Ingredients:
- 1½ pounds flank steak, cut into thin strips
- ½ teaspoon baking soda
- 2 tablespoons low sodium soy sauce (for marinade)
- 1 teaspoon sesame oil
- ½ teaspoon white pepper
- 1 tablespoon cornstarch (for marinade)
- ¼ cup oyster sauce
- 1 teaspoon ground Sichuan peppercorn
- 2 teaspoons coarsely ground black pepper
- 3 tablespoons Shaoxing vinegar
- 2 tablespoons low sodium soy sauce (for sauce)
- 1 teaspoon dark soy sauce
- 1 teaspoon sugar
- 1 tablespoon cornstarch (for sauce)
- ⅓ cup vegetable oil (for stir-frying)
Preparing the Beef for Ultimate Tenderness
Marinating the Flank Steak
The key to incredibly tender and flavorful Black Pepper Beef lies in the marinade. We’ll start by preparing the flank steak. Ensure your flank steak is cut against the grain into thin strips, about ¼-inch thick. This is crucial for a tender bite. In a medium bowl, combine the thinly sliced flank steak with ½ teaspoon of baking soda, 2 tablespoons of low sodium soy sauce, 1 teaspoon of sesame oil, ½ teaspoon of white pepper, and 1 tablespoon of cornstarch. The baking soda works wonders by tenderizing the meat at a cellular level, making it remarkably soft. The soy sauce adds depth of flavor and saltiness, while the sesame oil provides a subtle nutty aroma. Cornstarch acts as a binder and also helps create a protective coating on the meat, which will keep it moist during the high-heat cooking process. Toss everything together thoroughly, ensuring each strip of beef is well-coated. Cover the bowl and let it marinate in the refrigerator for at least 30 minutes, or ideally for 1 to 2 hours. This allows the flavors to penetrate the meat and the tenderizing agents to work their magic.
Crafting the Signature Black Pepper Sauce
The Flavor Foundation
Now, let’s build the foundation of our irresistible Black Pepper Beef sauce. In a separate small bowl, whisk together ¼ cup of oyster sauce, 1 teaspoon of ground Sichuan peppercorn, 2 teaspoons of coarsely ground black pepper, 3 tablespoons of Shaoxing vinegar, 2 tablespoons of low sodium soy sauce, 1 teaspoon of dark soy sauce, and 1 teaspoon of sugar. This combination is where the magic happens. Oyster sauce provides a rich, savory umami base. The star, Sichuan peppercorn, offers its unique numbing and citrusy notes that are characteristic of authentic Black Pepper Beef, so don’t skip this! Coarsely ground black pepper provides the robust peppery punch. Shaoxing vinegar adds a balancing acidity that cuts through the richness and brightens the overall flavor profile. The dark soy sauce contributes a deeper color and a more complex soy flavor, while the sugar balances the saltiness and acidity, creating a harmonious blend. Set this sauce mixture aside.
Thickening the Sauce
Before we start stir-frying, we need to prepare the thickening slurry for our sauce. In another very small bowl, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water, stirring until it forms a smooth paste. This slurry will be added at the end of the cooking process to give the sauce a beautiful, glossy consistency that coats the beef perfectly.
The Searing and Stir-Frying Process
High Heat for Perfect Sear
This is where all your preparation comes together for a speedy and satisfying stir-fry. Heat ⅓ cup of vegetable oil in a wok or a large, heavy-bottomed skillet over high heat until it is shimmering and almost smoking. It’s crucial to have the oil very hot to achieve a proper sear on the beef. Add the marinated flank steak in a single layer, working in batches if necessary to avoid overcrowding the pan. Overcrowding will steam the meat instead of searing it, resulting in a less desirable texture. Sear the beef for about 1 to 2 minutes per side, until it’s nicely browned and slightly caramelized. The high heat and short cooking time ensure that the beef remains tender and juicy inside. Once seared, remove the beef from the wok and set it aside on a plate. Do not clean the wok; the browned bits left behind will add immense flavor to the sauce.
Building the Stir-Fry
With the beef seared, it’s time to finish the dish. If there’s excessive oil in the wok, carefully pour out all but about 1 tablespoon. Return the wok to medium-high heat. Pour in the prepared Black Pepper Beef sauce mixture. Bring the sauce to a simmer, stirring constantly. As the sauce begin extracts to bubble, slowly pour in the cornstarch slurry while stirring continuously. The sauce will thicken rapidly to a glossy, rich consistency. Once the sauce has thickened to your liking, return the seared beef to the wok. Toss the beef gently in the sauce to ensure every piece is thoroughly coated. Continue to stir-fry for another 30 seconds to 1 minute, just long enough to heat the beef through and allow it to absorb the delicious sauce. Be careful not to overcook at this stage, as the beef is already cooked from searing. The final result should be glossy, tender beef coated in a rich, peppery sauce.

Frequently Asked Questions about Black Pepper Beef:
Q1: Can I make Black Pepper Beef ahead of time?
Yes, you can! The sauce can be made in advance and stored in the refrigerator. For the beef, it’s best to stir-fry it just before serving to ensure it remains tender and juicy. You can marinate the beef beforehand, though. This will allow the flavors to meld beautifully and will make the cooking process even quicker.
Q2: What kind of beef is best for Black Pepper Beef?
For the most tender and flavorful Black Pepper Beef, I recommend using cuts like flank steak, sirloin, or even tenderloin. These cuts have a good balance of flavor and texture that work wonderfully with the sauce. Make sure to slice the beef thinly against the grain for maximum tenderness.
