Ingredients

Scale
  • 1 pound flank steak or sirloin, thinly sliced against the grain
  • 1/2 cup cornstarch (60g)
  • 1/4 cup vegetable oil (60ml), canola or peanut oil as substitutes
  • 1/2 cup soy sauce (120ml), low-sodium preferred
  • 1/2 cup brown sugar (100g), packed
  • 1/2 cup water (120ml)
  • 3 cloves garlic, minced
  • 1 teaspoon grated fresh ginger (optional)
  • 1 tablespoon hoisin sauce (optional)
  • 1/4 teaspoon red pepper flakes (optional)
  • 34 stalks green onions, thinly sliced
  • 1 tablespoon sesame seeds (toasted optional)

Instructions

  1. Slice the beef thinly against the grain about 1/8 inch thick and set aside in a bowl.
  2. Place cornstarch in a shallow dish and toss beef slices in it, coating evenly. Shake off excess cornstarch.
  3. Heat vegetable oil in a large skillet or wok over medium-high heat until shimmering (2-3 minutes).
  4. Fry the coated beef in batches for 2-3 minutes per batch, turning occasionally until golden and crispy. Drain on paper towels.
  5. In a bowl, mix soy sauce, brown sugar, water, minced garlic, grated ginger, hoisin sauce, and red pepper flakes if using.
  6. Remove excess oil from skillet leaving about 1 tablespoon. Pour in sauce mixture and simmer over medium heat for 3-4 minutes until slightly thickened and glossy.
  7. Return crispy beef to skillet and toss quickly to coat evenly in sauce. Cook an additional 1-2 minutes.
  8. Remove from heat and garnish with sliced green onions and toasted sesame seeds.
  9. Serve immediately with steamed rice or stir-fried vegetables.

Notes

For gluten-free, substitute soy sauce with tamari and cornstarch with arrowroot powder. Avoid overcrowding the pan when frying to keep beef crispy. If sauce is not thickening, add a cornstarch slurry (1 tsp cornstarch + 1 tbsp cold water). Reheat leftovers gently in a skillet with a splash of water to maintain crispiness.
