Chinese pepper steak is the stir-fry that started it all for so many home cooks — juicy slices of sirloin, colorful bell peppers and onions, and fresh tomato wedges all bathed in a savory, lightly thickened sauce that’s just the right balance of salty, sweet, and umami-rich. It’s a Chinese-American classic that’s impossible not to love, and it comes together in about 30 minutes.
The marinade is where the magic begins: a simple blend of soy sauce, white sugar, cornstarch, and ginger soaks into the beef and forms a silky sauce as it cooks. The tomatoes at the end might surprise you, but don’t skip them — they add a juicy, slightly acidic burst that makes the whole dish sing. Serve this over rice and watch it disappear from the table.

Ingredients
Main Ingredients
- 1 pound beef top sirloin steak, sliced thin across the grain
- ¼ cup soy sauce
- 2 tablespoons white sugar
- 2 tablespoons cornstarch
- ½ teaspoon ground ginger
- 3 tablespoons vegetable oil, divided
- 1 red onion, cut into 1-inch squares
- 1 green bell pepper, cut into 1-inch squares
- 2 ripe tomatoes, cut into wedges
Optional Add-ins
- Red bell pepper (adds sweetness and color)
- Mushrooms (cremini or button, sliced)
- Beef broth, ¼ cup (for a saucier result)
- Garlic, 2 cloves minced (adds another layer of depth)
- Sesame oil, 1 tsp (drizzle at the end for fragrance)
Step-by-Step Instructions
- In a medium bowl, whisk together the soy sauce, sugar, cornstarch, and ground ginger. Add the thinly sliced beef and toss to coat. Let marinate for at least 10 minutes (up to 30 minutes for deeper flavor).
- Heat 2 tablespoons of oil in a large wok or skillet over high heat until very hot and nearly smoking. Add the marinated beef (shaking off excess marinade, saving the leftover marinade) and stir-fry for 2–3 minutes until browned. Remove beef and set aside.
- Add the remaining tablespoon of oil to the pan. Add the red onion and green bell pepper and stir-fry for 3–4 minutes until tender-crisp.
- Return the beef to the pan. Pour the reserved marinade over everything and stir-fry for another 1–2 minutes until the sauce thickens and coats the beef and vegetables.
- Add the tomato wedges and toss gently, cooking just 1 minute — you want them warm and juicy, not cooked to mush.
- Serve immediately over steamed white or brown rice.
Pro Tips
- Slice the beef against the grain and as thin as possible — partially freezing the steak (20 min) makes this much easier.
- High heat is essential for proper stir-fry. If your pan starts to smoke, you’re doing it right.
- Don’t add the tomatoes too early — they should go in last to preserve their texture and fresh flavor.
- Save the marinade and add it to the pan — it thickens into a glossy sauce as it hits the heat.
- If you prefer a saucier dish, add 2–3 tablespoons of beef broth with the marinade.
Variations & Substitutions
Substitute chicken breast or pork tenderloin for the beef. Add sliced mushrooms and bamboo shoots for extra texture. Use two colors of bell peppers (red and yellow) for a more vibrant presentation. A teaspoon of oyster sauce stirred into the marinade adds incredible depth.
What to Serve With
Steamed jasmine rice is the classic companion. Egg fried rice or garlic noodles also pair wonderfully. Simple hot and sour soup or a cucumber salad on the side makes for a complete Chinese-inspired meal.
Storage & Reheating
Store in an airtight container in the refrigerator for up to 3 days. Reheat in a hot skillet with a splash of soy sauce or beef broth. The tomatoes will soften more on reheating, which is still delicious.
