01 - Preheat oven to 400°F. Position the rack in the center.
02 - Pat chicken thighs dry with paper towels and season both sides lightly with salt and pepper.
03 - In a small mixing bowl, whisk together apricot preserves, soy sauce, Dijon mustard, rice vinegar, honey, minced garlic, grated ginger, and crushed red pepper flakes until smooth and well combined.
04 - Heat vegetable oil in a large ovenproof skillet over medium-high heat. Add chicken thighs in a single layer and sear for 3 to 4 minutes per side until a golden crust forms.
05 - Pour the apricot glaze over the seared chicken, turning each piece to coat evenly on all sides.
06 - Transfer the skillet to the preheated oven and bake, uncovered, for 18 to 22 minutes until the chicken is cooked through to an internal temperature of 165°F and the sauce is bubbling, thick, and sticky.
07 - Remove the skillet from the oven and let the chicken rest for 2 to 3 minutes so the sauce settles and thickens slightly.
08 - Sprinkle sliced green onions and sesame seeds over the chicken. Serve immediately with steamed rice or sautéed greens.
