In a medium bowl, whisk together the brown sugar, soy sauce, minced garlic, grated ginger, olive oil, and apple cider vinegar until the sugar is dissolved and the mixture is well-combined.
Season the chicken thighs with salt and pepper, then place them in a resealable plastic bag or shallow dish.
Pour the marinade over the chicken, ensuring each piece is well-coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes (or up to overnight for deeper flavor).
Preheat your oven to 375°F (190°C).
Heat a large oven-safe skillet over medium-high heat. Remove the chicken from the marinade (keep the marinade for later) and sear the chicken thighs in the skillet for 3-4 minutes on each side, until they have a golden-brown crust.
Once seared, pour the reserved marinade over the chicken in the skillet.
Transfer the skillet to the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
Remove the skillet from the oven and let the chicken rest for a few minutes before slicing.
To serve, drizzle some of the pan sauce over the chicken and garnish with sliced green onions.
Notes
Serve with steamed jasmine rice and sautéed vegetables for a complete meal.
