Preheat your oven to 400F and make sure you are using an oven-safe skillet with a lid. See example in equipment list.
Place the skillet oven medium-high heat. Drizzle the olive oil into hot skillet.
Gently place the the chicken thighs, smooth side down, into the oil. Cook the thighs on both side to get a nice golden color. The thighs do not have to be fully cooked at this time.
Remove the thighs from the skillet and place them on a clean plate. Turn the heat down to medium, add the chopped onion and garlic into the hot skillet and cook for a couple minutes.
Deglaze the pan by slowly pouring in the chicken broth into the skillet. Scrape off all the stuck on bits from the bottom of the skillet. Stir in the Lemon Mediterranean dressing into the broth and bring everything to a simmer.
Turn off the heat to the skillet. Evenly pour in the uncooked rice into the skillet, making sure that it is as level as possible for even cooking.
Place the chicken thighs (smooth side up) on top of the rice in the skillet, and place a thin slice of lemon on top of each thigh.
Put the lid on the skillet and carefully place it in the preheated oven for 20 minutes. Remove the lid from the skillet and bake for an additional 10 minutes.
Remove the skillet from the oven and let rest for 5 minutes. Drizzle with fresh lemon juice of with more of the Lemon Mediterranean dressing for a boost of citrus flavor. Sprinkle with fresh dill and serve!
