Instructions
- Marinate the Steak – In a bowl, mix the sliced steak with cornstarch, soy sauce, and black pepper. Let it marinate for 15 minutes.
- Prepare the Sauce – In a small bowl, whisk together oyster sauce, hoisin sauce, rice vinegar, sesame oil, beef broth, and brown sugar. Set aside.
- Cook the Steak – Heat vegetable oil in a large skillet or wok over high heat. Add steak in a single layer and cook until browned, about 2 minutes per side. Remove and set aside.
- Sauté Vegetables – In the same pan, add a little more oil if needed. Sauté garlic, ginger, and onions for about 1 minute. Then, add bell peppers and stir-fry for 2–3 minutes until slightly tender.
- Combine & Simmer – Return the steak to the pan, pour in the sauce, and stir well. Let it simmer for 2 minutes. Stir in the cornstarch slurry and cook until the sauce thickens.
- Serve & Enjoy – Remove from heat and serve hot over rice.
