Tender strips of flank steak seared until golden and coated in a sweet, savory Mongolian-style sauce with garlic, ginger, and green onions. Better than takeout!
1 lb flank steak, sliced thin against the grain
¼ cup cornstarch
2–3 tbsp oil (for searing)
4 green onions, cut into 2-inch pieces
Sauce
½ cup low-sodium soy sauce
⅓ cup brown sugar
¼ cup water or beef broth
1 tsp sesame oil
2 cloves garlic, minced
1 tbsp grated fresh ginger
¼–½ tsp red pepper flakes (optional)
Coat steak strips in cornstarch and let rest 10 minutes.
Mix sauce ingredients in a bowl and set aside.
Sear beef in hot oil over medium-high heat until browned. Work in batches if needed. Remove to a plate.
Pour sauce into the pan and bring to a boil. Simmer 2–3 minutes until slightly thick.
Return beef to the pan, add green onions, and toss to coat.
Cook 1–2 more minutes. Serve over rice or noodles.
Customize spice level with chili flakes or chili oil. Add broccoli or bell peppers for extra veggies. Use tamari for a gluten-free version.
