Let’s talk about what you’ll need for this Chinese Pepper Steak with Onions. Every component is carefully chosen, with each ingredient lending its own magic to the finished dish— from the marinated steak to the crisp veggies and the deeply flavorful sauce. Here’s what to have ready:
- Flank steak or sirloin: Sliced thinly against the grain, this ensures your steak stays melt-in-your-mouth tender.
- Soy sauce (for marinade): Adds depth and that characteristic savory, umami punch right from the start.
- Cornstarch (for marinade and slurry): Locks in the steak’s moisture and helps the sauce finish with a silky gloss.
- Sesame oil: Just a touch infuses the meat with a delicate, nutty aroma.
- Vegetable oil: Ideal for high-heat stir-frying, ensuring the steak and veggies sear beautifully.
- Green and red bell peppers: Sliced for crunch and color, they bring a natural sweetness and pop to every bite.
- Onion: Adds mellow sweetness that perfectly balances the bite of the peppers.
- Garlic and fresh ginger: Minced for aromatic warmth and classic stir-fry depth.
- Soy sauce (for the sauce): The base of your rich, savory glaze.
- Oyster sauce: Offers umami layers that round out the sauce.
- Hoisin sauce: A hint of sweetness and earthiness that brings everything together.
- Rice vinegar: Adds a gentle tang and balances the sauce.
- Sugar: Just enough to highlight the savory notes without overpowering them.
- Beef or chicken broth: Lends a bit of body and ensures the sauce perfectly coats everything.
- Cornstarch slurry: This quick mix thickens the sauce to that glossy, restaurant-style finish.
How to Make Chinese Pepper Steak with Onions
Step 1: Marinate the Steak
Start by mixing your thinly sliced steak with soy sauce, cornstarch, and a drizzle of sesame oil. Give it a good toss so every piece is coated. This quick marinade not only infuses the meat with tons of flavor but also tenderizes it for that signature steakhouse texture. Let it sit for at least 15 to 20 minutes while you prepare the rest.
Step 2: Prepare the Sauce
This step is all about bringing together those unmistakable stir-fry flavors. Whisk the soy sauce, oyster sauce, hoisin, rice vinegar, sugar, and broth in a small bowl. Having your sauce ready before the pan hits the heat keeps everything quick and effortless when you start stir-frying.
Step 3: Cook the Steak
Pour a tablespoon of vegetable oil into a blazing hot skillet or wok. Add the marinated steak and quickly stir-fry for 2 to 3 minutes. The meat should brown nicely but not cook through just yet. Remove the steak to a plate, as you’ll return it to finish later so it stays juicy and tender.
Step 4: Stir-Fry the Vegetables
In the same pan, swirl the remaining oil and toss in the onions, both bell peppers, plus the minced garlic and ginger. Give them a fast, high-heat stir for 3 to 4 minutes until the veggies are just tender-crisp, their colors bright and flavors fragrant.
Step 5: Combine and Finish
Return the steak (and any juices) to the pan with the veggies. Pour in your pre-mixed sauce and stir to combine everything beautifully. Add the cornstarch slurry and cook for another 1 to 2 minutes. The sauce will thicken and cloak every bite with a glossy, full-bodied finish—this is the hallmark of a great Chinese Pepper Steak with Onions.
Step 6: Serve It Up
Spoon your Chinese Pepper Steak with Onions over a bed of steamed rice or toss with your favorite noodles. It’s ready to dazzle, whether for a cozy evening or a family feast.

Make Ahead and Storage
Storing Leftovers
Cool your Chinese Pepper Steak with Onions to room temperature before storing it in an airtight container. It keeps beautifully in the fridge for up to three days, making those weeknight lunches a flavor-packed treat.
Freezing
To freeze, transfer portions into freezer-safe containers or heavy-duty bags. Remove as much air as possible to avoid freezer burn. Your stir-fry will stay delicious for up to two months—simply thaw in the refrigerator before reheating.
Reheating
For best results, reheat gently in a skillet over medium heat, adding a splash of water or broth if the sauce needs loosening. Microwaving works in a pinch; just cover and stir occasionally to heat evenly without drying out.
FAQs
Can I use a different cut of beef?
Absolutely! Flank steak and sirloin are most common for their tenderness, but skirt steak or even ribeye will work beautifully. Just be sure to slice thinly against the grain for the most tender bites.
Do I have to use both red and green bell peppers?
Nope! Feel free to use whatever bell peppers you have on hand. The variety isn’t just for color; each type brings a slightly different sweetness, but all will taste delicious in Chinese Pepper Steak with Onions.
Is there a gluten-free option?
Yes, easily! Swap out regular soy sauce for a gluten-free tamari and double-check labels on your hoisin and oyster sauces. You’ll have a meal safe for gluten-sensitive guests that tastes just as divine.
Can I make this spicier?
You bet. Add freshly sliced chilies, toss in some chili garlic sauce, or finish with red pepper flakes. Adjust the heat to match your preference and enjoy a spicier take on Chinese Pepper Steak with Onions.
What’s the best way to slice the steak?
Pop your steak in the freezer for about 20 minutes before slicing—this firms it up so you can achieve super-thin, even strips. Always slice against the grain for the most tender texture in every mouthful.
