How to Make Sizzling Chinese Pepper Steak with Onions
Step 1: Marinate the Beef
Start strong by tossing your thinly sliced flank steak or sirloin with soy sauce, oyster sauce, hoisin sauce, cornstarch, and rice vinegar in a large bowl. Use tongs or your hands to make sure every piece gets evenly coated. This quick marinade not only infuses delicious umami flavor but also gently tenderizes the meat. Let it sit for at least 15 minutes for quick flavor or longer if you have time.
Step 2: Sear the Beef
Get your skillet or wok nice and hot, then add a tablespoon of vegetable oil. Lay the marinated beef in a single layer—don’t overcrowd it; do it in batches if needed! Sear the beef for 2 to 3 minutes until browned on the outside, but not quite cooked through. Remove the beef to a plate; it’ll finish cooking soon and stay perfectly tender.
Step 3: Stir-Fry the Vegetables
In the same pan, add the remaining oil and toss in your sliced green and red bell peppers along with the onion. Keep the heat up and stir-fry for 3 to 4 minutes until they’re tender-crisp and slightly caramelized. The contrast of their softness and snap is key in Sizzling Chinese Pepper Steak with Onions.
Step 4: Add the Garlic and Return the Beef
Stir in the minced garlic and let it sizzle just until fragrant (about 30 seconds). Next, slide the reserved beef back into the pan along with all the collected juices—this is where the magic starts to happen.
Step 5: Season and Simmer
Sprinkle in the black pepper and pour in the beef broth (or water). Stir everything together so the beef, vegetables, and sauce combine beautifully. Let it cook for another 2 to 3 minutes until the sauce thickens slightly and the beef is cooked just to perfection.
Step 6: Serve Hot and Enjoy
Spoon heaps of Sizzling Chinese Pepper Steak with Onions over freshly steamed rice, making sure to get plenty of that glossy sauce. Serve immediately while everything is piping hot for the ultimate dinner treat.

Garnishes
Finish with a flourish by adding garnishes that lift both taste and appearance. Try a sprinkle of sliced scallions, a scatter of toasted sesame seeds, or even a little extra cracked black pepper for punch. A few cilantro leaves bring a pop of green and freshness, making every plate of Sizzling Chinese Pepper Steak with Onions extra inviting.
Side Dishes
This stir-fry is an adventurous main course, but it pairs so well with light, classic sides. Steamed jasmine or white rice is the top choice, but brown rice or fried rice work beautifully too. For a balanced meal, add steamed broccoli, sautéed bok choy, or a crisp Asian cucumber salad on the side.

Hosting friends or just want to jazz up weeknight dinner? Try serving Sizzling Chinese Pepper Steak with Onions from a sizzling cast iron platter, or plate individual servings in shallow bowls over rice for that “restaurant-style” look. For fun, wrap spoonfuls in lettuce leaves for a fresh, hand-held twist.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, let them cool completely before transferring to an airtight container. Sizzling Chinese Pepper Steak with Onions holds up beautifully for up to three days in the refrigerator, which means lunch tomorrow is already sorted!
Freezing
You can freeze Sizzling Chinese Pepper Steak with Onions, though the peppers and onions may soften a bit upon reheating. Divide cooled portions in freezer-safe bags or containers, removing as much air as possible; they’ll keep well for up to two months.
Reheating
For the best texture, reheat gently in a skillet over medium heat, stirring frequently until warmed through. If you’re in a hurry, the microwave works, but stir halfway to promote even heating. Add a splash of water or broth if the sauce has thickened too much.
FAQs
Can I use a different cut of beef for Sizzling Chinese Pepper Steak with Onions?

Is this recipe gluten free?

Can I make this dish vegetarian?

How do I prevent the beef from overcooking?
The key is to sear the beef quickly in a hot pan and then remove it before it’s fully cooked through. Finish cooking the beef with the vegetables at the very end—it stays juicy and tender every time.
What can I add for extra spice?
To amp up the heat, stir in a pinch of chili flakes or thinly sliced fresh chilies with the garlic, or offer chili oil on the side. Sizzling Chinese Pepper Steak with Onions adapts beautifully to your ideal spice level!
