In a large oven-safe skillet or baking dish, heat the olive oil over medium heat.
Season the chicken thighs with paprika, thyme, cumin, salt, and pepper. Place them in the pan and sear for about 5 minutes on each side until golden brown. Remove the chicken and set aside.
In the same pan, add the diced onion, bell pepper, and garlic. Sauté until the onion is translucent, about 3-4 minutes.
Stir in the rice, then pour in the chicken broth. Mix well to combine.
Nestle the chicken thighs back into the skillet with the rice.
Scatter the frozen peas over the top.
Cover the pan with a tight-fitting lid or foil, and bake in the preheated oven for 25-30 minutes, or until the rice is tender and has absorbed the liquid.
Remove from the oven and let it sit covered for 5 minutes. Fluff the rice with a fork.
