Step‑by‑Step Instructions for Chinese Pepper Steak with Onions
Step 1: Marinate the Beef
In a medium bowl, combine sliced flank steak with soy sauce and cornstarch. Mix thoroughly to ensure each piece is evenly coated. Let the beef marinate for at least 10 minutes, allowing the flavors to meld and the cornstarch to tenderize the meat, making it juicy and flavorful when cooked.
Step 2: Sizzle the Beef
Heat a large skillet or wok over medium-high heat and add 2 tablespoons of vegetable oil. Once the oil shimmers, carefully add the marinated beef in a single layer. Stir-fry for about 5 minutes, or until the beef is browned and just cooked through. Remove the beef from the skillet and set it aside on a plate to keep warm.
Step 3: Cook the Vegetables
In the same skillet, add another tablespoon of vegetable oil if needed, and toss in the sliced red and green bell peppers along with the diced onion and minced garlic. Stir-fry for around 4 minutes, or until the vegetables are tender-crisp and vibrant in color, maintaining their freshness for a satisfying crunch in your Chinese Pepper Steak with Onions.
Step 4: Combine & Serve
Return the cooked beef to the skillet with the vegetables. Add the oyster sauce and a few cracks of black pepper, stirring everything together to ensure even coating and heating. Cook for an additional 2 minutes, allowing the flavors to meld beautifully. Serve your sizzling dish hot, ideally over a bed of steamed rice or noodles for a complete meal.
