Follow these simple instructions to create your Easy Beef and Broccoli Recipe:

1. Marinate the Beef: In a bowl, combine the sliced flank steak with soy sauce and let it marinate for at least 10 minutes while you prepare other ingredients.
2. Prepare the Sauce: In a small bowl, mix oyster sauce, cornstarch, water, and sesame oil. Set aside.
3. Heat the Pan: In a large skillet or wok, heat vegetable oil over medium-high heat.
4. Cook the Beef: Add the marinated beef to the skillet and stir-fry for about 3-4 minutes until it’s browned. Remove and set aside.
5. Cook the Broccoli: In the same skillet, add the broccoli florets along with a splash of water. Cover and steam for about 2-3 minutes until bright green but still crisp.
6. Combine Ingredients: Return the cooked beef to the skillet with the broccoli. Pour in the prepared sauce, stirring everything together.
7. Infuse Flavor: Add garlic and ginger to the skillet and stir-fry for an additional 2-3 minutes until fully cooked and the sauce thickens.
8. Season: Adjust seasoning with salt and pepper based on your taste.
9. Serve Immediately: Serve the beef and broccoli hot over cooked rice.

Following these steps will help ensure that your Easy Beef and Broccoli Recipe turns out perfectly every time!
