01 - Heat olive oil in a skillet over medium-high heat. Sear chicken thighs for 2-3 minutes on each side until lightly golden. This step is optional but builds a deeper flavor foundation.
02 - Spread the rinsed rice evenly across the bottom of the slow cooker. Layer diced onion, minced garlic, and diced carrots on top of the rice.
03 - Place the seared chicken thighs over the vegetable and rice layer in the slow cooker.
04 - Sprinkle dried Italian herbs, salt, black pepper, and paprika evenly over the chicken thighs.
05 - Pour the chicken broth, lemon juice, and lemon zest evenly over all the ingredients in the slow cooker.
06 - Cover the slow cooker and cook on High for 4 hours or on Low for 7 hours, until the chicken is cooked through and the rice is fully tender.
07 - Stir in the frozen peas during the last 20 minutes of cooking so they heat through without becoming mushy.
08 - Gently fluff the rice with a fork and garnish with freshly chopped parsley before serving.
