This classic stir-fry is loved for its tender beef, glossy sauce, and perfect balance of salty, sweet, and peppery flavors. Best of all, it’s surprisingly easy to make at home—faster than ordering takeout and far more satisfying.
This recipe delivers restaurant-quality results using simple ingredients and a smart cooking technique that keeps the beef juicy and the vegetables crisp. Whether served over steamed rice or noodles, this sizzling pepper steak is guaranteed to become a regular favorite.
Why This Pepper Steak Recipe Works
The secret to exceptional Chinese pepper steak lies in marinating the beef properly and cooking over high heat. A short marinade tenderizes the meat and infuses flavor, while quick stir-frying locks in moisture. Using fresh bell peppers and onions adds sweetness and crunch that perfectly contrast the savory sauce.
Unlike heavy, overly salty versions, this recipe creates a well-balanced sauce that lightly coats every bite without overpowering the dish.
Ingredients
For the Beef Marinade
-
1 lb flank steak or sirloin, thinly sliced against the grain
-
1 tablespoon soy sauce
-
1 tablespoon cornstarch
-
1 teaspoon sesame oil
-
1 teaspoon minced garlic
-
½ teaspoon freshly ground black pepper
For the Stir-Fry
-
2 tablespoons vegetable oil (divided)
-
1 large onion, sliced
-
1 green bell pepper, sliced
-
1 red bell pepper, sliced
For the Sauce
-
½ cup beef broth
-
2 tablespoons soy sauce
-
1 tablespoon oyster sauce
-
1 teaspoon sugar
-
1 teaspoon cornstarch
-
½ teaspoon black pepper (adjust to taste)
Step-by-Step Instructions
1. Marinate the Beef
Place the sliced beef in a bowl and add soy sauce, cornstarch, sesame oil, garlic, and black pepper. Mix well until every piece is coated. Let it marinate for at least 20 minutes. This step is essential for tender, flavorful beef.
2. Prepare the Sauce
In a small bowl, whisk together beef broth, soy sauce, oyster sauce, sugar, cornstarch, and black pepper. Set aside so it’s ready to use immediately during cooking.
3. Heat the Pan
Heat a large wok or heavy skillet over high heat until very hot. Add 1 tablespoon of oil and swirl to coat the pan.
4. Sear the Beef
Add the marinated beef in a single layer. Let it sear undisturbed for about 1 minute, then stir-fry for another 1–2 minutes until just browned. Remove the beef from the pan and set aside. Do not overcook.
5. Cook the Vegetables
Add the remaining tablespoon of oil to the pan. Toss in the onions and bell peppers. Stir-fry for 2–3 minutes until slightly tender but still crisp.
6. Combine and Sizzle
Return the beef to the pan with the vegetables. Pour in the prepared sauce and stir quickly. The sauce will thicken almost immediately, coating the beef and vegetables in a glossy sheen.
7. Finish and Serve
Cook for another 30–60 seconds, then remove from heat. Serve hot over steamed rice or noodles.
