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 builds a deeper flavor base.
02 - Spread rinsed rice evenly across the bottom of the slow cooker. Top with 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, arranging them in a single even layer.
04 - Sprinkle Italian herbs, salt, black pepper, and paprika evenly over the chicken thighs.
05 - Pour chicken broth evenly over all ingredients. Add lemon juice and lemon zest, distributing across the surface.
06 - Cover and cook on High for 4 hours or on Low for 7 hours, until chicken is cooked through (internal temperature reaches 165°F) and rice is fully tender.
07 - Stir frozen peas into the rice during the last 20 minutes of cooking. Replace the lid and continue cooking until heated through.
08 - Gently fluff the rice with a fork. Garnish with freshly chopped parsley and serve directly from the slow cooker.
