Directions1.
Preheat your oven to 400°F / 200°C. 2.
Brush 1 tablespoon (15 ml / 0.5 fl oz) of the sesame oil over both sides of the chicken thighs.
In a small bowl, combine the Chinese five-spice powder, garlic powder, and salt. 3.
Season the chicken thighs generously on both sides with the spice mixture, pressing it firmly into the skin to help it adhere. 4.
In a separate mixing bowl, whisk together the soy sauce, vinegar, lime juice, minced garlic, grated ginger, and red pepper flakes.
Set this sauce mixture aside. 5.
Heat the remaining 1 tablespoon (15 ml / 0.5 fl oz) of sesame oil in a large, oven-safe skillet over medium-high heat. Carefully place the chicken thighs skin-side down and sear for 5 to 6 minutes, until the skin is deeply golden-brown and crispy.
Flip the chicken and transfer the entire skillet to the preheated oven. 6.
Bake for 15 to 20 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F / 74°C.
Remove the chicken from the pan and set it on a plate, covering it loosely to keep warm. 7. Carefully return the skillet to the stovetop over medium heat.
Pour in the soy sauce mixture, using a spatula to scrape up any flavorful browned bits from the bottom of the pan.
Bring the sauce to a boil, then reduce the heat to low.
Simmer until the sauce has thickened and reduced by about half. 8. Return the chicken thighs to the pan, spooning the glaze over them to coat. Plate the chicken, pour the remaining sauce over the top, and garnish with sliced green onions, toasted sesame seeds, and an extra pinch of red pepper flakes before serving.
Don't walk away from the sauce while it's reducing! It can go from perfectly thickened to overly syrupy very quickly. Watch it closely and pull it from the heat as soon as it coats the back of a spoon.
