Preheat oven to 350°F.
Trim chicken thighs of excess skin (any skin that goes beyond covering the top of the thigh I trim off) and fat. Using a paper towel, blot off any excess moisture and then massage thighs with about 1 tablespoon of EVOO (this process will help avoid the mess that comes with browning the thighs in a skillet!) sprinkle with kosher salt and pepper. Heat (oven safe) skillet over medium high heat and brown the thighs, beginning with the skin side down first, 4-5 minutes for the first side and then 3-4 minutes for reverse side. Once browned, remove thighs to a plate and set aside.
Add another tablespoon of EVOO to skillet and once shimmering add chopped onions. Saute over medium high heat until soft and translucent, about 5 minutes. Add minced garlic and saute for another minute.
Add rice to skillet, stirring about 1 minute until rice is thoroughly coated with oil.
Add ½ cup wine (or broth)and allow to deglaze pan, stirring for another minute or so until any brown bits from the chicken have released from the bottom of the skillet.
Add remaining liquid, lemon zest, thyme salt and pepper. Arrange chicken thighs evenly around skillet, scatter olives and tuck in lemon slices.
Cover skillet (if you have no lid, simply cover with aluminum foil) and place skillet in oven for 30 minutes, uncover and bake an additional 10 minutes.
Garnish with chopped parsley.
