Creating amazing Chinese Beef and Broccoli is straightforward. Follow these simple steps for success:

1. Prep the Ingredients: Begin by slicing the flank steak against the grain into thin strips. Prepare the broccoli florets and mince the garlic and ginger.
2. Make the Sauce: In a small bowl, combine soy sauce, oyster sauce, cornstarch, and beef broth. Stir until the cornstarch is fully dissolved, creating a smooth sauce mixture.
3. Heat the Pan: In a large skillet or wok, heat the vegetable oil over medium-high heat.
4. Cook the Beef: Add the sliced beef to the skillet in a single layer. Sear for about 2-3 minutes until browned. Remove from the pan and set aside.
5. Stir-fry Broccoli: In the same pan, add broccoli and stir-fry for 2 minutes. Add a splash of water to help steam and cook the broccoli until tender-crisp.
6. Add Aromatics: Add minced garlic and ginger to the broccoli, stirring for an additional 30 seconds until fragrant.
7. Combine Ingredients: Return the cooked beef to the pan. Pour the sauce mixture over the beef and broccoli, stirring to coat everything evenly.
8. Thicken the Sauce: Allow the mixture to simmer for about 2-3 minutes until the sauce thickens and coats the beef and broccoli.
9. Finish with Sesame Oil: Drizzle sesame oil over the top for an extra layer of flavor.
10. Serve Immediately: Remove from heat and serve hot over a bed of cooked rice.

These clear, concise steps will guide you to create a delicious dish that is both swift and satisfying.
