Heat the olive oil in a large Dutch oven over medium-high heat.
Season both sides of the chicken thighs well with garlic powder, sea salt, and freshly cracked pepper, to taste.
Place them skin-side down in the HOT Dutch oven and cook undisturbed for 4-5 minutes or until the skin is golden brown. Flip it over and cook for 2 minutes.
Remove the chicken thighs from the Dutch oven and place them on a plate with a loose foil tent.
Add the butter to the now-empty Dutch oven over medium-high heat.
Add the mushrooms and cook for 2-3 minutes, or until golden.
Add the shallots and cook, stirring often, for 1 minute.
Add the minced garlic and cook, stirring constantly, for 1 minute.
Add the rice to the pan and cook, stirring often, for 1-2 minutes.
Add the chicken broth, water, and broccoli; mix well and season with sea salt and freshly cracked pepper, to taste.
Nestle the chicken thighs back into the Dutch oven, skin side up.
Cover the Dutch oven with a lid and place it in the oven to bake for 20-25 minutes, or until the chicken is cooked through and the rice is done.
Remove the lid and allow to cook for 5 minutes to crisp up the skin.
Remove from the oven and sprinkle with fresh parsley on top, with lemon wedges on the side. Serve and enjoy.
