  • Total Time: 30 minutes
  • Yield: 4 servings 1x

Ingredients

Scale
  • 1 lb (450 g) flank steak or sirloin, thinly sliced
  • 2 tablespoons vegetable oil
  • 3 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated
  • 1/4 cup soy sauce
  • 1/4 cup hoisin sauce or oyster sauce (optional for extra flavor)
  • 1/4 cup water or beef broth
  • 1/4 cup brown sugar or honey
  • 1 teaspoon cornstarch mixed with 2 teaspoons water (for thickening)
  • Green onions, sliced (for garnish)
  • Sesame seeds (optional, for garnish)

Instructions

  1. Start by thinly slicing the beef against the grain. For easier slicing, you can partially freeze the beef for about 30 minutes. Set aside.
  2. Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the sliced beef and cook until browned and just cooked through, about 3-4 minutes. Remove from the pan and set aside.
  3. In the same skillet, add the remaining 1 tablespoon of oil. Sauté the minced garlic and grated ginger until fragrant, about 30 seconds.
  4. In a bowl, mix soy sauce, hoisin or oyster sauce (if using), water or broth, and brown sugar or honey. Pour this mixture into the skillet with the aromatics.
  5. Bring the sauce to a gentle simmer, then add the cornstarch mixed with water to thicken. Stir continuously until the sauce becomes glossy and slightly thickened, about 2 minutes.
  6. Return the cooked beef to the skillet, tossing to coat evenly with the sauce. Cook together for an additional 2-3 minutes until heated through and flavorful.
  7. Garnish with freshly sliced green onions and sesame seeds if desired. Serve hot over steamed rice or noodles for a complete meal.

Notes

  • Slice the beef very thinly against the grain for tender bites.
  • Adjust the sweetness or saltiness by varying the soy sauce and sugar amounts to suit your taste.
  • If you prefer more sauce, simply increase the soy and broth quantities, then thicken accordingly.
