Step 1: Prepare the Beef

Thinly slice the beef against the grain into bite-sized strips.

In a bowl, combine the sliced beef with 2 tablespoons of soy sauce and the cornstarch. Mix well and let it marinate for about 10 minutes.

Step 2: Prepare the Broccoli

In a pot of boiling water, blanch the broccoli florets for about 2 minutes until bright green and slightly tender. Drain and immediately transfer to a bowl of ice water to stop the cooking process. Drain again and set aside.

Step 3: Cook the Beef

In a large skillet or wok, heat the olive oil over medium-high heat.

Add the marinated beef to the skillet in a single layer. Cook for about 2–3 minutes until browned, stirring occasionally. Remove the beef from the skillet and set aside.

Step 4: Cook the Vegetables

In the same skillet, add a little more oil if needed. Add the minced garlic and grated ginger, sautéing for about 30 seconds until fragrant.

Add the blanched broccoli to the skillet and stir-fry for another 2–3 minutes.

Step 5: Combine and Finish

Add the cooked beef back to the skillet with the broccoli.

In a small bowl, whisk together the remaining soy sauce, oyster sauce (if using), and beef broth. Pour this sauce over the beef and broccoli.

Stir everything together and cook for another 2–3 minutes until the sauce thickens slightly and the beef is heated through.

Step 6: Serve

Serve the beef and broccoli over cooked brown rice or quinoa.

Sprinkle with sesame seeds if desired.
