Ingredients

For the Beef

1½ lb (700 g) flank steak or sirloin
2 tablespoons soy sauce
1 tablespoon cornstarch
1 tablespoon Shaoxing wine or dry sherry
1 teaspoon sesame oil
1 teaspoon sugar
½ teaspoon black pepper
1 tablespoon vegetable oil

For the Stir-Fry

1 large green bell pepper, sliced
1 large red bell pepper, sliced
1 large yellow onion, sliced into wedges
3 cloves garlic, minced
1 teaspoon fresh ginger, grated
2 tablespoons vegetable oil

For the Sauce

¼ cup soy sauce
2 tablespoons oyster sauce
1 tablespoon hoisin sauce
1 tablespoon Shaoxing wine or dry sherry
1 teaspoon sugar
½ cup beef broth
1 teaspoon sesame oil
1 tablespoon cornstarch
2 tablespoons cold water

For Garnishing

Sliced green onions
Sesame seeds
Freshly cracked black pepper
Red pepper flakes, optional

Directions

1. Slice the Beef

Place the steak in the freezer for approximately 15–20 minutes.

This firms the meat slightly and makes it much easier to slice thinly.

Slice the beef against the grain into thin strips.

Why slice against the grain?

Muscle fibers run in a particular direction. Cutting across them shortens the fibers, producing much more tender bites.

2. Marinate the Beef

Place the sliced beef in a bowl.

Add:

Soy sauce
Cornstarch
Shaoxing wine
Sesame oil
Sugar
Black pepper

Mix thoroughly until every piece is coated.

Let the beef marinate for 15–30 minutes.

The cornstarch helps create a tender texture and gives the beef lightly crisp edges when stir-fried.

3. Prepare the Sauce

In a small bowl, whisk together:

Soy sauce
Oyster sauce
Hoisin sauce
Shaoxing wine
Sugar
Beef broth
Sesame oil

In a separate small bowl, mix the cornstarch with cold water to make a slurry.

Set both aside.

4. Heat the Wok

Place a wok or large skillet over high heat.

Let it become very hot before adding the oil.

Add 1 tablespoon vegetable oil.

5. Sear the Beef

Add the beef in a single layer.

Don’t overcrowd the wok.

Cook for approximately 1–2 minutes per side, tossing occasionally, until browned around the edges.

Transfer the beef to a clean plate.

Important:

The beef doesn’t need to be completely cooked at this stage. It will finish cooking when returned to the wok later.

Cook in batches if necessary.

6. Stir-Fry the Vegetables

Add the remaining tablespoon of oil.

Add the onions and bell peppers.

Stir-fry over high heat for approximately 3–4 minutes.

The vegetables should become slightly tender while retaining some crispness.

Add the minced garlic and grated ginger.

Stir-fry for another 30–45 seconds.

Don’t let the garlic burn.

7. Add the Sauce

Pour the prepared sauce into the hot wok.

Bring it to a gentle simmer.

Stir the cornstarch slurry once more and slowly pour it into the sauce while stirring.

Cook for approximately 1–2 minutes, until the sauce becomes glossy and slightly thickened.

8. Return the Beef

Add the seared beef back to the wok.

Toss everything together until the beef and vegetables are coated in the sauce.

Cook for another 1–2 minutes, just until the beef is cooked through.

Don’t overcook it.

9. Make It Sizzle

For the classic restaurant-style presentation, heat a cast-iron skillet or sizzling serving plate until very hot.

Carefully transfer the finished pepper steak onto the hot surface.

You should hear an immediate sizzle.

Drizzle a little extra sauce over the top.

Garnish with sliced green onions and sesame seeds.

Be extremely careful when handling the hot skillet or serving plate.

10. Serve

Serve immediately with:

Steamed white rice
Fried rice
Chow mein
Lo mein
Egg noodles

For extra heat, sprinkle with red pepper flakes or serve with chili sauce.

Tips for the Best Pepper Steak

Choose the Right Beef

Flank steak, sirloin, or top round work well. The most important thing is slicing the meat thinly against the grain.

Get Restaurant-Style Flavor

Use Shaoxing wine if available. It adds a characteristic savory depth to Chinese stir-fry dishes.

Keep the Vegetables Crisp

Don’t cook the peppers and onions until completely soft. A little crunch gives the dish better texture.
