Ready to dive in? Let’s get cooking! Here’s how to create this delicious stir fry that will have your family asking for seconds:

1. Begin by marinating the beef. In a bowl, combine the sliced beef with soy sauce, oyster sauce, and corn starch. Let it sit for about 10 minutes while you prepare the other ingredients. This step not only enhances the flavor but also tenderizes the meat.
2. Heat a large skillet or wok over medium-high heat and add 1 tablespoon of vegetable oil. Once hot, add the marinated beef in a single layer. Sear it for about 2-3 minutes until browned, then flip and cook for another 2 minutes. Remove the beef from the skillet and set it aside.
3. In the same skillet, add the remaining tablespoon of oil. Toss in the sliced onions and stir-fry for about 3-4 minutes until they become translucent and slightly caramelized. The sweetness of the onions is a beautiful contrast to the savory beef.
4. Add the minced garlic and ginger to the onions, stirring constantly for about 30 seconds until fragrant. This is when your kitchen will start to smell amazing!
5. Return the beef to the skillet, mixing it well with the onions. Season with salt and pepper to your liking. Stir everything together for another 2-3 minutes to ensure it’s heated through and well combined.
6. Once everything is cooked to perfection, serve your stir fry immediately over steamed rice or noodles. The glossy sauce should coat each piece beautifully, making it irresistible!
