Step-by-Step Master Instructions

High Heat, Fast Cooking

Step 1: Marinate the Beef

Combine soy sauce, oyster sauce, cornstarch, and sesame oil.

Add sliced beef and toss well.

Let sit 15โ€“30 minutes.

This velveting technique keeps beef tender.


Step 2: Prepare the Sauce

Whisk together:

  • Soy sauce
  • Hoisin sauce
  • Black pepper
  • Cornstarch slurry

Set aside.

Have everything ready before heating pan โ€” stir-frying moves quickly.


Step 3: Stir-Fry the Vegetables

Heat 1 tablespoon oil over high heat.

Add onions and bell peppers.

Stir-fry 2โ€“3 minutes until slightly softened but still crisp.

Remove and set aside.


Step 4: Sear the Beef

Add remaining oil.

Spread beef in single layer.

Sear 1โ€“2 minutes per side.

Do not overcrowd โ€” cook in batches if necessary.

Add garlic and ginger. Stir 30 seconds.


Step 5: Combine and Finish

Return vegetables to skillet.

Pour in prepared sauce.

Stir continuously for 2โ€“3 minutes until sauce thickens and coats everything evenly.

Remove from heat immediately to avoid overcooking beef.
