Ingredients

• 1 lb beef sirloin, thinly sliced
• 1 large onion, sliced
• 2 tbsp oyster sauce
• 2 tbsp soy sauce
• 1 tbsp hoisin sauce
• 1 tbsp cornstarch
• 2 tbsp vegetable oil
• 2 cloves garlic, minced
• 1/2 tsp sweetener (or sugar)
• 1/2 cup water or beef broth
• 2 green onions, chopped (for garnish)

Instructions

1. Marinate the beef: In a bowl, mix the sliced beef with 1 tbsp soy sauce and 1 tbsp cornstarch. Let it rest 15 minutes.
2. Prepare the sauce: In another bowl, combine oyster sauce, remaining soy sauce, hoisin sauce, sweetener, and water or broth. Stir and set aside.
3. Cook the beef: Heat 1 tbsp oil in a large skillet or wok over high heat. Stir-fry beef until just browned (2–3 minutes). Remove and set aside.
4. Cook the onions: Add remaining oil, then onions. Stir-fry 3–4 minutes until slightly softened. Add minced garlic and cook another 1 minute.
5. Combine: Return beef to the pan. Pour in sauce mixture and toss everything together for 2–3 minutes until sauce thickens and coats the beef. Garnish with chopped green onions and serve hot with rice.
