Ingredients

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, and 1 tbsp vegetable oil until well combined.
  2. Step 2: Add 1 lb thinly sliced beef sirloin to the bowl and toss to coat evenly. Let marinate for 10 minutes while you prepare the spinach.
  3. Step 3: Heat 2 tbsp sesame oil in a large skillet over medium-high heat. Add 6 cups fresh spinach leaves and sauté for 2-3 minutes until wilted. Remove spinach and set aside.
  4. Step 4: In the same skillet, add the marinated beef in a single layer. Cook for 3-4 minutes, stirring occasionally, until beef is browned and sauce thickens.
  5. Step 5: Return the spinach to the skillet and toss with the beef for 1 minute until heated through. Sprinkle with 1 tbsp toasted sesame seeds and 2 sliced green onions before serving.
