This Black Pepper Beef Stir-Fry is a fast and flavorful stir-fry featuring tender strips of steak in a bold, peppery sauce. Inspired by Chinese cuisine, it combines garlic, onions, and bell peppers in a glossy, savory glaze enriched with oyster sauce and soy sauce. Quick to prepare and deeply satisfying, it’s ideal for a weeknight dinner or when you’re craving restaurant-style stir-fry at home.
Marinate the beef: Combine all marinade ingredients in a bowl with beef strips. Cover and refrigerate for 20 minutes.
Prepare the sauce: Whisk all sauce ingredients in a bowl and set aside.
Cook the beef: Heat half the vegetable oil in a wok over high heat. Add half the beef and stir-fry until golden brown, about 2-3 minutes. Repeat with remaining beef. Drain, leaving 2 tablespoons of oil.
Stir-fry garlic and veggies: Add garlic to the wok and cook until aromatic, about 30 seconds. Add onions and bell pepper, cooking for another minute.
Combine and serve: Return beef to the wok, add the black pepper sauce, and toss to combine. Drizzle with extra sesame oil and serve over rice.
