Before you start
Success with high-heat stir-frying depends entirely on preparation, a concept known as mise en place. Because the actual cooking process takes only a few minutes, there is absolutely no time to chop vegetables or mix sauces once the pan is hot.
Slice the beef, onions, and red bell peppers beforehand, and measure out the savory sauce into a small bowl. Arrange all your prepared ingredients in separate bowls next to your stove, along with a set of sturdy tongs.

- 1 1/2 lb flank steak, sliced against the grain into thin strips
- 1 large yellow onion, sliced
- 1 large red bell pepper, sliced
- 1/2 cup savory Chinese brown sauce
Instructions
Searing the Beef
- Preheat the CookwareHeat a heavy cast-iron platter over medium-low heat on one burner to get it thoroughly hot for serving. Simultaneously, heat a large wok or heavy skillet over high heat until it is smoking hot.Look for The wok should show faint wisps of smoke.Tip A hot pan is crucial to prevent the meat from sticking and steaming.
- Sear the BeefAdd the sliced beef strips to the smoking-hot wok in a single layer. Sear the meat without moving it for 1 minute to develop a deep brown crust. Toss and stir-fry for another 1 to 2 minutes until the beef is beautifully browned and reaches an internal temperature of 145°F (63°C). Transfer the seared beef to a plate and let it rest for 3 minutes.Look for The beef should be caramelized on the outside but still tender.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Cook in batches if your wok is not large enough to avoid overcrowding.
The beef strips should be deeply browned and caramelized on the outside, with a fragrant, savory aroma filling the air. You should see a beautiful crust formed on the meat, while the interior remains tender.
Ensure the beef is cooked to a safe internal temperature of 145°F (63°C) and allowed to rest for 3 minutes before combining with the vegetables.
Blistering the Vegetables
- Stir-Fry the VegetablesAdd the sliced onions and red bell peppers to the hot wok. Stir-fry over high heat for about 2 to 3 minutes, tossing constantly, until the vegetables are tender-crisp and show slight charred spots around the edges.Look for The onions should become translucent and the peppers slightly blistered.Tip Keep the vegetables moving constantly to ensure even cooking without burning.
The onions and red bell peppers should be slightly softened and charred around the edges, yet still vibrant and crisp. They will release a sweet, roasted aroma, and you will hear a loud, active crackling sound in the wok as they toss in the hot pan.
Glazing and Sizzling
- Glaze and SizzleReturn the rested beef and any accumulated juices to the wok with the vegetables. Pour the thick savory sauce over the mixture. Stir-fry rapidly for 1 minute until the sauce bubbles furiously and thickens into a glossy glaze that coats every piece. Carefully transfer the mixture onto the preheated, smoking-hot cast-iron platter and serve immediately.Look for The sauce should glaze the meat and sizzle loudly on the hot platter.Tip Use oven mitts when handling the extremely hot cast-iron platter.
The thick savory sauce should bubble furiously and reduce into a glossy, dark glaze that completely coats the beef, onions, and peppers. When transferred to the preheated cast-iron platter, the dish must sizzle intensely with a dramatic cloud of steam rising from the glossy surface.
Common mistakes
One of the most common mistakes when making pepper steak is overcrowding the wok or skillet. Dumping all the beef and vegetables into the pan at once lowers the cooking temperature drastically, causing the ingredients to steam in their own juices rather than sear.
This results in gray, tough meat and soggy, limp vegetables. To prevent this, always cook the beef in batches if necessary, allowing the pan to regain its intense heat between additions, and cook the vegetables separately.
How to tell it’s done
Determining the perfect doneness for this dish involves checking both the texture of the vegetables and the temperature of the meat. The red peppers and onions are done when they are translucent and tender-crisp, holding their shape without becoming mushy.
The beef strips must reach a safe internal temperature of 145°F (63°C) when measured with an instant-read thermometer, followed by a mandatory 3-minute rest period to allow the juices to redistribute throughout the meat, ensuring maximum tenderness.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
