Step 1: Marinate the Beef
In a bowl, toss the sliced beef with cornstarch, soy sauce, and oil.
Set aside for 10 minutes—this keeps the beef tender and juicy.
Step 2: Mix the Sauce
In a small bowl, whisk together soy sauce, oyster sauce, hoisin (if using), sugar, black pepper, and beef broth.
Set aside.
Step 3: Sear the Beef
Heat 1 tablespoon oil in a hot wok or large skillet over high heat.
Add beef in a single layer and sear for 1–2 minutes per side until just browned.
Remove and set aside (do not overcook).
Step 4: Stir-Fry the Vegetables
Add remaining oil to the pan.
Add onions and stir-fry for 1 minute.
Add bell peppers, garlic, and ginger. Stir-fry 2–3 minutes until crisp-tender.
Step 5: Combine & Sizzle
Return beef to the pan.
Pour in the sauce and toss everything together.
Cook 1–2 minutes until the sauce thickens and coats the beef beautifully.
Step 6: Serve Hot
Serve immediately while sizzling.
