directions
I start by slicing the flank steak thinly against the grain and tossing it with cornstarch to coat. Then, I quickly sear the beef in hot oil until it's just browned and tender. In the same pan, I prepare a simple sauce using soy sauce, water, brown sugar, garlic, and ginger. I let the sauce simmer until slightly thickened, then I return the beef to the pan and stir to coat every piece with the luscious sauce. Finally, I toss in sliced green onions and let everything cook together for a minute before serving.
Servings and timing
This recipe serves about 4 people. It takes roughly 10 minutes to prep and 15 minutes to cook, so I can have it ready in just 25 minutes.
Variations
Sometimes I swap the flank steak for sirloin or even chicken for a different twist. When I want a bit of heat, I add some red pepper flakes or sliced chilies. I also like adding vegetables like broccoli or snap peas for extra texture and freshness.
storage/reheating
I store leftovers in an airtight container in the refrigerator for up to 3 days. When I'm ready to reheat, I gently warm it in a skillet over medium heat, adding a splash of water to loosen the sauce if needed. Microwaving works too, but I prefer the stovetop for better texture.
