Ingredients

For the Beef

• 1½ lb flank steak, sirloin, or skirt steak, thinly sliced against the grain
• 2 tablespoons soy sauce
• 1 tablespoon cornstarch
• 1 tablespoon vegetable or canola oil

For the Stir-Fry

• 1 medium yellow or white onion, sliced
• 1 green bell pepper, sliced
• 1 red bell pepper, sliced
• 3 cloves garlic, minced
• 1 tablespoon fresh ginger, minced
• 1–2 teaspoons freshly ground black pepper

For the Sauce

• ¼ cup soy sauce
• 1 tablespoon oyster sauce, optional
• ½ cup beef broth or water
• 1 teaspoon cornstarch
• 1 teaspoon sesame oil, optional
• 1 teaspoon brown sugar, optional

For Serving

• Steamed white rice
• Brown rice or fried rice, optional
• Noodles, optional
• Steamed vegetables, optional

Instructions

1. Slice the Beef

For the most tender results, slightly chill the beef before slicing. Cut it into thin strips against the grain.

2. Marinate the Beef

Place the sliced beef in a bowl and add the soy sauce, cornstarch, and oil. Toss well to coat and let it marinate for 15–30 minutes.

3. Prepare the Sauce

In a small bowl, whisk together the soy sauce, oyster sauce, broth or water, cornstarch, sesame oil, and brown sugar if using. Set aside.

4. Heat the Pan

Place a wok or large skillet over high heat. Allow it to become very hot before adding a little oil.

5. Cook the Beef

Add the marinated beef in a single layer. Sear quickly, stirring occasionally, until browned on the outside. Avoid overcrowding the pan.

Remove the beef and set it aside. It’s okay if it is slightly undercooked at this stage because it will finish cooking later.

6. Stir-Fry the Vegetables

Add the sliced onions and bell peppers to the hot pan. Stir-fry for 2–4 minutes, until fragrant and slightly tender while still retaining some crispness.

Add the garlic and ginger and cook for about 30 seconds, stirring constantly.

7. Combine Everything

Return the cooked beef to the pan. Give the sauce another quick stir, then pour it over the beef and vegetables.

Toss everything together for 1–2 minutes, until the sauce thickens and coats the beef and vegetables evenly.

8. Add Black Pepper

Finish with plenty of freshly ground black pepper. Taste and adjust the seasoning if needed.

9. Serve

Serve the Chinese Pepper Steak hot over steamed white rice. Garnish with additional black pepper or sliced green onions if desired.

Tips for the Best Pepper Steak

• Slice against the grain to keep the beef tender.
• Chill the beef briefly before slicing for thinner, more even pieces.
• Keep the wok or skillet very hot for the best sear.
• Cook the beef in batches if necessary to avoid steaming.
• Don’t overcook the peppers and onions—they should remain slightly crisp.
• If the sauce tastes too strong, add a splash of water or beef broth.
• For extra flavor, add a little oyster sauce or additional freshly ground black pepper.

This Chinese Pepper Steak with Onions is an easy way to enjoy a flavorful takeout-style dinner right at home.  The combination of tender beef, crisp peppers, sweet onions, and savory black pepper sauce makes every bite delicious.
