Chinese Pepper Steak with Onions is a classic stir-fry dish that combines tender strips of beef, crisp bell peppers, and sweet onions in a savory, slightly sweet sauce. Served over steamed rice, it’s a restaurant-style dish that’s easy to recreate at home. The key to this dish is quick cooking at high heat, which locks in the flavors, keeps the vegetables crisp, and results in a beautifully saucy, aromatic stir-fry.
This dish is beloved for its balance of textures and flavors. The beef is tender and flavorful, the bell peppers provide a slightly crunchy bite, and the onions add natural sweetness. A simple sauce of soy, oyster sauce, and a touch of sugar or cornstarch creates the signature glossy, savory coating that brings everything together. Perfect for busy weeknights, this stir-fry comes together in about 30 minutes, making it a practical yet impressive dish.
Ingredients
For the Stir-Fry:
-
1 pound flank steak or sirloin, thinly sliced against the grain
-
2 tablespoons soy sauce
-
1 tablespoon cornstarch
-
1 tablespoon vegetable oil (plus 1 tablespoon for stir-frying)
-
1 large onion, sliced into thin wedges
-
1–2 bell peppers (red, green, or yellow), sliced
-
3 cloves garlic, minced
-
1 teaspoon fresh ginger, grated (optional)
-
2 green onions, chopped (for garnish)
For the Sauce:
-
3 tablespoons soy sauce
-
1 tablespoon oyster sauce
-
1 teaspoon sesame oil
-
1 teaspoon sugar or honey
-
¼ cup beef broth or water
-
1 teaspoon cornstarch (optional, for thickening)
For Serving:
-
Steamed white rice or fried rice
Step 1: Marinate the Beef
In a bowl, combine the thinly sliced beef with 2 tablespoons soy sauce and 1 tablespoon cornstarch. Toss to coat evenly and let it marinate for at least 10–15 minutes. This helps tenderize the meat and gives it a flavorful coating that will help thicken the sauce slightly during cooking.
Step 2: Prepare the Sauce
In a small bowl, whisk together soy sauce, oyster sauce, sesame oil, sugar, and beef broth. If you prefer a thicker sauce, add 1 teaspoon of cornstarch to the mixture and whisk until smooth. Set aside. Preparing the sauce ahead ensures that the stir-fry comes together quickly without overcooking the vegetables.
Step 3: Cook the Beef
Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat. Once hot, add the beef in a single layer. Stir-fry for 2–3 minutes until the beef is just browned but not fully cooked through. Remove the beef from the skillet and set aside. Cooking the beef in batches if needed prevents overcrowding and ensures even searing.
Step 4: Sauté the Vegetables
In the same skillet, add another tablespoon of oil if needed. Add the sliced onions and bell peppers. Stir-fry for 3–4 minutes until they begin to soften but remain crisp. Add minced garlic and grated ginger and cook for an additional 30–60 seconds until fragrant. The vegetables should retain their color and crunch, adding freshness and texture to the dish.
Step 5: Combine Beef and Sauce
Return the beef to the skillet with the vegetables. Pour the prepared sauce over the mixture. Stir well to combine and cook for an additional 1–2 minutes, allowing the sauce to thicken slightly and coat the beef and vegetables evenly. Adjust seasoning with a pinch of salt or extra soy sauce if needed.
Step 6: Garnish and Serve
Transfer the sizzling pepper steak with onions to a serving plate. Garnish with chopped green onions or sesame seeds for extra flavor and presentation. Serve immediately over steamed white rice or fried rice to soak up the savory sauce. The combination of tender beef, crisp vegetables, and glossy, flavorful sauce makes this dish irresistible.
