Ingredients
- Flank steak or sirloin: Thinly sliced across the grain ensures tenderness in the final dish
- Cornstarch: Creates that signature velvety texture on the beef you find in restaurant dishes
- Soy sauce: Provides the umami foundation for authentic Asian flavor
- Sesame oil: Adds a nutty depth that regular cooking oils cannot match
- Bell peppers: Both red and green offer contrasting sweetness and color
- Fresh garlic and ginger: Form the aromatic base that defines Chinese cuisine
- Oyster sauce: Delivers complex savory notes that elevate the entire dish
- Rice vinegar: Balances the flavors with subtle acidity
- Hoisin sauce: Adds sweetness and body to the sauce
How To Make Chinese Pepper Steak
- Marinate the beef:
- Toss thinly sliced beef with cornstarch and soy sauce until thoroughly coated. Let it rest for at least 15 minutes while you prepare other ingredients. This step tenderizes the meat and creates a protective coating that keeps it juicy during high-heat cooking.
- Prepare the signature sauce:
- Whisk together soy sauce, oyster sauce, rice vinegar, hoisin, sugar, and water until completely smooth. This balanced blend delivers the perfect combination of salty, sweet, and tangy notes that define great Chinese cooking.
- Sear the beef:
- Heat your wok or large skillet until it begins to smoke slightly before adding oil. Cook the marinated beef in a single layer without stirring for 1-2 minutes before tossing. Remove promptly when just browned to prevent overcooking.
- Stir-fry the vegetables:
- Using the same pan with its flavorful residue, cook the onions and peppers until they develop slight charring on the edges while maintaining their crispness. The vegetables should still have some bite when finished.
- Create the final dish:
- Return the beef to the pan with the vegetables and pour the sauce over everything. Toss continuously while the sauce thickens and coats each piece. The cornstarch from the beef will help create that glossy finish characteristic of restaurant-quality dishes.

I absolutely love the moment when the sauce hits the hot pan and creates that wonderful sizzling sound. It instantly transports me back to my favorite Chinese restaurant where I first fell in love with this dish. My family knows dinner is ready when they hear that distinctive sound from the kitchen.
Make-Ahead and Storage Tips
This pepper steak stores beautifully in airtight containers in the refrigerator for up to 4 days. The flavors actually intensify overnight making it perfect for meal prep. To reheat simply microwave until just warmed through or quickly toss in a hot skillet with a splash of water to revitalize the sauce. For longer storage you can freeze portions for up to 3 months though the peppers may lose some of their crisp texture when thawed.

Perfect Pairing Suggestions
While this dish is substantial enough to enjoy on its own I find it especially satisfying served over steamed jasmine rice which absorbs the flavorful sauce beautifully. For a lower-carb option cauliflower rice works wonderfully. Complete your homemade Chinese feast by adding simple sides like steamed broccoli or a quick cucumber salad dressed with rice vinegar and a touch of sugar. For special occasions serve alongside homemade egg rolls or dumplings.
Customization Options
The beauty of this recipe lies in its flexibility. Beef is traditional but chicken breast thinly sliced works excellently for a lighter version. Vegetarians can substitute firm tofu pressed and cubed or meaty mushrooms like portobello or king oyster. Feel free to adjust the vegetable mix based on what looks fresh at the market. Snow peas julienned carrots or water chestnuts add delightful texture and color variations. For those who enjoy heat add fresh sliced chilis or a teaspoon of chili garlic paste to the sauce.
Authentic Touch
For the most authentic experience use a carbon steel wok if you have one. The high sides and even heating create the perfect environment for quick stir-frying. Additionally consider adding a splash of Shaoxing wine to the sauce for depth of flavor that distinguishes restaurant-quality Chinese cuisine. Lastly garnish with sliced scallions cut on a diagonal and a sprinkle of white sesame seeds for visual appeal and textural contrast that completes the dish.
