Equipment

  • wok or large pan
  • mixing bowl
  • knife and cutting board
  • spatula or wooden spoon
  • Measuring spoons

Ingredients
  

  • 1 lb beef tenderloin, diced into bite-size cubes
  • 1 tbsp cooking wine or dry sherry
  • 1 tbsp light soy sauce
  • 1 tbsp dark soy sauce
  • 1 tbsp oyster sauce
  • Pinch black pepper
  • 3 tsp cooking oil, divided
  • 1/2 small pineapple (~150 g), diced
  • 1 bell pepper, sliced (optional)
  • 1 small onion, sliced (optional)
  • 1/2 cup snap peas or green beans (optional)
  • 2 tbsp soy sauce (for sauce)
  • 1 tbsp rice vinegar
  • 1 tbsp brown sugar or honey
  • 1 tsp cornstarch mixed with 2 tbsp water

Instructions
 

  • Combine beef cubes with cooking wine, light and dark soy sauces, oyster sauce, and a pinch of black pepper. Drizzle 1 tsp oil, toss to coat, and let rest for 20 minutes.
  • Dice the pineapple into bite-size pieces. Optional: soak in lightly salted water for 10 minutes, then drain and pat dry.
  • Heat 1 tsp oil in a wok or large pan over medium-high heat. Sauté pineapple until it starts releasing juice, about 3–4 minutes, then remove from the pan. Lightly stir-fry vegetables, if using.
  • Add 2 tsp oil to the pan and increase heat to high. Add marinated beef cubes and sear until browned on all sides, about 4–5 minutes. Work in batches if needed.
  • Return pineapple (and vegetables) to the pan. Pour in sauce mixture if desired. Stir and cook 2–3 minutes until sauce thickens slightly.
  • Serve immediately over steamed rice or noodles. Garnish with green onions or sesame seeds if desired.

Notes

Marinate beef ahead for extra tenderness. Customize with your favorite vegetables or protein swaps. Adjust sauce sweetness and acidity to taste. Keeps well in the fridge for 2–3 days and can be frozen for up to 1 month.
