Preheat your oven to 400°F (200°C).
In a bowl, whisk together the Dijon mustard, honey, olive oil, garlic powder, salt, and pepper.
Coat the chicken thighs in the marinade, ensuring they're evenly covered. Let them marinate at room temperature for about 15 minutes.
In a large oven-safe skillet, heat a tablespoon of olive oil over medium-high heat. Add the chicken thighs, skin side down.
Sear for about 5-7 minutes until the skin is golden brown. Flip the chicken and sear the other side for an additional 3-4 minutes.
Remove the chicken from the pan, then add the rice and chicken broth to the skillet. Stir well until the rice is evenly distributed.
Place the seared chicken thighs on top of the rice, skin side up, and drizzle any remaining marinade over them.
Transfer the skillet to the preheated oven and bake for 20-25 minutes until the chicken is cooked through and the rice is tender.
Let it rest for 5 minutes before serving. Fluff the rice with a fork and enjoy!
