In a bowl or large zip-top bag, combine 2 tablespoons extra virgin olive oil, the juice and zest of 1 lemon, 3 tablespoons honey or maple syrup, and 3 tablespoons soy sauce to make the marinade.
Add the 6 chicken thighs to the marinade, seal the bag or cover the bowl, and marinate in the refrigerator for 1 to 6 hours.
Preheat the oven to 375°F (190°C).
Heat a 9- or 10-inch ovenproof skillet over medium-high heat and add 2 tablespoons olive oil. Brown the chicken thighs, skin-side down first, about 3-4 minutes per side until nicely browned. Remove chicken and set aside.
Add the diced onion to the same pan and cook about 6 minutes, stirring occasionally, until softened. Add the minced garlic and cook 1 minute more.
Stir in the uncooked rice and cook for 1 minute to toast lightly. Add 1 tablespoon Italian seasoning, 1 teaspoon lemon zest, and 2 cups low-sodium chicken broth. Stir to combine and scrape any browned bits from the pan.
Return the browned chicken thighs to the pan, placing them skin-side up on top of the rice. Garnish with halved lemons if desired.
Cover the pan tightly with foil and bake in the preheated oven for 45–50 minutes, until the rice is tender and the chicken reaches 165°F (74°C).
When about 5 minutes of cooking remain, remove the foil and broil the pan for 5 minutes to crisp the chicken skin.
Garnish with additional lemon zest and chopped parsley before serving.
