Ingredients

Scale

Main Ingredients

  • 8 oz flank steak, thinly sliced against the grain
  • 1/2 cup cornstarch
  • 2 tablespoons vegetable oil, for frying

Sauce Ingredients

  • 1/3 cup soy sauce
  • 2 tablespoons brown sugar
  • 2 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated
  • 1/4 cup water or beef broth

Garnish

  • 2 green onions, sliced
  • Optional: toasted sesame seeds

Instructions

  1. Prep the Beef: Thinly slice the flank steak against the grain to ensure tenderness. Pat the slices dry thoroughly to remove moisture. Toss the beef slices in cornstarch in a bowl until each piece is evenly coated. This step is essential for achieving the crispy crust.
  2. Make the Sauce: In a small bowl, whisk together soy sauce, brown sugar, minced garlic, grated ginger, and a splash of water or beef broth. This mixture will become the glossy, flavorful Mongolian sauce.
  3. Fry the Beef: Heat vegetable oil in a large skillet or wok over medium-high heat. Fry the coated beef strips in batches, avoiding overcrowding the pan to keep the oil hot and the beef crispy. Cook each batch until golden and crispy, then transfer to a paper towel-lined plate to drain excess oil.
  4. Combine and Simmer: Remove excess oil from the pan, then pour in the prepared sauce mixture. Let it simmer for 1-2 minutes until it thickens slightly. Return the crispy beef to the pan and toss quickly to coat each piece with the luscious sauce.
  5. Garnish and Serve: Sprinkle sliced green onions and toasted sesame seeds over the top just before serving. This adds freshness, a pop of color, and complementary textures to the dish.

Notes

  • Pat dry the beef thoroughly to ensure crispiness.
  • Fry the beef in small batches to avoid overcrowding the pan.
  • Use fresh garlic and ginger for best flavor.
  • To thicken the sauce further, add a cornstarch slurry (cornstarch mixed with water) near the end of cooking.
  • Serve immediately to maintain the crispy texture; the crust softens if left too long.
