Step 2: Prepare the Sauce
In a small bowl, mix soy sauce, oyster sauce, sugar, and water. Set aside.
Step 3: Stir-Fry the Beef
Heat a wok or pan on high. Add 1 tablespoon oil. Add the marinated beef. Cook for 2–3 minutes until it turns brown. Remove and set aside.

Top Tips
Slice Beef Thin
Cut against the grain. Thin slices cook faster and stay tender.
Use High Heat
Stir-frying needs strong heat. It helps seal flavor and keeps veggies crisp.
Don’t Overcook Peppers
Green peppers should stay a little crunchy. Soft peppers lose their taste and color.
Variations
Add More Veggies
Carrots, red peppers, or mushrooms go well with this dish.
Try Different Meats
Use chicken or pork instead of beef. Keep the same steps.
Make It Spicy
Add chili flakes or sliced fresh chili for a little heat.
