How to Make Chinese Pepper Steak with Onions
Step 1: Marinate the Beef
Start things off by tossing your thinly sliced beef into a bowl with soy sauce, cornstarch, and just a pinch of freshly ground black pepper. Mixing these together isn’t just about flavor—it actually helps tenderize the beef, locking in juiciness. Let everything mingle for 10 to 15 minutes; while you prep the veggies, that flavorful marinade works its magic for perfect Chinese Pepper Steak with Onions.
Step 2: Cook the Beef
Grab your favorite large skillet or wok, and get it steaming-hot over medium-high heat. Swirl in a tablespoon of vegetable oil, then quickly add the marinated beef. Give it a speedy stir-fry (about 2 to 3 minutes), letting each slice sizzle and brown at the edges. You don’t want to cook it all the way through just yet—remove the beef and keep it handy for the next step.
Step 3: Cook the Vegetables
In that same irresistible pan, pour in the remaining oil. Toss in minced garlic for just a few seconds, letting it become beautifully fragrant. Then add your sliced onions and bell peppers. Sauté everything for around 3 to 4 minutes, stirring often until the veggies turn bright and stay wonderfully crisp-tender—this is where color and crunch come together for Chinese Pepper Steak with Onions perfection!
Step 4: Combine and Make the Sauce
Now, add the beef back into the pan along with the oyster sauce, the remaining soy sauce, another shake of black pepper, and the broth. Stir-fry everything for another 2 to 3 minutes, making sure every bite is coated and the sauce thickens to a gorgeous, glossy finish. This is the moment the flavors truly marry and transform!
Step 5: Serve
Spoon the fragrant, glistening pepper steak with onions over a bed of warm cooked rice. Serve it right away while the aromas are at their peak and the sauce is still luxuriously glossy. You’ll have the crowd oohing and ahhing with every bite!
How to Serve Chinese Pepper Steak with Onions

Garnishes
For a finishing touch, sprinkle your Chinese Pepper Steak with Onions with sliced green onions or a smattering of toasted sesame seeds. Either option adds visual pop and a burst of fresh flavor. Some people even love a small drizzle of extra soy sauce or a few pinches of red pepper flakes for extra heat.
Side Dishes
You can’t go wrong with a mound of steaming white or jasmine rice, which eagerly absorbs every drop of sauce. For something lighter, try simple stir-fried greens—bok choy or gai lan (Chinese broccoli) are traditional favorites. And if you’re feeling ambitious, veggie-packed spring rolls make a festive pairing.
Creative Ways to Present
For a playful dinner party, serve your Chinese Pepper Steak with Onions family-style on a beautiful platter. Or, for a bistro-style twist, mound individual servings in wide, shallow bowls with the rice on the side. A colorful stir-fry like this also looks striking in lettuce wraps for a fun, low-carb hand-held option.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers (lucky you!), store Chinese Pepper Steak with Onions in an airtight container in the refrigerator. The flavors deepen overnight, making it especially tasty as a next-day lunch or quick dinner.
Freezing
To freeze, let the dish cool completely before transferring to freezer-safe containers or zip bags. It keeps beautifully for up to three months. Just note that the peppers will soften a bit upon thawing, but the overall flavor remains fantastic.
Reheating
For best results, reheat Chinese Pepper Steak with Onions gently in a skillet over medium-low heat, adding a splash of broth or water to loosen the sauce if needed. You can also microwave individual portions, stirring halfway through. Serve it hot, right over fresh rice for a meal that tastes just-made.
FAQs
Can I use a different cut of beef?
Absolutely! While flank steak and sirloin are traditional for Chinese Pepper Steak with Onions, you can also use skirt steak, ribeye, or even thinly sliced round steak. Just be sure to cut against the grain for extra tenderness.
Is oyster sauce necessary?
Oyster sauce is what gives the sauce that classic depth and glossy finish, but if you need a substitute, try adding more soy sauce with a tiny bit of brown sugar and a few drops of Worcestershire. It won’t be exactly the same, but it’ll still be delicious.
Can I make this dish gluten-free?
Yes! Use gluten-free soy sauce (tamari) and check that your oyster sauce is gluten-free. Otherwise, the rest of the ingredients in Chinese Pepper Steak with Onions are naturally gluten-free, making this an easy weeknight win.
How do I keep the vegetables from getting soggy?
The secret is a hot pan and quick cooking. Sauté the bell peppers and onions just until they’re tender-crisp, not limp—usually three or four minutes is all you need. Avoid overcrowding the skillet, and don’t overcook!
What else can I add for extra flavor?
Feel free to stir in a splash of rice wine or Shaoxing wine, a little grated ginger, or even a handful of snow peas or mushrooms. Chinese Pepper Steak with Onions is flexible and invites your own creative tweaks.
