Marinate the beef: Mix sliced beef with soy sauce, cornstarch, and sesame oil. Let sit for 15–20 minutes while prepping other ingredients.
Prepare the sauce: In a small bowl, whisk together soy sauce, oyster sauce, hoisin sauce, sugar, cornstarch, and beef broth.
Sear the beef: Heat 1 tbsp oil in a hot skillet or wok. Add beef in a single layer, cook undisturbed for 1–2 minutes, then stir-fry until browned but not overcooked. Remove and set aside.
Sauté veggies: In the same pan, add remaining oil. Sauté onions and bell peppers for 2–3 minutes until slightly softened but still crisp. Add garlic and ginger, stir for 30 seconds.
Combine & simmer: Return beef to the pan. Pour in the sauce and stir well to coat. Cook for 2–3 minutes until the sauce thickens and everything is sizzling.
