01 - Preheat your oven to 400°F.
02 - Thoroughly pat dry the chicken thighs with absorbent paper towels. Season both sides generously with salt and freshly ground black pepper.
03 - Heat olive oil in a large, oven-safe skillet over medium-high heat. Place the chicken thighs skin-side down and sear for 3-4 minutes until a rich golden-brown crust forms. Flip and sear the second side for 2 minutes. Carefully remove any excess rendered fat from the skillet.
04 - In a separate small mixing bowl, vigorously whisk together the honey, low-sodium soy sauce, minced garlic, apple cider vinegar, grated ginger, and crushed red pepper flakes.
05 - Pour the prepared honey garlic sauce evenly over the chicken thighs within the skillet. Ensure each piece is well-coated by spooning some sauce over the top.
06 - Transfer the skillet to the preheated oven. Bake for 20-25 minutes, basting the chicken with the sauce once during the midpoint of the cooking time. Continue cooking until the chicken is thoroughly cooked (internal temperature reaches 175°F) and the sauce has reduced to a thick, glistening glaze.
07 - Remove the skillet from the oven and allow the chicken to rest for 5 minutes. Spoon any accumulated extra sauce over the chicken. Garnish with chopped fresh parsley or green onions and optional sesame seeds before serving.
