Creating Chicken Bulgogi can be straightforward if you follow these simple steps:

1. Prepare the Chicken: Thinly slice the boneless chicken thighs into bite-sized pieces and set aside.
2. Make the Marinade: In a mixing bowl, combine soy sauce, brown sugar, sesame oil, minced garlic, grated ginger, gochujang (if using), and rice wine. Mix well until sugar is dissolved.
3. Marinate the Chicken: Add the sliced chicken to the marinade. Ensure all pieces are well-coated. Cover the bowl and let it marinate in the refrigerator for at least 20 minutes.
4. Heat the Pan: In a large skillet or grill pan, heat the vegetable oil over medium-high heat.
5. Cook the Chicken: Once the oil is hot, add the marinated chicken to the pan in a single layer. Cook for about 5-7 minutes until the chicken is browned and cooked through, stirring occasionally.
6. Add Green Onions: In the last minute of cooking, add the chopped green onions to the pan and stir to combine.
7. Garnish: Remove from heat and sprinkle sesame seeds over the cooked chicken for added flavor and crunch.
8. Rest: Allow the chicken to rest for about 5 minutes before serving.
