Why You’ll Love This Pepper Steak
Chinese Pepper Steak is a nostalgic favorite for many. The blend of juicy beef slices, colorful peppers, and sweet onions bathed in a savory sauce has wide appeal and can be tailored in countless ways. You can make it mild or spicy, add different vegetables, or adjust the sweetness or saltiness to your taste.
The dish is economical, too—flank steak, while flavorful, is relatively affordable, especially when stretched across a large stir-fry. The ingredients are common pantry items, and the prep is straightforward. With one pan, one bowl of sauce, and a hot flame, you’ve got everything you need.
Ingredients You’ll Need
For the Marinade and Beef:
- 1 lb flank steak, thinly sliced against the grain
- 2 tablespoons soy sauce
- 1 tablespoon cornstarch
- 1 tablespoon vegetable oil (for marinating)
For Stir-Frying:
- 2 tablespoons vegetable oil (for cooking)
- 1 large onion, thinly sliced
- 1 bell pepper (any color, or a mix), thinly sliced
- 2-3 cloves garlic, minced
- 1 tablespoon fresh ginger, minced
For the Sauce:
- 1/2 cup beef broth
- 2 tablespoons soy sauce (or low sodium)
- 1 tablespoon oyster sauce (optional, for added umami)
- 1 tablespoon hoisin sauce (optional, for sweetness and depth)
- 1 tablespoon rice vinegar (or other mild vinegar)
- 1 teaspoon sugar (or honey)
- 1 tablespoon cornstarch
- 2 tablespoons water (to make a slurry)
- 1/4 teaspoon freshly ground black pepper
- Optional: pinch of red pepper flakes for heat
- Optional: 1 teaspoon sesame oil (for finishing)
For Serving:
- Cooked white or jasmine rice
- Optional garnish: chopped green onions or sesame seeds
The Importance of Proper Slicing
Before you begin cooking, ensure your flank steak is sliced thinly and against the grain. This technique shortens the muscle fibers in the meat, resulting in a more tender bite. If slicing raw meat feels tricky, partially freeze the steak for 15 to 20 minutes—this firms it up and makes slicing easier and more precise.
Step-by-Step Instructions
1. Marinate the Steak
Place your thinly sliced flank steak in a medium mixing bowl. Add the soy sauce, cornstarch, and one tablespoon of vegetable oil. Toss everything together to coat the meat evenly. Let it sit and marinate for at least 15 minutes. This short marinade helps the meat absorb flavor while the cornstarch forms a protective layer that gives it a velvety texture once cooked.
2. Prepare the Sauce
In a small bowl, whisk together the beef broth, soy sauce, oyster sauce, hoisin sauce, rice vinegar, sugar (or honey), black pepper, and red pepper flakes if you like heat. In a separate bowl or measuring cup, mix the cornstarch with two tablespoons of water to create a smooth slurry. Set both mixtures aside near your stovetop.
3. Sear the Steak
Heat two tablespoons of vegetable oil in a large wok or heavy skillet over medium-high heat until shimmering. Working in batches to avoid overcrowding, add the marinated steak slices in a single layer. Sear them for about 1 to 2 minutes per side, or until lightly browned and just cooked through. Remove the steak from the pan and set aside on a plate. Don’t worry if the meat isn’t fully cooked—it will finish cooking later when combined with the sauce.
4. Stir-Fry the Vegetables
In the same pan, add a bit more oil if needed. Toss in the sliced onions and bell peppers. Stir-fry for about 2 to 3 minutes, or until the onions are slightly translucent and the peppers are tender-crisp. Add the minced garlic and ginger and cook for another 30 seconds until fragrant.
5. Combine and Simmer
Return the seared steak to the pan with the vegetables. Stir everything to combine. Pour in the sauce mixture and stir well. Bring the mixture to a simmer.
While the pan is heating, give your cornstarch slurry a final stir (it tends to settle) and then drizzle it into the bubbling sauce. Stir immediately and continuously. The sauce will thicken within 30 seconds to a glossy coating that clings to the beef and vegetables.
6. Final Touches
Turn off the heat and stir in the optional sesame oil for a nutty aroma. Taste and adjust the seasoning—add a splash more soy sauce if you prefer saltier, or a pinch of sugar if you want more balance. Serve immediately over hot steamed rice.
Serving Suggestions
The beauty of this dish is in its simplicity and adaptability. Here are some serving ideas to make your pepper steak meal even more memorable:
- Serve over freshly steamed jasmine rice or short-grain sticky rice.
- Add a side of stir-fried greens like bok choy, Chinese broccoli, or snap peas.
- Include a fried or soft-boiled egg for added richness.
- Serve with rice noodles or lo mein for a fun twist.
Helpful Tips for Perfect Results
- Use high heat: Stir-frying is all about fast cooking at high temperatures. This ensures that ingredients sear instead of steam and that flavors stay vibrant.
- Don’t overcrowd the pan: Especially when cooking the beef, too much in the pan at once will cause the meat to steam instead of sear.
- Pre-slice everything: Stir-frying moves fast. Have all your vegetables, meat, and sauce ready before you turn on the heat.
- Deglaze with a splash of broth: If your pan develops browned bits during cooking, add a small splash of beef broth to lift the flavor off the bottom.
