Ingredients

Instructions

  1. Step 1: In a medium bowl, whisk together 1/4 cup soy sauce, 2 tbsp brown sugar, 1 tbsp sesame oil, 3 minced garlic cloves, 1 tbsp minced fresh ginger, and 1 tbsp cornstarch until smooth. Add 1 lb thinly sliced flank steak and toss to coat. Marinate for 10 minutes.
  2. Step 2: Heat 2 tbsp vegetable oil in a large skillet or wok over high heat until shimmering. Add the marinated beef in a single layer and stir-fry for 3-4 minutes until browned and just cooked through. Remove beef and set aside.
  3. Step 3: In the same skillet, add 4 cups broccoli florets and stir-fry for 4-5 minutes until bright green and crisp-tender.
  4. Step 4: Return the beef to the skillet with broccoli. Sprinkle 1/4 tsp red chili flakes and toss everything together for 1-2 minutes until heated through and the sauce thickens slightly.
  5. Step 5: Remove from heat and garnish with 2 sliced green onions and 1 tbsp toasted sesame seeds before serving.
