Ingredients
Scale
Beef and Vegetables
- 1 lb (450 g) beef sirloin or flank steak, thinly sliced
- 2 medium onions, thinly sliced
- 2 cloves garlic, minced
- 1 tbsp ginger, minced (optional)
- 1-2 tbsp green onions, sliced (for garnish)
Sauces and Seasonings
- 3 tbsp oyster sauce
- 1 tbsp soy sauce
- 1 tbsp hoisin sauce (optional)
- 1 tbsp rice vinegar
- 1 tsp sugar
- 1/4 tsp freshly ground black pepper
- 1/2 tsp chili flakes (optional, for heat)
Others
- 2 tbsp vegetable oil
- 2 tbsp water or beef broth (to adjust sauce consistency)
- Cooked rice, for serving
Instructions
- Prepare the beef: Slice the beef against the grain into thin strips. If the beef is too thick, place it in the freezer for about 15 minutes to firm up, making it easier to slice thinly.
- Cook the onions: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the sliced onions and stir-fry for 3-4 minutes, or until they start to soften and caramelize. Remove the onions from the pan and set them aside.
- Cook the beef: In the same pan, add the remaining 1 tablespoon of vegetable oil. Add the sliced beef and stir-fry for 2-3 minutes, or until the beef is just cooked through. Make sure the beef gets a nice sear.
- Add garlic and ginger: Add the minced garlic (and ginger, if using) to the pan and cook for 1 minute, stirring constantly until fragrant.
- Prepare the sauce: Add the oyster sauce, soy sauce, hoisin sauce (if using), rice vinegar, sugar, and black pepper to the pan. Stir well to combine, then add 2 tablespoons of water or beef broth to adjust the sauce consistency. If you like a bit of heat, sprinkle in the chili flakes.
- Combine and serve: Return the cooked onions to the pan and stir everything together, ensuring the beef is well coated with the sauce. Cook for another 1-2 minutes until everything is heated through.
- Garnish and serve: Garnish with sliced green onions and serve the stir-fry over steamed rice.
Notes
- Slice beef thinly against the grain for tenderness.
- Optional ginger adds a fresh spicy note that complements the garlic.
- Hoisin sauce can be omitted if you prefer a less sweet sauce.
- Adjust chili flakes to your desired spice level.
- Serve immediately for best texture and flavor.
- Use beef broth instead of water for a richer sauce flavor.
