Ingredients
  

  • 1 lb flank steak thinly sliced
  • 1/4 cup low-sodium soy sauce
  • 1/4 cup cornstarch
  • 3 tbsp brown sugar
  • 2 tbsp hoisin sauce
  • 1 tbsp rice vinegar
  • 1 tsp grated fresh ginger
  • 3 garlic cloves minced
  • 1/2 tsp red pepper flakes adjust for spice preference
  • 1/4 cup water
  • 2 tbsp vegetable oil
  • 4 green onions chopped (white and green parts separated)

Instructions
 

  • In a medium bowl, toss the sliced flank steak with cornstarch until every piece is evenly coated. Set aside while you make the sauce.
  • Whisk together soy sauce, brown sugar, hoisin sauce, rice vinegar, ginger, garlic, red pepper flakes, and water in a small bowl. Taste and adjust the sweetness or spice if needed.
  • Heat vegetable oil in a large skillet over medium-high heat. Add the beef in a single layer (work in batches to avoid steaming!) and cook for 2-3 minutes per side until golden brown. Remove the beef and set aside.
  • Reduce the heat to medium. Add the white parts of the green onions and sauté for 1 minute until fragrant. Pour in the sauce and let it simmer for 2-3 minutes until it thickens slightly.
  • Add the cooked beef back to the skillet. Toss everything together for 1-2 minutes until the sauce coats the beef evenly. Remove from heat and sprinkle with green onion tops.
