How to Make Chinese Pepper Steak with Onions
Step 1: Marinate the Steak
First, let’s get that steak soaking up all the good stuff. Combine the thin slices of flank steak with soy sauce, rice wine, cornstarch, and sesame oil in a bowl. Give it a good mix so every piece is coated. This marinating step, at least 15 to 20 minutes, is what tenderizes the meat and infuses it with flavor that will stand out after a quick sear.
Step 2: Prepare the Sauce
While the steak is marinating, blend together soy sauce, oyster sauce, hoisin sauce, sugar, black pepper, and broth. This sweet-and-savory mixture is going to bring all the ingredients together in the final step, so make sure it is well combined and ready to go.
Step 3: Cook the Steak
Heat one tablespoon of vegetable oil in a large skillet or wok over high heat to get it smoking hot. Add the marinated steak and stir-fry until it is just browned but not fully cooked through, about two to three minutes. Removing it early ensures the beef stays juicy and doesn’t overcook when combined with the veggies later. Set the steak aside.
Step 4: Stir-Fry the Vegetables
In the same pan, pour in the remaining oil and toss in the sliced onions, green and red bell peppers, minced garlic, and ginger. Stir-fry these aromatics until they’re tender-crisp, usually three to four minutes. The veggies should retain some crunch, providing a perfect balance to the tender steak.
Step 5: Combine and Finish
Return the steak to the pan along with the sauce mixture. Stir everything together and cook for another two to three minutes until the steak is cooked through and the sauce thickens slightly, beautifully coating the meat and vegetables. This final touch creates that signature glossy, flavorful dish that Chinese Pepper Steak with Onions is famous for.

Make Ahead and Storage
Storing Leftovers
Leftover Chinese Pepper Steak with Onions stores well in an airtight container in the refrigerator for up to three days. The flavors often deepen overnight, making it even tastier the next day.
Freezing
While best enjoyed fresh, you can freeze the cooked dish for up to two months. Cool it completely before packing it tightly into freezer-safe containers or bags, and thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers gently in a skillet over medium heat to maintain the steak’s tenderness and avoid drying out the vegetables. Adding a splash of broth or water can help rehydrate the sauce and keep everything from sticking to the pan.
FAQs
Can I use other cuts of beef for this recipe?
Yes, sirloin or ribeye thinly sliced against the grain works beautifully as well. The key is choosing a tender cut and slicing it very thin to ensure quick cooking and tenderness.
What if I don’t have oyster or hoisin sauce?
While these sauces bring authentic flavor, you can substitute with a mix of soy sauce and a bit of honey or molasses for sweetness. However, the taste will be slightly different but still delicious.
How do I make the steak extra tender?
Marinating the meat with cornstarch, soy sauce, and sesame oil helps tenderize it. Also, avoid overcooking by stir-frying the steak quickly over high heat and not letting it sit too long in the pan.
Can this dish be made vegetarian?
Absolutely! Swap the steak for firm tofu or mushrooms, and use vegetable broth instead. The same sauce and vegetables will work wonderfully to keep that vibrant flavor.
Is this recipe spicy?
This version isn’t overly spicy, focusing on the warmth of black pepper rather than heat. You can always add chili flakes or fresh chilis to kick up the spice if desired.
