Follow these easy steps to create your Beef and Broccoli dish:

1. Prep the Beef: Slice the flank steak thinly against the grain. This helps to ensure tenderness.
2. Marinate: In a bowl, combine the sliced beef with 1 tablespoon of soy sauce and cornstarch. Allow it to marinate for about 10 minutes.
3. Blanch the Broccoli: Bring a pot of water to a boil and quickly blanch the broccoli for 2-3 minutes. Drain and set aside.
4. Heat Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat until hot.
5. Sauté Beef: Add the marinated beef to the skillet. Stir-fry for about 2-3 minutes until browned and cooked through. Remove the beef from the pan and set aside.
6. Cook Garlic and Ginger: In the same skillet, add minced garlic and ginger. Sauté for about 30 seconds until fragrant.
7. Combine Ingredients: Return the beef to the skillet along with the blanched broccoli. Add the remaining soy sauce and oyster sauce. Stir well to coat everything.
8. Cook Together: Allow the mixture to cook for an additional 2-3 minutes, enabling the flavors to meld together beautifully.
9. Adjust Seasoning: Taste and season with salt and pepper as needed.
10. Serve: Serve hot over a bed of rice or noodles for a complete meal.

Following these steps, you’ll create a Beef and Broccoli dish that will be enjoyed by everyone at your table.
