Instructions

  1. Step 1: In a medium bowl, whisk together 2 tbsp gochujang, 3 tbsp soy sauce, 1 tbsp brown sugar, 3 minced garlic cloves, 1 tbsp minced fresh ginger, and 1/2 tsp black pepper until smooth.
  2. Step 2: Heat 2 tbsp vegetable oil in a large skillet or wok over high heat until shimmering. Add 1 lb thinly sliced flank steak in a single layer and stir-fry for 2-3 minutes until browned but still slightly pink inside.
  3. Step 3: Pour the gochujang sauce over the beef and stir to coat. Add 4 sliced scallions and 2 tsp sesame oil, continuing to stir-fry for another 2 minutes until the sauce thickens and clings to the beef and scallions.
