- 1 lb flank steak thinly sliced against the grain
- 1/4 cup cornstarch
- 1/2 cup soy sauce low sodium preferred
- 1/2 cup brown sugar packed
- 3 cloves garlic minced

Slice flank steak thinly against the grain. Toss with cornstarch until lightly coated.
In a bowl, whisk together soy sauce, brown sugar, water, garlic, and ginger. Set aside.
Heat vegetable oil in a large skillet or wok over medium-high heat.
Cook beef in batches for 2–3 minutes until browned and slightly crispy. Remove and set aside.
Pour the sauce mixture into the skillet. Bring to a simmer and cook for 2–3 minutes until slightly thickened.
Return the beef to the pan and toss to coat with the sauce.
Stir in green onions and cook for another 1 minute.
Serve hot over white rice or noodles.
Marinate beef in soy sauce and cornstarch for 15 minutes before cooking for extra tenderness.
Add broccoli, snap peas, or bell peppers for a veggie boost.
Adjust sweetness by reducing brown sugar if desired.
