A Brief History of Pepper Steak
Pepper steak as we know it in Western kitchens is actually an adaptation of a Chinese dish called Qīngjiāo Ròusī (青椒肉丝), which literally translates to “green pepper shredded meat.” The original version from China often uses pork and features a light soy sauce base with fresh green peppers.
When Chinese immigrants brought the recipe to the United States in the early 20th century, beef was more readily available and popular with local palates. Over time, it evolved into the version you’ll find today — often with flank steak or sirloin, onions, and a slightly thicker, savory sauce that clings beautifully to each strip of meat.

Step-by-Step Instructions
Step 1: Prep the Beef
Slice the flank steak thinly against the grain (about ¼-inch thick). Cutting against the grain shortens muscle fibers, making each bite tender.
In a bowl, mix soy sauce, sesame oil, cornstarch, and baking soda (if using). Add beef, tossSizzling Chinese Pepper Steak with Onions to coat, and let marinate for 15–30 minutes while you prep vegetables.
Step 2: Make the Sauce
In a small bowl, whisk together soy sauce, oyster sauce, hoisin sauce, rice vinegar, beef broth, and black pepper. Set aside.
Step 3: Stir-Fry the Vegetables
Heat 1 tbsp oil in a large wok or skillet over high heat.
Add sliced onions and bell peppers. Stir-fry for 2–3 minutes until slightly softened but still crisp. Remove vegetables from the pan and set aside.
Step 4: Cook the Beef
Add remaining 1 tbsp oil to the wok.
Spread beef slices in a single layer. Let them sear for 30 seconds before stirring — this locks in juices.
Stir-fry beef for another 1–2 minutes until mostly cooked through.
Step 5: Combine Everything
Return vegetables to the pan with the beef.
Add garlic and ginger, stir-fry for 30 seconds until fragrant.
Pour in sauce and bring to a simmer.
Stir in cornstarch slurry and cook until sauce thickens and coats the beef and vegetables (about 1–2 minutes).
Step 6: Serve Hot & Sizzling
Serve immediately over steamed white rice, fried rice, or noodles. Garnish with sesame seeds or sliced green onions for an extra touch.
