Ingredients
- 1 pound beef steak (such as sirloin, flank, or ribeye), thinly sliced against the grain
- 2 tablespoons soy sauce
- 1 tablespoon oyster sauce
- 1 teaspoon cornstarch
- 2 tablespoons vegetable oil
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- 1 onion, sliced
- 2 cloves garlic, minced
- 1 teaspoon ginger, grated
- ¼ cup beef broth or water
- Salt and pepper to taste
Instructions
Step 1: Marinate the Beef
Marinating the beef is essential for both flavor and texture. The soy sauce and oyster sauce infuse the meat with a savory depth, while the cornstarch helps to tenderize it. Allowing the beef to sit in the marinade for at least 15 minutes ensures that each slice absorbs the flavors, but if time allows, marinating for 30 minutes will yield even better results.
Step 2: Sear the Beef
Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat. When the oil is hot, add the beef slices in a single layer. It is important not to overcrowd the pan, as this will prevent proper searing. Cook for 1 to 2 minutes on each side until browned, then remove from the skillet and set aside.
Step 3: Sauté the Vegetables
In the same skillet, add the remaining tablespoon of oil. Add the sliced bell peppers and onion. Stir-fry for 3 to 4 minutes until the vegetables are tender but still crisp. The key to achieving the perfect texture is to keep the heat high and stir frequently.
Step 4: Add Aromatics
Once the vegetables are slightly softened, add the minced garlic and grated ginger. Sauté for another minute until fragrant. This step enhances the dish with a layer of aromatic depth.
Step 5: Combine Everything
Return the seared beef to the skillet. Pour in the beef broth or water and stir well to coat all ingredients. Cook for another 2 to 3 minutes, allowing the sauce to thicken slightly. If a thicker sauce is desired, a small additional amount of cornstarch mixed with water can be added at this stage.
Step 6: Final Seasoning and Serving
Taste the dish and adjust the seasoning with salt and pepper if needed. Once everything is well combined, remove from heat and serve immediately.
Notes
- Choosing the Right Beef: Using a tender cut such as sirloin, flank, or ribeye ensures that the beef remains juicy and flavorful. Slicing against the grain shortens the muscle fibers, making the beef more tender.
- High Heat is Key: Cooking on high heat helps achieve a nice sear on the beef and prevents the vegetables from becoming soggy.
- Avoid Overcrowding the Pan: Cooking the beef in batches if necessary ensures even browning and prevents steaming.
- Adjust the Sauce to Taste: Some may prefer a more intense sauce, while others enjoy a lighter flavor. Adjust soy sauce and broth amounts according to preference.
- Thickening the Sauce: If the sauce is too thin, mix a teaspoon of cornstarch with a tablespoon of water and stir it into the skillet. Let it simmer for a minute until the sauce thickens.
- Balancing Sweetness and Saltiness: Adding a small pinch of sugar can help balance out the flavors, especially if a sweeter profile is desired.
