01 - Heat olive oil in a skillet over medium-high heat. Sear chicken thighs for 2–3 minutes per side until lightly golden. This step is optional but develops a deeper, richer flavor.
02 - Spread the rinsed rice evenly across the bottom of the slow cooker. Top with the diced onion, minced garlic, and diced carrots in an even layer.
03 - Place the seared chicken thighs on top of the vegetable and rice layer, skin side up.
04 - Sprinkle the 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 (internal temperature reaches 165°F) and the rice is 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, garnish with fresh chopped parsley, and serve directly from the slow cooker.
