Marinate the Beef

• In a bowl, combine the sliced beef with 2 tablespoons of soy sauce and 1 tablespoon of cornstarch.
• Mix well and let it marinate for at least 15 minutes while you prepare other ingredients.

Prepare the Sauce

• In a small bowl, whisk together the remaining soy sauce, oyster sauce, beef broth, and sesame oil.
• Set aside for later use in the stir-fry.

Blanch the Broccoli

• In a pot of boiling water, add the broccoli florets and blanch for 2-3 minutes until bright green and tender-crisp.
• Drain and rinse under cold water to stop the cooking process. Set aside.

Cook the Beef

• In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat.
• Add the marinated beef in a single layer and cook for 2-3 minutes until browned.
• Remove the beef from the pan and set aside.

Sauté Garlic and Ginger

• In the same skillet, add the remaining tablespoon of vegetable oil.
• Add the minced garlic and ginger, and sauté for about 30 seconds until fragrant.

Combine Ingredients

• Return the cooked beef to the skillet and add the blanched broccoli.
• Pour in the prepared sauce and toss everything together, cooking for an additional 2-3 minutes until heated through.

Serve

• Serve the Beef and Broccoli hot over cooked rice or noodles, garnished with sesame seeds if desired.
