What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 1.5 lb flank steak thinly sliced
  • 4 tbsp soy sauce
  • 3 tbsp brown sugar
  • 3 cloves garlic minced
  • 2 tbsp vegetable oil
  • 1 tsp fresh ginger grated

Step by step instructions

Step 1: Slice and Prep Beef

Slice flank steak as thin as possible against the grain for maximum tenderness. Thin slices are the key to fast and even cooking in this quick recipe.

Step 2: Sear the Beef

Heat vegetable oil in a wok or large skillet over high heat until smoking. Add beef slices in batches and sear for 1 to 2 minutes per side until browned.

Step 3: Make the Sauce

Add garlic and ginger to the pan and stir fry for 30 seconds. Pour in soy sauce and brown sugar and stir constantly for 2 minutes until the sauce thickens and glazes the beef.

Step 4: Serve

Serve over steamed rice topped with sliced green onions and a sprinkle of sesame seeds for an authentic finishing touch.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • flank steak → skirt steak or sirloin as equally quick cooking and tender cuts
  • brown sugar → coconut sugar for a slightly less refined sweetener alternative

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Slicing the beef too thick which requires longer cooking time and toughens the meat
  • Overcrowding the pan with all the beef at once which causes steaming instead of searing
