Creating Ground Beef Bulgogi is straightforward if you follow these steps:

1. Mix Marinade: In a large bowl, combine soy sauce, brown sugar, sesame oil, minced garlic, minced ginger, rice vinegar, gochujang, and black pepper. Whisk until well blended.
2. Add Beef: Add the ground beef to the marinade. Mix thoroughly, ensuring the beef is well coated.
3. Marinate: Cover the bowl with plastic wrap and allow it to marinate for at least 15 minutes. For deeper flavor, marinate for up to 2 hours in the refrigerator.
4. Cook Beef: Heat a large skillet over medium-high heat. Once hot, add the marinated ground beef. Cook, breaking it up with a spatula, until browned and cooked through (about 10-15 minutes).
5. Garnish: Once cooked, remove from heat and sprinkle with chopped green onions and sesame seeds for garnish.
6. Serve: Serve hot over cooked rice or in lettuce leaves for wraps.

These steps ensure that you create a flavorful dish that everyone will love!
