Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with oil or cooking spray.
In the baking dish, add the uncooked rice, chopped onion, garlic, chicken broth, salt, pepper, and thyme. Stir to combine and evenly distribute the ingredients.
Pat the chicken dry with paper towels. Rub the skin with olive oil or melted butter, then season generously with salt, pepper, and paprika.
Place the chicken thighs on top of the rice mixture, skin-side up. Cover the dish tightly with foil and bake for 50 minutes.
Remove the foil and bake for another 20–25 minutes, or until the chicken skin is crispy and the rice is fully cooked and fluffy.
Remove from the oven and let rest for 5 minutes. Garnish with chopped parsley before serving.
