Steps

• Place the thinly sliced beef sirloin in a mixing bowl. Add soy sauce, oyster sauce, cornstarch, and a drizzle of sesame oil. Mix well until all the slices are evenly coated. Allow this mixture to marinate for at least 15–30 minutes.
• While the beef is marinating, bring a pot of water to a boil and blanch the broccoli florets for about 2 minutes until they turn bright green and are crisp-tender. Drain and plunge them into ice water.
• Set a wok over high heat and add vegetable oil. Wait until the oil begins to shimmer slightly.
• Add the marinated beef to the hot wok in small batches to avoid overcrowding. Sear each side for about 2–3 minutes until browned and cooked through. Remove the beef from the wok and set aside.
• In the same wok, add minced garlic and ginger. Stir them quickly over high heat until fragrant.
• Return the beef to the wok along with the blanched broccoli. Pour in the beef broth and toss everything together to combine.
• Drizzle a dash of sesame oil over the stir-fry before serving.
