In a mixing bowl, whisk together the honey, minced garlic, soy sauce, apple cider vinegar, grated ginger, and a pinch of salt and pepper until well combined. Place the chicken thighs into a resealable plastic bag or shallow dish, then pour the marinade over them, ensuring the thighs are well coated. Seal the bag or cover the dish, and refrigerate for at least 30 minutes; for the best flavor, marinate for up to 3 hours.
While the chicken is marinating, preheat your oven to 400°F (200°C) to ensure it's hot and ready to bake.
In a large, oven-safe skillet, heat the olive oil over medium-high heat. Carefully remove the chicken thighs from the marinade, setting the marinade aside for later use. Place the thighs, skin-side down, into the hot skillet, and sear them for about 4 minutes until the skin is beautifully golden and crispy. Flip the thighs and sear for an additional 2 minutes on the other side for added flavor.
Pour the reserved marinade over the chicken thighs in the skillet, coating them evenly. Then, transfer the skillet to your preheated oven. Bake for 25-30 minutes or until the chicken is fully cooked and juices run clear, reaching an internal temperature of 165°F (75°C). To enhance the flavor and ensure moisture, baste the chicken with the sauce halfway through the cooking time.
Once cooked, carefully remove the skillet from the oven and allow the chicken to rest for 5 minutes to retain its juices. Just before serving, sprinkle sesame seeds and the finely sliced green onions over the chicken for a vibrant and flavorful touch.
Notes
For best flavor, marinate the chicken for up to 3 hours.
