Ingredients

• 1 lb, thinly sliced against the grain flank steak
• 3 tbsp soy sauce
• 2 tbsp brown sugar
• 1 tbsp sesame oil
• 3 cloves, minced garlic cloves
• 1 tbsp, grated fresh ginger
• 2 tbsp vegetable oil
• 4 stalks, thinly sliced scallions
• 1 tbsp toasted sesame seeds
• 1/4 tsp (optional) crushed red pepper flakes

Instructions

1. Step 1: In a medium bowl, whisk together 3 tbsp soy sauce, 2 tbsp brown sugar, 1 tbsp sesame oil, 3 minced garlic cloves, and 1 tbsp grated fresh ginger. Add 1 lb thinly sliced flank steak and marinate for 15 minutes.
2. Step 2: Heat 2 tbsp vegetable oil in a large skillet or wok over high heat until shimmering. Remove steak from marinade, reserving the liquid, and stir-fry the beef strips for 3-4 minutes until browned and just cooked through.
3. Step 3: Pour the reserved marinade into the skillet and cook for 1-2 minutes until the sauce thickens and coats the beef. Stir in 4 thinly sliced scallions, 1 tbsp toasted sesame seeds, and 1/4 tsp crushed red pepper flakes if using. Serve immediately over steamed rice or noodles.
