Mix soy sauce, brown sugar, minced garlic, bourbon, apple cider vinegar, ground ginger, and red pepper flakes in a small bowl.
Place chicken in a zip-top bag and add half of the marinade. Seal and massage to coat evenly. Refrigerate for at least 30 minutes, up to two hours. Save the remaining marinade.
Preheat a skillet over medium-high heat. Cook marinated chicken for 6-8 minutes per side until fully cooked and browned.
In a saucepan, simmer the remaining marinade for about 10 minutes until it thickens into a glaze.
Allow cooked chicken to rest for 5 minutes before slicing.
Serve chicken over steamed rice. Drizzle with the glaze. Garnish with green onions, sesame seeds, or desired toppings.
