01 - Preheat oven to 400°F.
02 - Pat chicken thighs dry with paper towels and season lightly with salt and pepper on both sides.
03 - In a small mixing bowl, whisk together the 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 and sear for 3 to 4 minutes per side until a golden crust forms.
05 - Pour the apricot glaze over the seared chicken, tossing to coat each piece evenly.
06 - Transfer the skillet to the 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 and sticky.
07 - Remove the skillet from the oven and let the chicken rest for 2 to 3 minutes to allow the sauce to thicken slightly.
08 - Garnish with sliced green onions and sesame seeds before serving.
