How to Make It
Note: This is an overview. See recipe card below this post for ingredient quantities and full instructions.
1. Marinate the Beef Thinly slice flank steak against the grain (trust me, this keeps it tender!), then toss it with cornstarch and a splash of soy sauce. Let it hang out while you prep the sauce—this quick marinade ensures every bite stays juicy and soaks up flavor.
2. Sear the Beef Heat oil in a skillet until shimmering, then sear the beef in batches. Don’t crowd the pan! You want that golden-brown crust for maximum flavor. Once cooked, set it aside like a boss—resist the urge to stir too much!
3. Make the Sauce In the same skillet, sauté garlic and ginger until fragrant (about 30 seconds—don’t let them burn, or you’ll cry!). Pour in soy sauce, brown sugar, and a splash of water. Let it bubble and thicken into a sticky glaze that’ll make your taste buds do a happy dance.
4. Combine & Serve Toss the beef back into the sauce, coating every slice. Garnish with sesame seeds and green onions, then serve over rice or noodles. Dinner is done .
Pro Tips
Slice smart: Freeze the steak for 15 minutes first—it’s easier to cut thin, even strips.
Sear in batches: Overcrowding the pan = steamed beef. Sad times.
Adjust the heat: Add a pinch of red pepper flakes if you like it fiery.
Double the sauce: Extra for drizzling? Yes, please.
Storage
Fridge: Store leftovers in an airtight container for up to 3 days.
Reheat: Warm in a skillet over medium heat with a splash of water to revive the sauce.
Freeze: Sauce may separate, but flavor stays bomb. Thaw overnight in the fridge before reheating.
