Ingredients

Sauce

• 1/4 cup oyster sauce
• 2 tbsp soy sauce
• 1 tbsp dark brown sugar
• 1 tsp cornstarch
• 2 tbsp water

Beef and aromatics

• 1 lb flank steak, thinly sliced against the grain
• 2 tbsp vegetable oil
• 6 garlic cloves, minced
• 1 tsp freshly grated ginger
• 1/2 tsp flaky sea salt
• 1/4 tsp cracked black pepper
• 2 tbsp chopped fresh cilantro (optional) for garnish

Step-by-Step Instructions

1. 1. In a small bowl whisk oyster sauce, soy sauce, brown sugar, cornstarch, and water until smooth; set aside.
2. 2. Heat 1 tbsp oil in a large skillet over medium‑high heat until shimmering.
3. 3. Add minced garlic and ginger, sauté 30 seconds until fragrant but not browned.
4. 4. Add the beef in a single layer; stir‑fry 2–3 minutes, moving constantly, until just browned but still pink inside.
5. 5. Pour the prepared sauce over the beef, stir to coat, and cook 1–2 minutes until the sauce thickens and the beef is cooked through.
6. 6. Season with sea salt and cracked pepper, drizzle remaining 1 tbsp oil if needed, and garnish with cilantro before serving.

Tips for Success

• Slice the beef thinly and against the grain for maximum tenderness.
• Pat the beef dry with paper towels to achieve a good sear.
• Do not overcrowd the pan; cook in batches if necessary.
• Mix cornstarch with cold water before adding to prevent lumps.
• Adjust sweetness by adding a pinch more brown sugar if desired.

Storage

Cool the beef to room temperature, then store in an airtight container in the refrigerator for up to 3 days. Freeze in a sealed bag for up to 2 months; reheat gently in a skillet over medium heat, adding a splash of water to loosen the sauce.

Notes

Thin slicing and a hot pan are key to a tender bite. Finish with fresh herbs for bright contrast.
