Step 1: Slice the Beef Properly

The secret to tender pepper steak starts before cooking.

Place the steak in the freezer for about 20 minutes. This firms it up and makes slicing much easier.

Slice the beef:

• Against the grain
• About ¼-inch thick
• Into bite-sized strips

This shortens the muscle fibers, making every bite incredibly tender.

---

Step 2: Marinate the Beef

Combine the sliced beef with:

• Soy sauce
• Cornstarch
• Vegetable oil

Mix until every slice is coated.

Let it marinate for 20–30 minutes.

This simple marinade helps:

• Lock in moisture
• Tenderize the meat
• Create that silky restaurant texture

---

Step 3: Prepare the Vegetables

Slice:

• Green bell pepper
• Red bell pepper
• Onion

Try to keep the slices similar in size so they cook evenly.

Mince:

• Garlic
• Fresh ginger

Having everything ready before cooking is essential because stir-frying happens quickly.

---

Step 4: Mix the Sauce

In a bowl whisk together:

• Soy sauce
• Oyster sauce
• Hoisin sauce
• Brown sugar
• Beef broth
• Rice vinegar
• Sesame oil
• Cornstarch
• Black pepper

Set aside.

The cornstarch will help thicken the sauce as it cooks.

---

Step 5: Sear the Beef

Heat a large skillet or wok over high heat.

Add a tablespoon of oil.

Cook the beef in small batches.

Avoid overcrowding the pan.

Each batch should cook for about:

• 1–2 minutes per side

You’re aiming for a nice brown crust while keeping the inside juicy.

Remove the beef and set aside.

---

Step 6: Stir-Fry the Vegetables

Add another splash of oil if needed.

Cook:

• Onion
• Bell peppers

Stir-fry for about 3–4 minutes.

The vegetables should become slightly tender while still maintaining some crunch.

Add:

• Garlic
• Ginger

Cook for another 30 seconds until fragrant.

---

Step 7: Finish the Dish

Return the beef to the skillet.

Pour in the prepared sauce.

Stir everything together.

Cook for another 2–3 minutes until the sauce thickens beautifully.

Everything should be coated in a glossy, flavorful sauce.

Top with:

• Green onions
• Sesame seeds

Serve immediately over hot rice.

Tips for Extra Tender Beef

Follow these tips:

Slice Against the Grain

Don’t Skip the Cornstarch

Cornstarch creates a protective coating that keeps the beef juicy.

Use High Heat
