
Add garlic and ginger to the pan and cook briefly until fragrant.
Pour in sauce and simmer until slightly thickened, about 2–3 minutes.
Return beef to the pan and toss to coat. Add green onions and cook for 1 more minute.
Serve hot with rice or noodles.
