Ingredients

For the Beef:

1 lb (450g) flank steak or sirloin, thinly sliced against the grain
1 tablespoon soy sauce
1 tablespoon cornstarch
1 teaspoon sesame oil
½ teaspoon black pepper

For the Vegetables:

1 large green bell pepper, thinly sliced
1 large red bell pepper, thinly sliced
1 large onion, thinly sliced
2–3 cloves garlic, minced

For the Sauce:

½ cup beef broth
2 tablespoons soy sauce
1 tablespoon oyster sauce (optional but recommended)
1 tablespoon hoisin sauce (optional)
1 teaspoon cornstarch
1 teaspoon sugar
½ teaspoon black pepper
½ teaspoon crushed red pepper flakes (optional for heat)
2 tablespoons vegetable oil (for stir-frying)

Step-by-Step Instructions

1. Prepare the Beef

In a medium bowl, combine sliced beef, soy sauce, cornstarch, sesame oil, and black pepper.
Toss to coat evenly and set aside for 10–15 minutes to marinate.

2. Mix the Sauce

In a small bowl, whisk together beef broth, soy sauce, oyster sauce, hoisin sauce, cornstarch, sugar, black pepper, and red pepper flakes.
Set aside. This will thicken quickly once added to the stir-fry.

3. Stir-Fry the Beef

Heat 1 tablespoon vegetable oil in a wok or large skillet over high heat.
Add beef in a single layer and sear for 2–3 minutes until browned but not fully cooked.
Remove beef and set aside.

4. Stir-Fry the Vegetables

Add remaining oil to the wok.
Add sliced onions and bell peppers. Stir-fry for 3–4 minutes until crisp-tender.
Add garlic and cook 30 seconds more until fragrant.

5. Combine Beef and Sauce

Return the beef to the pan.
Pour in the prepared sauce and stir to coat everything evenly.
Cook for 2–3 minutes, allowing the sauce to thicken and the beef to finish cooking.

6. Serve Hot

Serve immediately over steamed white rice, brown rice, or fried rice.
Garnish with sliced green onions or sesame seeds if desired.

Tips for Perfect Chinese Pepper Steak

Slice beef thinly against the grain: Ensures tenderness.
High heat cooking: Keeps vegetables crisp and beef juicy.
Don’t overcrowd the pan: Stir-fry in batches if needed.
Marinate the beef: Adds flavor and keeps meat tender.
Cornstarch slurry in sauce: Helps thicken quickly and coat ingredients beautifully.

Variations

Spicy Pepper Steak

Add 1–2 chopped fresh chilies or increase red pepper flakes.

Mushroom Pepper Steak

Low-Sodium Version

Use low-sodium soy sauce and skip oyster sauce.

Sweet Pepper Steak

Add 1 teaspoon honey or a splash of hoisin sauce to the sauce for a sweeter taste.

Spoon over fried rice for a hearty meal
Pair with steamed broccoli or bok choy for extra vegetables

Storage & Reheating

Refrigeration: Store leftovers in an airtight container for up to 3 days.
Reheating: Warm gently in a skillet over medium heat or microwave in short intervals. Avoid overcooking to keep beef tender.
