Ingredients

Instructions

  1. Step 1: In a medium bowl, whisk together 2 tbsp gochujang, 3 tbsp soy sauce, 1 tbsp sesame oil, 1 tbsp brown sugar, 3 minced garlic cloves, and 1 tbsp minced fresh ginger until smooth. Add 12 oz thinly sliced sirloin steak and marinate for 15 minutes.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the marinated beef in a single layer, cooking for 2-3 minutes without stirring to develop a sear, then stir-fry for another 2 minutes until beef is cooked through but still tender.
  3. Step 3: Add 1 medium julienned carrot and 1 sliced red bell pepper to the beef, stir-frying together for 3-4 minutes until vegetables are crisp-tender.
  4. Step 4: Stir in 3 sliced green onions and cook for another 30 seconds. Remove from heat and sprinkle 1 tbsp toasted sesame seeds on top before serving immediately with steamed rice or noodles.
