Ingredients:

  • 1 lb (450g) sirloin, ribeye, or flank steak, cut into 1-inch (2.5cm) cubes
  • 2 tablespoons (30ml) cornstarch
  • 1 tablespoon (15ml) vegetable oil, for searing
  • 2 tablespoons (30ml) soy sauce
  • 1 tablespoon (15ml) oyster sauce
  • 1 tablespoon (15ml) sesame oil
  • 1 tablespoon (15ml) rice vinegar
  • 1 tablespoon (15g) brown sugar
  • 3 cloves garlic, minced
  • 1 teaspoon (5g) fresh ginger, grated
  • 1 teaspoon (2g) red pepper flakes (optional)
  • Black pepper, to taste
  • 1 tablespoon sesame seeds
  • 2 green onions, thinly sliced
  • 2 limes, cut into wedges

Instructions:

  1. In a bowl, whisk together all marinade ingredients. Add steak cubes, toss to coat, and marinate in the refrigerator for at least 30 minutes, or up to 2 hours.
  2. Remove steak from marinade and pat dry with paper towels. This is crucial for a good sear!
  3. Lightly dust the steak cubes with cornstarch, ensuring each piece is evenly coated.
  4. Heat vegetable oil in a large skillet over medium-high heat until shimmering.
  5. Sear steak bites in a single layer (don't overcrowd the pan!) for 1-2 minutes per side, until browned and crispy on the outside, and juicy on the inside.
  6. Transfer to a serving plate. Sprinkle with sesame seeds and green onions. Serve hot with lime wedges.
