Add the rinsed rice, broth (or water), and the sea salt to a 3-quart Dutch oven or enameled cast iron with a matching lid and stir to combine.
Lay the chicken thighs on top of the rice. Be sure to create an even layer over the rice with the chicken, and try not to push the chicken down into the rice.
Sprinkle the dish with 1 tablesspoon of your seasoning blend of choice.
Cover the pot with its lid, then bake for 30 minutes. Remove chicken and set on plate. Stir rice, then return chicken. Bake, covered, 15 minutes more.
Uncover the dish and bake for 10 more minutes, until the rice is fully cooked through and the chicken is slightly browned on top.
Remove the dish from the oven, then garnish with lemon or lime juice and fresh herbs, if using, and enjoy!
