01 - Pat the chicken thighs thoroughly dry. Season them generously with sea salt, ground black pepper, smoked paprika, and dried thyme.
02 - In a large, deep skillet or Dutch oven, warm the olive oil over medium-high heat. Sear the seasoned chicken thighs for 3 to 4 minutes per side until they achieve a golden-brown color. Remove the chicken from the skillet and set aside.
03 - Add the diced yellow onion and red bell pepper to the same skillet. Sauté for 3 to 4 minutes, until the vegetables begin to soften. Stir in the minced garlic and cook for an additional minute until fragrant.
04 - Introduce the rinsed long-grain rice to the skillet with the sautéed vegetables. Toast the rice for 1 to 2 minutes, stirring continuously to prevent sticking and to enhance its nutty flavor.
05 - Pour the low-sodium chicken broth into the skillet. Bring the liquid to a gentle simmer, using a wooden spoon to scrape up any flavorful browned bits (fond) adhered to the bottom of the pan.
06 - Return the seared chicken thighs to the skillet. Evenly scatter the halved cherries around the chicken pieces.
07 - Cover the skillet tightly with a lid. Reduce the heat to low and allow the dish to cook for 20 minutes, or until the rice is tender and the chicken is fully cooked through.
08 - Gently stir in the baby spinach, if using. Cover the skillet again and let the spinach wilt for 2 minutes.
09 - Carefully fluff the rice with a fork. Taste and adjust seasonings if necessary. Serve the One-Pot Cherry Chicken Dinner hot.
