Ingredients

(Serves 3–4)

• 1 pound (450g) beef (such as flank steak or sirloin), thinly sliced against the grain
• 1 large onion , sliced into thin strips
• 2 cloves garlic , minced
• 2 tablespoons soy sauce
• 1 tablespoon oyster sauce (optional, for added depth of flavor)
• 1 tablespoon cornstarch
• 2 tablespoons vegetable oil (for cooking)
• Salt and pepper to taste
• Optional: Sliced green onions for garnish

Instructions

Step 1: Prepare the Beef

1. Thinly slice the beef against the grain to ensure tenderness.
2. In a bowl, combine the sliced beef with 1 tablespoon soy sauce , 1 tablespoon cornstarch , and a pinch of pepper. Mix well to coat the beef evenly. Let it marinate for 10–15 minutes while you prepare the other ingredients.

Step 2: Cook the Beef

1. Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat.
2. Add the marinated beef in a single layer and sear for 1–2 minutes per side, just until browned but not fully cooked through. Remove the beef from the pan and set aside.

Step 3: Cook the Onions and Garlic

1. In the same skillet, add the remaining 1 tablespoon of vegetable oil .
2. Add the sliced onions and cook for 3–4 minutes, stirring occasionally, until they begin to soften and caramelize slightly.
3. Stir in the minced garlic and cook for an additional 30 seconds, until fragrant.

Step 4: Combine and Finish the Dish

1. Return the cooked beef to the skillet with the onions and garlic.
2. Add the remaining 1 tablespoon soy sauce and oyster sauce (if using). Stir everything together and cook for 1–2 minutes, until the beef is fully cooked and the flavors are well combined.
3. Taste and adjust seasoning with salt and pepper if needed.

Step 5: Serve and Garnish

1. Transfer the stir fry to a serving plate or bowl.
2. Garnish with sliced green onions for a pop of color and freshness, if desired.
3. Serve hot with steamed rice, fried rice, or noodles for a complete meal.

Tips for Success

• Slice Thinly: Use a sharp knife or partially freeze the beef for 20–30 minutes to make slicing easier.
• High Heat is Key: Stir-frying requires high heat to achieve tender beef and caramelized onions. Avoid overcrowding the pan to ensure proper browning.
• Customize Vegetables: Add other vegetables like bell peppers, broccoli, or snap peas for extra flavor and nutrition.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet or microwave, adding a splash of water or broth to prevent drying out.
