In a large, oven-safe skillet or baking dish, heat the olive oil over medium heat until shimmering.
Generously season both sides of the chicken thighs with salt, pepper, smoked paprika, dried oregano, and turmeric.
Carefully add the chicken thighs, skin-side down, and sear for about 5-7 minutes until golden brown. Flip and sear the other side for an additional 5 minutes. Remove and set aside.
In the same skillet, add the diced onion and sauté for approximately 3-4 minutes until softened. Stir in the minced garlic and sauté for another minute.
Add the long-grain rice to the skillet, stirring well to coat each grain in the onion and garlic mixture. Toast for about 2 minutes.
Gradually pour in the chicken broth and bring to a gentle boil. Stir in the diced red bell pepper and frozen peas.
Place the seared chicken thighs on top of the rice mixture, skin-side up. Cover with a lid or aluminum foil.
Transfer the skillet to the preheated oven and bake for 35-40 minutes, or until the rice is tender and the chicken reaches an internal temperature of at least 165°F (75°C).
Remove from the oven and let it rest for about 5 minutes before serving.
Notes
Garnish with freshly chopped parsley before serving for a vibrant touch.
