Preheat the oven to 400 degrees Fahrenheit (200 degrees Celsius).
Pat chicken thighs dry and season both sides with smoked paprika, cumin, salt, and black pepper.
Heat olive oil in a large oven-safe skillet or Dutch oven over medium-high heat.
Sear the chicken thighs skin-side down for 5 to 6 minutes until the skin is golden and crisp; remove chicken and set aside.
In the same pan, sauté the diced onion and minced garlic for 3 minutes until translucent.
Add the rinsed rice and turmeric to the pan, stirring for 1 minute to toast the grains.
Pour in the chicken broth and stir in the frozen vegetables, ensuring the rice is evenly submerged.
Place the seared chicken thighs on top of the rice mixture, skin-side up.
Cover the pan with a tight-fitting lid or aluminum foil and bake in the oven for 30 minutes.
Remove the cover and bake for an additional 5 to 10 minutes until the liquid is fully absorbed and the chicken reaches an internal temperature of 165 degrees Fahrenheit.
Let the dish rest for 5 minutes before fluffing the rice with a fork and serving.
