Ingredients

• 12 oz, thinly sliced against the grain flank steak
• 3 cups broccoli florets
• 5 cloves, thinly sliced garlic cloves
• 1 tbsp, grated fresh ginger
• 3 tbsp soy sauce
• 2 tbsp oyster sauce
• 1 tsp sesame oil
• 1 tbsp cornstarch
• 1/4 cup water
• 2 tbsp vegetable oil
• 1 tsp brown sugar
• 1/4 tsp, optional red pepper flakes
• 2, sliced for garnish green onions

Instructions

1. Step 1: Toss 12 oz thinly sliced flank steak with 1 tbsp cornstarch in a medium bowl until evenly coated.
2. Step 2: In a small bowl, whisk 3 tbsp soy sauce, 2 tbsp oyster sauce, 1/4 cup water, 1 tsp brown sugar, 1 tsp grated fresh ginger, and 1/4 tsp red pepper flakes (optional). Set sauce aside.
3. Step 3: Heat 2 tbsp vegetable oil in a large skillet or wok over high heat until shimmering. Add half of the beef in a single layer and sear for 1-2 minutes without stirring until browned on one side, then stir and cook for another 1 minute until just cooked through. Remove to a plate and repeat with remaining beef.
4. Step 4: In the same skillet, add 3 cups broccoli florets and 5 thinly sliced garlic cloves. Stir-fry for 3-4 minutes until broccoli is bright green and tender-crisp, garlic is fragrant.
5. Step 5: Return beef to the pan and pour in the prepared sauce. Stir everything together and cook for 1-2 minutes until sauce thickens and coats the beef and broccoli evenly.
6. Step 6: Drizzle 1 tsp sesame oil over the stir-fry, toss gently, then garnish with 2 sliced green onions before serving immediately over steamed rice if desired.
