This black pepper beef stir fry has become my go-to dinner when I'm craving Chinese takeout but don't want to wait for delivery. I discovered this recipe a few years back when trying to recreate my favorite dish from our local Chinese restaurant, and honestly, I think this homemade version is even better. The beef turns out incredibly tender thanks to a simple marinade trick, and that sauce – intensely savory with a perfect kick of black pepper – will have you licking your plate clean.
Last month, I made this for my brother who always orders black pepper beef when we get takeout. He took one bite and said, 'Why have we been paying $18 for this when it tastes better at home?' Then proceeded to shovel it down so fast I barely got any myself. I've had to double the recipe ever since.
Key Ingredients
- Flank steak: This cut has great beef flavor and becomes tender when sliced properly against the grain. Skirt steak or sirloin work well too.
- Baking soda: Don't skip this! It's the secret to velvety-tender beef that high-end Chinese restaurants use. Just a small amount transforms the texture completely.
- Sichuan peppercorns: These add that authentic numbing quality that makes this dish special. If you can't find them, black pepper alone still makes a delicious dish.
- Shaoxing wine: This Chinese cooking wine adds incredible depth. Dry sherry makes a decent substitute in a pinch.
- Dark soy sauce: Adds color and a richer flavor than regular soy sauce. Even that small teaspoon makes a difference in the final dish.

Stir-Fry Success
- Prep your beef right:
- Slice your steak thinly against the grain – this is crucial for tenderness. Partially freezing the meat for about 20 minutes makes it easier to get those thin, even slices.
- The magic marinade:
- Don't skip the baking soda in the marinade! This simple ingredient breaks down the meat fibers and gives you that silky-tender texture you get at good Chinese restaurants. The full 20-minute marinade time is worth it.
- Sauce strategy:
- Mix your sauce ingredients before you start cooking. Stir-frying moves quickly, and having your sauce ready to go prevents anything from burning while you're measuring ingredients.
- Hot wok, cold oil:
- Get your wok or skillet really hot before adding the oil. This prevents sticking and gives you that proper sear on the beef that builds amazing flavor.
- Cook in batches:
- Don't crowd the pan when cooking the beef. Working in batches ensures each piece gets nicely browned instead of steaming in its own juices.
- Vegetable timing:
- The onions and peppers only need a quick cook – you want them to retain some crispness to contrast with the tender beef. About a minute is perfect for that slight char while keeping their texture.
I developed this recipe after getting tired of spending $40+ on Chinese delivery that would arrive lukewarm and soggy. The first few attempts were decent but missing something, until I discovered the baking soda trick from an old Chinese cookbook my neighbor gave me. That, combined with getting the pepper balance right, finally nailed that authentic flavor I was chasing. Now my family actually prefers this to any restaurant version.
Serving Ideas
Serve this over steamed jasmine rice to soak up all that amazing sauce. For a complete meal, add a simple side of steamed broccoli or bok choy. If you're watching carbs, it's equally delicious over cauliflower rice or wrapped in lettuce cups.
Tasty Twists
Add sliced mushrooms along with the onions and peppers for an earthy flavor boost. Include some thinly sliced carrots or snow peas for extra color and nutrition. For heat lovers, toss in a sliced fresh chili or two with the garlic.
Storage Smarts
This stir-fry keeps beautifully in the fridge for up to 4 days, making it perfect for meal prep. The flavors actually deepen overnight! Reheat gently in a skillet with a splash of water to bring it back to life. For freezing, cool completely before storing in airtight containers for up to 3 months.

I've made this black pepper beef countless times – for quick weeknight dinners, for friends who claim they 'don't like Chinese food' (they changed their minds), and even for a Chinese New Year celebration. There's something incredibly satisfying about creating restaurant-quality food at home, especially when it comes together this quickly. The balance of tender beef, crisp vegetables, and that intensely flavored sauce makes this a dish I never get tired of cooking or eating.
