  • Total Time: Approximately 1 hour

Ingredients

Beef Marinade

  • 1 lb (450 g) flank steak or top sirloin, thinly sliced against the grain
  • 2 tablespoons low-sodium soy sauce
  • 1 tablespoon cornstarch
  • 1 teaspoon baking soda
  • 1 teaspoon vegetable oil

Stir-Fry Sauce

  • ¼ cup low-sodium soy sauce
  • 2 tablespoons oyster sauce
  • 2 tablespoons brown sugar
  • 1 tablespoon rice vinegar
  • 1 teaspoon sesame oil
  • ½ cup beef broth or water
  • 1 teaspoon cornstarch (optional, for thicker sauce)

Vegetables

  • 1 green bell pepper, cut into 1-inch chunks
  • 1 red bell pepper, cut into 1-inch chunks
  • 1 yellow or orange bell pepper, cut into 1-inch chunks

  • 2 cloves garlic, minced
  • 1 teaspoon fresh ginger, grated

For Cooking

Why Use Baking Soda?

Baking soda raises the pH on the surface of the meat, preventing proteins from tightening too quickly during cooking. This technique, called “velveting,” is commonly used in Chinese restaurants.


Equipment Needed

  • Sharp knife
  • Cutting board
  • Mixing bowls
  • Measuring cups and spoons
  • Large wok or skillet
  • Wooden spoon or spatula

Step-by-Step Instructions

Step 1: Slice the Beef

Place the steak in the freezer for 15 minutes.

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

Slice:

  • Against the grain
  • About ⅛ inch thick

Thin slices cook quickly and stay tender.


Step 2: Marinate the Beef

In a bowl combine:

  • Beef slices
  • 2 tbsp soy sauce
  • 1 tbsp cornstarch
  • 1 tsp baking soda
  • 1 tsp vegetable oil

Mix thoroughly.

Let marinate:

  • Minimum: 20 minutes
  • Best: 30 minutes

Step 3: Prepare the Sauce

Whisk together:

  • ¼ cup soy sauce
  • 2 tbsp oyster sauce
  • 2 tbsp brown sugar
  • 1 tbsp rice vinegar
  • 1 tsp sesame oil
  • ½ cup beef broth

For a thicker sauce:

  • Add 1 tsp cornstarch

Set aside.


Step 4: Cook the Vegetables

Heat 1 tbsp oil in a wok over high heat.

Add:

  • Bell peppers
  • Onion

Cook:

  • 3–4 minutes
  • Stir frequently

Vegetables should remain slightly crisp.

Remove and set aside.


Step 5: Cook the Beef

Add remaining oil.

Spread beef into a single layer.

Cook:

  • 1 minute undisturbed
  • Stir and cook another 2 minutes

Add:

  • Garlic
  • Ginger

Cook 30 seconds.


Step 6: Combine Everything

Return vegetables to the pan.

Pour in sauce.

Stir continuously.

Cook:

  • 1–2 minutes

Sauce should coat all ingredients evenly.


Step 7: Serve

Serve over:

  • Steamed white rice
  • Brown rice
  • Jasmine rice
  • Cauliflower rice
  • Noodles

Garnish with:

  • Green onions
  • Sesame seeds
