  1. Marinate the Beef: In a bowl, combine the beef slices with the marinade ingredients. Mix well to ensure each piece is coated. Let it marinate for at least 30 minutes, or for better flavor, up to 2 hours in the refrigerator.
  2. Prepare the Sauce: In a separate bowl, mix together the soy sauce, oyster sauce, brown sugar, and beef broth. Set aside.
  3. Cook the Beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat. Add the marinated beef in batches, spreading it out to ensure it cooks evenly. Sear the beef until it’s just cooked through, about 1-2 minutes per side. Remove the beef from the pan and set aside.
  4. Sauté the Onions: In the same pan, add the remaining tablespoon of oil. Add the sliced onions and stir fry until they’re soft and starting to caramelize, about 5-7 minutes. Season with a pinch of salt and pepper to enhance their sweetness.
  5. Combine and Thicken the Sauce: Return the beef to the pan with the onions. Stir the sauce mixture once more, then pour it over the beef and onions. Cook, stirring, until the sauce has thickened and everything is well coated, about 2-3 minutes.
  6. Serve: Serve your Beef and Onion Stir Fry hot, garnished with sesame seeds or sliced green onions if desired. It pairs wonderfully with steamed rice or noodles.

Tips for Tender and Juicy Beef

  • Slice Against the Grain: Cutting the beef against the grain shortens the muscle fibers, making the meat more tender.
  • Marinate for Flavor and Tenderness: The combination of soy sauce, oyster sauce, and cornstarch in the marinade not only flavors the beef but also tenderizes it and helps to lock in juices.
  • High Heat for Cooking: Stir frying is a quick process that requires high heat to sear the beef and lock in flavors without overcooking it.
  • Don’t Overcrowd the Pan: Cooking the beef in batches ensures that each piece is properly seared and cooked evenly.
  • Let the Onions Caramelize: Allowing the onions to cook down and caramelize adds a natural sweetness to the dish that balances the savory elements.
