Ingredients You’ll Need
You only need a handful of staple ingredients to pull off this dish, but each is crucial for creating the authentic taste and texture that makes Chinese Pepper Steak with Onions so beloved. Think crisp peppers, juicy steak, and a punchy homemade sauce that ties everything together perfectly.
- Flank steak or sirloin: Thinly slicing the beef against the grain ensures tender bites that soak up all the good flavors.
- Soy sauce: Adds deep umami and saltiness, both in the marinade and the stir fry sauce.
- Cornstarch: Tenderizes the steak and thickens the sauce, giving everything that silky, restaurant-style finish.
- Vegetable oil: A neutral cooking oil is perfect for high-heat stir frying and keeps everything from sticking.
- Red and green bell peppers: These offer crunch and a splash of gorgeous color that make the dish extra inviting.
- Onion: Sliced onions bring natural sweetness and round out the stir fry’s flavors.
- Garlic: Just a couple cloves, minced, for essential aromatic depth.
- Fresh ginger: Grated ginger wakes up the dish with heat and brightness.
- Oyster sauce: This dark, slightly sweet sauce layers on complex, savory richness.
- Hoisin sauce: Adds sticky, sweet-savory notes and beautiful glaze to the sauce.
- Beef broth (or water): Helps the sauce cling to every bite and enhances meaty flavor.
- Brown sugar: Just a touch balances out the salt and brings subtle caramel notes.
- Sesame oil: A drizzle gives the dish its unmistakable, nutty Chinese fragrance.
- Crushed red pepper (optional): For those wanting a spicy kick, this brings some gentle heat.
How to Make Chinese Pepper Steak with Onions
Step 1: Marinate the Steak
Start by placing your thinly sliced beef in a mixing bowl and tossing it with soy sauce, cornstarch, and a splash of oil. Let the steak marinate for 15 to 20 minutes while you slice your peppers and onions. This quick soak works magic—your steak will be ultra-tender and flavorful within minutes.
Step 2: Prepare the Sauce
In a small bowl, whisk together all of those beautiful sauce ingredients: more soy sauce, oyster sauce, hoisin sauce, cornstarch, beef broth or water, brown sugar, and a little sesame oil. This combo is the secret to the restaurant-style taste and glossy finish you’ll love in Chinese Pepper Steak with Onions.
Step 3: Stir-Fry the Steak
Heat a tablespoon of oil in a hot wok or large skillet. Add the marinated beef in batches, spreading it out so every piece gets a nice sear. Sauté it for one to two minutes per side until just browned, then scoop the beef onto a plate—you don’t want to overcook these tender pieces!
Step 4: Cook the Vegetables
Pour the rest of your oil into the hot pan, then toss in the garlic and ginger for a quick sizzle. Add the sliced onions, red peppers, and green peppers, and stir fry for two to three minutes until they’re a little softened but still bright and crisp around the edges. That crunch is key to classic Chinese Pepper Steak with Onions.
Step 5: Combine Everything
Return your steak to the pan, pour in the tangy-sweet sauce, and give everything a hearty toss. Watch as the sauce thickens and becomes beautifully glossy, hugging every vibrant veggie and bite of beef. After another minute or two, you’ll have a pan full of irresistible goodness.
Step 6: Serve
Spoon your Chinese Pepper Steak with Onions fresh from the pan over hot, fluffy rice or noodles. Sprinkle with sesame seeds or a handful of chopped green onions if you’re feeling fancy—then dig in!

Side Dishes
This stir-fry shines with simple sides. Steamed jasmine rice will soak up all that delicious sauce, but egg fried rice or lo mein noodles are also fantastic. For extra veggies, a quick stir-fried bok choy, snow peas, or a fresh cucumber salad perfectly balances the richness of the steak and onions.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, let them cool before storing in an airtight container in the fridge. Chinese Pepper Steak with Onions keeps well for up to three days, and the flavors just get better as they mingle together.
Freezing
This dish actually freezes beautifully! Place cooled portions in freezer-safe containers or bags. Lay flat to save space and freeze for up to two months. Thaw overnight in the fridge for best results—your peppers may lose a touch of crunch but the flavor remains superb.
Reheating
To reheat, simply pop leftovers into a skillet or wok over medium heat with a splash of water or broth, stirring gently until warmed through. Microwave reheating works, too, but stovetop is best for keeping everything as tender and saucy as possible.
FAQs
Can I use a different cut of beef?
Absolutely! While flank steak or sirloin are most popular for their tenderness, you can substitute with ribeye or even skirt steak as long as you slice it thinly across the grain. Just adjust the searing time to suit the cut.
Is Chinese Pepper Steak with Onions very spicy?
Not at all—unless you want it to be! By default, this dish is mild and family-friendly, but a pinch of crushed red pepper is all you need if you like a little heat.
What’s the best way to slice the steak?
Be sure to cut the beef thinly against the grain. This breaks up the muscle fibers, keeping every bite buttery-soft after stir frying.
Can I add other vegetables?
Definitely! While bell peppers and onions are classic, feel free to throw in snow peas, baby corn, water chestnuts, or even broccoli for extra color and crunch.
Can I make Chinese Pepper Steak with Onions gluten-free?
Yes—just be sure to use gluten-free soy sauce (like tamari) and check that your oyster and hoisin sauces are certified gluten-free. The rest of the ingredients are naturally safe!
