Ingredients
Main Ingredients
- 400g beef sirloin, thinly sliced
- 2 large onions, sliced
- 3 cloves garlic, minced
- 1 teaspoon fresh ginger, grated
- 2 green onions, chopped (for garnish)
Sauce and Seasoning
- 2 tablespoons soy sauce
- 1 tablespoon oyster sauce
- 1 teaspoon sugar
- 1/2 teaspoon black pepper
- 2 tablespoons water
- 1 teaspoon sesame oil
Thickening and Cooking
- 1 tablespoon cornstarch
- 2 tablespoons vegetable oil
Choosing the Right Ingredients
Beef Selection
The quality of your beef plays a major role in the final dish. Sirloin is an excellent choice because it strikes a balance between tenderness and flavor. It is lean enough to cook quickly but still has enough marbling to remain juicy.
For best results:
- Slice the beef thinly against the grain. This shortens the muscle fibers and ensures tenderness.
- Slightly freeze the beef for about 15–20 minutes before slicing to make cutting easier.
If sirloin is not available, flank steak or ribeye can also be used. Each brings a slightly different texture and richness, but all work beautifully in this recipe.
Onions
Onions are more than just a supporting ingredient here—they are a star. As they cook, they release natural sugars and develop a soft, caramelized flavor that enhances the entire dish.
Yellow onions are ideal for their balance of sweetness and sharpness, but white or even red onions can be used depending on your preference.
Aromatics
Garlic and ginger are essential in stir-fry cooking. Garlic adds depth and richness, while ginger provides a subtle heat and freshness that keeps the dish from feeling heavy.
Always use fresh garlic and ginger if possible. The flavor difference is noticeable and worth the extra effort.
Preparation Steps
Step 1: Slice and Marinate the Beef
Place the thinly sliced beef in a bowl. Add:
- 1 tablespoon soy sauce
- 1 teaspoon cornstarch
Mix well until the beef is evenly coated. Let it marinate for at least 15–20 minutes. This step not only adds flavor but also helps tenderize the meat and create a silky texture when cooked.
Step 2: Prepare the Sauce
In a small bowl, combine:
- Remaining soy sauce
- Oyster sauce
- Sugar
- Black pepper
- Water
Mix until smooth and set aside. Having the sauce ready in advance is key, as stir-frying moves quickly.
Step 3: Prepare the Vegetables
Slice the onions into even strips and chop the green onions. Mince the garlic and grate the ginger. Keep everything within reach, as timing is crucial once you start cooking.
Cooking Instructions
Step 1: Heat the Pan
Heat a large skillet or wok over medium-high heat. Add 1 tablespoon of vegetable oil and allow it to heat until shimmering.
Step 2: Cook the Beef
Add the marinated beef in a single layer. Let it sear undisturbed for about 1–2 minutes to develop a golden crust. Then stir-fry until just cooked through. Remove the beef from the pan and set aside.
Avoid overcrowding the pan, as this can cause the beef to steam instead of sear. If necessary, cook in batches.
Step 3: Sauté the Aromatics
Add the remaining tablespoon of oil to the pan. Toss in the garlic and ginger, stirring quickly for about 30 seconds until fragrant.
Step 4: Cook the Onions
Add the sliced onions and stir-fry for 3–5 minutes. They should become soft and slightly caramelized while still retaining some texture.
Step 5: Combine and Sauce
Return the cooked beef to the pan. Pour in the prepared sauce and stir everything together. Allow the sauce to simmer for 2–3 minutes, thickening slightly and coating the beef and onions.
Step 6: Finish with Sesame Oil
Turn off the heat and drizzle the sesame oil over the stir-fry. Toss gently to combine.
Step 7: Garnish and Serve
Sprinkle chopped green onions over the top and serve immediately.
Cooking Tips for Success
High Heat is Essential
Stir-frying relies on high heat to quickly cook ingredients while preserving their texture and flavor. Make sure your pan is hot before adding anything.
Prep Everything in Advance
Once you start cooking, the process moves quickly. Having all ingredients prepped and ready ensures a smooth experience.
Don’t Overcook the Beef
Beef can become tough if overcooked. Remove it from the pan as soon as it is just done, then return it later to finish cooking in the sauce.
Balance the Sauce
Taste the sauce before adding it to the pan. Adjust with a little more sugar, soy sauce, or water depending on your preference.
Serving Suggestions
This dish is incredibly versatile and can be served in a variety of ways:
- Over steamed white rice for a classic meal
- With brown rice for a healthier option
- Alongside noodles for a hearty variation
- Wrapped in lettuce leaves for a low-carb option
- Paired with stir-fried vegetables like broccoli or bell peppers
For a complete meal, consider adding a light soup or a simple cucumber salad on the side.
Variations

Add chili flakes or sliced fresh chili peppers for a spicy kick.
Vegetable Boost
Incorporate vegetables such as bell peppers, snap peas, or mushrooms to add color and nutrition.
Low-Sodium Option
Use low-sodium soy sauce and reduce the oyster sauce slightly to control salt levels.
Gluten-Free Version
Substitute soy sauce with tamari or a gluten-free soy alternative, and ensure the oyster sauce is gluten-free.
Storage and Reheating
Storage
Allow the stir-fry to cool completely before transferring it to an airtight container. Store in the refrigerator for up to 3 days.
Reheating
Reheat in a skillet over medium heat until warmed through. Add a splash of water if needed to loosen the sauce. Avoid microwaving for too long, as it can make the beef tough.
