Instructions

Step 1: Toss 12 oz thinly sliced flank steak with 1 tbsp cornstarch until evenly coated and set aside.
Step 2: In a small bowl, whisk together 3 tbsp soy sauce, 2 tbsp oyster sauce, 1 tbsp chili garlic sauce, 1/4 cup water, 1 tsp brown sugar, and 1 tsp sesame oil. Set sauce aside.
Step 3: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the beef slices in a single layer and stir-fry for 2-3 minutes until browned but not fully cooked. Remove beef and set aside.
Step 4: In the same wok, add 3 cups broccoli florets and stir-fry for 3 minutes until bright green and slightly tender.
Step 5: Add 5 minced garlic cloves and 1 tbsp minced ginger to the broccoli and stir-fry for 30 seconds until fragrant.
Step 6: Return beef to the wok and pour the prepared sauce over the mixture. Stir-fry everything together for 2-3 minutes until the sauce thickens and coats the beef and broccoli evenly.
Step 7: Remove from heat, garnish with 2 sliced green onions and 1 tsp toasted sesame seeds if desired. Serve immediately over steamed rice or noodles.
