Instructions

  1. Step 1: In a large bowl, whisk together 1/4 cup soy sauce, 2 tbsp brown sugar, 3 cloves minced garlic, 1/4 cup grated pear, 2 tsp sesame oil, and 1/4 tsp ground black pepper to create the marinade.
  2. Step 2: Add 1 lb thinly sliced beef sirloin to the marinade, tossing to coat evenly; cover and refrigerate for at least 30 minutes.
  3. Step 3: Heat 1 tbsp vegetable oil in a large skillet over medium heat. Add 1 large thinly sliced yellow onion and cook for 8-10 minutes, stirring occasionally, until the onions are deeply caramelized.
  4. Step 4: Increase the heat to medium-high and add the marinated beef along with any leftover marinade; stir-fry for 4-5 minutes until the beef is cooked through and slightly caramelized.
  5. Step 5: Remove from heat and garnish with 2 tbsp sliced green onions and 1 tbsp toasted sesame seeds before serving.
