Follow these simple steps to prepare Chinese Beef and Broccoli like a pro:

1. Slice the Beef: Begin by slicing the flank steak thinly against the grain. This will ensure tender, melt-in-your-mouth bites.
2. Marinate: In a bowl, combine the beef slices with 2 tablespoons of soy sauce and 1 tablespoon of cornstarch. Mix well and let it marinate for about 15 minutes.
3. Prepare the Sauce: In a separate bowl, whisk together the remaining soy sauce, oyster sauce, and beef broth. Set aside.
4. Blanch the Broccoli: While marinating, bring a pot of water to boil. Add the broccoli florets and blanch them for about 2 minutes. Remove and set aside.
5. Stir-Fry the Beef: In a large skillet or wok, heat vegetable oil over medium-high heat. Add the marinated beef slices in a single layer. Allow them to sear without stirring for about 1-2 minutes before flipping.
6. Add Aromatics: Once the beef is browned, add minced garlic and ginger to the pan. Stir and cook for an additional minute until fragrant.
7. Combine Ingredients: Add the blanched broccoli and the sauce mixture to the skillet. Stir well to coat everything evenly.
8. Thicken the Sauce: Allow the mixture to simmer for about 3-4 minutes until the sauce thickens. If needed, adjust seasoning with salt and pepper.
9. Serve: Remove from heat and serve hot over cooked rice.
