Ingredients

Scale

Beef and Marinade

  • 1 pound flank steak, sliced thin against the grain
  • 2 tablespoons soy sauce
  • 1 tablespoon cornstarch

Vegetables

  • 1 large onion, sliced
  • 3 cloves garlic, minced
  • 1 bell pepper, sliced (any color)
  • 1 tablespoon ginger, minced

Sauces and Oils

  • 2 tablespoons vegetable oil
  • 1/4 cup beef broth
  • 2 tablespoons oyster sauce
  • 1 tablespoon sesame oil

Seasoning and Garnish

  • Salt and pepper to taste
  • Green onions, chopped (for garnish)

Instructions

  1. Marinate the Beef: In a bowl, combine the sliced flank steak with soy sauce and cornstarch. Mix until the beef is evenly coated. Allow the mixture to marinate for about 15 minutes to enhance flavor and tenderness.
  2. Cook the Beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the marinated beef and stir-fry for 3 to 4 minutes until it is browned but not fully cooked through. Remove the beef from the skillet and set aside to prevent overcooking.
  3. Stir-Fry Vegetables: In the same skillet, add the remaining tablespoon of vegetable oil. Toss in the sliced onion, bell pepper, and minced garlic. Stir-fry for approximately 3 to 5 minutes, until the vegetables become tender but still retain some crunch.
  4. Add Ginger: Incorporate the minced ginger into the skillet, stirring for about one minute to release its aromatic fragrance and deepen the flavor profile.
  5. Combine and Simmer: Return the browned beef to the skillet. Pour in the beef broth and oyster sauce, stirring to combine all ingredients. Continue cooking for an additional 2 to 3 minutes until everything is heated through and sauces have slightly thickened.
  6. Season and Garnish: Drizzle the sesame oil over the stir fry for a nutty finish. Season with salt and freshly ground pepper to taste. Remove from heat and garnish with chopped green onions before serving hot.

Notes

  • For extra heat, add sliced chili peppers or a pinch of red pepper flakes during the vegetable stir-fry stage.
  • Flank steak is preferred for its tenderness and flavor, but sirloin or skirt steak can be substituted if needed.
  • Serve this dish over steamed white or brown rice, or with noodles for a complete meal.
  • Adjust soy and oyster sauce quantities to control saltiness according to preference.
  • Ensure the beef is sliced thinly against the grain for maximum tenderness.
