Ingredient Guide

The foundation of this dish is flank steak, a lean, flavorful cut that cooks quickly and stays juicy when sliced thin. If you don’t have flank, sirloin or skirt steak will work just as well. The meat is typically marinated with soy sauce, vinegar, and cornstarch, which adds tenderness and helps it brown beautifully in the pan.

Bell peppers, usually a mix of red and green, bring color and a mild sweetness. Their crispness contrasts nicely with the soft, juicy beef. Onions, when cooked over high heat, turn slightly caramelized and mellow, adding balance to the bolder flavors in the sauce.

Fresh garlic and ginger are stir-fry essentials. They add a fragrant, zesty punch and bring out the depth of the other ingredients. The sauce—made with soy sauce, oyster sauce, sugar, and water—gets a boost from cornstarch, which gives it body and sheen. A few chili flakes can also be added if you want a spicy kick.

Finally, sesame oil adds a rich, nutty aroma right at the end, tying everything together with a warm, toasty finish.

Looking to switch things up? Try chicken, pork, or firm tofu instead of beef. For gluten-free cooking, use tamari or coconut aminos in place of soy sauce, and arrowroot starch instead of cornstarch.

Cooking Instructions

Step 1: Prep the meat.
Slice the steak into thin, even strips—always against the grain. Place the slices in a bowl and toss with 1 tablespoon soy sauce, 1 teaspoon rice vinegar, and 1 teaspoon cornstarch. Let the beef marinate for about 15 minutes to soak in the flavor and soften the texture.

Step 2: Get your ingredients ready.
While the beef marinates, prepare your vegetables. Slice the bell peppers and onions into strips. Mince the garlic and ginger so they’re ready when it’s time to cook.

Step 3: Mix the sauce.
In a small bowl, whisk together 1 tablespoon soy sauce, 1 tablespoon oyster sauce, 1 teaspoon sugar, 1 teaspoon cornstarch, and 1/4 cup water. Stir until smooth and set aside.

Step 4: Sear the steak.
Heat a tablespoon of oil in a large skillet or wok over high heat. When the oil is shimmering, add half the beef in a single layer. Sear for about 1–2 minutes on each side, then remove and repeat with the remaining beef.

Step 5: Cook the aromatics.
If the pan needs more oil, add a little before tossing in the garlic and ginger. Stir constantly for 30 seconds until they release their aroma.

Step 6: Stir-fry the veggies.
Add the onions and peppers to the pan and stir-fry for about 3 minutes. They should be slightly softened but still crisp enough to hold their shape.

Step 7: Combine everything.
Return the seared beef to the pan, pour in the sauce, and toss to coat. Let everything cook for another minute or two until the sauce thickens and clings to the meat and vegetables.

Step 8: Add the finishing touch.
Turn off the heat and drizzle in the sesame oil. Give the stir-fry one last toss, and it’s ready to serve.

To get the best results, avoid crowding the pan—cook the beef in batches. High heat is essential to get a good sear and prevent the vegetables from turning soggy.

Tips, Swaps & Flavor Ideas

If you want to make your steak ultra-tender, marinate it for 30 minutes instead of 15. Adding a tiny pinch (about 1/4 teaspoon) of baking soda to the marinade can also help break down the fibers, just like Chinese restaurants often do.

Love heat? Toss in sliced chili peppers, a dash of chili oil, or a spoonful of chili paste. Prefer something a little sweeter? Add a touch of hoisin sauce for a smooth, sweet finish.

Vegetarians can easily enjoy this dish by replacing the beef with tofu, tempeh, or even mushrooms. Gluten-free options include using coconut aminos and checking that your oyster sauce is certified gluten-free.

For more variety, add vegetables like baby corn, snap peas, or broccoli florets. Nuts like cashews or peanuts bring added texture and crunch.

Serving Suggestions

Serve your Chinese pepper steak hot over a bed of steamed jasmine rice for a classic pairing. Brown rice, quinoa, or noodles are great alternatives. If you’re cutting carbs, try cauliflower rice or wrap the steak in lettuce leaves for a lighter option.

To round out your meal, add a side of steamed bok choy, garlic green beans, or a crisp Asian cucumber salad. A light soup like egg drop or hot and sour soup also makes a great starter.

For drinks, go with jasmine tea, oolong, or even a lightly chilled white wine like Pinot Grigio or Gewürztraminer, which pairs well with the savory-sweet notes in the dish.

Frequently Asked Questions

1. What’s the best way to slice steak for stir-fry?
Always slice against the grain. This shortens the muscle fibers, making the beef easier to chew and more tender after cooking. Keep the slices thin for fast, even cooking.

2. Can I prepare this meal in advance?
Yes. You can slice and marinate the beef, prep the vegetables, and even mix the sauce ahead of time. Store everything in the fridge, and stir-fry just before serving.

3. How do I keep the steak from overcooking?
Sear it quickly over high heat. Cooking in small batches prevents the meat from steaming. As soon as it’s browned, remove it from the pan to avoid drying out.

4. Is this dish supposed to be spicy?
Not unless you want it to be. The base recipe is mild, but you can easily spice it up with chili flakes, hot sauce, or fresh chilies.

5. What other proteins can I use?
Chicken, pork, shrimp, or even tofu work great. Just adjust the cooking time—shrimp cooks faster, while chicken and pork need to be fully cooked through.

6. Can I use frozen peppers or onions?
You can, though fresh vegetables hold their texture better. If using frozen, thaw and pat them dry to avoid extra moisture that can dilute the sauce.

7. How do I thicken the sauce without cornstarch?
Arrowroot or potato starch are good alternatives. Another option is letting the sauce reduce naturally by simmering a little longer, though it may not be as glossy.
