Ingredients:
- For the Steak Marinade:
- 1 lb flank steak, thinly sliced against the grain
- 1 tablespoon soy sauce
- 1 teaspoon freshly ground black pepper
- 1 tablespoon cornstarch
- For the Stir-Fry:
- 2 bell peppers, sliced (1 red, 1 green for color contrast)
- 1 large onion, sliced into half-moon shapes
- 3 cloves garlic, minced
- 1 tablespoon oyster sauce
- 1 teaspoon sugar
- 1/4 cup water
- 2 tablespoons vegetable oil (divided use)
- 1/4 teaspoon sesame oil (optional, for a nutty flavor)
- Optional Garnishes:
- Sesame seeds
- Thinly sliced green onions or scallions
- Extra ground black pepper for a spicier kick
Directions:
- Prepare the Steak:
Begin by slicing the flank steak thinly against the grain. This step is crucial for tender bites of steak, as cutting against the grain shortens the meat fibers. - Marinate the Steak:
In a bowl, combine the sliced steak with soy sauce, black pepper, and cornstarch. Mix well to ensure the steak is evenly coated. Let it marinate for about 10 minutes. The cornstarch will help seal in moisture, making the steak tender while giving it a slight crispness when cooked. - Prep the Vegetables:
While the steak is marinating, wash and slice the bell peppers into thin strips. Slice the onion into thin half-moon shapes for even cooking. Mince the garlic finely, ensuring no large chunks remain. Keep all the prepped vegetables nearby for quick cooking. - Cook the Steak:
Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Once the oil is shimmering but not smoking, add the marinated steak in a single layer. Stir-fry for about 3-4 minutes, allowing the edges to brown slightly. Avoid overcrowding the pan to ensure even cooking. Remove the cooked steak from the skillet and set aside. - Stir-Fry Aromatics and Vegetables:
In the same skillet, add the remaining tablespoon of oil. Reduce the heat slightly and add the minced garlic. Stir-fry for about 30 seconds, just until fragrant. Be careful not to burn it.
Next, add the sliced onions and bell peppers. Stir-fry for 2-3 minutes, tossing frequently to prevent burning. Cook until the vegetables are tender but still crisp, maintaining their vibrant colors. - Make the Sauce:
While the vegetables cook, mix the oyster sauce, water, sugar, and sesame oil (if using) in a small bowl. Stir until the sugar dissolves completely. This creates a flavorful sauce with a balance of umami, sweetness, and a slight nuttiness from the sesame oil. - Combine Steak, Vegetables, and Sauce:
Return the cooked steak to the skillet, along with the sauce. Toss everything together, ensuring the sauce evenly coats the steak and vegetables. Cook for an additional 2-3 minutes over medium heat, allowing the sauce to thicken slightly. The cornstarch from the steak marinade will help the sauce cling to the ingredients. - Finish and Serve:
Remove the skillet from heat and transfer the sizzling Chinese pepper steak with onions to a serving platter. Garnish with a sprinkle of sesame seeds and sliced green onions for a pop of color and added crunch. Add an extra grind of black pepper for a spicier flavor, if desired. - Pairing Suggestions:
Serve the dish immediately with a side of steamed white rice, brown rice, or fried rice. For a low-carb option, pair it with cauliflower rice or stir-fried zucchini noodles. This dish also pairs well with a light, crunchy side salad dressed in sesame vinaigrette or a bowl of hot and sour soup for a complete meal. - Pro Tips for Success:
- For a smoky, restaurant-style flavor, use a well-seasoned wok over high heat.
- To achieve vibrant vegetables, avoid overcooking them during the stir-fry. Aim for a tender-crisp texture.
- Add chili flakes or sliced fresh chilies to the stir-fry for a spicier version of this dish.
- For an even more tender steak, marinate it for 20-30 minutes (instead of 10) if time allows.
